  • Java Swt Text (SWT.MULTI) append text without scroll

    - by mchr
    I have a Java SWT GUI with a multiline Text control. I want to append lines of text to the Text control without affecting the position of the cursor within the text box. In particular, the user should be able to scroll and select text at the top of the Text control while new text lines are appended to the bottom. Is this possible?

  • [C#] how do I get the height of a rich text content after word wrap?

    - by Led
    Question A. Given 1. A string in rich text format that may have paragraph, tabs, space, line break, indentation, (or even image?) 2. A width for the word wrapping rich text control/editor How do I know the height of the content after it have performed all the word wrapping? Is there something like int MeasureRichTextHeightAfterWordWrap(string aRichTextContent, int aWidth)? Otherwise how does those rich text control know how much to autosize? Do I have to actually place the content on a dummy rich text control and get its height afterwards? Question B. Similar to question A but in plain text onto a plain text memo/control/editor. And manually draw string with manually calculated indentations, breaks, word wrappings. Is it easier or harder?

  • CSS: Labels in table columns

    - by hello
    Hello. BACKGROUND: I would like to have small labels in columns of a table. I'm using some implemented parts of HTML5/CSS3 in my project, and this section specifically is for mobile devices. While both facts are not necessarily relevant, the bottom line is that I don't have to support Internet Explorer or even Firefox for that matter (just WebKit). THE PROBLEM With my current CSS approach, the vertical padding of the cell comes from the <span element (set to display: block with top/bottom margins), which contains the "value" of the column. As a result there's no padding when the <span> is empty or missing (no value) and the label is not in place. The "full" coulmns should give you the idea of where I want the labels to be, even if there's no value, and the <span> is not there. I realize that I could use "non-breaking-space", but I would really like to avoid it. I wonder if any of you have a fix / better way to do this? current code is below. Thank you for any help. <!DOCTYPE html> <html lang="en"> <head> <title>ah</title> <style> body { width: 320px; } /* TABLE */ table { width: 100%; border-collapse: collapse; font-family: arial; } th, td { border: 1px solid #ccc; border-width: 0px 0px 1px 1px; } th:last-child, td:last-child { border-right-width: 1px; } tr:first-child th { border-top-width: 1px; background: #efefef; } /* RELEVANT STUFF */ td { padding: 3px; } td sup { display: block; } td span { display: block; margin: 3px 0px; text-align: center; } </style> </head> <body> <table> <tr> <th colspan="3">something</th> </tr> <tr> <td><sup>some label</sup><span>any content</span></td> <td><sup>some label</sup><span>any content</span></td> <td><sup>some label</sup><span></span></td><!-- No content, just a label --> </tr> </table> </body> </html>

  • Activate a (COM Interop based) ActiveX contol using registration free com

    - by embnut
    I have a (COM Interop based) ActiveX contol that I am trying to use with registration free com. When the control loads the control is inactive (does not responds to events, control not fully rendered etc). After much search I discovered that COM objects using reg-free-com use the miscStatus attribute to set the initial state to get correctly activated. I know how to use it with a comClass which corresponds to a native COM Object. 1) What is the equivalent of the following for clrClass element which corresponds to a COM-interop object? <comClass clsid="{qqqqqqqq-wwww-eeee-rrrr-00C0F0283628}" tlbid="{xxxxxxxx-yyyy-zzzz-aaaa-0000F8754DA1}" threadingModel="Both" progid="SomeCompany.SomeOleControl" description="Some ActiveX Control" miscStatus="recomposeonresize,insideout,activatewhenvisible,nouiactivate" > 2) The COM client I am using is Visual FoxPro. If the (1) is not possible what can I do in VFP to activate the inactive ActiveX control. (I dont mind VB or C# input too if I can use it to find the equivalent foxpro) Currently I tried the following this.AddObject('OleControl1', 'oleControl', 'SomeCompany.SomeOleControl') this.OleControl1.AutoActivate = 3 this.OleControl1.Visible = .T. this.OleControl1.SetFocus But I the OleControl1 gets focus before passing events like mouse click to its subelements. So I have to click twice on it to do the necessary action, any time it does not have focus. I would like the control to act as if the "nouiactivate" of the miscStatus value is set. 3) Is there any other way of accomplishing what I want to do? Hans Passant, here is the listing of current Assembly.dll.manifest. The formatting in the comment made it unreadable. <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity name="Assembly" version="1.0.0.0" type="win32" publicKeyToken="wwwwwwwwwwwwwwww"/> <clrClass name="SomeCompany.SomeOleControl" clsid="{qqqqqqqq-wwww-eeee-rrrr-00C0F0283628}" progid="SomeCompany.SomeOleControl" threadingModel="Both"/> <file name="Assembly.tlb"> <typelib tlbid="{xxxxxxxx-yyyy-zzzz-aaaa-0000F8754DA1}" version="1.0" helpdir="" flags="hasdiskimage"/> </file> </assembly>

  • ScrollBars are not visible after changing positions of controls inside a Canvas

    - by akjoshi
    Hi, I created a custom canvas control inheriting from WPF Canvas. I am using it like this in main window - <ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto"> <RTD:RTDesignerCanvas Margin="5" Background="White" x:Name="canvas1" Focusable="True" AllowDrop="True"> </RTD:RTDesignerCanvas> </ScrollViewer> Everyhting works fine but when I try to set the position of controls inside it like this Canvas.SetTop(item, 200); scrollbars are not visible and control is hiddedn down somewhere. Intrestingly, if I add another control to it scroll bars are visible and I can scroll downwards to see the previous control. I tried to use base.InvalidateVisual(); base.UpdateLayout(); base.InvalidateArrange(); after changing items Top or Left but nothing happens; Am I missing something or this happens due to some bug?

  • Goto for the Java Programming Language

    - by darcy
    Work on JDK 8 is well-underway, but we thought this late-breaking JEP for another language change for the platform couldn't wait another day before being published. Title: Goto for the Java Programming Language Author: Joseph D. Darcy Organization: Oracle. Created: 2012/04/01 Type: Feature State: Funded Exposure: Open Component: core/lang Scope: SE JSR: 901 MR Discussion: compiler dash dev at openjdk dot java dot net Start: 2012/Q2 Effort: XS Duration: S Template: 1.0 Reviewed-by: Duke Endorsed-by: Edsger Dijkstra Funded-by: Blue Sun Corporation Summary Provide the benefits of the time-testing goto control structure to Java programs. The Java language has a history of adding new control structures over time, the assert statement in 1.4, the enhanced for-loop in 1.5,and try-with-resources in 7. Having support for goto is long-overdue and simple to implement since the JVM already has goto instructions. Success Metrics The goto statement will allow inefficient and verbose recursive algorithms and explicit loops to be replaced with more compact code. The effort will be a success if at least twenty five percent of the JDK's explicit loops are replaced with goto's. Coordination with IDE vendors is expected to help facilitate this goal. Motivation The goto construct offers numerous benefits to the Java platform, from increased expressiveness, to more compact code, to providing new programming paradigms to appeal to a broader demographic. In JDK 8, there is a renewed focus on using the Java platform on embedded devices with more modest resources than desktop or server environments. In such contexts, static and dynamic memory footprint is a concern. One significant component of footprint is the code attribute of class files and certain classes of important algorithms can be expressed more compactly using goto than using other constructs, saving footprint. For example, to implement state machines recursively, some parties have asked for the JVM to support tail calls, that is, to perform a complex transformation with security implications to turn a method call into a goto. Such complicated machinery should not be assumed for an embedded context. A better solution is just to expose to the programmer the desired functionality, goto. The web has familiarized users with a model of traversing links among different HTML pages in a free-form fashion with some state being maintained on the side, such as login credentials, to effect behavior. This is exactly the programming model of goto and code. While in the past this has been derided as leading to "spaghetti code," spaghetti is a tasty and nutritious meal for programmers, unlike quiche. The invokedynamic instruction added by JSR 292 exposes the JVM's linkage operation to programmers. This is a low-level operation that can be leveraged by sophisticated programmers. Likewise, goto is a also a low-level operation that should not be hidden from programmers who can use more efficient idioms. Some may object that goto was consciously excluded from the original design of Java as one of the removed feature from C and C++. However, the designers of the Java programming languages have revisited these removals before. The enum construct was also left out only to be added in JDK 5 and multiple inheritance was left out, only to be added back by the virtual extension method methods of Project Lambda. As a living language, the needs of the growing Java community today should be used to judge what features are needed in the platform tomorrow; the language should not be forever bound by the decisions of the past. Description From its initial version, the JVM has had two instructions for unconditional transfer of control within a method, goto (0xa7) and goto_w (0xc8). The goto_w instruction is used for larger jumps. All versions of the Java language have supported labeled statements; however, only the break and continue statements were able to specify a particular label as a target with the onerous restriction that the label must be lexically enclosing. The grammar addition for the goto statement is: GotoStatement: goto Identifier ; The new goto statement similar to break except that the target label can be anywhere inside the method and the identifier is mandatory. The compiler simply translates the goto statement into one of the JVM goto instructions targeting the right offset in the method. Therefore, adding the goto statement to the platform is only a small effort since existing compiler and JVM functionality is reused. Other language changes to support goto include obvious updates to definite assignment analysis, reachability analysis, and exception analysis. Possible future extensions include a computed goto as found in gcc, which would replace the identifier in the goto statement with an expression having the type of a label. Testing Since goto will be implemented using largely existing facilities, only light levels of testing are needed. Impact Compatibility: Since goto is already a keyword, there are no source compatibility implications. Performance/scalability: Performance will improve with more compact code. JVMs already need to handle irreducible flow graphs since goto is a VM instruction.

I have another control Gridview along with checkbox's which require postback to get populated. Once It gets populated successfully inside update without postback. I checked few rows and wanted to add them into List Control using Javascript. It says "object doesn't support this property or method" function addItmList(idv,valItem) { var list =document.getElementById('ctl00_ContentPlaceHolder1_MyList'); //var generatedName = "newItem" + ( list.options.length + 1 ); list.Add(idv,valItem); } function checkitemvalues() { var gvET = document.getElementById("ctl00_ContentPlaceHolder1_grd"); var target = document.getElementById('ctl00_ContentPlaceHolder1_lstIControl'); var newOption = window.document.createElement('OPTION'); var rCount = gvET.rows.length; var rowIdx = 0; var tcount = 1; for (rowIdx; rowIdx<=rCount-1; rowIdx++) { var rowElement = gvET.rows[rowIdx]; var chkBox = rowElement.cells[0].firstChild; var cod = rowElement.cells[1].innerText; var desc = rowElement.cells[2].innerText; if (chkBox.checked == true){ addItmList(rowElement.cells[1].innerText,rowElement.cells[2].innerText); } } } Code Behind ScriptManager.RegisterClientScriptBlock( Me.Page, Me.GetType(), MyList.ClientID, "" & vbCr & vbLf & "window.mylistid='" + MyList.ClientID + "';" & vbCr & vbLf & "", True ) Remember my code works fine. It cannot maintain the state of List Control thats why It says Object reqiured. Can any one help me out. After Update Panel Why My javascript doesnt add Items into ListBox. Thanks In advance

  • ActiveX controls with old Delphi versions

    - by DamienD
    I'm testing a non visual ActiveX control based on a registered .ocx which I import into Delphi using the provided wizard. Then, I simply put the generated component on the main form of a new VCL application. Under old Delphi versions (D5 and D2007), when i launch the application, this raise an AV during the component initialization. with Delphi 2009 : no problem, the application starts smoothly. My questions are : Are there known enhancements of ActiveX management in recent Delphi versions which can explain this difference ? Can I suspect a bug in the ActiveX control, or can I consider the origin of the problem is from old Delphi versions ? I need to use this component (if tests OK) in D2007. Do you think that it is possible to correct the AV problem under D2007 by modifying the D2007 generated .tlb file (for example by trying to use the D2009 generated one) PS: the ActiveX control is not named, because my question is a general question about Delphi and ActiveX, not about a specific ActiveX control.

  • How to make TinyMCE work inside an UpdatePanel?

    - by lucian.jp
    I'm trying to do something that many people seem to have been able to do but which I am unable to implement any solution. The TinyMCE control works pretty well in an asp.net form until you enclose it with an UpdatePanel, which then breaks after postback. I have tried some fixes like the RegisterClientScriptBlock method, but am still unsuccessful, I still lose the tinyMCE control after postback. Below is a full test project (VS 2008) provided with a Control outside UpdatePanel and one inside, with a button on each to generate postback. Also in the project I have a EditorTest control which include commented code of some calls I tried, in case it gives anyone any ideas. CODE SAMPLE Here are some sources for some solutions on the MCE forum : AJAX UpdatePanel

  • UserControl Shadow

    - by noober
    Hello all, I have a user control, MBControl. Here is the code: <my:MBControl Name="MBControl" HorizontalAlignment="Center" VerticalAlignment="Center"> <my:MBControl.BitmapEffect> <DropShadowBitmapEffect Color="Black" Direction="315" Softness="0.5" ShadowDepth="10" Opacity="1" /> </my:MBControl.BitmapEffect> </my:MBControl> The problem with the code is it seems like the shadow is applied to every child element of my user control. Or, possibly, it is dropped inside as well as outside -- the control surface is darker than without the shadow. How could I fix this? I want the shadow being dropped outside only and not affecting the control surface.

  • Using Build Manager Class to Load ASPX Files and Populate its Controls

    - by Sandhurst
    I am using BuildManager Class to Load a dynamically generated ASPX File, please note that it does not have a corresponding .cs file. Using Following code I am able to load the aspx file, I am even able to loop through the control collection of the dynamically created aspx file, but when I am assigning values to controls they are not showing it up. for example if I am binding the value "Dummy" to TextBox control of the aspx page, the textbox remains empty. Here's the code that I am using protected void Page_Load(object sender, EventArgs e) { LoadPage("~/Demo.aspx"); } public static void LoadPage(string pagePath) { // get the compiled type of referenced path Type type = BuildManager.GetCompiledType(pagePath); // if type is null, could not determine page type if (type == null) throw new ApplicationException("Page " + pagePath + " not found"); // cast page object (could also cast an interface instance as well) // in this example, ASP220Page is a custom base page System.Web.UI.Page pageView = (System.Web.UI.Page)Activator.CreateInstance(type); // call page title pageView.Title = "Dynamically loaded page..."; // call custom property of ASP220Page //pageView.InternalControls.Add( // new LiteralControl("Served dynamically...")); // process the request with updated object ((IHttpHandler)pageView).ProcessRequest(HttpContext.Current); LoadDataInDynamicPage(pageView); } private static void LoadDataInDynamicPage(Page prvPage) { foreach (Control ctrl in prvPage.Controls) { //Find Form Control if (ctrl.ID != null) { if (ctrl.ID.Equals("form1")) { AllFormsClass cls = new AllFormsClass(); DataSet ds = cls.GetConditionalData("1"); foreach (Control ctr in ctrl.Controls) { if (ctr is TextBox) { if (ctr.ID.Contains("_M")) { TextBox drpControl = (TextBox)ctr; drpControl.Text = ds.Tables[0].Rows[0][ctr.ID].ToString(); } else if (ctr.ID.Contains("_O")) { TextBox drpControl = (TextBox)ctr; drpControl.Text = ds.Tables[1].Rows[0][ctr.ID].ToString(); } } } } } } }

  • How do you 'clone' WebControls in C# .NET ?

    - by Adz
    My basic question is, in .NET, how do I clone WebControls? I would like to build a custom tag, which can produce multiple copies of its children. Ultimately I intend to build a tag similar to in JSP/Struts. But the first hurdle I have is the ability to duplicate/clone the contents of a control. Consider this rather contrived example; <custom:duplicate count="2"> <div> <p>Some html</p> <asp:TextBox id="tb1" runat="server" /> </div> </custom:duplicate> The HTML markup which is output would be something like, <div> <p>Some html</p> <input type="text" id="tb1" /> </div> <div> <p>Some html</p> <input type="text" id="tb1" /> </div> Note: I know i have the id duplicated, I can come up with a solution to that later! So what we would have is my custom control with 3 children (I think) - a literal control, a TextBox control, and another literal control. In this example I have said 'count=2' so what the control should do is output/render its children twice. What I would hope to do is write some "OnInit" code which does something like: List<WebControl> clones; for(int i=1; i<count; i++) { foreach(WebControl c in Controls) { WebControl clone = c.Clone(); clones.Add(clone); } } Controls.AddRange(clones); However, as far as I can tell, WebControls do not implement ICloneable, so its not possible to clone them in this way. Any ideas how I can clone WebControls?

  • How Visual Studio 2010 and Team Foundation Server enable Compliance

    - by Martin Hinshelwood
    One of the things that makes Team Foundation Server (TFS) the most powerful Application Lifecycle Management (ALM) platform is the traceability it provides to those that use it. This traceability is crucial to enable many companies to adhere to many of the Compliance regulations to which they are bound (e.g. CFR 21 Part 11 or Sarbanes–Oxley.)   From something as simple as relating Tasks to Check-in’s or being able to see the top 10 files in your codebase that are causing the most Bugs, to identifying which Bugs and Requirements are in which Release. All that information is available and more in TFS. Although all of this tradability is available within TFS you do need to understand that it is not for free. Well… I say that, but if you are using TFS properly you will have this information with no additional work except for firing up the reporting. Using Visual Studio ALM and Team Foundation Server you can relate every line of code changes all the way up to requirements and back down through Test Cases to the Test Results. Figure: The only thing missing is Build In order to build the relationship model below we need to examine how each of the relationships get there. Each member of your team from programmer to tester and Business Analyst to Business have their roll to play to knit this together. Figure: The relationships required to make this work can get a little confusing If Build is added to this to relate Work Items to Builds and with knowledge of which builds are in which environments you can easily identify what is contained within a Release. Figure: How are things progressing Along with the ability to produce the progress and trend reports the tractability that is built into TFS can be used to fulfil most audit requirements out of the box, and augmented to fulfil the rest. In order to understand the relationships, lets look at each of the important Artifacts and how they are associated with each other… Requirements – The root of all knowledge Requirements are the thing that the business cares about delivering. These could be derived as User Stories or Business Requirements Documents (BRD’s) but they should be what the Business asks for. Requirements can be related to many of the Artifacts in TFS, so lets look at the model: Figure: If the centre of the world was a requirement We can track which releases Requirements were scheduled in, but this can change over time as more details come to light. Figure: Who edited the Requirement and when There is also the ability to query Work Items based on the History of changed that were made to it. This is particularly important with Requirements. It might not be enough to say what Requirements were completed in a given but also to know which Requirements were ever assigned to a particular release. Figure: Some magic required, but result still achieved As an augmentation to this it is also possible to run a query that shows results from the past, just as if we had a time machine. You can take any Query in the system and add a “Asof” clause at the end to query historical data in the operational store for TFS. select <fields> from WorkItems [where <condition>] [order by <fields>] [asof <date>] Figure: Work Item Query Language (WIQL) format In order to achieve this you do need to save the query as a *.wiql file to your local computer and edit it in notepad, but one imported into TFS you run it any time you want. Figure: Saving Queries locally can be useful All of these Audit features are available throughout the Work Item Tracking (WIT) system within TFS. Tasks – Where the real work gets done Tasks are the work horse of the development team, but they only as useful as Excel if you do not relate them properly to other Artifacts. Figure: The Task Work Item Type has its own relationships Requirements should be broken down into Tasks that the development team work from to build what is required by the business. This may be done by a small dedicated group or by everyone that will be working on the software team but however it happens all of the Tasks create should be a Child of a Requirement Work Item Type. Figure: Tasks are related to the Requirement Tasks should be used to track the day-to-day activities of the team working to complete the software and as such they should be kept simple and short lest developers think they are more trouble than they are worth. Figure: Task Work Item Type has a narrower purpose Although the Task Work Item Type describes the work that will be done the actual development work involves making changes to files that are under Source Control. These changes are bundled together in a single atomic unit called a Changeset which is committed to TFS in a single operation. During this operation developers can associate Work Item with the Changeset. Figure: Tasks are associated with Changesets   Changesets – Who wrote this crap Changesets themselves are just an inventory of the changes that were made to a number of files to complete a Task. Figure: Changesets are linked by Tasks and Builds   Figure: Changesets tell us what happened to the files in Version Control Although comments can be changed after the fact, the inventory and Work Item associations are permanent which allows us to Audit all the way down to the individual change level. Figure: On Check-in you can resolve a Task which automatically associates it Because of this we can view the history on any file within the system and see how many changes have been made and what Changesets they belong to. Figure: Changes are tracked at the File level What would be even more powerful would be if we could view these changes super imposed over the top of the lines of code. Some people call this a blame tool because it is commonly used to find out which of the developers introduced a bug, but it can also be used as another method of Auditing changes to the system. Figure: Annotate shows the lines the Annotate functionality allows us to visualise the relationship between the individual lines of code and the Changesets. In addition to this you can create a Label and apply it to a version of your version control. The problem with Label’s is that they can be changed after they have been created with no tractability. This makes them practically useless for any sort of compliance audit. So what do you use? Branches – And why we need them Branches are a really powerful tool for development and release management, but they are most important for audits. Figure: One way to Audit releases The R1.0 branch can be created from the Label that the Build creates on the R1 line when a Release build was created. It can be created as soon as the Build has been signed of for release. However it is still possible that someone changed the Label between this time and its creation. Another better method can be to explicitly link the Build output to the Build. Builds – Lets tie some more of this together Builds are the glue that helps us enable the next level of tractability by tying everything together. Figure: The dashed pieces are not out of the box but can be enabled When the Build is called and starts it looks at what it has been asked to build and determines what code it is going to get and build. Figure: The folder identifies what changes are included in the build The Build sets a Label on the Source with the same name as the Build, but the Build itself also includes the latest Changeset ID that it will be building. At the end of the Build the Build Agent identifies the new Changesets it is building by looking at the Check-ins that have occurred since the last Build. Figure: What changes have been made since the last successful Build It will then use that information to identify the Work Items that are associated with all of the Changesets Changesets are associated with Build and change the “Integrated In” field of those Work Items . Figure: Find all of the Work Items to associate with The “Integrated In” field of all of the Work Items identified by the Build Agent as being integrated into the completed Build are updated to reflect the Build number that successfully integrated that change. Figure: Now we know which Work Items were completed in a build Now that we can link a single line of code changed all the way back through the Task that initiated the action to the Requirement that started the whole thing and back down to the Build that contains the finished Requirement. But how do we know wither that Requirement has been fully tested or even meets the original Requirements? Test Cases – How we know we are done The only way we can know wither a Requirement has been completed to the required specification is to Test that Requirement. In TFS there is a Work Item type called a Test Case Test Cases enable two scenarios. The first scenario is the ability to track and validate Acceptance Criteria in the form of a Test Case. If you agree with the Business a set of goals that must be met for a Requirement to be accepted by them it makes it both difficult for them to reject a Requirement when it passes all of the tests, but also provides a level of tractability and validation for audit that a feature has been built and tested to order. Figure: You can have many Acceptance Criteria for a single Requirement It is crucial for this to work that someone from the Business has to sign-off on the Test Case moving from the  “Design” to “Ready” states. The Second is the ability to associate an MS Test test with the Test Case thereby tracking the automated test. This is useful in the circumstance when you want to Track a test and the test results of a Unit Test designed to test the existence of and then re-existence of a a Bug. Figure: Associating a Test Case with an automated Test Although it is possible it may not make sense to track the execution of every Unit Test in your system, there are many Integration and Regression tests that may be automated that it would make sense to track in this way. Bug – Lets not have regressions In order to know wither a Bug in the application has been fixed and to make sure that it does not reoccur it needs to be tracked. Figure: Bugs are the centre of their own world If the fix to a Bug is big enough to require that it is broken down into Tasks then it is probably a Requirement. You can associate a check-in with a Bug and have it tracked against a Build. You would also have one or more Test Cases to prove the fix for the Bug. Figure: Bugs have many associations This allows you to track Bugs / Defects in your system effectively and report on them. Change Request – I am not a feature In the CMMI Process template Change Requests can also be easily tracked through the system. In some cases it can be very important to track Change Requests separately as an Auditor may want to know what was changed and who authorised it. Again and similar to Bugs, if the Change Request is big enough that it would require to be broken down into Tasks it is in reality a new feature and should be tracked as a Requirement. Figure: Make sure your Change Requests only Affect Requirements and not rewrite them Conclusion Visual Studio 2010 and Team Foundation Server together provide an exceptional Application Lifecycle Management platform that can help your team comply with even the harshest of Compliance requirements while still enabling them to be Agile. Most Audits are heavy on required documentation but most of that information is captured for you as long a you do it right. You don’t even need every team member to understand it all as each of the Artifacts are relevant to a different type of team member. Business Analysts manage Requirements and Change Requests Programmers manage Tasks and check-in against Change Requests and Bugs Testers manage Bugs and Test Cases Build Masters manage Builds Although there is some crossover there are still rolls or “hats” that are worn. Do you thing this is all achievable? Have I missed anything that you think should be there?

  • Wrong background colors in Swing ListCellRenderer

    - by Johannes Rössel
    I'm currently trying to write a custom ListCellRenderer for a JList. Unfortunately, nearly all examples simply use DefaultListCellRenderer as a JLabel and be done with it; I needed a JPanel, however (since I need to display a little more info than just an icon and one line of text). Now I have a problem with the background colors, specifically with the Nimbus PLAF. Seemingly the background color I get from list.getBackground() is white, but paints as a shade of gray (or blueish gray). Outputting the color I get yields the following: Background color: DerivedColor(color=255,255,255 parent=nimbusLightBackground offsets=0.0,0.0,0.0,0 pColor=255,255,255 However, as can be seen, this isn't what gets painted. It obviously works fine for the selected item. Currently I even have every component I put into the JPanel the cell renderer returns set to opaque and with the correct foreground and background colors—to no avail. Any ideas what I'm doing wrong here? ETA: Example code which hopefully runs. public class ParameterListCellRenderer implements ListCellRenderer { @Override public Component getListCellRendererComponent(JList list, Object value, int index, boolean isSelected, boolean cellHasFocus) { // some values we need Border border = null; Color foreground, background; if (isSelected) { background = list.getSelectionBackground(); foreground = list.getSelectionForeground(); } else { background = list.getBackground(); foreground = list.getForeground(); } if (cellHasFocus) { if (isSelected) { border = UIManager.getBorder("List.focusSelectedCellHighlightBorder"); } if (border == null) { border = UIManager.getBorder("List.focusCellHighlightBorder"); } } else { border = UIManager.getBorder("List.cellNoFocusBorder"); } System.out.println("Background color: " + background.toString()); JPanel outerPanel = new JPanel(new BorderLayout()); setProperties(outerPanel, foreground, background); outerPanel.setBorder(border); JLabel nameLabel = new JLabel("Factory name here"); setProperties(nameLabel, foreground, background); outerPanel.add(nameLabel, BorderLayout.PAGE_START); Box innerPanel = new Box(BoxLayout.PAGE_AXIS); setProperties(innerPanel, foreground, background); innerPanel.setAlignmentX(Box.LEFT_ALIGNMENT); innerPanel.setBorder(BorderFactory.createEmptyBorder(0, 10, 0, 0)); JLabel label = new JLabel("param: value"); label.setFont(label.getFont().deriveFont( AffineTransform.getScaleInstance(0.95, 0.95))); setProperties(label, foreground, background); innerPanel.add(label); outerPanel.add(innerPanel, BorderLayout.CENTER); return outerPanel; } private void setProperties(JComponent component, Color foreground, Color background) { component.setOpaque(true); component.setForeground(foreground); component.setBackground(background); } } The weird thing is, if I do if (isSelected) { background = new Color(list.getSelectionBackground().getRGB()); foreground = new Color(list.getSelectionForeground().getRGB()); } else { background = new Color(list.getBackground().getRGB()); foreground = new Color(list.getForeground().getRGB()); } it magically works. So maybe the DerivedColor with nimbusLightBackground I'm getting there may have trouble?

  • Why does Ubuntu Download recommend 32-bit install?

    - by Warren Pena
    The Ubuntu desktop download screen has a pair of radio buttons you use to select whether you wish to download the 32-bit or 64-bit version. The 64-bit version is labeled "Not recommended for daily desktop usage." If you have a 64-bit processor, why would you not want to use the 64-bit version of Ubuntu? Update for 10.10: They've removed the "Not recommended" label from the 64-bit version and added a "Recommended" label to the 32-bit version. Update for 11.04: Same as 10.10. Update for 12.04: Still says "Recommended" next to 32-bit version of desktop
