  • UIButtonTypeRoundedRect as an accessoryView

    - by phunehehe
    Hello, I have a table view and I want to put a label on the right of each cell, so in - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath I'm having some code like this UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; button.titleLabel.text = @"title"; cell.accessoryView = button; However, the button is not displaying at all. Anyone know why? I am sure that the declaration is correct, because if I replace the button declaration with UIButton *button = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; then the button appears, which make me think that the rounded rectangle should also appear.

  • ASP.Net UpdatePanel, want to have html-tag as a parameter

    - by Nordis
    This is my problem, I have one textbox, one button and one label. Everything is inside an updatepanel. Let's say I want to test if a valid html-tag is entered in the textbox when I press the button. In the code-behind I have a method for that. Everythings works just fine, except when I actually enter a html-tag in my textbox. If I test < html, it works. But not if I test . So my question is, doesn't the updatepanel accept html-tags as parameters? Because my breakpoint for the button_click doesn't triggers. Sorry for my bad english.. :)

  • iphone - calculating the font size

    - by Mike
    I have to show a label with font size = 14 when the view is 480x320. Supposing I would like to do this in a way that my code will be working well for all future device's screen sizes, including iPad and others following (I am sure more will come), what is the best way to do that? I could do this proportionally, I mean, if the scale increased X, increase the fonts X, but my concern is the different aspect ratios of the devices. The iPhone aspect ratio is 1.5, but iPad's is 1.33, and other aspect ratios can come... I am not sure if this simple scale method will be enough to produce font consistency across all devices. Any suggestions? thanks for any help.

  • bigger UITableViewCellStyleValue1 detailTextLabel

    - by Ziga Kranjec
    I am trying to make a UITableView. Table cells are done in style UITableViewCellStyleValue1. When text in either textLabel or detailTextLabel is too long, it gets shortened with ellipsis... This happens for both labels; the problem really occurs, when both labels are too long. What is a preferred way to disable this or make detailTextLabel slightly wider? I want detailTextLabel to always show the entire label (it will be max 6 chars long, so it will fit); textLabel is fine as it is.

  • Equivalents to Z80 DJNZ instruction on other architectures?

    - by Justin Ethier
    First a little background. The z80 CPU has an instruction called DJNZ which can be used in a similar manner as a for loop. Basically DJNZ decrements the B register and jumps to a label if not zero. For example: ld b,96 ; erase all of the line disp_version_erase_loop: call _vputblank ; erase pixels at cursor (uses b reg) djnz disp_version_erase_loop ; loop Of course you can do the same thing using regular comparison and jump instructions, but often it is handy to use the single instruction. With that out of the way, my question is, do other CPU architectures include a similar control instruction?

  • How to show a progress report to the user in Google Apps Script?

    - by Jose M Vidal
    I have a simple script that will send out a bunch of emails but these take time to send and I want to show the user a scrolling window with the emails addresses as they are sent (or, a progress bar would be good too). I believe this is possible with the new User Interface Classes, but I can't get it to work. The documentation is kinda sparse. Specifically, the problem is that the GUI window that pops up appears blank until all the emails have been sent (the script ends) and then the text appears. This happens even if I call show(myapp) after every time I update the Label.

  • Android, simply view question about view reset

    - by javano
    I have a button in my activity, when you click the button an if statement is ran against its text label; if(BTN_1.getText()=="firsttext"){ //do some stuff, then... BTN_1.setText("secondtext"); }else if(BTN_1.getText()=="secondtext"){ //do other stuff, then... BTN_1.setText("firsttext"); } Firstly, if I hit the home button and go back to the desktop and then click back onto my app the view has reset its self; if I press the button and leave it in a state where the text of the button is "secondtext", when I return to my app it says "firsttext", how can I stop the view of my app refreshing its self like this? Secondly, under my XML layout I have defined the buttons text; android:text="firsttext" But this won't actually match my if statement above, under onCreate of this app I have: BTN_CONNECT.setText("Connect"); But visually the text of the button is exactly the same, why won't it match? Thanks for reading :)

  • Force chart labels to remain inside frame

    - by adolf garlic - SAVE BBC6MUSIC
    RS2008 - pie chart I have 'outside' labels with lines pointing to the segment (although strangely this only appears to work in pdf output) However (see pic below) the label is appearing outside the scope of the chart area How can I force it to remain inside? (MinimumRelativePieSize is set to 70) (pic below missing due to not being able to find an image host that isn't blocked by corp firewall) Picture a pie chart of 25 slices, with radial lines that project through the sides. The line from each slice then becomes horizontal, before disappearing outside. (above actually fits tune of "Lucy in the Sky with Diamonds")

    - by Boob
    Im trying to develop my first ASP.NET MVC web app and have run into a problem with the jquery ui autocomplete widget. At the moment I have a form with a number of text boxs which would lend themselves well to an autocomplete ability. The code for my "Make"(Car make) text box is show below: jquery: $(function() { $("#Make").autocomplete({ source: '<%=Url.Action("Make","AutoComplete") %>' }); }); ASP.NET MVC controller: public ActionResult Make(string term) { return Json(Service.GetHints(HintType.Make, term, 20)); } GetHints() returns an IList of Hints, an object with just label and value string properties. The documentation implies that this is what I should be returning to the jquery but it doesnt want to work? Can anyone give me any advice/help?

    I have an employee entity in my EF model. I then added a class to the project to add a custom property public partial class Employee { public string Name { get { return string.Format("{0} {1}", this.FirstName, this.LastName); } } } On a aspx form (inside a FormView), I want to bind a DropDownList to the employee collection: <asp:Label runat="server" AssociatedControlID="ddlManagerId" Text="ManagerId" /> <asp:DropDownList ID="ddlManagerId" runat="server" DataSourceID="edsManagerId" DataValueField="Id" DataTextField="Name" AppendDataBoundItems="true" SelectedValue='<%# Bind("ManagerId") %>'> <asp:ListItem Text="-- Select --" Value="0" /> </asp:DropDownList> <asp:EntityDataSource ID="edsManagerId" runat="server" ConnectionString="name=Entities" DefaultContainerName="Entities" EntitySetName="Employees" EntityTypeFilter="Employee" EnableFlattening="true"> </asp:EntityDataSource> Unfortunately, when I fire up the page, I get an error: DataBinding: 'System.Web.UI.WebControls.EntityDataSourceWrapper' does not contain a property with the name 'Name'.

  • Best approch for creating Base control

    - by akjoshi
    Hi, I am looking for a solution for this scenario - I need to implement a feature to allow user to add various controls to canvas(WPF, custom and third party ) and then select any one of them and modify some properties in property grid(changes needs to be reflected in UI). I don't want to expose all the properties of any control only some of them(relevant to end user); apart from this there are some properties which will be common for all controls e.g. Title, Value(Value will be bound to some property of a control, say Text of TextBox and Content of Label) etc. I am thinking of putting all the common proeprties at one place. Things I am confused aout - How to create such base class, whether to use UserControl or Custom Control for this? How will the binding work between Control, base class proeprties and PropertyGrid? What type of object will I expose to property grid? Any idea on what approch should be followed in this case, any kind of input will really be helpful.

  • Eclipse standard warning/error overlay icons

    - by pulzar
    I'm writing an Eclipse plug-in... In my custom label decorator, I want to overlay a warning icon, and I'd like to use the standard one used by eclipse (the little yellow triangle). How can I get an image descriptor of this icon? I tried using workbench.getSharedImages().getImageDescriptor(ISharedImages .IMG_DEC_FIELD_WARNING), since that ID seems to match what I'm looking for, but the shared images collection doesn't actually have that image in it (so I just get a null returned). Is there some other shared image collection that I should be looking at?

  • Flex AdvancedDataGrid with Grouping, how do I get objects to appear under first GroupingField if the

    - by shadenite
    I am using an AdvancedDataGrid with two GroupingFields. The dataProvider has a list of objects with these two field values, but occasionally the second field value can be null. When it loads, the AdvancedDataGrid UI has a root folder (first GroupingField) and some additional subfolders (second GroupingField). This is all good. However, the objects with a null value for the second GroupingField, just get placed in a subfolder with no label. I want the objects with a null second GroupingField value to appear as leaf nodes beneath the root folder (first GroupingField) minus the blank subfolder. A good way to picture this would be a file explorer. Is there a good way to do this? Make the folder icon disappear maybe after expanding this node through actionscript? ParentFolder SubFolder Leaf Object Leaf Object SubFolder Leaf Object Leaf Object Leaf Object

  • Pass easing function as variable in AS3

    - by Andrej
    Hi, I've been looking for some time now.. Is is possible to pass easing function as variable in AS3? eg. TweenLite.to(mcDelimiter, resizeTween, { x:(stageWidthHalf-(initStageWidthHalf-mcDelimiteri_X)), ease:Elastic.easeOut } ); TweenLite.to(mcBody, resizeTween, { x:(stageWidthHalf-(initStageWidthHalf-mcBody_X)), ease:Elastic.easeOut } ); ... now if I at some point want to change "Elastic.easeOut" to something else I would have to change it at multiple parts of the code.. Can it be done so I just pass it as a variable and then if I want to change it, do it only on one place? EDIT: ...also, can for eg. if(currentFrame == "FrameLabel") somehow be done? ..meaning, can I pass the currentFrame label name as a variable? Thanks in advance for anwsers, Andrej

  • PushViewController after presentModalViewController like in Apples Alarm Clock app

    - by Fabian
    Hello together, my Question is quite simple. I have an add-button. When I tap on it -- presentmodelviewController presents a UIViewController, which contains a simple Table with cells. When I tap on a Cell, i want to display a new View using pushViewController, which automatically creates a "back Button". At the top of it in this new View i have a Textfield, where I can enter some Text. When I tap the back-button, the view slides back to the add-View (which was presented using modalView...). Now i want the text edited in the view before to be placed in the Label of the first row (cell) on which I tapped. So I want to do this for 5 cells. Each of them presenting another xib. Please, can anyone help? Thanks for your helpful replies.

  • C++ Switch Statement Case Error

    - by Metal_Drummer
    I'm programming a simple text-based RPG using a switch statement for a game loop. The program works fine until I attempt to add another case statement, at which point it gives me the following three errors: "jump to case label" (error occurs at the line of the newly added case), and two "crosses initialization of 'ClassName *objectName'"(errors occur when the new objects are created in case 2). I'll paste the important code, if anyone needs more, please let me know. int main(void) { //initiate first object array and add some objects //initiate second object array and add some objects while(gamestate != 8) { switch(gamestate) { case 0: //do some stuff break; case 1: //do some stuff break; case 2: //declare new objects of the two... //...classes I have (ClassName *objectName) //do some stuff break; case 3: //this is the case I am trying to add //do nothing break; } } return 0; }
