  • loading custom view using loadNibNamed showing memory leaks

    - by user307550
    I have a number of custom table cells and views that I built using interface builder In interface builder, everything is set up similarly. There is a table cell and a couple other UILabels and a background image Object owner if the nib is NSObject Class for the table cell is the name of the class for my table cell Here is how I create the table cell in my code: SectionedSwitchTableCell *cell = nil; NSArray *nibs = [[NSBundle mainBundle] loadNibNamed:kSectionedSwitchTableCellIdentifier owner:owner options:nil]; for(id currentObject in nibs) { if([currentObject isKindOfClass:[SectionedSwitchTableCell class]]) { cell = (SectionedSwitchTableCell *)currentObject; break; } } return cell; For my custom table headers I have this NSArray *nibs = [[NSBundle mainBundle] loadNibNamed:@"CustomTableHeader" owner:self options:nil]; for(id currentObject in nibs) { if([currentObject isKindOfClass:[CustomTableHeader class]]) { return header } } In my .h and .m files for the custom view, I have IBOutlet, @property set up for everything except for the background image UIImageView. Everything that has the IBOutlet and @property are also @synthesized and released in the .m file. Leaks is showing that I have memory leaks with CALayer when I create these custom view objects. Am I doing something wrong here when I create these custom view objects? I'm kind of tearing my hair out trying to figure out where these leaks are coming from. As a side note, I have a UIImageView background image defined in these custom views but I didn't define properties and IBOutlets in my .h and .m files. Defining them doesn't make a difference when I run it through Leaks but just wanted to confirm if I'm doing the right thing. Any input would be super helpful. Thanks :)

  • javascript equivalent of ASP preInit event

    - by Pankaj Kumar
    Hi guys, searching for this has yielded no resuts.. i have a middle page that has an iframe and all the pages open in that iframe...i have to implement a chat system just like in Google and so to ensure that the chat windows did not close whwn the page would postback i am opening all pages in iframe.... this is a social networking site and user can have themes which have background images per theme now when i visit a friends profile the backgrounf image of the middle page should change... i have this code to find parent of iframe and change background image $(document).ready(function(){ var theme=document.getElementById("ctl00_decideFooterH").value; var t= parent.document.getElementsByTagName("body"); if(theme=='basicTheme'){ t[0].className="basic"; } else if(theme=='Tranquility') { t[0].className="Tranquility"; } else if(theme=='AbstractPink') { t[0].className="abstractPink"; } }); and this code is the master page that all child pages that would open in iframe would access..the trouble is that there is a lag between the theme application on server side(which happens at PreInit) and the background image change which is done by this document.ready that gets executed after the iframe has loaded.. so essentially i need a javascript function that would either execute parallel to PreInit or some other logic....so guys plz help its urgent

  • JavaFX 2.0 - How to change legend color of a LineChart dynamically?

    - by marie
    I am trying to style my JavaFX linechart but I have some trouble with the legend. I know how to change the legend color of a line chart in the css file: .default-color0.chart-series-line { -fx-stroke: #FF0000, white; } .default-color1.chart-series-line { -fx-stroke: #00FF00, white; } .default-color2.chart-series-line { -fx-stroke: #0000FF, white; } .default-color0.chart-line-symbol { -fx-background-color: #FF0000, white; } .default-color1.chart-line-symbol { -fx-background-color: #00FF00, white; } .default-color2.chart-line-symbol { -fx-background-color: #0000FF, white; } But this is not enough for my purposes. I have three or more colored toggle buttons and a series of data for every button. The data should be displayed in the same color the button has after I have selected the button. This should be possible with a multiselection of the buttons, so that more than one series of data can be displayed simultaneously. For the chart lines I have managed it by changing the style after I clicked the button: .. dataList.add(series); .. series.getNode().setStyle("-fx-stroke: rgba(" + rgba + ")"); If I deselect the button I remove the data from the list. dataList.remove(series); That is working fine for the strokes, but how can I do the same for the legend? You can see an example below. First I clicked the red button, thus the stroke and the legend is red (default-color0). After that I clicked the blue button. Here you can see the problem. The stroke is blue but the legend is green, because default color1 is used and I do not know how to change the legend color.

  • How do I get the element after my horizontal css navigation bar to appear below it?

    - by Curyous
    I'm using a css unordered list to make a site navigation bar, using display: inline, display: block, and float: left. The next element that I put after the navigation bar is placed to the right of it. How can I align the next element so that it is displayed below? The html: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/html4/frameset.dtd"> <html> <head> <link type="text/css" rel="stylesheet" href="/stylesheets/test.css" /> </head> <body> <div> <ul class="nav"> <li class="nav"><a class="nav" href="#">One1</a></li> <li class="nav"><a class="nav" href="#">Two</a></li> <li class="nav"><a class="nav" href="#">Three</a></li> <li class="nav"><a class="nav" href="#">Four</a></li> </ul> </div> <div><h2>Heading</h2></div> </body> </html> The css: ul.nav, ul li.nav { display: inline; margin: 0px; padding: 0px; } ul.nav { list-style-type: none; } li.nav { display: block; float: left; background-color: red; } a.nav { background-color: green; padding: 10px; margin: 0px; } a:hover.nav { background-color: gray; }

  • Scrollbars in ScrollView not showing after custom child view changes size

    - by Ted Hopp
    I have a ScrollView containing a client that is a vertical LinearLayout. The client, in turn, contains custom views that change height dynamically as a background thread does some work. The problem I'm having is that the ScrollView's vertical scroll bar is not updating correctly in Android 1.5. The most common problem occurs when the initial total height of the client is less than the viewport and grows. Initially there is no scroll bar, and it does not show up when the client grows until I actually scroll the window with a touch gesture or other UI action. After that, the scroll bar shows up. However, the thumb does not update as the height continues to change from the background thread. If I scroll the view again through the UI, the thumb immediately corrects itself. My code for updating the height from the background thread is: post(mLayoutRequestor); postInvalidate(); (mLayoutRequestor is a Runnable that just calls requestLayout().) This is done after I've recorded the new height in a variable mHeight. My onMeasure() method calls setMeasuredDimension with a height computed like this: private int measureHeight(int measureSpec) { int result; int specMode = MeasureSpec.getMode(measureSpec); int specSize = MeasureSpec.getSize(measureSpec); if (specMode == MeasureSpec.EXACTLY) { result = specSize; } else { result = mHeight; if (specMode == MeasureSpec.AT_MOST && result > specSize) result = specSize; } return result; } Am I supposed to be calling something else besides requestLayout() to get the scroll bar to update correctly?

  • Vertically Aligning Elements

    I'm trying to understand how to center elements within a div. I have this basic code I am working with and am trying to get the 'This is a button' element to be in the center <body> <div style="width:960px;background-color:#d7d7d7;"> <div style=" width:400px; padding:10px; height:auto; background-color:#006699; display:inline-block; "> <p> Vivamus vel sapien.

  • CSS box around box technique

    - by webzide
    Dear Experts, I was trying to make an CSS division box with content in it as well as a border around it. Instead of using the box-border technique, I was trying out a new box to box technique instead. <html> <head> <style type="text/css"> #outer{ height: 20px; width: 20px; background-color:#233D78; } #inner{ height:18px; width: 18px; background-color: #FFF; font-size: 1em; text-align:center; font-family:'Bookman Old Style', serif; padding: 0px; margin-top: 1px; margin-right:auto; margin-left:auto; margin-bottom:1px; vertical-align:middle; } </style> </head> <body> <div id="outer"><div id="inner">TEXT</div></div> </body> </html> Somehow the borders are just not showing up right with FireFox. I tried everything. Setting up the Paddings of both boxes, margin, and messing around with the width. TO be honest, it took me around 30min to do this and I still can't get it right :( I know that a way to achieve the same result would be setting up a border around just one box. But I just wanna learn this box around box background-color technique. THanks in advance

  • Submit button not focused even though tabindex is properly set

    - by Nicsoft
    Hello, I have defined tabindex for the input fields in a form. When tabbing through the input fields the submit button is never getting the focus, some other input fields in a different form on the page gets the focus. Those are all having tabindexes higher than 3. How come? <form action="subscription.php" name="subscribe" method="post" onsubmit="return isValidEmailAndEqual()"> <p id="formlabel">E-mail</p> <input type="text" name="email1" tabindex=1> <br/> <p id="formlabel">Repeat e-mail</p> <input type="text" name="email2" tabindex=2> <br/> <input id="inputsubmit" type="submit" value="Subscribe" tabindex=3> </form> .css: input { background-color : #333; border: 1px solid #EEE; color: #EEE; margin-bottom: 6px; margin-top: 4px; padding: 1px; width : 200px; } #inputsubmit { background-color : #d7e6f1; border: 1px solid #EEE; color: #0000ff; margin-bottom: 6px; margin-top: 4px; padding: 1px; width : 200px; } #inputsubmit:hover { cursor: pointer; cursor: hand; background-color : #d7e6f1; border: 1px solid #0000ff; color: #0000ff; margin-bottom: 6px; margin-top: 4px; padding: 1px; width : 200px; } p#formlabel{ width: 100; } Thanks in advance!

  • CSS Layout-- Make table cell contents appear in row below and set height of parent row/cell

    - by Laramie
    I am modifying a skin for the CKEdit component so that the toolbar is hidden unless clicked. To do so, I moved the toolbar collapser to the row below it using position: relative and top:18px. My goal is to have the parent tr of the anchor element a height of 2px, but keep the anchor at 11px. Is this possible? I cannot alter the DOM, just the styles. Here's my reduced code <style type="text/css"> table { width: 80px;} td { border: solid 1px #ccc; } .header { background-color: #99f; /* This is being ignored */ height:2px; } .below { float: right; position: relative; top: 18px; /*If I shrink, the BG image goes Away*/ height: 11px; width: 11px; background-image: url('http://ckeditor.com/apps/ckeditor/3.3/skins/kama/images/sprites.png'); background-position: 4px -1387px; border: 1px outset #D3D3D3; } .hidden { display:none; } </style> <table> <tr><td class="header"><a class="below"><span class="hidden">#</span></a></td></tr> <tr><td>next row</td></tr> </table>

  • Adding jQuery event handler to expand div when a link is clicked

    - by hollyb
    I'm using a bit of jQuery to expand/hide some divs. I need to add an event handler so that when a link is clicked, it opens a corrisponding div. Each toggled div will have a unique class assigned to it. I am looking for some advice about how to build the event handler. The jQuery $(document).ready(function(){ $(".toggle_container:not(:first)").hide(); $(".toggle_container:first").show(); $("h6.trigger:first").addClass("active"); $("h6.trigger").click(function(){ $(this).toggleClass("active"); $(this).next(".toggle_container").slideToggle(300); }); The css: // uses a background image with an on (+) and off (-) state stacked on top of each other h6.trigger { background: url(buttonBG.gif) no-repeat;height: 46px;line-height: 46px;width: 300px;font-size: 2em;font-weight: normal;} h6.trigger a {color: #fff;text-decoration: none; display: block;} h6.active {background-position: left bottom;} .toggle_container { overflow: hidden; } .toggle_container .block {padding: 20px;} The html has a list of links, such as: <a href="#">One</a> <a href="#">Two</a> and the coorisponding divs to open: <h6 class="trigger">Container one</h6> <div class="toggle_container"> div one </div> <h6 class="trigger">Container two</h6> <div class="toggle_container Open"> div one </div> As I mentioned, I will be assigning a unique class to facilitate this. Any advice? Thanks! To clarify, i'm looking for some advice to build an event handler to toggle open a specific div when a link is clicked from a different part of the page, from a nav for instance.

  • Layout resize animation

  • JFrame that has multiple layers

    - by phunehehe
    Hello, I have a window that has two layers: a static background and a foreground that contains moving objects. My idea is to draw the background just once (because it's not going to change), so I make the changing panel transparent and add it on top of the static background. Here is the code for this: public static void main(String[] args) { JPanel changingPanel = new JPanel() { @Override public void paintComponent(Graphics g) { super.paintComponent(g); g.setColor(Color.RED); g.fillRect(100, 100, 100, 100); } }; changingPanel.setOpaque(false); JPanel staticPanel = new JPanel(); staticPanel.setBackground(Color.BLUE); staticPanel.setLayout(new BorderLayout()); staticPanel.add(changingPanel); JFrame frame = new JFrame(); frame.add(staticPanel); frame.setSize(800, 600); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setVisible(true); } This piece of code gives me the correct image I want, but every time I repaint changingPanel, staticPanel gets repainted as well (which is obviously against the whole idea of painting the static panel just once). Can somebody show me what's wrong? FYI I am using the javax.swing.Timer to recalculate and repaint the changing panel 24 times every second.

  • First test of a Windows Phone application

    - by Maurizio Reginelli
    I downloaded the Microsoft Visual Studio 2010 Express for Windows Phone and I wrote a simple application to make a first test of the emulator. In this application I have only a button with the property Content binded to a string called ButtonText and with the property Background binded to a SolidColorBrush named FillColor. I handled the Click event with this code: void MyButton_Click(object sender, RoutedEventArgs e) { if (toggle == true) { ButtonText = "Blue"; FillColor = new SolidColorBrush(Colors.Blue); } else { ButtonText = "Red"; FillColor = new SolidColorBrush(Colors.Red); } toggle = !toggle; } Unfortunately this doesn't work. While the Content of the Button changes each time the button is pressed, I cannot say the same for the Background which remains at the same color. Could you tell me what is wrong? Thank you. I also post the XAML: <Grid x:Name="ContentGrid" Grid.Row="1"> <Button Name="MyButton" Width="300" Height="300" Content="{Binding Path=ButtonText}" Background="{Binding Path=FillColor}" /> </Grid>

  • What Javascript graphing package will let me plot points against a user-selected coordinate system?

    - by wes
    My customer has some specific requirements for a graph to show in our web app. We use HighCharts elsewhere in the app for more traditional graphing, but it doesn't seem to work for this situation. Their requirements: Allow the user to select a background image, set the scale and origin of the coordinate system. We'll graph our points against the user-defined coordinates. Points can be color coded Mouse-over boxes show more detail about the points Support for zooming and panning, scaling the background appropriately Less importantly: Support for drawing vectors off the points Some of this seems basic, but looking around at different graph packages, I was unable to find any with an example of this kind of usage. I've entertained the thought of just hacking it together in canvas myself, but I've never worked with canvas before so I don't think it would be cost effective. The basics of plotting points with a scaled coordinate system against an image background wouldn't be too hard, but the mouse-over details, zooming and panning sound much more daunting to me. More info: Right now we use jQuery, HighCharts, and ExtJS for our app. We tried flot in the past but switched to HighCharts after flot didn't meet our needs.

  • Div on top of Div using z-index.

    - by Iacks
    I have the following divs in my HTML: <div class="main"> <div class="bgimage"></div> <div class="content">Text</div> which is directly inside my body. With the following CSS: .content{filter:alpha(opacity=50);-moz-opacity: 0.5;opacity: 0.5;} .content{position:relative;z-index:1;border:#000 thin solid;width:960px;margin-left:auto;margin-right:auto;background-color:#000;} .bgimage{position:absolute;z-index:-1;width:1024px;height:768px;margin-left:auto;margin-right:auto;background-image:url(bg1.jpg);} Basically, I have a Div that with a display of a background image, and I will have another Div on top of this with transparency. This current code works, but my problem is when I am trying to take the content div down from the top. When I add margin-top:100px, for example, is also brings the image down. I thought it would not touch it if it is not on the same z-index? Why does adding a margin also force the bgimage div down? I have also tried making the div with class of content a position of absolute and a zindex, but then this won't centre. How should I solve this?

  • grabbing layer contents in a class

    - by Mike
    I have a custom UIImageView class that creates thumbnails (UIImageView) and each thumbnail has a label. The label is created by another class. The label class creates a UIImageView and a UITextView on top of it. This is the init object class' init method: - (id)initWithFrame:(CGRect)frame { if ([super initWithFrame:frame] == nil) { return nil; } CGRect myFrame = CGRectMake(0, 0, 100, 100); myLabel = [[myLabelClass alloc] initWithFrame: myFrame]; //myLabelClass is a UIImageView based class [myLabel setCenter:CGPointMake(50, 50)]; [self addSubview: myLabel]; return self; } So, I have this MAIN VIEW CONTROLLER | |___ UIImageView WITH LABEL | |____ label background (UIView) |____ UITEXTVIEW (text) Now I want to write the contents of all these 3 components to a quartz context. I need to write using drawInRect, because I need to write the full object to a precise location. I expected object.layer.contents to be the image equivalent to these 3 "layers" flattened, in other words, the object's image, the label background and the label text, as it would if I created these 3 objects in Photoshop and flatten the composition. I also expect object.myLabel.layer.contents to contains the rendered contents of the UITextView over the label background. The problem is that when I use UIImage *myImage = [UIImage imageWithCGImage:objecto.myLabel.layer.contents]; [myImage drawInRect:CGRectMake(0, 0, 100, 100)]; I get nothing. How can I obtain a "flattened" image resultant to the full object (including its subviews)? thanks

  • How can I overlay images over one another in Java?

    - by Sam
    So I have been posting all over and have yet to get a solid answer: I have created an image resizing class, with a crop method. The cropping works great. The issue that I am having is the background color that I specify in the drawImage function of Graphics is not working correctly. It defaults to black as the background regardless of what I supply (in this case Color.WHITE). Also, the overlaying image or top most image (comes from a file) is being inverted (I think it is) or otherwise discolored. Just so you can conceptualize this a little bit better, I am taking a jpeg and overlaying it on top of a new BufferedImage, the new buffered image's background is not being set. Here is the code below that I am working with: public void Crop(int Height, int Width, int SourceX, int SourceY) throws Exception { //output height and width int OutputWidth = this.OutputImage.getWidth(); int OutputHeight = this.OutputImage.getHeight(); //create output streams ByteArrayOutputStream MyByteArrayOutputStream = new ByteArrayOutputStream(); MemoryCacheImageOutputStream MyMemoryCacheImageOutputStream = new MemoryCacheImageOutputStream(MyByteArrayOutputStream); //Create a new BufferedImage BufferedImage NewImage = new BufferedImage(Width, Height, BufferedImage.TYPE_INT_RGB); Graphics MyGraphics = NewImage.createGraphics(); MyGraphics.drawImage(this.OutputImage, -SourceX, -SourceY, OutputWidth, OutputHeight, Color.WHITE, null); // Get Writer and set compression Iterator MyIterator = ImageIO.getImageWritersByFormatName("png"); if (MyIterator.hasNext()) { //get image writer ImageWriter MyImageWriter = (ImageWriter)MyIterator.next(); //get params ImageWriteParam MyImageWriteParam = MyImageWriter.getDefaultWriteParam(); //set outputstream MyImageWriter.setOutput(MyMemoryCacheImageOutputStream); //create new ioimage IIOImage MyIIOImage = new IIOImage(NewImage, null, null); //write new image MyImageWriter.write(null, MyIIOImage, MyImageWriteParam); } //convert output stream back to inputstream ByteArrayInputStream MyByteArrayInputStream = new ByteArrayInputStream(MyByteArrayOutputStream.toByteArray()); MemoryCacheImageInputStream MyMemoryCacheImageInputStream = new MemoryCacheImageInputStream(MyByteArrayInputStream); //resassign as a buffered image this.OutputImage = ImageIO.read(MyMemoryCacheImageInputStream); }

  • Really cool way to create custom UITabBar for iPhone app?

    - by ludicco
    Hi, I am doing a lot of researching lately about how to get a different looking with nice effects UITabBar on my iPhone app, but unfortunately I am only finding things on how to replace background color etc. Well, I've checked out this app called Momento which is pretty cool and presents a very slick tabBar: So there are a couple of elements here I would like to ask you guys if you could help me by giving me the right directions on how to get a similar effect :) Arrow above items: as you can see this app has this animated arrow that runs above the selected item with a very smooth animation. Selected Stated of the item's image is not that blue-ish default one neither the default state which displays in a different shade of brown and gray version. nice Items separators with beveled vertical lines. diferrent background image for the tabBar different height for the tabBar At this point after some research I am able to set the height and background image by subclassing UITabBarController but I'm still not sure on how to accomplish the other items specially the first one related to the nice arrow effect. If someone knows about a very good tutorial on how to do this it would be great for clarifying what can or can't be done by subclassing the UITabBarController and specially if can be done in Interface Builder :) I am just starting on this world off app development for iOS so if you could help me on that it would be really appreciated Thanks a lot in advance

  • How can I set a Java applet transparency to show contents behind it?

    - by yuri
    I've got a web page with an applet inside. This applet is a drop target on a drag and drop action from the OS, I simply take an image from a folder, drag it on the applet and something happens. I give this webpage to a graphic designer and he ask to if he can put an image behind the java applet so he can simulate to change the background using CSS (it is a skinned app and graphic design can change during execution). Practically i supposed to do: <div> <applet width="50" height="50" /> </div> with this CSS: div { width:50px; height:50px; background-image: url(image.jpg) center center no-repeat; } But it doesn't work (background is opaque). It is possible to set transparency to the applet without loosing drag and drop capabilities ? I'm searching something similar to flash wmode parameter. Better solutions implies only changes on the CSS/HTML without recompiling java class so the designing team can change the page structure without changing the Java.

  • Where is the "ListViewItemPlaceholderBackgroundThemeBrush" located?

    - by Dimi Toulakis
    I have a problem understanding one style definition in Windows 8 metro apps. When you create a metro style application with VS, there is also a folder named Common created. Inside this folder there is file called StandardStyles.xaml Now the following snippet is from this file: <!-- Grid-appropriate 250 pixel square item template as seen in the GroupedItemsPage and ItemsPage --> <DataTemplate x:Key="Standard250x250ItemTemplate"> <Grid HorizontalAlignment="Left" Width="250" Height="250"> <Border Background="{StaticResource ListViewItemPlaceholderBackgroundThemeBrush}"> <Image Source="{Binding Image}" Stretch="UniformToFill"/> </Border> <StackPanel VerticalAlignment="Bottom" Background="{StaticResource ListViewItemOverlayBackgroundThemeBrush}"> <TextBlock Text="{Binding Title}" Foreground="{StaticResource ListViewItemOverlayForegroundThemeBrush}" Style="{StaticResource TitleTextStyle}" Height="60" Margin="15,0,15,0"/> <TextBlock Text="{Binding Subtitle}" Foreground="{StaticResource ListViewItemOverlaySecondaryForegroundThemeBrush}" Style="{StaticResource CaptionTextStyle}" TextWrapping="NoWrap" Margin="15,0,15,10"/> </StackPanel> </Grid> </DataTemplate> What I do not understand here is the static resource definition, e.g. for the Border Background="{StaticResource ListViewItemPlaceholderBackgroundThemeBrush}" It is not about how you work with templates and binding and resources. Where is this ListViewItemPlaceholderBackgroundThemeBrush located? Many thanks for your help. Dimi

  • http authentication fails in cucumber when adding @javascript tag

    - by JESii
    I have a feature in my Rials app that works just fine with the message "Responds to browser_basic_authorize" from the Background Given step. However, if I add a @javascript tag before the scenario, then my Background Given fails with "I don't know how to login". What's going wrong and how do I go about testing javascrpt interactions on my app? Background: Given I perform HTTP authentication as "<id>/<password>" When I go to the homepage Then I should see "Text-that-you-should-see-on-your-home-page" Scenario: Displaying injury causative factors Given I am on the new_incident_report page When I choose "incident_report_employee_following_procedures_true" Then I should see "Equipment failure?" Then I should not see "Lack of training" When /^I perform HTTP authentication as "([^\"]*)\/([^\"]*)"$/ do |username, password| puts "id/pswd: #{username}/#{password}" ### Following works ONLY if performed first before even going to a page!!! if page.driver.respond_to?(:basic_auth) puts 'Responds to basic_auth' page.driver.basic_auth(username, password) elsif page.driver.respond_to?(:basic_authorize) puts 'Responds to basic_authorize' page.driver.basic_authorize(username, password) elsif page.driver.respond_to?(:browser) && page.driver.browser.respond_to?(:basic_authorize) puts 'Responds to browser_basic_authorize' page.driver.browser.basic_authorize(username, password) else raise "I don't know how to log in!" end end Rails 3.0.9, current gems, other tests passing.
