  • Change color of CheckboxColumn if checked

    - by user896692
    Searched a lot about this problem but never found a answer, that solved it. I´ve got the following CheckboxColumn in a WPF datagrid: <DataGridCheckBoxColumn Header="Erledigt" Binding="{Binding Path=erledigt}" /> The variable erledigt contains 0 or 1. Now I want, that if the Checkbox is checked, the cellbackground is green. Hopelessly searched for a checked property. How can I manage this?

  • Is it possible to seletively color a label in Silverlight

    - by joemoe
    For instance, if I have a label: Blah blah bladity blah I want the first 10% of this label, such that the font color should be red, and the rest should be green. This perhaps means it would color the Bl and PART of the a. Basically pixel-wise font coloring instead of character-wise. Is this possible and how would is be accomplished?

  • What's the best way to structure this Linq-to-Events Drag & Drop code?

    - by Rob Fonseca-Ensor
    I am trying to handle a drag & drop interaction, which involves mouse down, mouse move, and mouse up. Here is a simplified repro of my solution that: on mouse down, creates an ellipse and adds it to a canvas on mouse move, repositions the ellipse to follow the mouse on mouse up, changes the colour of the canvas so that it's obvious which one you're dragging. var mouseDown = Observable.FromEvent<MouseButtonEventArgs>(canvas, "MouseLeftButtonDown"); var mouseUp = Observable.FromEvent<MouseButtonEventArgs>(canvas, "MouseLeftButtonUp"); var mouseMove = Observable.FromEvent<MouseEventArgs>(canvas, "MouseMove"); Ellipse ellipse = null; var q = from start in mouseDown.Do(x => { // handle mousedown by creating a red ellipse, // adding it to the canvas at the right position ellipse = new Ellipse() { Width = 10, Height = 10, Fill = Brushes.Red }; Point position = x.EventArgs.GetPosition(canvas); Canvas.SetLeft(ellipse, position.X); Canvas.SetTop(ellipse, position.Y); canvas.Children.Add(ellipse); }) from delta in mouseMove.Until(mouseUp.Do(x => { // handle mouse up by making the ellipse green ellipse.Fill = Brushes.Green; })) select delta; q.Subscribe(x => { // handle mouse move by repositioning ellipse Point position = x.EventArgs.GetPosition(canvas); Canvas.SetLeft(ellipse, position.X); Canvas.SetTop(ellipse, position.Y); }); the XAML is simply <Canvas x:Name="canvas"/> There's a few things I don't like about this code, and I need help refactoring it :) First of all: the mousedown and mouseup callbacks are specified as side effects. If two subscriptions are made to q, they will happen twice. Second, the mouseup callback is specified before the mousemove callback. This makes it a bit hard to read. Thirdly, the reference to the ellipse seems to be in a silly place. If there's two subscriptions, that variable reference will get overwritten quite quickly. I'm sure that there should be some way we can leverage the let keyword to introduce a variable to the linq expression that will mean the correct ellipse reference is available to both the mouse move and mouse up handlers How would you write this code?

  • Avoid hardcoding iPhone screen size with programmatic view creation

    - by miorel
    Hi, I was looking up how to create a view programmatically and found the following example code: self.view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; This works great, except I don't like that it hardcodes the size of the screen. Is there a way to look up the size of the screen? An important point someone brought up is that if the app is running during a phone call then the screen will be slightly smaller because of the green "return to call" bar.

  • Effects of changing a node in a binary tree

    - by eSKay
    Suppose I want to change the orange node in the following tree. So, the only other change I'll need to make is in the left pointer of the green node. The blue node will remain the same. Am I wrong somewhere? Because according to this article (that explains zippers), even the blue node needs to be changed. Similarly, in this picture (recolored) from the same article, why do we change the orange nodes at all (when we change x)?

  • Generate random coordinates from area outside of a rectangle?

    - by Rockmaninoff
    Hi all, I'm working on a simple tutorial, and I'd like to randomly generate the positions of the red and green boxes in the accompanying images anywhere inside the dark gray area, but not in the white area. Are there any particularly elegant algorithms to do this? There are some hackish ideas I have that are really simple (continue to generate while the coordinates are not outside the inside rectangle, etc.), but I was wondering if anyone had come up with some neat solutions. Thanks for any help!

  • Z-Index and javascript for rollover

    - by Raffaele
    I have a container (div) with a background image. In this div there is a menu - a horizontal list. What I need is to insert an image onMouseOver, positioning it absolutely, and showing it behind the text (of course!) AND on top of the div's background image. I also use jQuery, but I think this doesn't matter. The problem can be viewed online. Go to http://www.w3schools.com/css/tryit.asp?filename=trycss_zindex and paste the following text <html> <head> <style type="text/css"> img { top: 0; left: 0; position:absolute; z-index:-1; } #main { color: red; margin: 30px; padding: 20px; width: 700px; min-height: 400px; z-index: -2; background-image: url("http://www.google.com/logos/mother10-hp.gif"); background-repeat: no-repeat; } </style> </head> <body> <div id="main"> <h1>Z-Index question:</h1> <img src="w3css.gif" width="100" height="140" /> <p>How can we place the green pic between the text and the div#main?</p> <p>I need the green gif to appear</p> <ol> <li>On top of #main's background image</li> <li>Behind the text</li> </ol> </div> </body> </html>

  • Silverlight: Set Items Widths in ItemsControl to Stretch

    - by Tom Allen
    I've got an ItemsControl which fills from top to bottom, but I can't get it's child items to occupy the whole width of the ItemsControl: I basically need to stretch the green bits to fill the width of the control (as shown by the blue bits). I've tried things like setting the HorizontalAlignment property of the template item to Stretch and I've even tried binding it's Width property to the ItemsControl Width, but neither worked. Should be a straight forward one, but it's something I just can't quite figure out...

  • Hide button on first of two UIViews, but have it visible on second...

    - by Scott
    So I have a UIViewController (main application controller is a TabBarController). On this there is a UINavigationBar, and a UIBarButtonItem. I'm PRETTY sure I hooked up everything correctly in the Interface Builder and that the outlet in the code is connected to the button in the .xib. It should be because the method works correctly. Now I have another button on this view that brings up a second view, a UIWebView. I want this UIBarButtonItem, labeled "Back", to make the UIWebView dissapear, and bring back the first UIView, which it DOES DO correctly. However, when you are on the first UIView, there is no need to see the UIBarButtonItem, so how can I hide it but then bring it up for the UIWebView. By the way, both views use the same UINavigationBar, the UIWebView is brought up inside the tab bar and the nav bar. Here is my code: #import "WebViewController.h" @implementation WebViewController @synthesize webButton; @synthesize item; @synthesize infoView; UIWebView *webView; + (UIColor*)myColor1 { return [UIColor colorWithRed:0.0f/255.0f green:76.0f/255.0f blue:29.0f/255.0f alpha:1.0f]; } // Creates Nav Bar with default Green at top of screen with given String as title + (UINavigationBar*)myNavBar1: (NSString*)input { UIView *test = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0.0, 0.0, test.bounds.size.width, 45)]; navBar.tintColor = [WebViewController myColor1]; UINavigationItem *navItem; navItem = [UINavigationItem alloc]; navItem.title = input; [navBar pushNavigationItem:navItem animated:false]; return navBar; } - (IBAction) pushWebButton { self.navigationItem.rightBarButtonItem = item; CGRect webFrame = CGRectMake(0.0, 45.0, 320.0, 365.0); webView = [[UIWebView alloc] initWithFrame:webFrame]; [webView setBackgroundColor:[UIColor whiteColor]]; NSString *urlAddress = @"http://www.independencenavigator.com"; NSURL *url = [NSURL URLWithString:urlAddress]; NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; webView.scalesPageToFit = YES; [webView loadRequest:requestObj]; [self.view addSubview:webView]; [webView release]; } - (void) pushBackButton { [webView removeFromSuperview]; } // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { self.navigationItem.rightBarButtonItem = nil; [super viewDidLoad]; } @end Anyone know?

  • Creating a ListView and setting the background color of a view in each row.

    - by Tarmon
    Hey Everyone, I am trying to implement a ListView that is composed of rows that contain a View on the left followed by a TextView to the right of that. I want to be able to change the background color of the first View based on it's position in the ListView. Below is what I have at this point but it doesn't seem to due anything. public class Routes extends ListActivity { String[] ROUTES; TextView selection; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ROUTES = getResources().getStringArray(R.array.routes); setContentView(R.layout.routes); setListAdapter(new IconicAdapter()); selection=(TextView)findViewById(R.id.selection); } public void onListItemClick(ListView parent, View v, int position, long id) { selection.setText(ROUTES[position]); } class IconicAdapter extends ArrayAdapter<String> { IconicAdapter() { super(Routes.this, R.layout.row, R.id.label, ROUTES); } } public View getView(int position, View convertView, ViewGroup parent) { LayoutInflater inflater = getLayoutInflater(); View row = inflater.inflate(R.layout.row, parent, false); TextView label = (TextView) row.findViewById(R.id.label); label.setText(ROUTES[position]); View icon = (View) row.findViewById(R.id.icon); switch(position){ case 0: icon.setBackgroundColor(R.color.Red); break; case 1: icon.setBackgroundColor(R.color.Red); break; case 2: icon.setBackgroundColor(R.color.Green); break; case 3: icon.setBackgroundColor(R.color.Green); break; case 4: icon.setBackgroundColor(R.color.Blue); break; case 5: icon.setBackgroundColor(R.color.Blue); break; } return(row); } } Any input is appreciated and if you have any questions don't hesitate to ask!

  • Android Drawable question.

    Hey Everyone, I am trying to create a drawable in code and change the color based on some criteria. I can get it to work but it doesn't want to let me set the padding on the view.
