custom-controls

I want to have a UIElement (any of UIView, UIButton, UILabel etc.) with custom shape lets say a triangle. How do you suggest to achieve it. Thanks in advance. Here is a sample of a UIView subclass (triangle): @implementation TriangleView - (id)initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; if (self) { // Initialization code } return self; } - (void)drawRect:(CGRect)rect { // Drawing code CGContextRef ctx = UIGraphicsGetCurrentContext(); CGContextBeginPath(ctx); CGContextMoveToPoint (ctx, CGRectGetMinX(rect), CGRectGetMaxY(rect)); // top left CGContextAddLineToPoint(ctx,

I'm trying to create a GUI (WPF) Library where each (custom) control basically wraps an internal (third party) control. Then, I'm manually exposing each property (not all of them, but almost). In XAML the resulting control is pretty straightforward: <my:CustomButton Content="ClickMe" /> And the code behind is quite simple as well: public class CustomButton : Control { private MyThirdPartyButton _button = null; static CustomButton() { DefaultStyleKeyProperty.OverrideMetadata(typeof(CustomButton), new FrameworkPropertyMetadata(typeof(CustomButton))); } public CustomButton() { _button = new

During an interview, the company was asking about my use of custom controls in WPF. I have found with all of the power of the WPF way of creating a control (datatemplate, control template, styles,triggers etc... ) that having to write a custom control that overrides the OnRender method really hasn't been necessary. Later found out that most of their development has been in Winforms. If coming at a control from a 100% WPF direction, how often is it necessary to write a customcontrol with OnRender overrides? The Winform approach is really not making use of the WPF composition technique of

I've a drawable for some items like buttons, checkboxes, progress bars and I'd like to define those drawables for beeing the default style of all the buttons my app uses. Is that possible without declaring the style in each View individually? If the answer is to use a Theme for the app I'd appreciate an example (changing the style of all the buttons for example) because I don't understand how to define it. Thanks in advance The answer is to use a theme as you were expecting. Good documentation can be found on android developer site: http://developer.android.com/guide/topics/ui/themes.html For

I need to put an image in the default view of a custom control. However, whenever I try to test the control it can't locate the image. I have tried to compile it as an embedded resource and just a plain resource in VS. Neither of these have worked. So is there a correct way to do this? Sergey Aldoukhov Look at this post: How can I get a BitmapImage from a Resource? That's probably because you specified the image path as a relative path. You should use the Pack URI Scheme to specify that the resource is in the current assembly. For instance : <Image Source="pack://application:,,,/Images/MyImage

I believe am in need of creating custom RichTextBox in C#. One kind of like that: I admit it might not even have to be RichTextBox , but after some research I decided it's gonna be the easiest way. Functionality I need are icons at each row, checkboxes and text formatting. My program will process each line of the text and mark lines that are correct, incorrect, and strike out lines not necessary in further work, while showing line that's currently processed and allowing user to edit some lines freely (here: lines before Around 3 000 won't be editable, but those under the line will). What's the
