custom-controls

I'm trying to make a trackbar with a custom graphic for the slider thumb. I have started out with the following code: namespace testapp { partial class MyTrackBar : System.Windows.Forms.TrackBar { public MyTrackBar() { InitializeComponent(); } protected override void OnPaint(System.Windows.Forms.PaintEventArgs e) { // base.OnPaint(e); e.Graphics.FillRectangle(System.Drawing.Brushes.DarkSalmon, ClientRectangle); } } } But it never calls OnPaint. Anyone else come across this? I have used this technique before to create an ownerdraw button but for some reason it doesn't work with TrackBar. PS.

I am trying to make a custom control with JavaFX and SceneBuilder 1.1. I have this code: FXML <?import libreria.javaFX.componentes.componenteTextField.*?> <AnchorPane id="AnchorPane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns:fx="http://javafx.com/fxml"> <children> <CustomComponent fx:id="pastaTxt" layoutX="69.0" layoutY="87.0" prefWidth="200.0" /> </children> </AnchorPane> CustomComponent.java package libreria.javaFX.componentes.componenteTextField; import javafx.scene.control.TextField; public class

I followed the posts and was able to change the stars for the custom RatingBar, but in doing this I was no longer able to set the value to be a decimal lower than a half (e.g. 0.2). It would always show up as the half (e.g. 0.5). When I set the value to be above the half (e.g. 0.7) it displays perfectly.

In visual studio when you create a custom control you get this ugly little purple gear thing for an icon of your control instead of a custom control . So how can I change the icon for my control? Simon Broadhead Use the ToolboxBitmap attribute on the class. Put your icon (for exemple "icon.bmp" 16x16 pixels) on the root folder of your custom control project Include this line just before your control class : [ToolboxBitmap(typeof(yourControl), "yourControl.bmp")] Here are further steps you need to take care of:- Verify your bitmap has the following properties : Height of 16 pixel Width of 16

I want to make a custom button control (image button is ok) like this one. I'm a new user, so I can't post image here. So I uploaded the picture here I'm kind of desperate right now after trying some tutorials Any suggestion is highly appreciated. Thanks You could create a class that inherits from Button to keep all your styling in one place. To do the hover and pressed states you can override the mouse enter / leave events of the button and change style. Here is an example from one of our projects (I changed the colours but your get the idea). Where we change some colours you could switch the

So I use Java Swing to build the UI for my app and use custom images to replace the ugly Java ones, the custom images have a style and are very easy to integrate into Java Swing. Right now my problem is I need to use a JScrollBar with a JScrollPane in an app and I really don't want to use either the default Java Scroll Bar or even the native OS Scroll Bar. I just want to be able to have a custom image be the Background of the scroll bar and an image to be the Thumb of the scroll bar. How to make a custom JScrollBar using an image? I wrote an example that shows how to set a custom image for the
