ColorButton

Introduction

Methods

• setRGB(RGB) set the initial color value.
• getRGB() gets the selected color or the initial color, when no color selected.
• chooseRGB(IColorChooserFactory) for use inside a SelectionListener.
• setColorChooserFactory(IColorChooserFactory) sets a factory for creating color choosers.
• setResultConsumer(Consumer) sets a consumer for the selected color.
• You can also use all SWT Button methods.

Color choosers

• ColorChooserHSB, selects a color by hue, brightness and saturation.
• ColorChooserRGB, selects a color by red, green, blue.
• ColorWheelChooser, selects a color from a color wheel.
• ColorPicker, selects a color from a predefined or user defined color list.

Example: Use a Listener or SelectionListener

...
final ColorButton colorButton = new ColorButton(parent);
colorButton.setText("Click me!");

// initialize with current background rgb
colorButton.setRGB(shell.getBackground().getRGB());

colorButton.addListener(SWT.Selection, e -> {
	final RGB rgb = colorButton.chooseRGB(p -> new ColorChooserHSB(p, ColorResolution.Medium, true));
	// check if new color selected
	if (rgb != null) {
		// enter your own code here
	}
});
...

Example: ColorButton without Listeners

...
final ColorButton colorButton = new ColorButton(parent);
colorButton.setText("Click me!");

// initialize with current background rgb
colorButton.setRGB(shell.getBackground().getRGB());

colorButton.setColorChooserFactory(p -> new ColorWheelChooser(p, ColorResolution.Minimal, false));
colorButton.setColorConsumer(rgb -> {
	// enter your own code here
});
