Introduction

Switchbutton.jpg

This is a switch button to pick one value.

Usage

A switch button is a different graphic representation of a checkbox button. So the API is similar to the Button widget. You can get or set the selection,add selection listeners, enable or disable the button...

final SwitchButton button = new SwitchButton(shell, SWT.NONE);
button.setText("Switch button...");
button.setTextForSelect("Selected...");
button.setTextForUnselect("Unselected...");
button.addSelectionListener(new SelectionListener() {

	@Override
	public void widgetSelected(final SelectionEvent e) {
		System.out.println("Before clicking, the selection was... " + button.getSelection());
	}

	@Override
	public void widgetDefaultSelected(final SelectionEvent e) {
	}
});

Customisation

By default, the button is grey, without border, with a blue background and 2 labels "On" and "Off". You can customize almost all elements of a switch button by setting the following properties :

  • textForSelect: text associated to the selected state of the button
  • textForUnselect: text associated to the unselected state of the button
  • text: text displayed besides the button
  • round: if true, the switch button's corners are round. If false, the switch button's corners are square.
  • borderColor: if set, a border is displayed around the widget.
  • focusColor: Color of the button when the focus is on.
  • selectedForegroundColor and selectedBackgroundColor: Color of the button (text color and background color) of the selected state of the button.
  • unselectedForegroundColor and <code>unselectedBackgroundColor: : text associated to the select state of the button
  • buttonBorderColor, buttonBackgroundColor1 and buttonBackgroundColor1: Colors of the button (border and gradient)
  • gap: gap between the button and the associated text
  • foreground, background: foreground and background colors of the whole widget.
  • font: font of the widget
