Introduction
This widget is a Push or Toogle Button with and attached menu. When the user clicks on the left part of the button, the action (push or toggle) is performed. Otherwise, a menu is displayed
Contents
Usage
There is three steps : First, you instantiate a SplitButton object :
final SplitButton actionButton = new SplitButton(shell, SWT.NONE);
The style can be SWT.NONE or SWT.PUSH to create an instance of a Push button, or SWT.TOGGLE for a Toggle button.
Then you get the menu associated to this button :
final Menu actionMenu = actionButton.getMenu();
And you add the items associated to this menu :
final MenuItem item = new MenuItem(actionMenu, SWT.PUSH);
item.setText("First menu item");
item.addListener(SWT.Selection, e -> System.out.println("Click on menu item 'First menu item'"));
And voilà, it is done !
The SolitButton API mimics the Button API. You can add selection listeners, change button state...
