Introduction

A widget used to launch applications, modules or anything, with a simple and fancy zoom effect, widely inspired by work of Romain Guy.

Usage

This launcher contains 4 methods :

• 2 methods to add and remove selection listeners (addSelectionListener and removeSelectionListener)
• One method to add and item : void addItem(final String title, final String image) where title is the text located under the image
• A method to get the selected item : int getSelection()

 final Launcher l = new Launcher(shell, SWT.NONE);
 l.setLayoutData(new GridData(GridData.FILL, GridData.FILL, true, true));
 l.addItem("Address Book", "org/mihalis/opal/launcher/icons/x-office-address-book.png");
 l.addItem("Calendar", "org/mihalis/opal/launcher/icons/x-office-calendar.png");
 l.addItem("Presentation", "org/mihalis/opal/launcher/icons/x-office-presentation.png");
 l.addItem("Spreadsheet", "org/mihalis/opal/launcher/icons/x-office-spreadsheet.png");

l.addSelectionListener(new SelectionAdapter() {

	/**
	 * @see org.eclipse.swt.events.SelectionAdapter#widgetSelected(org.eclipse.swt.events.SelectionEvent)
	 */
	@Override
	public void widgetSelected(final SelectionEvent e) {
		Dialog.inform("Selection", "You have selected item #" + l.getSelection());
	}

});
