GanttChart - Custom Context Menu [message #1058244]

Hi,

via showMenuItemsOnRightClick from the (Abstract)Settings I can enable/disable the context menu in the gant chart which shows menu items for zoom and so on. Now I want to add custom menu items.

ganttChart = new GanttChart(parent,SWT.MULTI,createSettings(),null,null,createLanguageManager());

ganttChart.getMenu() is only null. How can I add own Items to the context menu.

Thanks

Alex

I know this is an old topic but since I haven't found a solution to this problem in the forums i guess it would be ok to post my findings on how to add custom menu items to the context menu.

The solution is rather simple you just have to overwrite the getMenu() method in the GanttEvent. You then just return a menu with the items that you want to add to the context menu.
Here is an example of how this can be done:

class CustomGanttEvent extends GanttEvent
{
	@Override
	public Menu getMenu()
	{
		//Create the menu
		final Menu menu = new Menu( getParentComposite() );
		//Create the menu items you want to add
		final MenuItem menuItem = new MenuItem( menu, SWT.PUSH )
		return menu;
	}
}
