[platform-swt-dev] Tri-state Checkbox

[Thomas Singer <ts-swt@xxxxxxxxxxx>]

Hi,

It looks like a checkbox can work in 2 different modes, either toggling 
between selected and unselected, and toggling between tri-state and 
unselected. So my understanding it that to set it programmatically to 
the tri-state mode, I have to invoke

  checkbox.setGrayed(true);
  checkbox.setSelection(true);

How can I make it switch between selected - unselected - tri-state using 
the mouse? Or should I simulate it myself using mouse-click-listeners?
