Hi Ulrik,

When handling the respective shellClosed event just set the doIt flag of
the
ShellEvent which was handed over to false. This will prevent the close
operation from being executed. In other words the close operation is
cancelled. 

Best regards

Subject: [platform-swt-dev] Prevent Shell from closing/disposing

Hello List,

I currently face a problem which I couldn't solve by googling.

I want to open a Dialog when the toplevel Shell is closed via the 
close-button in the titlebar. The dialog should ask the user wether he
really wants to quit (due to unsaved data).

The problem I have: I don't know how to "stop" the closing of
the Shell. 
I both tried the Dialog in the disposeListener and the shellListener in
shellClosed, but in both cases, I don't know what to do if the user 
klicks "Cancel", I don't know how to stop the shell from closing/disposing.

Any help is greatly appreciated!

best regards and please excuse my bad english as it is not my native 
language

Ulrik
