Hi,

I'm experiencing the same "error/strange behaviour" as was mentioned in
the unresponded post "[SWT][Thread] Strange Exception" posted on
13/12/2002 19.18 in this NG.

In my environment there is a diff. Yhe same code works on w2k and causes
the mentioned error only on MAX OSX 10.2

Is somebody out there who has seen this problem and got rid of it
(without switching to swing ;-) )


Frank

This exception is thrown because you try to modify a GUI elment outside a
GUI thread.

To handle this problem use this:

Display display = Display.getCurrent();
if (display==null) display = Display.getDefault();

display.asyncExec( new Runnable(){

public void run(){
// Put your GUI modif. here.
}

});


Note that you could replace the asyncExec() by a syncExec()
