RE: [platform-swt-dev] AsyncExec() problem ?
|
yes this is exactly the pb :
the runnable has always the focus. and it never share it with the GUI.
so that when I use a loop-runnable to update the GUI, I lose totally the
focus of the GUI.

If I understand things correctly, this Runnable will hijack the GUI
thread. That would be why the GUI wouldn't respond. I'm not sure what
that has to do with the processing of this thread.
If you had:
//set a thread to update the gui.
display.asyncExec( new Runnable() {
public void run() {
while(true) {
System.out.println("aa");
//here, stuff to update the gui.
}
}
});
while(true) {
System.out.println("bb");
}
I would expect to see both "aa" and "bb" on the console, but the GUI
would never refresh. Is that what you get when you run it?
Apologies if I didn't understand your question correctly, I'm just
responding to the code presented.
