threading problem with TableTreeViewer.refresh() [message #439119]

Hi,

I wondering in what thread should i call TableTreeViewer.refresh().

Following the source code, the refresh() eventually calls the following
method in Widget class to do the thread checking. If the thread that calls
refresh() is the correct thread, it issues invalid access error.

protected void checkWidget () {
Display display = this.display;
....
if (display.thread != Thread.currentThread ()) error
(SWT.ERROR_THREAD_INVALID_ACCESS);
....
}

I am implementing a listener and want to call TableTreeViewer.refresh() when
something changes in my model. What's the correct way to make such a call?

Thanks a million.

This means you are calling from some thread other then the display
thread. If you are not on the display thread, you need to use
Display.asyncExec() or Display.syncExec() to get the refresh() to be
called on the display thread.
