I have a Gtk# application where the processing of a menu item may take
many seconds. I want to change the cursor to a Watch before the actual
processing takes place, and then change the cursor back to Arrow when
done. For example:
OnMenuItem(...)
{
DoSetupProcessing();
this.GdkWindow.Cursor = new Gdk.Cursor(Gdk.CursorType.Watch);
DoLongProcessing();
this.GdkWindow.Cursor = new Gdk.Cursor(Gdk.CursorType.Arrow);
}
With this code the watch cursor is never displayed because UI updating
normally only occurs during idle processing, which of course does not
occur until after OnMenuItem returns.
Is there a way to force the update to display the watch cursor without
DoLongProcessing using a separate thread?
Jim
