Hello,
Is there a way to move the event loop around?
I just want to check some widget events in a
looong processing loop but the routine
event = widget_event(hiddenTextID,/nowait)
always returns with event structure {0, 0, 0}
The strange thing is that if I don't care about
this but fill in the fields myself then the program
works as intended. There are actually sensible events
like keyboard hits getting through somehow.
event = widget_event(hiddenTextID,/nowait)
; Fill in event.top that was 0 with something
; that xmanager would give me
event.top = self.tlb
widget_control, event.top, set_uvalue=self
; Call the main event handler directly
rawgui_events, event
; This works like a dream but clutters up the heap
What I would like to do is to stop event processing in
xmanager while I run my long loop and process events
one at a time. Can this be done easily?
I run this in pure object-graphics so it is slightly
different from the TestKey-example in Davids treasure
chest.
