Gentle People:
I have a rather large project in progress based on the GTK2/Cairo
packages.
Which brings me to the following question about gtk_widget_queue_draw:
For each Menu Function, meaning a C function, which is called by a menu
event handle,
in response to a Menu Selection. I place a gtk_widget_queue_draw at the
end of the function
to cause the screen to update in response to the command. Learned
behavior from examples
and experience. This seems to work great.
Now the question: If the menu function is complex, requiring seconds or
minutes to execute
the screen freezes or if windows are moved fails to update and we are
left with a default
grey screen. Is there any way to cause a queue draw and screen up date
from within this
long latency function.
My experience indicates that calling gtk_widget_queue_draw from within
this long latency
function dose not cause a screen update.
