Hi,
I'd like to ask you for help with solving my problem. First I'll try to
describe what I'm doing:
I have a PyGTK application which needs to run an external command. I use
subprocess.Popen to do it. Then I run a gtk.Dialog (saying "Please
wait") and wait until the process is finished. After the external
process finishes I close the dialog and the program continues. So far
everything works fine. But now I want to change it a little. After the
process is finished, I want to return to the main loop but keep the
dialog opened. Then process results of the external program and run the
external program again. Repeat this a couple times and then finally
close the "Please wait" dialog.
I found out that I can return back while leaving the dialog opened by
calling dialog.return(0). But when I run the dialog again with
dialog.run(), Python (the interpreter) crashes. What is the problem? Is
it impossible to run the same dialog twice? What else could I do?
I need to block the main program loop because it can't continue before
the external program finishes. At the same time I want to have a pop up
window with a "Cancel" button (the window must be responsive). I'm
afraid I'm not experienced enough to use threading, which would be
probably best suited for this task. What would be the most simple way to
solve my problem?
I hope it is clear what I'm trying to do. Unfortunately my English is
far away from being perfect. If a code sample would help, I can post it.
Best regards,
Vlada
