[pygtk] refs and reparent ...
I have a problem with pygtk (great works which gets more and more attention !)(which it deserves) i have two treeitems in a tree. I connect those iteme to signal select, unselect, get_target_getdata and drag_source_givedata, and declare them as drag_source and drag_target (i don't remember the signals but the idea is here). i would like to go from : -A -B to -A + B. originally, they display and drags right, but when i try to reparent the second item to a subtree of the first item, or try to do itemB["parent"].remove(item),(to create a new B as a subtree of A) then the application segfaults. From C gtk programs' sources, people usually ref() the object and then reparent it. I haven't seen any ref() method to gtkobject (and i assume this is right as python takes care of ref counting), but if i try to disconnect all signals and try to unset dragsources all, this doen't work either. I'll try to have a simple program that segfaults unconditionnally to be more explicit. I have gtk 1.2.8 and pygtk 0.6.6 Are this kind of problem known issues, resolved with the extensionclass way in 0.7 ? thanks in advance for any useful input, I'll try to be more explicit, but this really drives me crazy ! xavier ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk

Can't even add buttons or labels this way. Is this due to the use of libglade? It seemed to work in PyGTK proper. This should work. If you have some container widget in the glade file you should be able to add a GtkXmHTML widget. You did show() the XmHTML widget, didn't you? Ah, show() was the magic method that makes it all work. Thanks! I didn't run into this in the many documents I perused last night for some reason..must've been looking in the wrong places. Given my one day experience with GTK programming I hope you'll forgive my ignorance. :) It speaks for PyGTK, Glade, libglade and python that I was already trying to integrate a HTML widget after a day. Thanks again, also for the quick response! Regards, Martijn ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk
[pygtk] PyGTK and urllib
Hi there, I've run into an odd problem with urllib.urlopen() apparently taking a *lot* more time when used through PyGTK (using LibGlade and Gnome) than when I call the same routine through python only. In fact, if I call urlopen() through the Gnome interface, *everything* in X seems to become unresponsive; the only thing I can move around is the mouse cursor, but since I can't click anything, it's not very useful. Oddly enough in the same app I call urlopen() somewhere else that doesn't cause this kind of blocking. But I did whittle down my code and it *does* seem to be urlopen() in the second case. Anyone have any suggestions? Regards, Martijn ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk

Anyone have any suggestions? Unless I am mistaken, urllib is a syncronous interface, so it will not return until it has completed the transfer. This means your application will not process any events (mouse clicks, expose events, etc) until the transfer completes, which is what is causing your problems. You should either use an asyncronous transfer (using the input_add() function to set up a handler for when information comes in on the socket), or look at using threads.
