[pygtk] Segfault with popup menus
With this program:
from gtk import *
def button_press(widget, event):
if event.button == 3:
menu = GtkMenu()
menu.append(GtkMenuItem('foo'))
menu.append(GtkMenuItem('bar'))
menu.popup(widget, None, None, event.button, event.time)
window = GtkWindow(WINDOW_TOPLEVEL)
window.connect('destroy', mainquit)
button = GtkButton('foo')
button.connect('button-press-event', button_press)
window.add(button)
button.show()
window.show()
mainloop()
I run the program, then right-click on the button, and I get this:
[pbrannan@zaphod python]$ python test.py
Segmentation fault (core dumped)
Looking at this in gdb, I see:
Program received signal SIGSEGV, Segmentation fault.

I have no idea what's causing self=0x0, but I suspect that's why the
program is segfaulting.
A couple of questions:
1) Is there an easier way to get a popup menu?
2) How can I rewrite the above code to not segfault?
Thanks,
Paul

Re: [pygtk] Segfault with popup menus
Paul,
Pass in None instead of widget as the first arg to menu.popup. Also need to
have the menu displayed. Changes below.

Re: [pygtk] GtkTree examples?
Thanks for the pointers. I haven't tried it out yet but it looks like it'll do the trick.

[pygtk] Greetings!
Greetings! I'm a Python/pygtk newbie, looking for documentation (or outright help ::grin::). I'm working on a program where I'd like to be able to swap window-widget sub-sets around with other pre-defined widget sub-sets, if this is possible. I'm not sure how to explain exactly what I'm trying to do, so I'll spew out a quick example. Starting with the window pictured at http://linus.smenet.org/~ballbee/pygtklist/main_window.gif I'd like to have it load the widget-set from another window, pictured at http://linus.smenet.org/~ballbee/pygtklist/log_in_form.gif into the viewport on the right on launch, and after a successful log-in, swap _that_ widget-set out (again) with the widget-set shown at http://linus.smenet.org/~ballbee/pygtklist/chronicle_properties.gif Hope that makes sense... Any help would be appreciated (even if it's a RTFM comment, if you can tell me where TFM is ::grin::) +--+ | Brian Allbee | | [EMAIL PROTECTED] | +--+ ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk

Re: [pygtk] Greetings!
This'd be using libglade (or so I presume, as the interface-prototypes were generated with glade). No manual? Hurm... Is there a (reasonably) complete list of objects/methods/properties available anywhere?

[pygtk] Tooltips in CList cells/rows
I am currently writing a CD player using pygtk and want to popup a tooltip over each track in my CList containing the full title of the track if it's not fully visible normally. I know how to do it all except attaching the tooltip to the cell/row. It should be something like: tt.set_tip(clist.get_row_data(track) But get_row_data() returns nothing, so how do I do it? Anyone? ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk
