[PyQt] Loose com pointer when open a qt window
Hi all, I need some help or idea to a com problem.. I got this class: class foo(object): def setComObject(comObject): self.comO=comObject #This is a com object from a cad application def showForm(self) # use the self.comO to read some information from the cad application # Show the pyqt form as child of cad application # do somthing with the form # do somthing with the self.comO- Here if pass some time I'm not able to call any method to the com object a=foo() o=get istance of a cad application via com a.setComObject(o) a.showForm() # here if pass some time I'm not able to call any method to the com object but I I' re call the a.setComObject(o) #Faster and I take less the 30 seconds on the form object it works well It seems a problem of the garbage collector .. but I'm not sure how to debug it .. any help is really appreciated.. it's the last dangerous bug in our application ...

[PyQt] Menu icons missing in Xfce
Hi, I have a Python 3/PyQt 4 application that has standard menus and toolbars and works fine under GNOME 2 on Debian 6. However, on Xubuntu (Xfce 4.8) the icons only show up in the toolbars not in the menus. Yet other applications (e.g., firefox, Archive Manager) have icons in their menus. Does anyone know the fix for this?
