Using a used to tool (wxpython) should always be simple, but it isn't
very hard to do a modal dialog in PyQt too !
That the window flashes is because you might create a local instance,
which is destroyed at function exit !!!
You have to store your window either in a global reference or put it
into a list of known windows, where you can delete it once you don't
need it anymore (that's what I do).
self.controlledServers.append( ServerControlOv( self,
self, "Server Control", 0, 0) )
x = len(self.controlledServers)-1
It is quite easy to use container facilities of python. But most
applications will be happy with static allocation:
def open_modal_window(parent, control):
dialogA = ServerControlOv( parent, control,
"Server Control", 0, 0) )
Anyway you have to use a variable that lives longer than your open
