Hello there...
This is a copy of a post I made somewhere else a few hours ago, and I'd like
to see your opinions too. I've searched in this forum, and found interesting
things about the GenericDirCtrl, but couldn't solve my problem. I hope this
is not a repeated post. Here we go:
-----------ORIGINAL POST(edited a little though)-------------:
- [b]Introducing[/b]:
I’m very new with both Python and wxPython. Actually I’m new with
programming :D, started just two years ago with C, and Python a month ago. I
don’t usually ask for help, but I feel that I’m… how’s the phrase… “between
a rock and a hard place”? Well, I’ve been asked by some astrophysics
engineers to make a GUI some time ago. I already have a 5,000 lines program
in Python, ready to roll, but now they want to execute that program with an
user-friendly interface. And I’m finding it really difficult to learn… I
mean programming a GUI. The GUI program is still a WIP, so don’t worry about
the looking :P.
- [b]Problem[/b] (code in wxPython):
···
---
Some initial data:
OS: Ubuntu server.
Python version: I don’t know. I downloaded the last repository version with
apt-get, and I’m using #!/usr/bin/python, so I guess it’s 2.7.1.
GUI toolkit: wxPython?
---
The main problem is I have some events not working. I want that when I pick
a file or a directory from the tree control (with double click or just
selecting, doesn’t matter), an event triggers and the path is copied and
pasted on the text control. It seems like the EVT_TREE_SEL_CHANGED and
EVT_TREE_ITEM_ACTIVATED events don’t work for some reason, they don’t
trigger. I’ve been searching the web and trying the wxPython tutorials, but
couldn’t find anything to solve this issue. If you know where I could find
some help about this, or you want to give me a hint, please tell me.
I also have a minor problem with the help button which triggers a dialog
screen. I don’t know why, but everything (Ok button and static texts) appear
in the top left corner of the panel, despite the sizers. I changed the
positions many times with no avail. It's really scratching my head lol.
I’ve asked my colleagues to help me out, but they don’t know where's the
problem either. And they are too busy to look deep into it, so… I have no
choice but to post my problem in a forum. First time I do it, so please
don’t be bad lol.
I hope you pardon this annoying newbie ,
Alex.
