Greetings,
I've been given a task to create a bunch of thin-client systems. I found a Python script that acts as a window manager and provides a simple "Connect or Shut Down" interface. It works well, but now I've been asked to adapt it for two special situations.
1. Connect HERE, Connect THERE, or Shut Down." - easy enough, just duplicated the button declaration and action code. This is posted as Rev 1. What I can't seem to do is stack the buttons vertically in the window instead of horizontally.
2. Select a connection, click Connect, or Shutdown. I'm thinking a Combo box would work for that?
I'm fairly comfortable scripting, but am an absolute Python novice. I'd appreciate a hand to jump-start the revision 1 code changes, and a pointer to a good command reference (online or book) so I can tackle the revision 2 changes.
Thanks!
Glenn
