You don't pass objectes to widgets as a rule.
There is absolutely no need for global variables here either.
If you run into scoping conflicts, you are doing something very wrong.
I would think a few days spent in some sort of training would probably
rapidly sort a lot of the difficulties.
I have been picking away at this stuff for quite a while in between
various other acivities. I was using Kate as an editor with a small
script and makefile to compile and run each iteration - just doing a
simple widget program to drive a radio synthesizer board.
An object specifying various frequency parameters (eg sweep
start/stop/step in floats) mode etc would be modified by a setup dialog.
I could call the dialog from the main program event handler, and get
data to it via a validator. However, couldnt for the life of me get
modified data back.
I'll look at Ruby for the moment and go back to it later ...
Thanks anyway for your assistance
Richard
