The problem stated... For things liek dialogs, in order for your dialogs to
remain intact after saving, exiting, and reloading, you have to wither create
all of your widgets for dialogs in procedures, or in main{}. This is a bit of
a pain.
Also, any code you make must be abstracted from the actual widgetnames using
global aliases, substituted root names, etc. Quite problematic for a project
that does much that is useful.
It it however, terrific for whipping together a GUI. This is how I've used it:
Create all dialogs, the main window widgets, widget bindings etc in vtcl, save
and exit. Edit the resultant file (which is full of truncated, meaningless
widgetnames) and replace them with a sane naming convention. Then add in your
own TCL/tk code manually.
I realize that vtcl and the program you are creatting are operation in the same
namespace, and this causes necessity for widgetname abstraction, but it really
is a pain and makes serious application building unfeasible using vtcl.
Hopefully people don't take offense to my comments. I use vtcl regularly and
it's a great GUI creation tool, but it cannot be used to actually code a
program, at least not without completely altering your programming style and
practices to bend to its will.
So for now, I build the GUI framework using vtcl, edit the resultant code, and
do the rest by hand.
