I don't know if it is a Tk limitation, but it's possible.
Windows 3.1 had a limit where a listbox would only allocate 64K of memory.
After a few thousand items the listbox couldn't add any more strings. So
you
had to use a "virtual" listbox instead, containing only the visible part
and update
it as you scroll.
I don't know if the same type of trick can be done with the canvas widget
though...
For Visual Tcl you would need Tk 8.3.2 though. You can install it at the
same time
as Tk 8.0.5 I think.

| Subject: [vtcl-user] frame max height 32768?
|
|
|
>-----------------------------------------------------------------------------------------------------------|
Hello,
I have a question about frame widgets - I think.
I have a frame that I have created in a scrollable canvas. This frame
occasionally gets a height attribute as high as 50000+. It appears that
the
displayed frame widget is being limited to 32768 pixels, causing the rest
of
my frame to be hidden. Is this a limitation of Tk? Any ideas?
I am using (and am limited to using) Tcl/Tk 8.0.5 on a Windows NT platform.
Thanks,
Dave Ofstead
