Re: [MACTCL] Some bugs?

Jim,

Filed: 894561 & 894550

'Fraid I wasn't able to track down the buttons not appearing bug any 
further - I can't reproduce the problem outside of TkChat, even trying 
various combinations of wm withdraw, wm transient, wm overrideredirect 
etc. Really not sure what is going wrong. The other bug, I managed to 
narrow down a bit further - seems -cursor {} is ignored when 
configuring the widget in an event callback, for instance:

pack [canvas .c]
.c configure -cursor hand
after 5000 [list .c configure -cursor {}]

The cursor never changes from the "hand" cursor, whereas:

.c configure -cursor hand
.c configure -cursor {}

and the widget is back to the default (arrow) cursor.

With regards to a reference for what the {} cursor name should do:

http://www.tcl.tk/man/tcl8.4/TkLib/ConfigWind.htm

is apparently the most definitive guide (and hard to track down; thanks 
to Bruce Hartweg for finding it). If "None" is specified as the cursor 
name (presumably this equates to {} at the script level), then the 
widget should use the cursor of it's parent.

Phew, hope this helps.

Neil.
