hiding a control

Is there a way to hide a control like a button?

Yes, you can use the option forget with the geometry manager (pack, place or grid) you used to show your widget.

Code:

button .b -text test
pack .b
after 1000 pack forget .b

You will watch the button disappear after 1 s.

To show the widget again, re-use the same geometry manager you used.
In this case

Code:

pack

retains all the configuration so you only need:

Code:

pack .b

to get the button as it was.
On my win2k box with Tk 8.3 this is not the case with

Code:

place

(you need to give again the configuration).

Good luck
