group box with title

[Guest_imported]

Can I do the group box like below in tk? I saw in a demo but do not understand how it was done. I don't think a frame can do that.

---- Group ------------

But frame can do!

  pack [frame .f -bg gold -width 100 -height 100]
  pack propagate .f 0
  pack [button .f.b1 -text 1] -side left
  pack [button .f.b2 -text 2] -side right

All subwidgets of the frame are displayed inside the frame.
To declare a widget a subwidget of an other widget, you make its path a subpath of the path of the parent.
Here the buttons are subwidgets of the frame becase their path .f.b1 or .f.b2 is a subpath of .f.

Normally the frame is sized to just contain its subwidgets.
So I added a [pack propagate .f 0] to avoid that and show a bigger frame. You can remove it to watch what appends.

Placing a subwidget inside its parent is a subtle task.

Good luck
