As explained above, there is a packing dialog, where
widgets can be selected, packed and rearranged (see figure
). This dialog
is activated with the menu item (Configuration
| Packing). The description of the packer given in the
introduction to Tk
explains the options that are available
in the packing dialog.
It is also possible to pack widgets directly when the layout dialog is activated (or when layouting is always allowed). Selecting a widget by pressing the the mouse button 1 (it has to be pressed together with the Modifier1 key), moves the widget to the border of the parent that is the closest for the mouse pointer. In the layout window, some parameters like fill, expand etc. can be set.
When layouting with the packer, it is important to group widgets with frame widgets. The user can use the frames as row-column widgets. All children of one frame are usually packed to one side of the parent.
