Pack

The pack geometry manager places a widget by stacking it against one side of its parent. This page is the method spec; Arranging widgets teaches when to reach for pack.

In ttkbootstrap pack (and pack_configure) return the widget, so construction and placement can be chained.

The canonical upstream reference is the Tk pack manual page (Tcl 8.6).

Options

Every option below is a keyword argument to pack().

Option	Type	Description
side	str	The side of the remaining space the widget stacks against: "top" (default), "bottom", "left", or "right".
fill	str	Stretch the widget to fill its slot: "x", "y", "both", or "none" (default).
expand	bool	Claim a share of the parent’s leftover space — the slot grows; pair with fill so the widget grows with it.
anchor	str	Where the widget sits inside its slot when it does not fill it: "center", a side ("n"/"s"/"e"/"w"), or a corner ("ne", "sw", …).
padx pady	int | tuple	External space around the widget, in pixels. A (left, right) / (top, bottom) tuple pads the two sides differently.
ipadx ipady	int	Internal padding added to the widget’s own size, in pixels.
before after	Widget	Insert the widget into the packing order relative to a sibling that is already packed.
in_	Widget	Pack inside a container other than the parent (the container must be the parent or one of its descendants). Rarely needed.

Methods

Returns:

None.

pack_info()

Return the widget’s current pack options.

Return type:

dict

pack_propagate(flag=None)
