tkinter - How to stop frame changing size when widget is added?
Grid accepts the parameter uniform
, which takes an arbitrary value. All rows (or all columns) with the same value are considered to be part of a "uniform group". This forces the rows (or columns) to be a uniform size in proportion to their weight.
If you have two rows in a frame, both rows have an identical weight, and both belong to the same uniform group, they will each take up exactly 50% of the available space.
In your case you can do this:
innerFrame.grid_rowconfigure(0, weight=1, uniform="x")innerFrame.grid_rowconfigure(1, weight=1, uniform="x")
(again, the "x" is arbitrary; it can be any value as long as it's the same value for both rows)
The official documentation for tk (upon which tkinter is built) describes it like this (see http://tcl.tk/man/tcl8.5/TkCmd/grid.htm#M24)
The -uniform option, when a non-empty value is supplied, places the row in a uniform group with other rows that have the same value for -uniform. The space for rows belonging to a uniform group is allocated so that their sizes are always in strict proportion to their -weight values.
...
When multiple rows or columns belong to a uniform group, the space allocated to them is always in proportion to their weights. (A weight of zero is considered to be 1.) In other words, a row or column configured with -weight 1 -uniform a will have exactly the same size as any other row or column configured with -weight 1 -uniform a. A row or column configured with -weight 2 -uniform b will be exactly twice as large as one that is configured with -weight 1 -uniform b.
Note: the uniform
option doesn't show up in the tkinter documentation, but it is a perfectly valid option. It has been a part of tk (upon which tkinter is built) for many, many years.
You can use a max-size
, min-sixe
to the frame:
master = tk()master.minsize(width=777, height=777)master.maxsize(width=777, height=777)
