Columns with a hard coded size that can have elements justified within it.
|
||
|
|
|
||
|
|
The Column element can have the size set to a fixed size, but when doing so, PySimpleGUI has
|
||
|
|
a limitation that the contents can't be justified using the normal element_justification parameter.
|
||
|
|
|
||
|
|
What to do?
|
||
|
|
|
||
|
|
The Sizer Element to the rescue.
|
||
|
|
|
||
|
|
PySimpleGUI likes to have layouts that size themselves rather than hard coded using a size parameter. The
|
||
|
|
Sizer Element enables you to create columns with fixed size by making the contents of your column a fixed size.
|
||
|
|
It is an invisible "padding" type of element. It has a width and a height parameter.
