Demo of autosize of Text Element
|
|
|
|
Beginning in version 4.46.0 the Text element will fully autosize if:
|
|
* auto_size_text is True (default)
|
|
* No size is supplied or (None, None) is supplied
|
|
|
|
"Fully autosize" means that both the element and the window will grow/shrink
|
|
as the contents of the Text element changes.
|
|
|
|
Prior versions autosized in 1 direction, either horizontally or vertically
|
|
* Set size = (None, int) to autosize horizontally
|
|
* Set size = (int, None) to autosize vertically
|
|
|
|
By default autosize is enabled, but setting a size parameter will disable unless None is specified
|
|
in one of the directions.
