Center a column in a window
|
||
|
|
|
||
|
|
Solves a very specific kind of layout.
|
||
|
|
If you want to have something centered in a Window, this is a good way to do it
|
||
|
|
The "trick" here is:
|
||
|
|
* the first row of the layout has a Text element that expands vertically
|
||
|
|
* the row with the Column has a text element that expands horizontally
|
||
|
|
|
||
|
|
This expanding Text element is what will cause the Column element to be centered
