Demonstrates how to use the Window.layout_extend method.
|
|
Layouts can be extended at the Window level or within any container element such as a Column.
|
|
This demo shows how to extend both.
|
|
Note that while you can extend, add to, a layout, you cannot delete items from a layout. Of course you
|
|
can make them invisible after adding them.
|
|
|
|
When using scrollable Columns be sure and call Column.visibility_changed so that the scrollbars will
|
|
be correctly reposititioned
