5.17 Placeholder widget

5.17.1 Description

Using td, lr and all the other widgets, applications statically define their geometry and the widget of a window.

However some applications may need to dynamically change the widgets that are displayed, or the way (their geometry) they are displayed. This is the gap that placeholder fills.
