Detailed Description
A container that allows reflowing its children.
A FlowBox positions child widgets in sequence according to its orientation.
For instance, with the horizontal orientation, the widgets will be arranged from left to right, starting a new row under the previous row when necessary. Reducing the width in this case will require more rows, so a larger height will be requested.
Likewise, with the vertical orientation, the widgets will be arranged from top to bottom, starting a new column to the right when necessary. Reducing the height will require more columns, so a larger width will be requested.
The children of a FlowBox can be dynamically sorted and filtered.
Although a FlowBox must have only FlowBoxChild children, you can add any kind of widget to it via Container::add() , and a FlowBoxChild widget will automatically be inserted between the box and the widget.
Also see ListBox .
