* @short_description: A vertical box which paints as many actors as it can fit
|
|
||||||
*
|
|
||||||
* This is a "flexible" box which will paint as many actors as it can within
|
|
||||||
* its given allocation; its minimum height request will be the sum of the
|
|
||||||
* mimimum size for the #StOverflowBox:min-children property, which is
|
|
||||||
* by default 0.
|
|
||||||
*
|
|
||||||
* Every child will be allocated the full width of the box, and always be
|
|
||||||
* given its preferred height. Even if not actually painted, every child
|
|
||||||
* is counted for overall preferred width/height.
