* The stretch factors are not applied linearly, but they are used together with both the preferred size, maximum size to form the
|
|
* internal effective stretch factor.
|
|
* There is only need to apply stretch factors if the size of the layout is different than the layouts preferred size.
|
|
* (If the size of the layout is the preferred size, then all items should get their preferred sizes.
|
|
* However, imagine this use case:
|
|
* Layout
|
|
* +----------+----------+----------+
|
|
* name | A | B | C |
|
|
* stretch | 1 | 2 | 3 |
|
|
* sizehints|[5,10,50] |[5,10,50] |[5,10,50] |
|
|
* +----------+----------+----------+
|
|
*
|
|
* layout->resize(120, h)
|
|
*
|
|
* In QLayout, C would become 50, B would become 50 and A would get 20. When scaling a layout this would give a jerky feeling, since
|
|
* the item with the highest stretch factor will first resize. When that has reached its maximum the next candidate for stretch will
|
|
* resize, and finally, item with the lowest stretch factor will resize.
|
|
* In QGraphicsLinearLayout we try to scale all items so that they all reach their maximum at the same time. This means that
|
|
* their relative sizes are not proportional to their stretch factors.
