Expand description

Priority for stretching widgets beyond ideal size

When more space is available than required to meet widgets’ “ideal size”, that extra space is allocated based on the Stretch priority: the widget(s) with the highest priority level represented are allocated extra space (the excess is evenly divided between these widgets).

Note that Stretch only affects how much space is made available, not how that space is used. By default, widgets expand to fill all space made available to them; any other behaviour requires alignment.

Variants§

§

None

Prefer no stretching

This is the default value and indicates that stretching is undesirable, but does not prevent it.

§

Filler

Fill unwanted space

The main use of this is to force layout with a Filler widget.

§

Low

Extra space is considered of low utility (but higher than Filler)

§

High

Extra space is considered of high utility

§

Maximize

Greedily consume as much space as possible
