taken from field

Property for overriding the region's computed minimum height. This should only be set if the region's internally computed minimum height doesn't meet the application's layout needs.

Defaults to the USE_COMPUTED_SIZE flag, which means that minHeight(forWidth) will return the region's internally computed minimum height.

Setting this value to the USE_PREF_SIZE flag will cause minHeight(forWidth) to return the region's preferred height, enabling applications to easily restrict the resizability of the region.
