- UnitType - a type of measure units. You can choose between Star (relative values) and Pixel (absolute values).
- UnitValue - a size value. Depending on the UnitType value, this number is interpreted as either an absolute value in pixels, or as a relative value compared to other star-typed Length objects.
Using these properties, you can resize widgets, but only one property will work at a time. For instance, if one widget is docked to another widget's side so that both documents are arranged horizontally, only the FreeLayoutWidth property will be in effect. The FreeLayoutHeight property of both containers will be ignored since document height is managed by the docking container that hosts these documents.
