TControl.CalculateDockSizes procedure
Saves the docked and undocked extent of the control.
Declaration
procedure CalculateDockSizesDescription
In the floating state, it sets UndockWidth/Height to the current Width/Height. In docked state, it sets LRDockWidth/TBDockHeight to the current Width/Height.
Should save both in any case, independent from DockOrientation or host Align.
Rationale: a DockManager will either ignore these values, or use them
according to the
new
alignment. Without a DockManager both
extents are required, because no (valid) alignment information applies.
