protected procedure TControl.DoFloatMsg( |
ADockSource: TDragDockObject |
); virtual; |
ADockSource |
|
The DockObject of the current drag-dock operation. |
Since TControls cannot float for themselves, a FloatHost site is created and the control is docked into it.
When the control already has a Parent (FloatHost site), the Parent's position and extent is adjusted to fit the DockRect as its ClientRect.
