TControl.DoFloatMsg

Handler called when the control starts floating.

Declaration

Source position: controls.pp line 1400

protected procedure TControl.DoFloatMsg(

  ADockSource: TDragDockObject

); virtual;

Arguments

ADockSource

  

The DockObject of the current drag-dock operation.

Description

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.
