TControl.CMParentFontChanged procedure
Handles a CM_PARENTFONTCHANGED message for the control.
Declaration
procedure CMParentFontChanged(var Message: TLMessage); messageDescription
CMParentFontChanged ensures that the Font from the Parent control
is applied to the class instance when the message is received. It applies the
PixelsPerInch setting in the Parent font (which is not included in object
persistence) to the Font in the control.
No actions are performed in the method if ParentFont is set to False, or when the Parent property has not been assigned.
The current LCL version calls the ParentFontChanged method prior to exit. It
has an empty implementation, and is maintained only for compatibility with
older versions of the LCL. The work is actually performed in this method.
