TCustomPage.CMHitTest procedure
Handles the CM_HITTEST control message.
Declaration
procedure CMHitTest(var Message: TLMNCHITTEST); messageArguments
Message | Control message handled in the method. |
Description
CMHitTest checks the type for the Parent control to determine whether the Message is ignored or forwarded to the inherited method. When Parent is a TCustomTabControl descendant, the class instance must be the active page in the parent control. When it is not, the Message result is set to 0 and the message is ignored. Otherwise, the inherited method is called to handle the Message.
