Description

Returns False, no matter the value of Msg.

As a member of the TWinControl class, PreProcessMessage always returns False, no matter the value of Msg.

Note: When overriding PreProcessMessage in descendant classes, we recommend to implement it such that it returns True if Msg is a preprocess message, and False otherwise.
