protected procedure TCustomLabel.TextChanged; override;

Description

TextChanged is an overridden method used to perform actions needed when the CM_TEXTCHANGED message is handled for the control. TextChanged calls Invalidate to request the control to be redrawn. UpdateSize is called to perform auto-sizing, and recalculate the dimensions for the control. The font may be re-sized when OptimalFill is enabled.

TextChanged does not call the inherited method.
