<var>DoMouseUp</var> is an overridden method in <var>TCustomSpeedButton</var>. It re-implements the method from TControl and does not call the inherited method. DoMouseUp checks the flag values in ControlStyle. When csNoStdEvents is not included in the values, it calls the MouseUp method using Button and Message as arguments.

|

|

DoMouseUp is called when a LM_LBUTTONUP message is handled for the control.
