procedure MouseUp(Button: TMouseButton; Shift: TShiftState; X, Y: Single);
void __fastcall MouseUp(System::Uitypes::TMouseButton Button, System::Classes::TShiftState Shift, float X, float Y);
OnMouseUp event dispatcher.
Override the protected MouseUp method to provide other responses in addition to calling the OnMouseUp event handler when the user releases a previously pressed mouse button while the cursor's hot spot is over the control.
A 3D control calls MouseUp in response to any mouse-up events, decoding the message parameters into the shift key state and position, which it passes in the
Y parameters, respectively. The value of the
Button parameter indicates which mouse button was released: left, right, or middle.
