TMouse.Capture property

Declaration

property Capture: HWND read GetCapture write SetCapture;

Description

Capture is a HWND property which contains the handle for the control which has the mouse capture. Its value is read from the LCL interface (and ultimately the widgetset class instance).

Setting a new value for the property causes either SetCapture or ReleaseCapture to be called in the LCL interface (or widgetset class instance). When set to 0 (the unassigned handle value), ReleaseCapture is called. Otherwise, SetCapture is called to assign the new handle value to the widget.
