TControl.MouseCapture property

Declaration

property MouseCapture: Boolean read GetMouseCapture write SetMouseCapture;

Description

In normal operation, all mouse messages are sent to the control under the mouse pointer. Mouse messages also can be sent to a capturing control, e.g. when a control is dragged.

Applications should capture mouse events only for special purposes, and release the capture as soon as a the target position has been determined. Limited user feedback is possible while the mouse is captured, not all application controls will work properly so long.
