Gets the width and height of a rectangle centered on the point the mouse button was pressed, within which a drag operation will not begin.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The property indicates the size, in pixels, of a rectangle centered around the point at which the mouse button was pressed. Windows uses the rectangle as a boundary within which it does not start a drag operation.
A user can hold a mouse button down and move the mouse within this area before a drag operation begins, which enables the user to click and release the mouse button easily without unintentionally starting a drag operation.
