TScrollingWinControl.ScreenToClient function

Declaration

function ScreenToClient(const APoint: TPoint): TPoint; override

Arguments

Function result

TPoint instance with the client-relative coordinates for the specified value.

Description

ScreenToClient is an overridden method in TScrollingWinControl.

ScreenToClient calls the inherited method to get the TPoint instance with the client coordinates used in the return value. The X and Y members in the return value are updated to reflect the current scroll offsets for the control. This gives the origin on the logical display area for the visible area on the control.

ScreenToClient is used, along with ClientToScreen, in inherited methods which respond to changes in the mouse pointer position for a control. This includes context menu display and drag-and-dock operations.
