XTranslateCoordinates(3)  XLIB FUNCTIONS XTranslateCoordinates(3)



NAME
       XTranslateCoordinates - translate window coordinates

SYNTAX
       Bool XTranslateCoordinates(Display *display, Window src_w,
              dest_w, int src_x, int src_y, int *dest_x_return,
              int *dest_y_return, Window *child_return);

ARGUMENTS
       child_return
                 Returns the child if the coordinates are con-
                 tained in a mapped child of the destination win-
                 dow.

       dest_w    Specifies the destination window.

       dest_x_return
       dest_y_return
                 Return the x and y coordinates within the desti-
                 nation window.

       display   Specifies the connection to the X server.

       src_w     Specifies the source window.

       src_x
       src_y     Specify the x and y coordinates within the
                 source window.

DESCRIPTION
       If XTranslateCoordinates returns True, it takes the src_x
       and src_y coordinates relative to the source window's ori-
       gin and returns these coordinates to dest_x_return and
       dest_y_return relative to the destination window's origin.
       If XTranslateCoordinates returns False, src_w and dest_w
       are on different screens, and dest_x_return and
       dest_y_return are zero.  If the coordinates are contained
       in a mapped child of dest_w, that child is returned to
       child_return.  Otherwise, child_return is set to None.

       XTranslateCoordinates can generate a BadWindow error.

DIAGNOSTICS
       BadWindow A value for a Window argument does not name a
                 defined Window.
