XTranslateCoordinates(3X) XTranslateCoordinates(3X)
NAME
XTranslateCoordinates - translate window coordinates
SYNOPSIS
Bool XTranslateCoordinates(display, src_w, dest_w,
src_x, src_y, dest_x_return,
dest_y_return,
child_return)
Display *display;
Window src_w, dest_w;
int src_x, src_y;
int *dest_x_return, *dest_y_return;
Window *child_return;
ARGUMENTS
child_return
Returns the child if the coordinates are
contained in a mapped child of the
destination window.
dest_w Specifies the destination window.
dest_x_return
dest_y_return
Return the x and y coordinates within the
destination 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
The XTranslateCoordinates function takes the src_x and
src_y coordinates relative to the source window's
origin and returns these coordinates to dest_x_return
and dest_y_return relative to the destination window's
origin. If XTranslateCoordinates returns zero, 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.
