XTranslateCoordinates(3X11)XTranslateCoordinates(3X11)NAMEXTranslateCoordinates - 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
Returns the child if the coordinates are contained in a mapped child of
the destination window. Specifies the destination window. Return the
x and y coordinates within the destination window. Specifies the con‐
nection to the X server. Specifies the source window. 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 origin and returns these
coordinates to dest_x_return and dest_y_return relative to the destina‐
tion 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
A value for a Window argument does not name a defined Window.
