XTranslateCoordinates(3) XLIB FUNCTIONS XTranslateCoordinates(3)NAMEXTranslateCoordinates - 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 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
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
BadWindow A value for a Window argument does not name a defined Window.
