XTranslateCoordinates - translate window coordinates
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);
- 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.
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 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.
- BadWindow
- A value for a Window argument does not name a defined Window.
