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.
