XTranslateCoordinates - Man Page
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 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.
Diagnostics
- BadWindow
A value for a Window argument does not name a defined Window.
