NAME
 XTranslateCoordinates - 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.
