XTranslateCoordinates(3) Library Functions Manual XTranslateCoordinates(3) 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 co- ordinates relative to the source window's origin and returns these co- ordinates 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_re- turn are zero. If the coordinates are contained in a mapped child of dest_w, that child is returned to child_return. Otherwise, child_re- turn is set to None. XTranslateCoordinates can generate a BadWindow error. DIAGNOSTICS BadWindow A value for a Window argument does not name a defined Window. SEE ALSO Xlib - C Language X Interface XLIB FUNCTIONS X Version 11 XTranslateCoordinates(3)
