XTranslateCoordinates(3) XLIB FUNCTIONS 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
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.
