XQueryPointer(3X11) XLIB FUNCTIONS XQueryPointer(3X11)
XQueryPointer - get pointer coordinates
Bool XQueryPointer(Display *display, Window w, Window
*root_return, Window *child_return, int *root_x_return,
int *root_y_return, int *win_x_return, int
*win_y_return, unsigned int *mask_return);
child_return
Returns the child window that the pointer is
located in, if any.
display Specifies the connection to the X server.
mask_return
Returns the current state of the modifier keys and
pointer buttons.
root_return
Returns the root window that the pointer is in.
root_x_return
root_y_return
Return the pointer coordinates relative to the
root window's origin.
w Specifies the window.
win_x_return
win_y_return
Return the pointer coordinates relative to the
specified window.
The XQueryPointer function returns the root window the
pointer is logically on and the pointer coordinates relative
to the root window's origin. If XQueryPointer returns False,
the pointer is not on the same screen as the specified win-
dow, and XQueryPointer returns None to child_return and zero
to win_x_return and win_y_return. If XQueryPointer returns
True, the pointer coordinates returned to win_x_return and
win_y_return are relative to the origin of the specified
window. In this case, XQueryPointer returns the child that
contains the pointer, if any, or else None to child_return.
XQueryPointer returns the current logical state of the key-
board buttons and the modifier keys in mask_return. It sets
mask_return to the bitwise inclusive OR of one or more of
the button or modifier key bitmasks to match the current
state of the mouse buttons and the modifier keys.
