XQueryPointer(3X11) X11R5 XQueryPointer(3X11)NAMEXQueryPointer - get pointer coordinates
SYNTAX
Bool XQueryPointer(display, w, root_return, child_return,
root_x_return, root_y_return,
win_x_return, win_y_return, mask_return)
Display *display;
Window w;
Window *root_return, *child_return;
int *root_x_return, *root_y_return;
int *win_x_return, *win_y_return;
unsigned int *mask_return;
ARGUMENTS
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 win‐
dow.
DESCRIPTION
The function returns the root window the pointer is logically on and
the pointer coordinates relative to the root window's origin. If
returns the pointer is not on the same screen as the specified window,
and returns to child_return and zero to win_x_return and win_y_return.
If returns the pointer coordinates returned to win_x_return and
win_y_return are relative to the origin of the specified window. In
this case, returns the child that contains the pointer, if any, or else
to child_return.
returns the current logical state of the keyboard buttons and the modi‐
fier 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.
can generate a error.
DIAGNOSTICS
A value for a Window argument does not name a defined Window.
