XQueryPointer __libmansuffix__ __xorgversion__ "XLIB FUNCTIONS"
NAME
XQueryPointer - get pointer coordinates
SYNTAX
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\^);
ARGUMENTS
child_return 1i
Returns the child window that the pointer is located in, if any.
display 1i
Specifies the connection to the X server.
mask_return 1i
Returns the current state of the modifier keys and pointer buttons.
root_return 1i
Returns the root window that the pointer is in.
root_x_return 1i
.ns
root_y_return 1i
Return the pointer coordinates relative to the root window's origin.
w 1i
Specifies the window.
win_x_return 1i
.ns
win_y_return 1i
Return the pointer coordinates relative to the specified window.
DESCRIPTION
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 window, 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 keyboard 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.
XQueryPointer can generate a BadWindow error.
DIAGNOSTICS
1i BadWindow A value for a Window argument does not name a defined Window.
