SYNTAX

9       Bool  XQueryPointer(Display  *display,  Window  w, Window *root_return,
10              Window *child_return, int  *root_x_return,  int  *root_y_return,
11              int  *win_x_return,  int  *win_y_return,  unsigned int *mask_re‐
12              turn);
13

ARGUMENTS

15       child_return
16                 Returns the child window that the pointer is located  in,  if
17                 any.
18
19       display   Specifies the connection to the X server.
20
21       mask_return
22                 Returns  the  current  state of the modifier keys and pointer
23                 buttons.
24
25       root_return
26                 Returns the root window that the pointer is in.
27
28       root_x_return
29       root_y_return
30                 Return the pointer coordinates relative to the root  window's
31                 origin.
32
33       w         Specifies the window.
34
35       win_x_return
36       win_y_return
37                 Return the pointer coordinates relative to the specified win‐
38                 dow.

DESCRIPTION

41       The XQueryPointer function returns the root window the pointer is logi‐
42       cally on and the pointer coordinates relative to the root window's ori‐
43       gin.  If XQueryPointer returns False, the pointer is not  on  the  same
44       screen  as  the  specified  window,  and  XQueryPointer returns None to
45       child_return and zero to win_x_return  and  win_y_return.   If  XQuery‐
46       Pointer  returns True, the pointer coordinates returned to win_x_return
47       and win_y_return are relative to the origin of  the  specified  window.
48       In  this  case,  XQueryPointer  returns  the  child  that  contains the
49       pointer, if any, or else None to child_return.
50
51       XQueryPointer returns the current logical state of the keyboard buttons
52       and  the modifier keys in mask_return.  It sets mask_return to the bit‐
53       wise inclusive OR of one or more of the button or modifier key bitmasks
54       to match the current state of the mouse buttons and the modifier keys.
55
56       XQueryPointer can generate a BadWindow error.

DIAGNOSTICS

59       BadWindow A value for a Window argument does not name a defined Window.
