NAME

       xcb_get_geometry - Get current window geometry

SYNOPSIS

       #include <xcb/xproto.h>

   Request function
       xcb_get_geometry_cookie_t xcb_get_geometry(xcb_connection_t *conn,
              xcb_drawable_t drawable);

   Reply datastructure
       typedef struct xcb_get_geometry_reply_t {
           uint8_t      response_type;
           uint8_t      depth;
           uint16_t     sequence;
           uint32_t     length;

       } xcb_get_geometry_reply_t;

   Reply function
       xcb_get_geometry_reply_t *xcb_get_geometry_reply(xcb_connection_t *conn,
              xcb_get_geometry_cookie_t cookie, xcb_generic_error_t **e);

REQUEST ARGUMENTS

       conn      The XCB connection to X11.

       drawable  The drawable (Window or Pixmap) of which the geometry will be received.

REPLY FIELDS

       response_type
                 The type of this reply, in this case XCB_GET_GEOMETRY. This field is also
                 present in the xcb_generic_reply_t and can be used to tell replies apart from
                 each other.

       sequence  The sequence number of the last request processed by the X11 server.

       length    The length of the reply, in words (a word is 4 bytes).

       depth     The depth of the drawable (bits per pixel for the object).

       root      Root window of the screen containing drawable.

       x         The X coordinate of drawable. If drawable is a window, the coordinate specifies
                 the upper-left outer corner relative to its parent's origin. If drawable is a
                 pixmap, the X coordinate is always 0.

       y         The Y coordinate of drawable. If drawable is a window, the coordinate specifies
                 the upper-left outer corner relative to its parent's origin. If drawable is a
                 pixmap, the Y coordinate is always 0.

       width     The width of drawable.

       height    The height of drawable.

       border_width
                 The border width (in pixels).

DESCRIPTION

       Gets the current geometry of the specified drawable (either Window or Pixmap).

RETURN VALUE

       Returns an xcb_get_geometry_cookie_t. Errors have to be handled when calling the reply
       function xcb_get_geometry_reply.

       If you want to handle errors in the event loop instead, use xcb_get_geometry_unchecked.
       See xcb-requests(3) for details.

ERRORS

       xcb_drawable_error_t
                 TODO: reasons?

       xcb_window_error_t
                 TODO: reasons?

EXAMPLE

       /*
        * Displays the x and y position of the given window.
        *
        */
       void my_example(xcb_connection *c, xcb_window_t window) {
           xcb_get_geometry_cookie_t cookie;
           xcb_get_geometry_reply_t *reply;

           cookie = xcb_get_geometry(c, window);
           /* ... do other work here if possible ... */
           if ((reply = xcb_get_geometry_reply(c, cookie, NULL))) {
               printf("This window is at %d, %d\n", reply->x, reply->y);
           }
           free(reply);
       }
