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_window_t root;


    int16_t      x;


    int16_t      y;


    uint16_t     width;


    uint16_t     height;


    uint16_t     border_width;


    uint8_t      pad0[2];
} 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_t *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);
}
