xcb_get_geometry(3) XCB Requests xcb_get_geometry(3) 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 re- ceived. 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 coor- dinate specifies the upper-left outer corner relative to its par- ent'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 coor- dinate specifies the upper-left outer corner relative to its par- ent'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 call- ing the reply function xcb_get_geometry_reply. If you want to handle errors in the event loop instead, use xcb_get_geome- try_unchecked. See xcb-requests(3) for details. ERRORS xcb_drawable_error_t TODO: reasons? xcb_window_error_t TODO: reasons?
