XCreateWindowEvent − CreateNotify event structure

The structure for CreateNotify events contains:

typedef struct {
        int type;       /* CreateNotify */
        unsigned long serial;   /* # of last request processed by server */
        Bool send_event;        /* true if this came from a SendEvent request */
        Display *display;       /* Display the event was read from */
        Window parent;  /* parent of the window */
        Window window;  /* window id of window created */
        int x, y;       /* window location */
        int width, height;      /* size of window */
        int border_width;       /* border width */
        Bool override_redirect; /* creation should be overridden */
} XCreateWindowEvent;

When you receive this event, the structure members are set
as follows.

The type member is set to the event type constant name that
uniquely identifies it.  For example, when the X server
reports a GraphicsExpose event to a client application, it
sends an XGraphicsExposeEvent structure with the type member
set to GraphicsExpose.  The display member is set to a
pointer to the display the event was read on.  The
send_event member is set to True if the event came from a
SendEvent protocol request.  The serial member is set from
the serial number reported in the protocol but expanded from
the 16‐bit least‐significant bits to a full 32‐bit value.
The window member is set to the window that is most useful
to toolkit dispatchers.

The parent member is set to the created window’s parent.
The window member specifies the created window.  The x and y
members are set to the created window’s coordinates relative
to the parent window’s origin and indicate the position of
the upper‐left outside corner of the created window.  The
width and height members are set to the inside size of the
created window (not including the border) and are always
nonzero.  The border_width member is set to the width of the
created window’s border, in pixels.  The override_redirect
member is set to the override‐redirect attribute of the
window.  Window manager clients normally should ignore this
window if the override_redirect member is True.
