Name

MapNotify,UnmapNotify — (generated event).

When Generated

The X server generates MapNotify and UnmapNotify events when a window changes state from unmapped to mapped or vice versa.

Select With

To receive these events on a single window, use StructureNotifyMask in the call to XSelectInput for the window. To receive these events for all children of a particular parent, specify the parent window ID and use SubstructureNotifyMask.

XEvent Structure Name

typedef union _XEvent {
   ...
   XMapEvent xmap;
   XUnmapEvent xunmap;
   ...
} XEvent;

Event Structure

typedef struct {
   int type;
   unsigned long serial;      /* # of last request processed by server */
   Bool send_event;           /* True if this came from SendEvent request */
   Display *display;          /* Display the event was read from */
   Window event;
   Window window;
   Bool override_redirect;    /* boolean, is override set */
} XMapEvent;
typedef struct {
   int type;
   unsigned long serial;      /* # of last request processed by server */
   Bool send_event;           /* True if this came from SendEvent request */
   Display *display;          /* Display the event was read from */
   Window event;
   Window window;
   Bool from_configure;
} XUnmapEvent;

Event Structure Members

`event`		The window that selected this event.
`window`		The window that was just mapped or unmapped.
`override_redirect` (`XMapEvent` only)		`True` or `False`. The value of the `override_redirect` attribute of the window that was just mapped.
`from_configure` (`XUnmapEvent` only)		`True` if the event was generated as a result of a resizing of the window's parent when the window itself had a `win_gravity` of `UnmapGravity`. See the description of the `win_gravity` attribute in 4.3.4 of Volume One. `False` otherwise.
