XFocusChangeEvent - FocusIn and FocusOut event structure

STRUCTURES

The structure for FocusIn and FocusOut events contains:

typedef struct {
int type; /* FocusIn or FocusOut */
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 window; /* window of event */
int mode; /* NotifyNormal, NotifyGrab, NotifyUngrab */
int detail;
/*
* NotifyAncestor, NotifyVirtual, NotifyInferior,
* NotifyNonlinear,NotifyNonlinearVirtual, NotifyPointer,
* NotifyPointerRoot, NotifyDetailNone
*/
} XFocusChangeEvent;
typedef XFocusChangeEvent XFocusInEvent;
typedef XFocusChangeEvent XFocusOutEvent;

When you receive these events, 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 window member is set to the window on which the FocusIn or
FocusOut event was generated. This is the window used by the X
server to report the event. The mode member is set to indicate
whether the focus events are normal focus events, focus events while
grabbed, focus events when a grab activates, or focus events when a
grab deactivates. The X server can set the mode member to
NotifyNormal, NotifyWhileGrabbed, NotifyGrab, or NotifyUngrab.

All FocusOut events caused by a window unmap are generated after any
UnmapNotify event; however, the X protocol does not constrain the
ordering of FocusOut events with respect to generated EnterNotify,
LeaveNotify, VisibilityNotify, and Expose events.

Depending on the event mode, the detail member is set to indicate the
notify detail and can be NotifyAncestor, NotifyVirtual,
NotifyInferior, NotifyNonlinear, NotifyNonlinearVirtual,
NotifyPointer, NotifyPointerRoot, or NotifyDetailNone.
