DESCRIPTION
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, Notify‐
Pointer,
* NotifyPointerRoot, NotifyDetailNone
*/ } XFocusChangeEvent; typedef XFocusChangeEvent XFo‐
cusInEvent; typedef XFocusChangeEvent XFocusOutEvent;
When you receive these events, the structure members are set as fol‐
lows.
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 struc‐
ture 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, Notify‐
Grab, 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, NotifyPointer‐
Root, or NotifyDetailNone.
