.SH NAME

XFocusChangeEvent \- FocusIn and FocusOut event structure

.SH STRUCTURES

The structure for

.ZN FocusIn  

and

.ZN FocusOut

events contains:

.LP

.Ds 0

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;

.De

.LP

When you receive these events,

the structure members are set as follows.

.LP

The type member is set to the event type constant name that uniquely identifies

it.

For example, when the X server reports a

.ZN GraphicsExpose

event to a client application, it sends an

.ZN XGraphicsExposeEvent

structure with the type member set to

.ZN GraphicsExpose .

The display member is set to a pointer to the display the event was read on.

The send_event member is set to

.ZN True

if the event came from a

.ZN 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.

.LP

The window member is set to the window on which the

.ZN FocusIn

or

.ZN 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 

.ZN NotifyNormal ,

.ZN NotifyWhileGrabbed ,

.ZN NotifyGrab ,

or

.ZN NotifyUngrab .

.LP

All 

.ZN FocusOut

events caused by a window unmap are generated after any

.ZN UnmapNotify

event; however, the X protocol does not constrain the ordering of 

.ZN FocusOut

events with respect to

generated 

.ZN EnterNotify ,

.ZN LeaveNotify ,

.ZN VisibilityNotify ,

and

.ZN Expose

events.

.LP

Depending on the event mode,

the detail member is set to indicate the notify detail and can be

.ZN NotifyAncestor ,

.ZN NotifyVirtual ,

.ZN NotifyInferior ,

.ZN NotifyNonlinear ,

.ZN NotifyNonlinearVirtual ,

.ZN NotifyPointer ,

.ZN NotifyPointerRoot ,

or

.ZN NotifyDetailNone .
