Function
Atspiregister_keystroke_listener
Declaration [src]
gboolean
atspi_register_keystroke_listener (
AtspiDeviceListener* listener,
GArray* key_set,
AtspiKeyMaskType modmask,
AtspiKeyEventMask event_types,
AtspiKeyListenerSyncType sync_type,
GError** error
)
Description [src]
Registers a listener for keystroke events, either pre-emptively for
all windows (ATSPI_KEYLISTENER_ALL_WINDOWS
),
non-preemptively (ATSPI_KEYLISTENER_NOSYNC
), or
pre-emptively at the toolkit level (ATSPI_KEYLISTENER_CANCONSUME
).
If ALL_WINDOWS or CANCONSUME are used, the event is consumed
upon receipt if one of listener
‘s callbacks returns TRUE
(other sync_type values may be available in the future).
Parameters
listener
-
Type:
AtspiDeviceListener
A pointer to the
AtspiDeviceListener
for which keystroke events are requested.The data is owned by the caller of the function. key_set
-
Type: An array of
AtspiKeyDefinition*
A pointer to the
AtspiKeyDefinition
array indicating which keystroke events are requested, or NULL to indicate that all keycodes and keyvals for the specified modifier set are to be included.The argument can be NULL
.The data is owned by the caller of the function. modmask
-
Type:
AtspiKeyMaskType
An
AtspiKeyMaskType
mask indicating which key event modifiers must be set in combination withkeys
, events will only be reported for key events for which all modifiers inmodmask
are set. If you wish to listen for events with multiple modifier combinations, you must call #atspi_register_keystroke_listener once for each combination. event_types
-
Type:
AtspiKeyEventMask
An
AtspiKeyMaskType
mask indicating which types of key events are requested (ATSPI_KEY_PRESSED
etc.). sync_type
-
Type:
AtspiKeyListenerSyncType
An
AtspiKeyListenerSyncType
parameter indicating the behavior of the notification/listener transaction. error
-
Type:
GError **
The return location for a recoverable error.
The argument can be NULL
.If the return location is not NULL
, then you must initialize it to aNULL
GError*
.The argument will be left initialized to NULL
by the function if there are no errors.In case of error, the argument will be set to a newly allocated GError
; the caller will take ownership of the data, and be responsible for freeing it.
