unsigned short | modifiers |
unsigned long | timestamp |
string | event_string |
boolean | is_text |
A structure which encapsulates information about a device event.
A string representation of the event. If is_text is True
, then this string represents the character or typographic sequence that would be received by a focussed text input field. event_string is in general suitable for exposure to the end-user for purposes of keyboard echo.
a numeric code which is hardware and system-dependent, identifying the specific hardware button or key on the device for which the event has occurred. On X Window systems, for global key notifications and for most non-global key notifications as well, this code corresponds to the XKeycode. For switch and button events it indicates the switch or button number.
an identifier which identifies this event in the event stream. On X Window systems this corresponds to the XEvent serial number.
True
if the event results in the insertion of characters into an input text buffer, or would do so if delivered to a focussed text input field. ¨Typographical¨ key events have this field set to True
, whereas ¨control¨ key events generally do not.
unsigned short Accessibility::DeviceEvent::modifiers |
an unsigned short int consisting of zero or more of the following values OR'ed together:
1<<MODIFIER_SHIFT
(=1, corresponds to Xlib's ShiftMask) 1<<MODIFIER_SHIFTLOCK
(=2, corresponds to Xlib's LockMask) 1<<MODIFIER_CONTROL
(=4, corresponds to Xlib's ControlMask) 1<<MODIFIER_ALT
(=8, corresponds to Xlib's Mod1Mask) 1<<MODIFIER_META
(=16, corresponds to Xlib's Mod2Mask) 1<<MODIFIER_META2
(=32, corresponds to Xlib's Mod3Mask) 1<<MODIFIER_META3
(=64, corresponds to Xlib's Mod4Mask) unsigned long Accessibility::DeviceEvent::timestamp |
an unsigned integer representing the time that the event occurred. On X Window systems this event is a time in milliseconds from some arbitrary starting point; it therefore has a cycle time of approximately 50 days.
Identifies the type of the containing DeviceEvent.
