Member Data Documentation

EventType Accessibility::DeviceEvent::type

Identifies the type of the containing DeviceEvent. Definition at line 294 of file Accessibility_Registry.idl.

long Accessibility::DeviceEvent::id

an identifier which identifies this event in the event stream. On X Window systems this corresponds to the XEvent serial number. Definition at line 295 of file Accessibility_Registry.idl.

short Accessibility::DeviceEvent::hw_code

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. Note: For technical reasons, this code may differ from the XKeycode when generated by Java applications for consumption by non-global key listeners. This is subject to change in future versions of the DeviceEventController implementation. Definition at line 298 of file Accessibility_Registry.idl.

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) Definition at line 311 of file Accessibility_Registry.idl.

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. Definition at line 321 of file Accessibility_Registry.idl.

string Accessibility::DeviceEvent::event_string

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. Definition at line 327 of file Accessibility_Registry.idl.

boolean Accessibility::DeviceEvent::is_text

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. Definition at line 333 of file Accessibility_Registry.idl.
