\wxheading{Event table macros}

To process a key event, use these event handler macros to direct input to member
functions that take a wxKeyEvent argument.

\membersection{wxKeyEvent::m\_altDown}

\member{bool}{m\_altDown}

TRUE if the Alt key is pressed down.

\membersection{wxKeyEvent::m\_controlDown}

\member{bool}{m\_controlDown}

TRUE if control is pressed down.

\membersection{wxKeyEvent::m\_keyCode}

\member{long}{m\_keyCode}

Virtual keycode. See \helpref{Keycodes}{keycodes} for a list of identifiers.

\membersection{wxKeyEvent::m\_metaDown}

\member{bool}{m\_metaDown}

TRUE if the Meta key is pressed down.

\membersection{wxKeyEvent::m\_shiftDown}

\member{bool}{m\_shiftDown}

TRUE if shift is pressed down.

\membersection{wxKeyEvent::m\_x}

\member{int}{m\_x}

X position of the event.

\membersection{wxKeyEvent::m\_y}

\member{int}{m\_y}

Y position of the event.

\membersection{wxKeyEvent::wxKeyEvent}

\func{}{wxKeyEvent}{\param{WXTYPE}{ keyEventType}}

Constructor. Currently, the only valid event types are wxEVT\_CHAR and wxEVT\_CHAR\_HOOK.

\membersection{wxKeyEvent::AltDown}

\constfunc{bool}{AltDown}{\void}

Returns TRUE if the Alt key was down at the time of the key event.

\membersection{wxKeyEvent::ControlDown}

\constfunc{bool}{ControlDown}{\void}

Returns TRUE if the control key was down at the time of the key event.

\membersection{wxKeyEvent::GetKeyCode}

\constfunc{int}{GetKeyCode}{\void}

Returns the virtual key code. ASCII events return normal ASCII values,
while non-ASCII events return values such as {\bf WXK\_LEFT} for the
left cursor key. See \helpref{Keycodes}{keycodes} for a full list of the virtual key codes.

\membersection{wxKeyEvent::GetX}

\constfunc{long}{GetX}{\void}

Returns the X position of the event.

\membersection{wxKeyEvent::GetY}

\constfunc{long}{GetY}{\void}

Returns the Y position of the event.

\membersection{wxKeyEvent::MetaDown}

\constfunc{bool}{MetaDown}{\void}

Returns TRUE if the Meta key was down at the time of the key event.

\membersection{wxKeyEvent::GetPosition}

\constfunc{wxPoint}{GetPosition}{\void}

\constfunc{void}{GetPosition}{\param{long *}{x}, \param{long *}{y}}

Obtains the position at which the key was pressed.

\membersection{wxKeyEvent::HasModifiers}

\constfunc{bool}{HasModifiers}{\void}

Returns TRUE if either of {\sc Ctrl}, {\sc Alt} or {\sc Meta} keys was down
at the time of the key event. Note that this function does not take into
account the {\sc Shift} key state.

\membersection{wxKeyEvent::ShiftDown}

\constfunc{bool}{ShiftDown}{\void}

Returns TRUE if the shift key was down at the time of the key event.
