  23
  24 \member{bool}{m\_altDown}
  25
  26 TRUE if the Alt key is pressed down.
  27
  28 \membersection{wxKeyEvent::m\_controlDown}
  29
  30 \member{bool}{m\_controlDown}
  31
  32 TRUE if control is pressed down.
  33
  34 \membersection{wxKeyEvent::m\_keyCode}
  35
  36 \member{long}{m\_keyCode}
  37
  38 Virtual keycode. See \helpref{Keycodes}{keycodes} for a list of identifiers.
  39
  40 \membersection{wxKeyEvent::m\_metaDown}
  41
  42 \member{bool}{m\_metaDown}
  43
  44 TRUE if the Meta key is pressed down.
  45
  46 \membersection{wxKeyEvent::m\_shiftDown}
  47
  48 \member{bool}{m\_shiftDown}
  49
  50 TRUE if shift is pressed down.
  51
  52 \membersection{wxKeyEvent::m\_x}
  53
  54 \member{int}{m\_x}
  55
  56 X position of the event.
  57
  58 \membersection{wxKeyEvent::m\_y}
  59
  60 \member{int}{m\_y}
  61
  62 Y position of the event.

  65
  66 \func{}{wxKeyEvent}{\param{WXTYPE}{ keyEventType}}
  67
  68 Constructor. Currently, the only valid event types are wxEVT\_CHAR and wxEVT\_CHAR\_HOOK.
  69
  70 \membersection{wxKeyEvent::AltDown}
  71
  72 \func{bool}{AltDown}{\void}
  73
  74 Returns TRUE if the Alt key was down at the time of the key event.
  75
  76 \membersection{wxKeyEvent::ControlDown}
  77
  78 \func{bool}{ControlDown}{\void}
  79
  80 Returns TRUE if the control key was down at the time of the key event.
  81
  82 \membersection{wxKeyEvent::GetX}
  83
  84 \func{float}{GetX}{\void}
  85
  86 Returns the X position of the event.
  87
  88 \membersection{wxKeyEvent::GetY}

  93
  94 \membersection{wxKeyEvent::KeyCode}
  95
  96 \func{long}{KeyCode}{\void}
  97
  98 Returns the virtual key code. ASCII events return normal ASCII values,
  99 while non-ASCII events return values such as {\bf WXK\_LEFT} for the
 100 left cursor key. See \helpref{Keycodes}{keycodes} for a full list of the virtual key codes.
 101

 107
 108 \membersection{wxKeyEvent::Position}
 109
 110 \func{void}{Position}{\param{float *}{x}, \param{float *}{y}}
 111
 112 Obtains the position at which the key was pressed.
 113
 114 \membersection{wxKeyEvent::ShiftDown}
 115
 116 \func{bool}{ShiftDown}{\void}
