  13
  14 A caret is a blinking cursor showing the position where the typed text will
  15 appear. The text controls usually have a caret but wxCaret class also allows
  16 to use a caret in other windows.
  17
  18 Currently, the caret appears as a rectangle of the given size. In the future,
  19 it will be possible to specify a bitmap to be used for the caret shape.
  20
  21 A caret is always associated with a window and the current caret can be
  22 retrieved using \helpref{wxWindow::GetCaret}{wxwindowgetcaret}. The same caret
  23 can't be reused in two different windows.

  36
  37 \membersection{wxCaret::wxCaret}\label{wxcaretwxcaret}
  38
  39 \func{}{wxCaret}{\void}
  40
  41 Default constructor: you must use one of Create() functions later.
  42
  43 \func{}{wxCaret}{\param{wxWindow* }{window}, \param{int }{width}, \param{int }{height}}
  44
  45 \func{}{wxCaret}{\param{wxWindowBase* }{window}, \param{const wxSize\& }{size}}
  46
  47 Create the caret of given (in pixels) width and height and associates it
  48 with the given window.
  49
  50 \membersection{wxCaret::Create}\label{wxcaretcreate}
  51
  52 \func{bool}{Create}{\param{wxWindowBase* }{window}, \param{int }{width}, \param{int }{height}}
  53
  54 \func{bool}{Create}{\param{wxWindowBase* }{window}, \param{const wxSize\& }{size}}
  55
  56 Create the caret of given (in pixels) width and height and associates it
  57 with the given window (same as constructor).
  58
  59 \membersection{wxCaret::GetBlinkTime}\label{wxcaretgetblinktime}
  60
  61 \func{static int}{GetBlinkTime}{\void}
  62
  63 Returns the blink time which is measured in milliseconds and is the time elapsed
  64 between 2 inversions of the caret (blink time of the caret is the same
  65 for all carets, so this functions is static).
  66
  67 \membersection{wxCaret::GetPosition}\label{wxcaretgetposition}
  68
  69 \constfunc{void}{GetPosition}{\param{int* }{x}, \param{int* }{y}}
  70
  71 \constfunc{wxPoint}{GetPosition}{\void}
  72
  73 Get the caret position (in pixels).
  74
  75 \membersection{wxCaret::GetSize}\label{wxcaretgetsize}
  76
  77 \constfunc{void}{GetSize}{\param{int* }{width}, \param{int* }{height}}
  78
  79 \constfunc{wxSize}{GetSize}{\void}
  80
  81 Get the caret size.
  82
  83 \membersection{wxCaret::GetWindow}\label{wxcaretgetwindow}
  84
  85 \constfunc{wxWindow*}{GetWindow}{\void}
  86
  87 Get the window the caret is associated with.
  88
  89 \membersection{wxCaret::Hide}\label{wxcarethide}
  90
  91 \func{void}{Hide}{\void}
  92
  93 Same as \helpref{wxCaret::Show(FALSE)}{wxcaretshow}.
  94
  95 \membersection{wxCaret::IsOk}\label{wxcaretisok}
  96
  97 \constfunc{bool}{IsOk}{\void}
  98
  99 Returns TRUE if the caret was created successfully.
 100
 101 \membersection{wxCaret::IsVisible}\label{wxcaretisvisible}
 102
 103 \constfunc{bool}{IsVisible}{\void}
 104
 105 Returns TRUE if the caret is visible and FALSE if it is permanently
 106 hidden (if it is is blinking and not shown currently but will be after the
 107 next blink, this method still returns TRUE).
 108
 109 \membersection{wxCaret::Move}\label{wxcaretmove}
 110
 111 \func{void}{Move}{\param{int }{x}, \param{int }{y}}
 112
 113 \func{void}{Move}{\param{const wxPoint\& }{pt}}
 114
 115 Move the caret to given position (in logical coordinates).
 116
 117 \membersection{wxCaret::SetBlinkTime}\label{wxcaretsetblinktime}
 118
 119 \func{static void}{SetBlinkTime}{\param{int }{milliseconds}}
 120
 121 Sets the blink time for all the carets.
 122
 123 \wxheading{Remarks}
 124
 125 Under Windows, this function will change the blink time for {\bf all} carets
 126 permanently (until the next time it is called), even for the carets in other
 127 applications.
 128
 129 \wxheading{See also}
 130
 131 \helpref{GetBlinkTime}{wxcaretgetblinktime}
 132
 133 \membersection{wxCaret::SetSize}\label{wxcaretsetsize}
 134
 135 \func{void}{SetSize}{\param{int }{width}, \param{int }{height}}
 136
 137 \func{void}{SetSize}{\param{const wxSize\& }{size}}
 138
 139 Changes the size of the caret.
 140
 141 \membersection{wxCaret::Show}\label{wxcaretshow}
 142
 143 \func{void}{Show}{\param{bool }{show = TRUE}}
 144
 145 Shows or hides the caret. Notice that if the caret was hidden $N$ times, it
 146 must be shown $N$ times as well to reappear on the screen.
