  12 \section{\class{wxCaret}}\label{wxcaret}
  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 \perlnote{In wxPerl there are two methods instead of a single overloaded
  76 method:\par
  77 \indented{2cm}{\begin{twocollist}
  78 \twocolitem{{\bf GetPosition()}}{Returns a Wx::Point}
  79 \twocolitem{{\bf GetPositionXY()}}{Returns a 2-element list
  80  {\tt ( x, y )}}
  81 \end{twocollist}
  82 }}
  83
  84 \membersection{wxCaret::GetSize}\label{wxcaretgetsize}
  85
  86 \constfunc{void}{GetSize}{\param{int* }{width}, \param{int* }{height}}
  87
  88 \constfunc{wxSize}{GetSize}{\void}
  89
  90 Get the caret size.
  91
  92 \perlnote{In wxPerl there are two methods instead of a single overloaded
  93 method:\par
  94 \indented{2cm}{\begin{twocollist}
  95 \twocolitem{{\bf GetSize()}}{Returns a Wx::Size}
  96 \twocolitem{{\bf GetSizeWH()}}{Returns a 2-element list
  97  {\tt ( width, height )}}
  98 \end{twocollist}
  99 }}
 100
 101 \membersection{wxCaret::GetWindow}\label{wxcaretgetwindow}
 102
 103 \constfunc{wxWindow*}{GetWindow}{\void}
 104
 105 Get the window the caret is associated with.
 106
 107 \membersection{wxCaret::Hide}\label{wxcarethide}
 108
 109 \func{void}{Hide}{\void}
 110
 111 Same as \helpref{wxCaret::Show(false)}{wxcaretshow}.
 112
 113 \membersection{wxCaret::IsOk}\label{wxcaretisok}
 114
 115 \constfunc{bool}{IsOk}{\void}
 116
 117 Returns true if the caret was created successfully.
 118
 119 \membersection{wxCaret::IsVisible}\label{wxcaretisvisible}
 120
 121 \constfunc{bool}{IsVisible}{\void}
 122
 123 Returns true if the caret is visible and false if it is permanently
 124 hidden (if it is is blinking and not shown currently but will be after the
 125 next blink, this method still returns true).
 126
 127 \membersection{wxCaret::Move}\label{wxcaretmove}
 128
 129 \func{void}{Move}{\param{int }{x}, \param{int }{y}}
 130
 131 \func{void}{Move}{\param{const wxPoint\& }{pt}}
 132
 133 Move the caret to given position (in logical coordinates).
 134
 135 \membersection{wxCaret::SetBlinkTime}\label{wxcaretsetblinktime}
 136
 137 \func{static void}{SetBlinkTime}{\param{int }{milliseconds}}
 138
 139 Sets the blink time for all the carets.
 140
 141 \wxheading{Remarks}
 142
 143 Under Windows, this function will change the blink time for {\bf all} carets
 144 permanently (until the next time it is called), even for the carets in other
 145 applications.
 146
 147 \wxheading{See also}
 148
 149 \helpref{GetBlinkTime}{wxcaretgetblinktime}
 150
 151 \membersection{wxCaret::SetSize}\label{wxcaretsetsize}
 152
 153 \func{void}{SetSize}{\param{int }{width}, \param{int }{height}}
 154
 155 \func{void}{SetSize}{\param{const wxSize\& }{size}}
 156
 157 Changes the size of the caret.
 158
 159 \membersection{wxCaret::Show}\label{wxcaretshow}
 160
 161 \func{void}{Show}{\param{bool }{show = true}}
 162
 163 Shows or hides the caret. Notice that if the caret was hidden $N$ times, it
 164 must be shown $N$ times as well to reappear on the screen.
