12 \section{\class{wxHVScrolledWindow
}}\label{wxhvscrolledwindow
}
14 This window inherits all functionality of both vertical and horizontal,
15 variable scrolled windows. It automatically handles everything needed to
16 scroll both axis simultaneously with both variable row heights and variable
19 This is a generalization of the
\helpref{wxScrolledWindow
}{wxscrolledwindow
}
20 class which can be only used when all rows and columns are the same size. It
21 lacks some other wxScrolledWindow features however, notably it can't scroll
22 only a rectangle of the window and not its entire client area.
24 To use this class, you must derive from it and implement both the
25 \helpref{OnGetRowHeight()
}{wxvarvscrollhelperongetrowheight
} and
26 \helpref{OnGetColumnWidth()
}{wxvarhscrollhelperongetcolumnwidth
} pure virtual
27 methods to let the base class know how many rows and columns it should
28 display. You also need to set the total rows and columns the window contains,
29 but from that moment on the scrolling is handled entirely by
30 wxHVScrolledWindow. You only need to draw the visible part of contents in
31 your
{\tt OnPaint()
} method as usual. You should use
32 \helpref{GetVisibleBegin()
}{wxvarhvscrollhelpergetvisiblebegin
}
33 and
\helpref{GetVisibleEnd()
}{wxvarhvscrollhelpergetvisibleend
} to select the
34 lines to display. Note that the device context origin is not shifted so the
35 first visible row and column always appear at the point $(
0,
0)$ in physical
36 as well as logical coordinates.

69 Default constructor, you must call
\helpref{Create()
}{wxhvscrolledwindowcreate
}
72 \func{}{wxHVScrolledWindow
}{\param{wxWindow*
}{parent
},
\param{wxWindowID
}{id = wxID
\_ANY},

\param{const wxSize\&
}{size = wxDefaultSize
},
\param{long
}{style =

\param{const wxString\&
}{name = wxPanelNameStr
}}
74 This is the normal constructor, no need to call
{\tt Create()
} after using this one.
76 Note that
{\tt wxHSCROLL
} and
{\tt wxVSCROLL
} are always automatically added
77 to our styles, there is no need to specify it explicitly.

85 \docparam{pos

89 \docparam{style

99 Same as the

{\tt true
} if ok,
{\tt false
} if the window couldn't
103 Just as with the constructor above, the
{\tt wxHSCROLL
} and
{\tt wxVSCROLL
}
104 styles are always used, there is no need to specify it explicitly.
