#include <wx/vscroll.h>
In any case, this is a generalization of wxScrolled which can be only used when all rows have the same heights. It lacks some other wxScrolled features however, notably it can't scroll specific pixel sizes of the window or its exact client area size.
To use this class, you need to derive from it and implement the OnGetRowHeight() pure virtual method. You also must call SetRowCount() to let the base class know how many rows it should display, but from that moment on the scrolling is handled entirely by wxVScrolledWindow. You only need to draw the visible part of contents in your OnPaint()
method as usual. You should use GetVisibleRowsBegin() and GetVisibleRowsEnd() to select the lines to display. Note that the device context origin is not shifted so the first visible row always appears at the point (0, 0) in physical as well as logical coordinates.
You are encouraged to update any existing code using these function to use the new replacements mentioned below, and avoid using these functions for any new code as they are deprecated.
size_t GetFirstVisibleLine() const | Deprecated for GetVisibleRowsBegin(). |
size_t GetLastVisibleLine() const | Deprecated for GetVisibleRowsEnd(). This function originally had a slight design flaw in that it was possible to return (size_t)-1 (ie: a large positive number) if the scroll position was 0 and the first line wasn't completely visible. |
size_t GetLineCount() const | Deprecated for GetRowCount(). |
int HitTest(wxCoord x, wxCoord y) const | Deprecated for VirtualHitTest(). |
virtual wxCoord OnGetLineHeight(size_t line) const | Deprecated for OnGetRowHeight(). |
virtual void OnGetLinesHint(size_t lineMin, size_t lineMax) const | Deprecated for OnGetRowsHeightHint(). |
virtual void RefreshLine(size_t line) | Deprecated for RefreshRow(). |
virtual void RefreshLines(size_t from, size_t to) | Deprecated for RefreshRows(). |
virtual bool ScrollLines(int lines) | Deprecated for ScrollRows(). |
virtual bool ScrollPages(int pages) | Deprecated for ScrollRowPages(). |
bool ScrollToLine(size_t line) | Deprecated for ScrollToRow(). |
void SetLineCount(size_t count) | Deprecated for SetRowCount(). |

wxVScrolledWindow () | |
Default constructor, you must call Create() later. | |
wxVScrolledWindow (wxWindow *parent, wxWindowID id=wxID_ANY, const wxPoint &pos=wxDefaultPosition, const wxSize &size=wxDefaultSize, long style=0, const wxString &name=wxPanelNameStr) | |
This is the normal constructor, no need to call Create() after using this constructor. | |
bool | Create (wxWindow *parent, wxWindowID id=wxID_ANY, const wxPoint &pos=wxDefaultPosition, const wxSize &size=wxDefaultSize, long style=0, const wxString &name=wxPanelNameStr) |
Same as the non-default constuctor, but returns a status code: true if ok, false if the window couldn't be created. |
wxVScrolledWindow::wxVScrolledWindow | ( | ) |
Default constructor, you must call Create() later.
wxVScrolledWindow::wxVScrolledWindow | ( | wxWindow * | parent, | |
wxWindowID | id = wxID_ANY , |
|||
const wxPoint & | pos = wxDefaultPosition , |
|||
const wxSize & | size = wxDefaultSize , |
|||
long | style = 0 , |
|||
const wxString & | name = wxPanelNameStr | |||
) |
This is the normal constructor, no need to call Create() after using this constructor.
wxVSCROLL
is always automatically added to the style, there is no need to specify it explicitly.parent | The parent window, must not be NULL. | |
id | The identifier of this window, wxID_ANY by default. | |
pos | The initial window position. | |
size | The initial window size. | |
style | The window style. There are no special style bits defined for this class. | |
name | The name for this window; usually not used. |
bool wxVScrolledWindow::Create | ( | wxWindow * | parent, | |
wxWindowID | id = wxID_ANY , |
|||
const wxPoint & | pos = wxDefaultPosition , |
|||
const wxSize & | size = wxDefaultSize , |
|||
long | style = 0 , |
|||
const wxString & | name = wxPanelNameStr | |||
) |
Same as the non-default constuctor, but returns a status code: true if ok, false if the window couldn't be created.
Just as with the constructor, the wxVSCROLL
style is always used, there is no need to specify it explicitly.
Reimplemented from wxPanel.
Reimplemented in wxHtmlListBox, and wxVListBox.
