The toolbar family of classes allows an application to use toolbars
in a variety of configurations and styles.

Instead of supplying one toolbar class with a number

out the classes. This is because there are a number of different toolbar

+toolbar implementations will emerge which
+cannot all be shoe-horned into the one class.
-This does mean that if you wish to use a more sophisticated toolbar
-on one platform (say, wxToolBar95) and a simple toolbar on another
-platform (wxToolBarSimple), then you will need some simple ifdefing, such as:
-
-\begin{verbatim}
- #ifdef wx_msw
- # define wxToolBar wxToolBar95
- #else
- # define wxToolBar wxToolBarSimple
- #endif
-\end{verbatim}
-
-Fortunately, the APIs of the toolbar classes are virtually identical.
+For each platform, the symbol {\bf wxToolBar} is defined to be one of the
+specific toolbar classes.
The following is a summary of the toolbar classes and their differences.
\begin{itemize}\itemsep=0pt
\item {\bf wxToolBarBase.} This is a base class with pure virtual functions,
and should not be used directly.
-\item {\bf wxToolBarSimple.} A simple toolbar class written entirely with generic wxWindows
-functionality. A simply 3D effect for buttons is possible, but it is not consistent
+\item {\bf wxToolBarSimple.} A simple toolbar class written entirely with generic wxWidgets
+functionality. A simple 3D effect for buttons is possible, but it is not consistent
with the Windows look and feel. This toolbar can scroll, and you can have arbitrary
numbers of rows and columns.
\item {\bf wxToolBarMSW.} This class implements an old-style Windows toolbar, only on
Windows. There are small, three-dimensional buttons, which do not (currently) reflect
-the current Windows colour settings: the buttons are grey.
+the current Windows colour settings: the buttons are grey. This is the default wxToolBar
+on 16-bit windows.
\item {\bf wxToolBar95.} Uses the native Windows 95 toolbar class. It dynamically adjusts its
background and button colours according to user colour settings.
CreateTools must be called after the tools have been added.
No absolute positioning is supported but you can specify the number
-of rows, and add tool separators with {\bf AddSeparator}. {\bf Layout} does nothing.
-Tooltips are supported. {\bf OnRightClick} is not supported.
-For some reason, a wxToolBar95 control cannot be moved to any
-position other than the top-left of the frame.
+of rows, and add tool separators with {\bf AddSeparator}.
+Tooltips are supported. {\bf OnRightClick} is not supported. This is the default wxToolBar
+on Windows 95, Windows NT 4 and above. With the style wxTB\_FLAT, the flat toolbar
+look is used, with a border that is highlighted when the cursor moves over the buttons.
\end{itemize}
A toolbar might appear as a single row of images under
the desired result).
The Windows-specific toolbar classes expect 16-colour bitmaps that are 16 pixels wide and 15 pixels
-high. If you want to use a different size, call {\bf SetDefaultSize}\rtfsp
+high. If you want to use a different size, call {\bf SetToolBitmapSize}\rtfsp
as the demo shows, before adding tools to the button bar. Don't supply more than
one bitmap for each tool, because the toolbar generates all three images (normal,
depressed and checked) from the single bitmap you give it.
-Mouse click events for a given button are sent to a member called
-\rtfsp{\bf OnLeftClick}, and so an application must derive from wxToolBar in order
-to use it. The application can also handle {\bf OnMouseEnter} events for
-the tools, to give the user extra feedback about the tools as the mouse
-moves over them.

\subsection{Using the toolbar library}
-Include one of the files {\tt tbarsmpl.h, tbar95.h, tbarmsw.h}.
+Include {\tt "wx/toolbar.h"}, or if using a class directly, one of:
-Example of toolbar use are given in the sample programs tbarsmpl,
-tbarmsw and tbar95.
+\begin{itemize}\itemsep=0pt
+\item {\tt "wx/msw/tbarmsw.h} for wxToolBarMSW
+\item {\tt "wx/msw/tbar95.h} for wxToolBar95
+\item {\tt "wx/tbarsmpl.h} for wxToolBarSimple
+\end{itemize}
-Each sample creates a main window, and two toolbars: a floating toolbar
-with 24 tools, and a toolbar along the top of the main drawing window, divided into groups.
+Example of toolbar use are given in the sample program ``toolbar''. The
+source is given below. In fact it is out of date because recommended
+practise is to use event handlers (using EVT\_MENU or EVT\_TOOL) instead of
+overriding OnLeftClick.
-The test program defines a general-purpose derived frame called
-\rtfsp{\bf wxFrameWithToolBar} which can manage a frame with one main subwindow
-and one horizontal toolbar.
