\section{\class{wxToolBar}}\label{wxtoolbar}

The name wxToolBar is defined to be a synonym for one of the following classes:

\begin{itemize}\itemsep=0pt
\item {\bf wxToolBar95} The native Windows 95 toolbar. Used on Windows 95, NT 4 and above.
\item {\bf wxToolBarMSW} A Windows implementation. Used on 16-bit Windows.
\item {\bf wxToolBarGTK} The GTK toolbar.
\item {\bf wxToolBarSimple} A simple implementation, with scrolling.
Used on platforms with no native toolbar control, or where scrolling is required.
\end{itemize}

Note that the base class {\bf wxToolBarBase} defines
automatic scrolling management functionality which is identical
to \helpref{wxScrolledWindow}{wxscrolledwindow}, so please refer to this class also.
Not all toolbars support scrolling, but wxToolBarSimple does.

\wxheading{Derived from}

wxToolBarBase\\
\helpref{wxControl}{wxcontrol}\\
\helpref{wxWindow}{wxwindow}\\
\helpref{wxEvtHandler}{wxevthandler}\\
\helpref{wxObject}{wxobject}

\wxheading{Include files}

<wx/toolbar.h> (to allow wxWindows to select an appropriate toolbar class)\\
<wx/tbarbase.h> (the base class)\\
<wx/tbarmsw.h> (the non-Windows 95 Windows toolbar class)\\
<wx/tbar95.h> (the Windows 95/98 toolbar class)\\
<wx/tbarsmpl.h> (the generic simple toolbar class)

\wxheading{Remarks}

You may also create a toolbar that is managed by the frame, by
calling \helpref{wxFrame::CreateToolBar}{wxframecreatetoolbar}.

{\bf wxToolBar95:} Note that this toolbar paints tools to reflect user-selected colours.
The toolbar orientation must always be {\bf wxVERTICAL}.

\wxheading{Window styles}

\twocolwidtha{5cm}
\begin{twocollist}\itemsep=0pt
\twocolitem{\windowstyle{wxTB\_FLAT}}{Gives the toolbar a flat look ('coolbar' or 'flatbar' style). Windows 95 only.}
\twocolitem{\windowstyle{wxTB\_HORIZONTAL}}{Specifies horizontal layout.}
\twocolitem{\windowstyle{wxTB\_VERTICAL}}{Specifies vertical layout (not available for the Windows 95
toolbar).}
\twocolitem{\windowstyle{wxTB\_3DBUTTONS}}{Gives wxToolBarSimple a mild 3D look to its buttons.}
\end{twocollist}

See also \helpref{window styles overview}{windowstyles}.

\wxheading{Event handling}

The toolbar class emits menu commands in the same was that a frame menubar does,
so you can use one EVT\_MENU macro for both a menu item and a toolbar button.
The event handler functions take a wxCommandEvent argument. For most event macros,
the identifier of the tool is passed, but for EVT\_TOOL\_ENTER the toolbar
window is passed and the tool id is retrieved from the wxCommandEvent.
This is because the id may be -1 when the mouse moves off a tool, and -1 is not
allowed as an identifier in the event system.

\twocolwidtha{7cm}
\begin{twocollist}\itemsep=0pt
\twocolitem{{\bf EVT\_TOOL(id, func)}}{Process a wxEVT\_COMMAND\_TOOL\_CLICKED event
(a synonym for wxEVT\_COMMAND\_MENU\_SELECTED). Pass the id of the tool.}
\twocolitem{{\bf EVT\_MENU(id, func)}}{The same as EVT\_TOOL.}
\twocolitem{{\bf EVT\_TOOL\_RANGE(id1, id2, func)}}{Process a wxEVT\_COMMAND\_TOOL\_CLICKED event
for a range id identifiers. Pass the ids of the tools.}
\twocolitem{{\bf EVT\_MENU\_RANGE(id1, id2, func)}}{The same as EVT\_TOOL\_RANGE.}

\twocolitem{{\bf EVT\_TOOL\_RCLICKED(id, func)}}{Process a wxEVT\_COMMAND\_TOOL\_RCLICKED event.
Pass the id of the tool.}
\twocolitem{{\bf EVT\_TOOL\_RCLICKED\_RANGE(id1, id2, func)}}{Process a wxEVT\_COMMAND\_TOOL\_RCLICKED event
for a range of ids. Pass the ids of the tools.}
\twocolitem{{\bf EVT\_TOOL\_ENTER(id, func)}}{Process a wxEVT\_COMMAND\_TOOL\_ENTER event.
Pass the id of the toolbar itself. The value of wxCommandEvent::GetSelection is the tool id, or -1 if the mouse cursor has moved off a tool.}

\membersection{wxToolBar::wxToolBar}\label{wxtoolbarconstr}

\func{}{wxToolBar}{\void}

Default constructor.

\func{}{wxToolBar}{\param{wxWindow*}{ parent}, \param{wxWindowID }{id},
 \param{const wxPoint\& }{pos = wxDefaultPosition},
 \param{const wxSize\& }{size = wxDefaultSize},
 \param{long }{style = wxTB\_HORIZONTAL \pipe wxNO\_BORDER},
 \param{const wxString\& }{name = wxPanelNameStr}}

Constructs a toolbar.

\wxheading{Parameters}

\docparam{parent}{Pointer to a parent window.}

\docparam{id}{Window identifier. If -1, will automatically create an identifier.}

\docparam{pos}{Window position. wxDefaultPosition is (-1, -1) which indicates that wxWindows
should generate a default position for the window. If using the wxWindow class directly, supply
an actual position.}

\docparam{size}{Window size. wxDefaultSize is (-1, -1) which indicates that wxWindows
should generate a default size for the window.}

\docparam{style}{Window style. See \helpref{wxToolBar}{wxtoolbar} for details.}

\docparam{name}{Window name.}

\wxheading{Remarks}

After a toolbar is created, you use \helpref{wxToolBar::AddTool}{wxtoolbaraddtool} and
perhaps \helpref{wxToolBar::AddSeparator}{wxtoolbaraddseparator}, and then you
must call \helpref{wxToolBar::Realize}{wxtoolbarrealize} to construct and display the toolbar
tools.

You may also create a toolbar that is managed by the frame, by
calling \helpref{wxFrame::CreateToolBar}{wxframecreatetoolbar}.

\membersection{wxToolBar::\destruct{wxToolBar}}

\func{void}{\destruct{wxToolBar}}{\void}

Toolbar destructor.

\membersection{wxToolBar::AddSeparator}\label{wxtoolbaraddseparator}

\func{void}{AddSeparator}{\void}

Adds a separator for spacing groups of tools.

\docparam{bitmap2}{The second bitmap specifies the on-state bitmap for a toggle
tool. If this is NULL, either an inverted version of the primary bitmap is
used for the on-state of a toggle tool (monochrome displays) or a black
border is drawn around the tool (colour displays). Note that to pass a NULL value,
you need to cast it to (wxBitmap *) so that C++ can construct an appropriate temporary
wxBitmap object.}

\docparam{xPos}{Specifies the x position of the tool if automatic layout is not suitable.}

\docparam{yPos}{Specifies the y position of the tool if automatic layout is not suitable.}

\docparam{clientData}{An optional pointer to client data which can be
retrieved later using \helpref{wxToolBar::GetToolClientData}{wxtoolbargettoolclientdata}.}

\docparam{shortHelpString}{Used for displaying a tooltip for the tool in the
Windows 95 implementation of wxButtonBar. Pass the empty string if this is not required.}

\docparam{longHelpString}{Used to displayer longer help, such as status line help.

\membersection{wxToolBar::Layout}\label{wxtoolbarlayout}

\func{void}{Layout}{\void}

Called by the application after the tools have been added to
automatically lay the tools out on the window. If you have given
absolute positions when adding the tools, do not call this.

This function is only implemented for some toolbar classes.
The portable way of calling it is to call \helpref{wxToolBar::Realize}{wxtoolbarrealize} after
you have added tools and separators.

\wxheading{See also}

\helpref{wxToolBar::AddTool}{wxtoolbaraddtool}, \helpref{wxToolBar::Realize}{wxtoolbarrealize}

\membersection{wxToolBar::OnLeftClick}\label{wxtoolbaronleftclick}

\func{bool}{OnLeftClick}{\param{int}{ toolIndex}, \param{bool}{ toggleDown}}

Called when the user clicks on a tool with the left mouse button.

This is the old way of detecting tool clicks; although it will still work,
you should use the EVT\_MENU or EVT\_TOOL macro instead.

\wxheading{Parameters}

\docparam{toolIndex}{The identifier passed to \helpref{wxToolBar::AddTool}{wxtoolbaraddtool}.}

\docparam{toggleDown}{TRUE if the tool is a toggle and the toggle is down, otherwise is FALSE.}

\helpref{wxToolBar::OnMouseEnter}{wxtoolbaronmouseenter},\rtfsp
\helpref{wxToolBar::OnRightClick}{wxtoolbaronrightclick}

\membersection{wxToolBar::OnMouseEnter}\label{wxtoolbaronmouseenter}

\func{void}{OnMouseEnter}{\param{int}{ toolIndex}}

This is called when the mouse cursor moves into a tool or out of
the toolbar.

This is the old way of detecting mouse enter events; although it will still work,
you should use the EVT\_TOOL\_ENTER macro instead.

\wxheading{Parameters}

\docparam{toolIndex}{Greater than -1 if the mouse cursor has moved into the tool,
or -1 if the mouse cursor has moved. The
programmer can override this to provide extra information about the tool,
such as a short description on the status line.}

\wxheading{Remarks}

With some derived toolbar classes, if the mouse moves quickly out of the toolbar, wxWindows may not be able to
detect it. Therefore this function may not always be called when expected.

\membersection{wxToolBar::OnRightClick}\label{wxtoolbaronrightclick}

\func{void}{OnRightClick}{\param{int}{ toolIndex}, \param{float}{ x}, \param{float}{ y}}

Called when the user clicks on a tool with the right mouse button. The
programmer should override this function to detect right tool clicks.

This is the old way of detecting tool right clicks; although it will still work,
you should use the EVT\_TOOL\_RCLICKED macro instead.

\wxheading{Parameters}

\docparam{toolIndex}{The identifier passed to \helpref{wxToolBar::AddTool}{wxtoolbaraddtool}.}

\docparam{x}{The x position of the mouse cursor.}

\docparam{y}{The y position of the mouse cursor.}

\wxheading{Remarks}

A typical use of this member might be to pop up a menu.

\helpref{wxToolBar::OnLeftClick}{wxtoolbaronleftclick}

\membersection{wxToolBar::Realize}\label{wxtoolbarrealize}

\func{bool}{Realize}{\void}

This function should be called after you have added tools. It
calls, according to the implementation,
either \helpref{wxToolBar::CreateTools}{wxtoolbarcreatetools} or
 \helpref{wxToolBar::Layout}{wxtoolbarlayout}.

If you are using absolute positions for your tools when using a wxToolBarSimple object,
do not call this function. You must call it at all other times.

\membersection{wxToolBar::SetToolBitmapSize}\label{wxtoolbarsettoolbitmapsize}

\func{void}{SetToolBitmapSize}{\param{const wxSize\&}{ size}}

Sets the default size of each tool bitmap. The default bitmap size is 16 by 15 pixels.

\wxheading{Parameters}

\docparam{size}{The size of the bitmaps in the toolbar.}

\wxheading{Remarks}

This should be called to tell the toolbar what the tool bitmap size is. Call
it before you add tools.

Note that this is the size of the bitmap you pass to \helpref{wxToolBar::AddTool}{wxtoolbaraddtool},
and not the eventual size of the tool button.

\docparam{size}{Margin size.}

\docparam{x}{Left margin, right margin and inter-tool separation value.}

\docparam{y}{Top margin, bottom margin and inter-tool separation value.}

\wxheading{Remarks}

This must be called before the tools are added if absolute positioning is to be used, and the
default (zero-size) margins are to be overridden.
