    @class wxToolBar

    A toolbar is a bar of buttons and/or other controls usually placed below
    the menu bar in a wxFrame.

    You may create a toolbar that is managed by a frame calling
    wxFrame::CreateToolBar(). Under Pocket PC, you should always use this
    function for creating the toolbar to be managed by the frame, so that
    wxWidgets can use a combined menubar and toolbar. Where you manage your
    own toolbars, create wxToolBar as usual.

    There are several different types of tools you can add to a toolbar.
    These types are controlled by the ::wxItemKind enumeration.

    Note that many methods in wxToolBar such as wxToolBar::AddTool return a
    @c wxToolBarToolBase* object.
    This should be regarded as an opaque handle representing the newly added
    toolbar item, providing access to its id and position within the toolbar.
    Changes to the item's state should be made through calls to wxToolBar methods,
    for example wxToolBar::EnableTool.
    Calls to @c wxToolBarToolBase methods (undocumented by purpose) will not change
    the visible state of the item within the the tool bar.

    <b>wxMSW note</b>: Note that under wxMSW toolbar paints tools to reflect
    system-wide colours. If you use more than 16 colours in your tool bitmaps,
    you may wish to suppress this behaviour, otherwise system colours in your
    bitmaps will inadvertently be mapped to system colours.
    To do this, set the msw.remap system option before creating the toolbar:
    @code
    wxSystemOptions::SetOption("msw.remap", 0);
    @endcode
    If you wish to use 32-bit images (which include an alpha channel for
    transparency) use:
    @code
    wxSystemOptions::SetOption("msw.remap", 2);
    @endcode
    Then colour remapping is switched off, and a transparent background
    used. But only use this option under Windows XP with true colour:
    @code
    if (wxTheApp->GetComCtl32Version() >= 600 && ::wxDisplayDepth() >= 32)
    @endcode

    @beginStyleTable
    @style{wxTB_FLAT}
        Gives the toolbar a flat look (Windows and GTK only).
    @style{wxTB_DOCKABLE}
        Makes the toolbar floatable and dockable (GTK only).
    @style{wxTB_HORIZONTAL}
        Specifies horizontal layout (default).
    @style{wxTB_VERTICAL}
        Specifies vertical layout.
    @style{wxTB_TEXT}
        Shows the text in the toolbar buttons; by default only icons are shown.
    @style{wxTB_NOICONS}
        Specifies no icons in the toolbar buttons; by default they are shown.
    @style{wxTB_NODIVIDER}
        Specifies no divider (border) above the toolbar (Windows only)
    @style{wxTB_NOALIGN}
        Specifies no alignment with the parent window (Windows only, not very
        useful).
    @style{wxTB_HORZ_LAYOUT}
        Shows the text and the icons alongside, not vertically stacked (Windows
        and GTK 2 only). This style must be used with @c wxTB_TEXT.
    @style{wxTB_HORZ_TEXT}
        Combination of @c wxTB_HORZ_LAYOUT and @c wxTB_TEXT.
    @style{wxTB_NO_TOOLTIPS}
        Don't show the short help tooltips for the tools when the mouse hovers
        over them.
    @style{wxTB_BOTTOM}
        Align the toolbar at the bottom of parent window.
    @style{wxTB_RIGHT}
        Align the toolbar at the right side of parent window.
    @endStyleTable

    See also @ref overview_windowstyles. Note that the wxMSW native toolbar
    ignores @c wxTB_NOICONS style. Also, toggling the @c wxTB_TEXT works only
    if the style was initially on.

    @beginEventEmissionTable{wxCommandEvent}
    @event{EVT_TOOL(id, func)}
        Process a @c wxEVT_COMMAND_TOOL_CLICKED event (a synonym for @c
        wxEVT_COMMAND_MENU_SELECTED). Pass the id of the tool.
    @event{EVT_MENU(id, func)}
        The same as EVT_TOOL().
    @event{EVT_TOOL_RANGE(id1, id2, func)}
        Process a @c wxEVT_COMMAND_TOOL_CLICKED event for a range of
        identifiers. Pass the ids of the tools.
    @event{EVT_MENU_RANGE(id1, id2, func)}
        The same as EVT_TOOL_RANGE().
    @event{EVT_TOOL_RCLICKED(id, func)}
        Process a @c wxEVT_COMMAND_TOOL_RCLICKED event. Pass the id of the
        tool.  (Not available on wxOSX.)
    @event{EVT_TOOL_RCLICKED_RANGE(id1, id2, func)}
        Process a @c wxEVT_COMMAND_TOOL_RCLICKED event for a range of ids. Pass
        the ids of the tools.  (Not available on wxOSX.)
    @event{EVT_TOOL_ENTER(id, func)}
        Process a @c 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.  (Not available on wxOSX.)
    @event{EVT_TOOL_DROPDOWN(id, func)}
        Process a @c wxEVT_COMMAND_TOOL_DROPDOWN_CLICKED event. If unhandled,
        displays the default dropdown menu set using
        wxToolBar::SetDropdownMenu().
    @endEventTable

    The toolbar class emits menu commands in the same way 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 identifier is passed and the tool identifier is retrieved
    from the wxCommandEvent. This is because the identifier may be @c wxID_ANY when the
    mouse moves off a tool, and @c wxID_ANY is not allowed as an identifier in the event
    system.
