:class:`~wx.lib.agw.flatmenu.FlatMenu` is a generic menu implementation.


Description
===========

:class:`FlatMenu`, like the name implies, it is a generic menu implementation.
I tried to provide a full functionality for menus, menubar and toolbar.


:class:`FlatMenu` supports the following features:

- Fires all the events (UI & Cmd);
- Check items;
- Separators;
- Enabled / Disabled menu items;
- Images on items;
- Toolbar support, with images and separators;
- Controls in toolbar (work in progress);
- Toolbar tools tooltips (done: thanks to Peter Kort);
- Accelerators for menus;
- Accelerators for menubar;
- Radio items in menus;
- Integration with AUI;
- Scrolling when menu is too big to fit the screen;
- Menu navigation with keyboard;
- Drop down arrow button to the right of the menu, it always contains the
  "Customize" option, which will popup an options dialog. The dialog has the
  following abilities:

  (a) Ability to add/remove menus;
  (b) Select different colour schemes for the menu bar / toolbar;
  (c) Control various options, such as: colour for highlight menu item, draw
      border around menus (classic look only);
  (d) Toolbar floating appearance.

- Allows user to specify grey bitmap for disabled menus/toolbar tools;
- If no grey bitmap is provided, it generates one from the existing bitmap;
- Hidden toolbar items / menu bar items - will appear in a small popmenu
  to the right if they are hidden;
- 4 different colour schemes for the menu bar (more can easily added);
- Scrolling is available if the menu height is greater than the screen height;
- Context menus for menu items;
- Show/hide the drop down arrow which allows the customization of :class:`FlatMenu`;
- Multiple columns menu window;
- Tooltips for menus and toolbar items on a :class:`StatusBar` (if present);
- Transparency (alpha channel) for menu windows (for platforms supporting it);
- FileHistory support through a pure-Python :class:`FileHistory` implementation;
- Possibility to set a background bitmap for a :class:`FlatMenu`;
- First attempt in adding controls to FlatToolbar;
- Added a MiniBar (thanks to Vladiuz);
- Added :class:`ToolBar` methods AddCheckTool/AddRadioTool (thanks to Vladiuz).


Usage
=====

Usage example::

    import wx
    import wx.lib.agw.flatmenu as FM

    class MyFrame(wx.Frame):

        def __init__(self, parent):

            wx.Frame.__init__(self, parent, -1, "FlatMenu Demo")

            self.CreateMenu()

            panel = wx.Panel(self, -1)
            btn = wx.Button(panel, -1, "Hello", (15, 12), (100, 120))

            main_sizer = wx.BoxSizer(wx.VERTICAL)
            main_sizer.Add(self.menubar, 0, wx.EXPAND)
            main_sizer.Add(panel, 1, wx.EXPAND)

            self.SetSizer(main_sizer)
            main_sizer.Layout()


        def CreateMenu(self):

            self.menubar = FM.FlatMenuBar(self, -1)

            f_menu = FM.FlatMenu()
            e_menu = FM.FlatMenu()
            v_menu = FM.FlatMenu()
            t_menu = FM.FlatMenu()
            w_menu = FM.FlatMenu()

            # Append the menu items to the menus
            f_menu.Append(-1, "Simple\tCtrl+N", "Text", None)
            e_menu.Append(-1, "FlatMenu", "Text", None)
            v_menu.Append(-1, "Example", "Text", None)
            t_menu.Append(-1, "Hello", "Text", None)
            w_menu.Append(-1, "World", "Text", None)

            # Append menus to the menubar
            self.menubar.Append(f_menu, "&File")
            self.menubar.Append(e_menu, "&Edit")
            self.menubar.Append(v_menu, "&View")
            self.menubar.Append(t_menu, "&Options")
            self.menubar.Append(w_menu, "&Help")


    # our normal wxApp-derived class, as usual

    app = wx.App(0)

    frame = MyFrame(None)
    app.SetTopWindow(frame)
    frame.Show()

    app.MainLoop()



Supported Platforms
===================

:class:`FlatMenu` has been tested on the following platforms:
  * Windows (Windows XP, Vista);
  * Linux Ubuntu (Dapper 6.06)



Window Styles
=============

This class supports the following window styles:

========================= =========== ==================================================
Window Styles             Hex Value   Description
========================= =========== ==================================================
``FM_OPT_IS_LCD``                 0x1 Use this style if your computer uses a LCD screen.
``FM_OPT_MINIBAR``                0x2 Use this if you plan to use the toolbar only.
``FM_OPT_SHOW_CUSTOMIZE``         0x4 Show "customize link" in the `More` menu, you will need to write your own handler. See demo.
``FM_OPT_SHOW_TOOLBAR``           0x8 Set this option is you are planning to use the toolbar.
========================= =========== ==================================================


Events Processing
=================

This class processes the following events:

================================= ==================================================
Event Name                        Description
================================= ==================================================
``EVT_FLAT_MENU_DISMISSED``       Used internally.
``EVT_FLAT_MENU_ITEM_MOUSE_OUT``  Fires an event when the mouse leaves a :class:`FlatMenuItem`.
``EVT_FLAT_MENU_ITEM_MOUSE_OVER`` Fires an event when the mouse enters a :class:`FlatMenuItem`.
``EVT_FLAT_MENU_SELECTED``        Fires the :class:`EVT_MENU` event for :class:`FlatMenu`.
================================= ==================================================
