:class:`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`.
================================= ==================================================
License And Version
===================
:class:`FlatMenu` is distributed under the wxPython license.
