ToasterBox is a cross-platform widget to make the creation of MSN style "toaster"
popups easier.


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

ToasterBox is a cross-platform widget to make the creation of MSN style "toaster"
popups easier. The syntax is really easy especially if you are familiar with the
syntax of wxPython.

It has 2 main styles:

- ``TB_SIMPLE``: using this style, you will be able to specify a background image for
  ToasterBox, text properties as text colour, font and label;

- ``TB_COMPLEX``: this style will allow you to put almost any control inside a
  ToasterBox. You can add a panel in which you can put all the controls you like.

Both styles support the setting of ToasterBox position (on screen coordinates),
size, the time after which the ToasterBox is destroyed (linger), and the scroll
speed of ToasterBox.


Usage
=====

Usage example::

    import wx
    import wx.lib.agw.toasterbox as TB

    class MyFrame(wx.Frame):

        def __init__(self, parent):
        
            wx.Frame.__init__(self, parent, -1, "ToasterBox Demo")

            toaster = TB.ToasterBox(self, tbstyle=TB.TB_COMPLEX)
            toaster.SetPopupPauseTime(3000)

            tbpanel = toaster.GetToasterBoxWindow()
            panel = wx.Panel(tbpanel, -1)
            sizer = wx.BoxSizer(wx.VERTICAL)

            button = wx.Button(panel, wx.ID_ANY, "Simple button")
            sizer.Add(button, 0, wx.EXPAND)

            panel.SetSizer(sizer)
            toaster.AddPanel(panel)

            wx.CallLater(1000, toaster.Play)


    # our normal wxApp-derived class, as usual

    app = wx.PySimpleApp()

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

    app.MainLoop()



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

ToasterBox has been tested on the following platforms:

- Windows (verified on Windows XP, 2000)
- Linux
- Mac


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

This class supports the following window styles:

==================== =========== ==================================================
Window Styles        Hex Value   Description
==================== =========== ==================================================
``TB_SIMPLE``                0x1 A simple `ToasterBox`, with background image and text customization can be created.
``TB_ONTIME``                0x1 `ToasterBox` will close after a specified amount of time.
``TB_COMPLEX``               0x2 ToasterBoxes with different degree of complexity can be created. You can add as  many controls as you want, provided that you call the L{AddPanel} method and pass  to it a dummy frame and a `wx.Panel`. See the demo for details.
``TB_ONCLICK``               0x2 `ToasterBox` can be closed by clicking anywhere on the `ToasterBox` frame.
``TB_DEFAULT_STYLE``   0x2008002 Default window style for `ToasterBox`, with no caption nor close box.
``TB_CAPTION``        0x22009806 `ToasterBox` will have a caption, with the possibility to set a title for the `ToasterBox` frame, and a close box.
==================== =========== ==================================================
