wxPython并在菜单栏中选择时添加选项菜单

Question

I have set up a wxpython GUI that has a menu bar and some items in the menu bar. What I would like to do is select an item in my menu bar (ex. File - Options), and when i select "Options" have a dialog box pop up in which I can set different parameters in my code. Similar behaviors would be wx.FontDialog and wx.FileDialog -- However, I want mine to be custom in that i could have radio buttons and check boxes as selectable options. How do I do this?

Snippets of my code are:

Here is where I set up part of the Main application and GUI (I have layout and box sizers set up in another section):

class TMainForm(wx.Frame):

    def __init__(self, *args, **kwds):

            kwds["style"] = wx.DEFAULT_FRAME_STYLE
            wx.Frame.__init__(self, *args, **kwds)
            self.Splitter = wx.SplitterWindow(self, -1, style=wx.SP_3D|wx.SP_BORDER)
            self.PlotPanel = wx.Panel(self.Splitter, -1)
            self.FilePanel = wx.Panel(self.Splitter, -1)
            #self.SelectionPanel = wx.Panel(self.Splitter,-1)
            self.Notebook = wx.Notebook(self.FilePanel, -1)#, style=0)
            self.ReportPage = wx.Panel(self.Notebook, -1)
            self.FilePage = wx.Panel(self.Notebook, -1)

Here is where I set up part of the Menu Bar:

            self.MainMenu = wx.MenuBar()
            self.FileMenu = wx.Menu()
            self.OptimizeMenu = wx.Menu()
            self.HelpMenu = wx.Menu()
            self.OptimizeOptions= wx.MenuItem(self.OptimizeMenu, 302, "&Select Parameters","Select Parameters for Optimization",wx.ITEM_NORMAL)
            self.OptimizeMenu.AppendItem(self.OptimizeOptions)

            self.MainMenu.Append(self.OptimizeMenu, "&Optimization")

Here is where I bind an event to my "options" part of my menu bar. When I click on this, I want a pop up menu dialog to show up

self.Bind(wx.EVT_MENU, self.OnOptimizeOptions, self.OptimizeOptions)

This is the function in which i'm hoping the pop up menu will be defined. I would like to do it in this format if possible (rather than doing separate classes).

def OnOptimizeOptions(self,event):
        give me a dialog box (radio buttons, check boxes, etc)

I have only shown snippets, but all of my code does work. My GUI and menu bars are set up correctly - i just don't know how to get a pop up menu like the wx.FileDialog and wx.FontDialog menus. Any help would be great! Thanks

You would want to instantiate a dialog in your handler (OnOptimizeOptions). Basically you would subclass wx.Dialog and put in whatever widgets you want. Then you'd instantiate it in your handler and call ShowModal. Something like this psuedo-code:

myDlg = MyDialog(*args)
myDlg.ShowModal()

See the Custom Dialog part on zetcodes site: http://zetcode.com/wxpython/dialogs/ (near the bottom) for one example.

EDIT - Here's an example:

import wx

########################################################################
class MyDialog(wx.Dialog):
    """"""

    #----------------------------------------------------------------------
    def __init__(self):
        """Constructor"""
        wx.Dialog.__init__(self, None, title="Options")

        radio1 = wx.RadioButton( self, -1, " Radio1 ", style = wx.RB_GROUP )
        radio2 = wx.RadioButton( self, -1, " Radio2 " )
        radio3 = wx.RadioButton( self, -1, " Radio3 " )

        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(radio1, 0, wx.ALL, 5)
        sizer.Add(radio2, 0, wx.ALL, 5)
        sizer.Add(radio3, 0, wx.ALL, 5)

        for i in range(3):
            chk = wx.CheckBox(self, label="Checkbox #%s" % (i+1))
            sizer.Add(chk, 0, wx.ALL, 5)
        self.SetSizer(sizer)

        # Add a panel so it looks the correct on all platforms
        self.panel = wx.Panel(self, wx.ID_ANY)

        menuBar = wx.MenuBar()
        fileMenu = wx.Menu()

        optionsItem = fileMenu.Append(wx.NewId(), "Options", 
                                      "Show an Options Dialog")
        self.Bind(wx.EVT_MENU, self.onOptions, optionsItem)

        exitMenuItem = fileMenu.Append(wx.NewId(), "Exit",
                                       "Exit the application")
        self.Bind(wx.EVT_MENU, self.onExit, exitMenuItem)

        menuBar.Append(fileMenu, "&File")
        self.SetMenuBar(menuBar)

    #----------------------------------------------------------------------

        dlg = MyDialog()
        dlg.ShowModal()
        dlg.Destroy()
