a couple of mac menu problems

Hi,

I'm trying to develop a cross-platform Tkinter app.

Here's a bit of code used to create the Help menu:

    if MAC:
	self.master.createcommand("tkAboutDialog", self.about_action)
	self.master.createcommand("::tk::mac::ShowHelp",
		self.help_action)
    helpMenu = tk.Menu(self.menubar, name="help")
    helpMenu.add_command(label="Help", underline=0,
	    command=self.help_action)
    if not MAC:
	helpMenu.add_command(label="About", underline=0,
		command=self.about_action)
    self.menubar.add_cascade(label="Help", underline=0,
	    menu=helpMenu)

I end up with these menus:

    ActivePython3.2 
	About ActivePython3.2 # correctly invokes my about action
	...

    Help
	Search # some apple-specific thing that just appears
	ActivePython3.2 Help # invokes my help action
	Help                 # invokes my help action
(Continue reading)

There's some magic in the Tk-Cocoa help menu--if you define the 
tk::mac::showHelp command and map it to your function that calls user 
help, you don't need to add a separate entry for help. (There's already 
an entry hard-coded for help, along with the search field.) So the 
helpMenu.add_Command(label="Help")... stuff is redundant.

Re: a couple of mac menu problems

Along the same lines, I managed to get application/preferences to work on the Mac, but while
application/about shows the name of my Python app (built with pyinstaller), it displays the 'Tcl & Tk'
dialog.  

The TkDocs-TK Tutorial on menus shows this as a TODO item
(http://www.tkdocs.com/tutorial/menus.html).  While I was able to figure out the preferences menu by
looking at the idlelib sources, I couldn't get the application/about menu to work.

Any suggestions?

Re: a couple of mac menu problems

I'm testing on 10.7.4, but it needs to work on 10.6 as well.

What does "CFBundleName" in your info.plist file show? I've seen this 
bug on the system version of Tcl/Tk installed with Snow Leopard, but not 
more recently.

Here's how I get the correct application dialog in the 'about myapp" menu:

self.createcommand('tkAboutDialog', self.aboutProgram)
     #dialog for 'about program'
     def aboutProgram(self):
         self.tk.call('tk::mac::standardAboutPanel')
(You can substitute any Python bits here that you want--the key is to 
map the 'tkAboutDialog' command to some kind of Python function or method.)
