[Pyobjc-dev] NSWindow launched from statusItem menuItem does not appear

[David M. <da...@my...>]

Hi,

I have a statusItem based application written in PyObjC. The  
statusItem has a menuItem which is supposed to launch a new window  
when it is clicked.

In my AppDelegate.py
...
menuitem =  
NSMenuItem.alloc().initWithTitle_action_keyEquivalent_('Preferences',  
'launchPreferences:', '')
menu.addItem_(menuitem)
...

The launchPreferences method:

def launchPreferences_(self, notification):
     NSLog('AppDelegate: launchPreferences')
     self.preferences = Preferences.alloc().init()
     self.preferences.showWindow_(self)

which is creating a new object from Preferences.py

class Preferences(NSWindowController):

where I have:

def init(self):
     NSLog('Preferences: init')
     self = super(Preferences, self).init()
     self.initWithWindowNibName_('Preferences')
     return self

When I run the application in XCode (Build & Go), this works fine.  
However, when I run the built .app file externally from XCode, the  
statusItem and menuItem appear as expected but when I click on the  
Preferences menuItem the window does not appear. I have verified that  
the launchPreferences code is running by checking console output.

Further, if I then double click the .app file again, the window  
appears but if I change the active window away by clicking, for  
example, on a Finder window, the preferences window disappears. This  
seems to me to be something to do with the active window.

I have tried using makeKeyAndOrderFront_() and  
setLevel_(NSNormalWindowLevel) on the Preferences object but these  
seem to be NSWindow methods and I just get 'Preferences' object has no  
attribute errors.

Am I going wrong somewhere? You can check out the whole project at http://code.google.com/p/gfgain/source/browse/trunk/
