[Pyobjc-dev] Multiple Nibs

[Bob S. <rsw...@tr...>]

I'm trying to set up a second NIB for a modal dialog to display progress
while my application does some processing in my Mac OS X app.  We are using
Python 2.3 with PyObjC 1.1b1.  However, the "magic" that loads the classes
from the NIB file doesn't seem to work for me. (That's the problem with
magic - it is somewhat obscure 8-) ).  My guess is that I'm missing some
important step, but I can't figure out what it is and I don't see an example
that covers this.

In my main application, when it is time to show the modal dialog, I have:

from mymodalpanelclass import MyModalPanel

    def showMyModalPanel(self):
        myModal = MyModalPanel.alloc()
        myModal.init()
        myModal.showDialog(application)
        while <more-work-to-do>:
            <do-some-work>
            myModal.runDialog()
        myModal.closeDialog()

In a secondary NIB file called "MyModalPanel.nib" I created an NSPanel
window, set the class of "File's Owner" to MyModalPanelController, created
an outlet "myModalPanel" and connected it to the NSPanel window.

In the file that implements MyModalPanel, I have:

from PyObjCTools import NibClassBuilder
NibClassBuilder.extractClasses("MyModalPanel")

class MyModalPanelController(NibClassBuilder.AutoBaseClass):
    # the actual base class is NSObject
    # the following outlets are added to the class:
    # myModalPanel

    def showDialog(self, application):
        self.application = application
        self.myModalPanel.setWorksWhenModal(True)
        self._modalSession =
self.application.beginModalSessionForWindow_(self.myModalPanel)

    def closeDialog(self):
        self.application.endModalSession_(self._modalSession)

    def runDialog(self):
        self.application.runModalSession_(self._modalSession)

However, when I run this code, I find that self.myModalPanel is None and of
course, nothing works.  My impression was that the Panel would be created
automatically when I created the MyModalPanelController instance.  What do I
need to do to get the NSPanel created?

Thanks!
