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!
