Re: [Pyobjc-dev] how to add methods to this class in this case?

[Robert K. <rob...@gm...>]

Hi Burak,

The signature of that specific method is different:
applicationShouldHandleReopen:hasVisibleWindows:
Sent by the application to the delegate prior to default behavior to reopen (rapp) AppleEvents.

- (BOOL)applicationShouldHandleReopen:(NSApplication *)theApplication hasVisibleWindows:(BOOL)flag
(full documentation here)

Here's a minimal example that works for me:
#!/usr/bin/env python

from    AppKit      import NSObject, NSApplication
from    Foundation  import NSLog
import  objc

class TestApp(NSObject):

    @objc.signature('B@:#B')
    def applicationShouldHandleReopen_hasVisibleWindows_(self, app, flag):
        NSLog('Hello!')
        return True

    def applicationDidFinishLaunching_(self, notification):
        NSLog('App running')

if __name__ == '__main__':
    sharedapp   = NSApplication.sharedApplication()
    testapp     = TestApp.alloc().init()
    sharedapp.setDelegate_(testapp)
    sharedapp.run()


Regards,
Robert
