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

…. Thank you. I’m speechless. I have been fighting with this issue since the last 30-ish hours, and have just thrown the towel a few hours ago. 

Best,
Burak

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

Hi there,

I am building a Qt application called Aether (www.getaether.net). 

For its Mac version, I have run into the problem of Qt not being able to  detect and raise events to Mac’s dock icon clicks. This is an essential and widely used feature on OS X that is completely ignored by Qt, and I want to provide my users this functionality.

I have found a way to do this on C++ here:
http://aksenkin.blogspot.com/2012/02/how-to-handle-click-on-app-icon-in-mac.html

I am using Python, so I need to accomplish it using PyObjC. I have written the following piece of code so far:

@objc.signature('B@:')
def applicationShouldHandleReopen_hasVisibleWindows_(self, sender):
    print('hello!')
    app.onClickOnDock()
    return True

cls = objc.lookUpClass('NSApplication')
appInstance = cls.sharedApplication # I'm doing some real crazy runtime shit there.
#print(cls, appInstance)
delegate = appInstance.definingClass.delegate
delClass = delegate.definingClass
objc.classAddMethods(cls, [applicationShouldHandleReopen_hasVisibleWindows_])

But this has no effect. No method gets triggered, nothing happens. I have little to no C++ knowledge, so I am probably missing a nuance in the translation. Can anyone point me in the right direction?

Regards,
Burak
