मेरा ऑब्जेक्ट 

  आइटम {property int current: 0}   
 क्या यह एक सिग्नल फेंकने के लिए कॉन्फ़िगर किया जा सकता है, जो निम्न कार्य करता है?  
  आइटम {संपत्ति के संस्करण myObj: MyObject {} पर MyObjChanged: doThis () ..}    
 
 
 cmannet85 ने आपके प्रश्न का उत्तर दिया है: यह संभव नहीं है। शायद आप अधिक कोड पोस्ट कर सकते हैं ताकि हम वैकल्पिक तरीकों का सुझाव दे सकें।  
 आपके द्वारा प्रदान की गई जानकारी का उपयोग करते हुए एक समाधान के संदर्भ में, आपको उस संकेतों का पर्दाफाश करना चाहिए जो क्लाइंट कोड ऑब्जेक्ट बदल गया है। चूंकि आपने कहा है कि  current  संपत्ति सभी मामलों है, और यह, आप  कनेक्शन :  
  कनेक्शनों का उपयोग कर सकते हैं {लक्ष्य: myObj onCurrentChanged: DoThis ()}   
 या मैन्युअल रूप से सिग्नल से कनेक्ट करें:  
  Component.onCompleted: {myObj.onCurrentChanged.connect (doThis); } फ़ंक्शन doThis () {// ...}

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
