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...

(URL_DEFINED) Print Rustusodod Soup = Beautiful Soup (Rtext) Print soup.fund_all ('ul') What I found: Tracebacks (Most recent call end): File "scraper.py", line 1 9, & lt; Module & gt; Print soup.find_all ('ul') TypeError: The 'NoneType' object is not worth the corner It seems that you are using Sundersup version 3, in which a slightly different naming convention is used, such as: .findAll , while SunderSupo 4 standardized naming, like more PEP8, Such as: .find_all (but retains the old naming for previous compatibility) Note that soup ('ul') is equal to both search for all . To download and install, install pipes PrettySpeed ​​4 . Then to change your import: import from bs4 BeautifulSoup Then you are good go.
