python - How to propagate changes from child widgets if any of the child have changes? -


मेरे पास एक QWidget है। और QWidget के अंदर, मेरे पास बहुत से अन्य QWidget s, जैसे: - QComboBox , QLineEdit , आदि ....

अब, मैं जानना चाहता हूं कि उपयोगकर्ता ने कोई भी परिवर्तन किया है ( उदा: - QLineEdit में कुछ लिखें, या < कोड> QComboBox , आदि .... ।)

क्या ऐसा करने का एक आसान तरीका है? या मुझे प्रत्येक विजेट के सिग्नल पर कब्जा करने की आवश्यकता है, जैसे ... 

  QObject.connect (लाइनएडिट, सिग्नल ("टेक्स्टवर्ल्ड ()"), doSomething) QObject.connect (कॉम्बोबॉक्स, सिग्नल ("वर्तमान इंडेक्स चेंगड (इंट)"), डॉट्सिंग) ... ... ...    
 
 
 हाँ, आपको मैन्युअल रूप से संकेतों को कनेक्ट करना है।

asp.net - MVC [HandleError] HandleErrorAttribute called twice when using global logging -

For a particular view, I also wanted to display a different error view, if by decorating the method with [HandleError (View = "SpecialError")] Unwanted exceptions occurred. It works fine. Then I want to add global logging to unsociable exceptions. I created a custom handle error feature with the logging code: Public class MyHandleErrorAttribute: HandleErrorAttribute {The public override zero over exponence (exception context context) {// code to log code code. Xxation (reference); }} And instead of using this attribute name, register global filter and method decoration has been updated. It usually works, but when there is an exception method that is decorated with MyHandleError (see = "special error...
