c++ - Qt Extending my own widget -

-

To put it simply, I want a new class that increases the custom widget I created, and thus There is full access to this UI.

I have tried many different ways till now, how would normally sub-classes / extend classes, but I have in any way been for many reasons I have failed miserably.

In addition, just do not use my widget as a member in my new category for this situation.

Can anyone tell me how do I do this? I've done a bunch of searches but I can not seem to find any hits related to what I'm actually trying to do if everything goes wrong so I'll just copy the code and make a real Create a new widget, which will be technically saved, it takes a lot of time, but it is not doing it properly.

My first trend was to do something like this ( Qwe being my new class, asd widget): 

 < Code> class Q: ASD {public: ...}

And I have also created the U public, but then I just get an error:

< P> UI :: ASD

Use the undefined type whenever I tried to reach the elements of U.

BaseWidget and a child widget named ChildWidget

. Normally declare BaseWidget , but preserve your UI member instead of private, such as: 

  protected: UI :: baseview * UI; Declare as a simple widget generated from   
  ChildWidget  to  BaseWidget . Make sure that you are included in the  ui_BaseWidget.h  file in the  ChildWidget.cpp  file, as you do it in  BaseWidget.cpp  (includes And the header itself is generated by QT). 
 
 Header: 
 
  #include "BaseWidget.h" Category ChildWidget: Public BaseWidget {Q_OBJECT Public: Clear ChildWidget (QString text, QWidget * parent = 0); };  
 
 source: 
 
  #include "ChildWidget.h" ## "ui_BaseWidget.h" ChildWidget :: ChildWidget (QString Text, QWidget * Basic) included Do: Basewitz (Parents) {ui- & gt; Label-> Set text (text); }

I have a form that has a property named car A class with many properties. The Properties is being displayed on the current car on the basis of some user actions that are being displayed. So I have to know whether the property has been allocated or set to zero. I'm aware of INotifyPropertyChanged , but in my case I'm not sure that since this change I have changed my car properties car do not want to monitor the property. Any idea how to accomplish this? In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
