c++ - How to declare Qt::PenStyle in Qt5? -


I am migrating a project from QT 4.x to 5, and a class that has a feature that is : 

  Qt :: penstyle penstyle;   
 and its related functions:  
  Qt :: Penstyle Paenstyle () {return penStyle;}   
 There is a compilation error saying that  
  error: 'QVariant :: QVariant (Qt :: PenStyle)' Private QVariant (Qt :: PenStyle) Q_DECL_EQ_DELETE; ^ .. \ marssies \ painterbar.cpp: 217: 88: Error: Style within this Reference Line - & gt; SetCurrentIndex (lineStyle -> SearchData (graphic object-> GetPenStyle ())); ^   
 Some research has shown me:  
 
 QVariant: 
 * Incompatible Constructor Qt :: GlobalColor and QVariant (QColor) Examples Production of removed. The code that creates such forms can be migrated by calling the QColor constructor explicitly. For example, QVariant (QColor (Qt :: red)) from "QVariant" (Qt :: red)  
 * Similarly, the built-in QVariants of built-in QV :: BrushStyle, Qt :: PenStyle , And Qt :: CursorShape has been removed. Obviously create objects or use static_cast (Qt :: SolidLine), in which QVariant with the same value as the AQ value.   
 The question is,  how should I declare attribute / function  if I can not do QT :: as soon as the penstyle?  What does it mean by creating objects clearly?  I have tried to do something like a bid, but I did not manage to solve it. I managed to solve other similar errors, but none of them was announcing the features or functions.  
 Complete error:  
  is included in the file .. .. \. \ .. \ Qt5 \ 5.2.1 \ mingw48_32 \ include \ QtCore / qsettings.h: 46: 0, from .. \. \ .. \ .. \ .. \ Qt5 \ 5.2.1 \ Mingw48_32 \ Include \ QtCore / QSettings: 1, from .. \ mararsies \ appcommon.h: 10, from \ mararsies \ painterbar.h: 5, from \ mararsies \ painterbar.cpp: 1: .. \. . \. \. \ .. \ .. \ Qt5 \ 5.2.1 \ mingw48_32 \ include / QtCore / qvariant.h: member function 'zero painterbar :: setgraphic object (GraphicsPrintive *, Painterbar :: FinishModa)' in: .. \ .. \ .. \ .. \ .. \ Qt5 \ 5.2.1 \ mingw48_32 \ include / QtCore / qvariant.h: 482: 5: Error: 'QVariant :: QVariant (Qt :: PenStyle)' private QVariant is QT :: Penstyle) Q_DECL_EQ_DELETE; ^ .. \ marssies \ painterbar.cpp: 217: 88: Error: Style within this Reference Line - & gt; SetCurrentIndex (lineStyle -> SearchData (Graphic Object-> GetPenStyle ()); The problem is that the enums are a bit of a difficult type and looks like QT5;    
 
 
 The first solution proposed in the docs is to instantiate the object because it is easy to hold a "normal" type in a QVariant from an enum QColor, QPen etc. All QObjects are so general logic to keep them in a QVariant Works for them; It does not work for Qt :: PenStyle.  
 The second solution is then a special C-style solution that uses when working with Iman. As an enum is stored in an int, you can always be explicitly inserted at int (and also C), it never puts it where C ++ is not, afaik). So what is effectively stored in QVariant is an int and you, the programmer is the only one who really knows that this is a QT :: penstyle.  
 While the first solution is a little less efficient, stored thousands of QPen objects instead of QPenStyles / ints), this can be cleaner, because the vocabulary (QVariant holds a pen that you can drag).  
 If this does not work you can:  
  int getPenStyle () {return (int) penStyle;}   
 or < / P> 
  QPen getPenStyle () {Return QPen (penStyle);}   
 Then go ahead and post a self-contained example so that we can discuss more.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
