5 QlineEdits - 1 Button => How to copy text with less steps?

[Lykurg]

I would go for one line edit one button. That is the most intuitive approach. And you don't need to use sender or something like that for it. Just make your own widget containing the line edit and the button. In your main application just create x times that custom widget.

["BumbleBee"]

How can I create that widget?
And also lets say I have lineE1 + btn1 and the button copies text from lE1.
If I paste the widget some times,the name remain same,so everything will be upside-down..or?

[Lykurg]

Create it by subclass QWidget. And as for the number, just introduce a private member with a setter function.

["BumbleBee"]

How can I also double click the text inside and it copies?

[Lykurg]

Just reimplement the double click event handler of the line edit.

Can I have some more info(maybe examples) on QWidget subclassing?
Thanks

[Lykurg]

The examples are full of subclassed widgets. If you make a new application your main class is a subclass of QMainWindow...

class MyClass : public QWidget 
{
  Q_OBJECT
  public:
  //...
};

class MyClass : public QWidget 
{
  Q_OBJECT
  public:
  //...
};

To copy to clipboard, switch view to plain text mode
