Yes, you can have many return points.

And reffering to lineEdit's text, here's quote from docs:

This property holds the line edit's text.

Setting this property clears the selection, clears the undo/redo history, moves the cursor to the end of the line and resets the modified property to false. The text is not validated when inserted with setText().

The text is truncated to maxLength() length.

Access functions:

*
QString text () const
*
void setText ( const QString & )

See also insert() and clear().

access functions doesn't say how to refer to lineEdit's text. QString text () const it's just a declaration of a string. void setText ( const QString & ) is to set the lineEdit's text. And I still don't know how to operate on lineEdit's text.

access functions doesn't say how to refer to lineEdit's text.

Hmm? Do you know the meaning of the word "access"?

QString text () const it's just a declaration of a string.

Hmm?

It's a declaration of a function/method that is called "text", returns a "QString" object and takes no arguments (implicit void).

void setText ( const QString & ) is to set the lineEdit's text.

Correct.

And I still don't know how to operate on lineEdit's text.

How about just trying to use the "text()" method?

[Salazaar]

Is something like this correct?

QString text (lineEdit) const

QString text (lineEdit) const

To copy to clipboard, switch view to plain text mode 

is that the "text method"?

[wysota]

No, it doesn't make any sense.

QLineEdit *myEdit;
//...
QString xxx = myEdit->text();

QLineEdit *myEdit;
//...
QString xxx = myEdit->text();

To copy to clipboard, switch view to plain text mode 

Please learn a bit of C++...

Thanks, now's clear. And if in lineEdit is an integer, I should use int (quint) instead of QString, right?
edit:
this problem wasn't about my c++ skills, but logical methods, I had no idea about it

No. if lineEdit is an integer then it already holds its own value.

A lame excuse is better than no excuse...

[Salazaar]

But text can be an integer. So how can I operate on integers which are in lineEdit?

Search QString docs and pick a method that converts the string to int.

Thanks, I'll read it
