Using std::to_string

[samop]

Hi

Can anyone suggest what's wrong here...

    int lettercount;
    lettercount=strlen("ABC");  
  
    subwin->doco->setPlainText(std::to_string(lettercount));

The second line here is failing to compile with error "/home/laurie/NetBeansProjects/QT_Learning2/QTDesigner/mainwindow.cpp:188: error: no matching function for call to 'QTextEdit::setPlainText(std::string)'
subwin->doco->setPlainText(std::to_string(lettercount));"

The second line works fine if I do something like

subwin->doco->setPlainText("10");

I'm sure I'm missing seomthing simple.

Cheers

Sam

I believe that setPlainText accepts either c-strings (char pointers) or QString and not std::string

which would mean that you need to use subwin->doco->setPlainText(std::to_string(lettercount).c_str());

Hi guys

It worked with

 subwin->doco->setPlainText(QString("You typed %1").arg(lettercount)))

Thanks for the pointers...
