Simplest possible scrollable text box (C++)

StringTheory

Very simple requirements:

Add plain ASCII text to box
Allow scrolling with scrollbars if number of lines or columns exceeds displayed area

"Would also be nice" (but not imperative):

Capture text to clipboard via mouse-click-drag-highlight
Print all text in textbox

The former is really the main thing, as I'm really just using this as a status display. I don't need editing. I thought there would be a simple Qt example somewhere...?

PS: I'm still running into the infamous 'connection bug' when trying to access this forum via some machines.

Hi,
can you check if QTextEdit is suitable ?

#include <QApplication>
#include <QTextEdit>
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    QTextEdit *txt = new QTextEdit();
     txt->setText("Hello, world!");

     for(int i(0);i<100;i++){
       txt->append(QString("adding line :  %1").arg(i));
     }
     txt->show();
    return a.exec();
}

Hi
A simple version would be to place
QScrollArea + layout + QLabel
and for QLabel sets its Text interaction to allow mouse text selection.

alt text

Add plain ASCII text to box
setText will handle that
Allow scrolling with scrollbars if number of lines or columns exceeds displayed area
QScrollArea handles that
Capture text to clipboard via mouse-click-drag-highlight
TextInteraction flags allows text to be selected. you have to right click and select copy to go to clipboard.
Print all text in textbox
that you have to do by hand with QPrinter and friends.

Two excellent replies. I'll try them and get back if there are any remaining questions.
Thanks!
