Format content of messageBox

[ChiaoHuang]

Hi ,
I'd like to show some message.
I will set the message to QString class and then show messagebox

Unlucky, it is not what I want in the messagebox.

This is my example code

    char *info[] = {"Apple", "Banana", "Strawberrie", "Grape"};
    char tmp[1024];
    QString s;

    for(int i=0; i<30; i=i+10)
    {
        for(int j=0; j<4; j++)
        {
            sprintf(tmp, "[%2d] %15s = %2d\n", i, info[j], j);
            s.append(tmp);
        }
    }

    qDebug() << s;
    QMessageBox::information(NULL,  "Fruits",  s, QMessageBox::Yes, QMessageBox::Yes);

The result

I want the content of messagebox same as the debug message.
How to do?

Thanks a lot

Use a fixed width /mono spaced font.

@mpergand
I am sorry for the late reply
I am trying it, but it doesn't work.

    msgFont.setStyleHint(QFont::Monospace);
    msg.setFont(msgFont);
    msg.setFixedWidth(1200);
    msg.setText(s);
    msg.setStandardButtons(QMessageBox::Yes);
    msg.exec();

Thanks

@ChiaoHuang
What type/declaration is this msg variable? It does not seem to obey msg.setFixedWidth(1200); either? Originally you used QMessageBox::information() which is static, so what is going on now in your code?

I only know that https://stackoverflow.com/a/22587461/489865 from 2014 claims to work, you could test that (with a suitable combobox populated, or hard-coded value). If it really does not work you could test out HTML font markup, or even QSS/CSS.

@ChiaoHuang
try:

msg.setFont(QFont("courier")); // or monaco or any fixed font name available on your system

or get the default fixed font with:

QFont font=QFontDatabase::systemFont(QFontDatabase::FixedFont);

@ChiaoHuang
I created a "QMessageBox msg" for using Font.
Yes, I don't know why the msg.setFixedWidth(1200) is not working.

Thank you. I think the HTML font markup should work.

@mpergand said in Format content of messageBox:

msg.setFont(QFont("courier"));

Thank you so much
It is working now after I used msg.setFont(QFont("consolas"));
