[Qt-interest] QStaticText class and multiline text

[Atlant Schmidt]

Constantin:

  HTML formatting should work, no?

  So use <br/> tags in place of your \n characters.



  http://doc.trolltech.com/4.7-snapshot/qstatictext.html

    For extra convenience, it is possible to apply formatting
    to the text using the HTML subset supported by QTextDocument
    QStaticText will attempt to guess the format of the input
    text using Qt::mightBeRichText(), and interpret it as rich
    text if this function returns true. To force QStaticText to
    display its contents as either plain text or rich text, use
    the function QStaticText::setTextFormat() and pass in,
    respectively, Qt::PlainText and Qt::RichText.

Subject: [Qt-interest] QStaticText class and multiline text

Hi!

I have an application that works with data shown to the user in the form of flowcharts. Since these flowcharts contain relatively high amount of text and that text doesn't change too often, I thought using QStaticText could improve application's performance (currently text is drawn by QPainter::drawText() and I haven't had any performance-related problems so far). But when I tried to use it, I discovered that QStaticText doesn't [seem to] support text with explicit linebreaks and draws empty squares in place of '\n' characters.

Is this a bug or intended behavior? Are there any plans to add support of multiline text to QStaticText and QPainter::drawStaticText()?

I use Qt 4.7.0 RC1 at the moment, if that's important.
