Line breaks in tooltip text

mzimmers

Hmm...it doesn't on mine. I can't get a screen capture of the tooltip, but it's one line and is wider than my main widget. I'm running on Windows 10; not sure whether that is the difference...

mrjj

Hmm

alt text

@mzimmers @mrjj:

Stating the help: http://doc.qt.io/qt-5.9/qtooltip.html

"Rich text displayed in a tool tip is implicitly word-wrapped unless specified differently with <p style='white-space:pre'>."

He! Sometimes they are wrong and that makes it even harder :)

@aha_1980 I just used the settooltip() function:

    ui->plainTextEdit->setToolTip("This area contains messages received from the target device. " \
                                  "Currently target debug information is not displayed.");

So is this not wrapping because it's not rich text?

mrjj

Hi
Test indicates that yes

I'm still trying to do this programmatically, but so far without success. Here's my code:

    QString richText = "This area contains messages received from the target device. "\
                       "Currently target debug information is not displayed.";
    QLabel l_toolTip;
    l_toolTip.setText(richText);
    l_toolTip.setTextFormat(Qt::RichText);
    ui->plainTextEdit->setToolTip(l_toolTip.text());

What am I doing wrong here?

@mzimmers
That the text is not rich text.
still just plain text.

To cheat you can use Designer and then grab the code from
setupUI()

~~hmm. Odd using your text, it still dont word break :)~~

@mrjj it is rich text according to the debugger:

    QString richText = "This area contains messages received from the target device. "\
                       "Currently target debug information is not displayed.";
    QLabel l_toolTip;
    l_toolTip.setText(richText);
    enum Qt::TextFormat i = l_toolTip.textFormat();
    qDebug() << i;
    l_toolTip.setTextFormat(Qt::RichText);
    i = l_toolTip.textFormat();
    qDebug() << i;
    ui->plainTextEdit->setToolTip(l_toolTip.text());

I get this:

Qt::TextFormat(AutoText)
Qt::TextFormat(RichText)

mrjj

hi
alt text

Rich text looks like this

<html><head/><body><p>this area contains messages received from the target device. Currently target debug information is not displayed</p></body></html>

I dont think you can just lie to it about the format.

Code from Designer

pushButton->setToolTip(QApplication::translate("MainWindow", "<html><head/><body><p>this area contains messages received from the target device. Currently target debug information is not displayed</p></body></html>", Q_NULLPTR));

mzimmers

@mrjj yeah, you're right...I just discovered that. Somewhat misleading documentation, IMO, but maybe it's just me.

Anyway, this works:

        char myToolTip[] = "<html><head/><body><p>This area contains messages " \
            "received from the target device. " \
            "Currently target debug information is not displayed." \
            "</p></body></html>";
    ui->plainTextEdit->setToolTip(myToolTip);

Thanks to all for the assistance.
