My Qt application should open a html page (with the default browser eg. IE). This html code is stored in a QString.

What would be the best way to open this “file”, of which I only have the content?

Is QTemporaryFile the answer to this? Or could this be done easier?

QString content = "<html>...</html>";
?
QDesktopServices::openUrl(QUrl("..."));

    The QTemporaryFile approach is by far the easiest to accomplish your task.

    I don’t see any other way other then doing some “vodoo” with ActiveQt, if that works at all.

    Best regards.

    EDIT: An example

    QString htmlData; // your HTML data here

// The six Xs are actually required.
QTemporaryFile tmpFile( QLatin1String( "thefileXXXXXX.html" ) );
tmpFile.open();
QTextStream out( &tmpFile )
out << htmlData;
tmpFile.close();
QDesktopServives::openUrl( QUrl::fromLocalFile( tmpFile.fileName() ) );
