constructing a string using temporaries

[user4592357]

i need a alike method:

QString constructWidgetTitle(const QString &sPrefix, const QString &sWidgetTitle)
{
	return sPrefix + "_" + sWidgetTitle;
}

is this the correct way to do it? or i should use QLatin1String (or what?) for constructing the "_"?

The above is correct (unless you disabled this feature in your project file), using return sPrefix + QLatin1String("_") + sWidgetTitle;, however, is more efficient.

If you have a lot of +s then the best solution is to #include <QStringBuilder> and use % instead of +
