[Qt-interest] icons for files

[Tanguy Krotoff]

Then you can create a temporary file on the local harddrive with the
same extension as the remote file.
This way QFileIconProvider will give you the right icon.

here some code


QIcon fileExtensionIcon(const QString & extension) const {
	static QFileIconProvider iconProvider;

	QIcon icon;

	QTemporaryFile tmpFile(QDir::tempPath() + QDir::separator() +
QCoreApplication::applicationName() + "_XXXXXX." + extension);
	tmpFile.setAutoRemove(false);

	if (tmpFile.open()) {
		QString fileName = tmpFile.fileName();
		tmpFile.write(QByteArray());
		tmpFile.close();

		icon = iconProvider.icon(QFileInfo(fileName));

		tmpFile.remove();
	} else {
		qCritical() << __FUNCTION__ << "Error: couldn't write temporary
file:" << tmpFile.fileName();
	}

	return icon;
}
