converting X-Window compound strings

**Wurgl** · 10th March 2013, 08:32

Finally I found a way to decode that string without home-brewed code.

Qt Code:

Switch view

QString Reader::toString(QByteArray const &line)
{
	if(line.indexOf("\033") == -1)
		return QString(line);
 
	XTextProperty tp;
	tp.value = const_cast<unsigned char *>((unsigned char const *)line.data());
	tp.encoding = XInternAtom(QX11Info::display(), "COMPOUND_TEXT", true);
	tp.format = 8;
	tp.nitems = line.length();
 
	char **retList;
	int retListLength = -1;
	int ret = Xutf8TextPropertyToTextList(QX11Info::display(), &tp, &retList, &retListLength);
	if(ret == Success && retListLength == 1) {
		QString s = QString::fromUtf8(*retList);
		free(*retList);
		return s;
	}
â€¦ some more code if there are multiple lines â€¦

QString Reader::toString(QByteArray const &line)
{
	if(line.indexOf("\033") == -1)
		return QString(line);

	XTextProperty tp;
	tp.value = const_cast<unsigned char *>((unsigned char const *)line.data());
	tp.encoding = XInternAtom(QX11Info::display(), "COMPOUND_TEXT", true);
	tp.format = 8;
	tp.nitems = line.length();

	char **retList;
	int retListLength = -1;
	int ret = Xutf8TextPropertyToTextList(QX11Info::display(), &tp, &retList, &retListLength);
	if(ret == Success && retListLength == 1) {
		QString s = QString::fromUtf8(*retList);
		free(*retList);
		return s;
	}
â€¦ some more code if there are multiple lines â€¦
