@klynxe said in Update QTreeView on add data to subitem: emit dataChanged(index(i,0), index(i,4)); You are passing the wrong a indexes. Those are 4 columns in the top level, you should pass 1 more argument specifying the parent to each index() call

@SGaist Thank you very much. That was it.

@JonB the NotOpen enum is from QIODevice::OpenModeFlag. I accidentally used it in my switch as QSerialPort::NotOpen (suggested by autocompleter), which compiled ok, but caused this problem.

@qazaq408 You look at the server's QUdpSocket's data receiving methods for this, as they will include the sender's IP address, e.g. http://doc.qt.io/qt-5/qudpsocket.html#readDatagram

Hi, Unrelated to your topic, but I'd recommend not prefixing your custom classes with Q, this will generate confusion for people reading your code (you included) and might clash one day with Qt if they implement a class named like that.

Hi, You should check the bug report system to see if there's something related to that. Also, take look at the documentation to see if there was any change related to that in qbs. WARNING: I haven't use qbs so I might be wrong here: the path you use is a bit surprising, you have "/bin" which is an absolute path. That might mean that you are trying to write to a system library.

@_hunter You're welcome: Link

You can use KArchive's KCompressionDevice to read GZip files: instead of response->readAll() you'll have KCompressionDevice(response,false,KCompressionDevice::GZip).readAll()

@_hunter Hi bascially, you include the needed SO files etc and do #!/bin/bash cd /mnt/xx/theprogfolder export LD_LIBRARY_PATH=./ ./progname its shown in http://doc.qt.io/qt-5/linux-deployment.html section Creating the Application Package This is best used for testing. the rpath way is better for real deployment. or so i have been told.

Perfect, Thanks!

@MECoder said in Sorting of QNetworkInterface::allInterfaces() is different from 1st and 2nd call: Nothing in the docs for QNetworkInterface::allInterfaces() says anything about the order returned, so no reason to expect any kind of sorting (e.g. for all we know the code may report interfaces using asynchronous calls). So sort your combobox by whatever you wish to sort by for your consistency, e.g. perhaps name.

@aha_1980 It works ! Thanks alot :)

Not a temporary table, you can use a QSortFilterProxyModel and then serialise the proxy rather than the original model. Since your current architecture relies on the QStandardItem interface rether than the QAbstractItemModel one you'll need to do some rewriting. To give you an idea, being QString m_csvSeparator the column separator: #include <QStringBuilder> QString escapedCSV(QString unexc) const { if (!unexc.contains(m_csvSeparator)) return unexc; unexc.replace(QLatin1Char('\"'), QStringLiteral("\"\"")); return '\"' % unexc % '\"'; } bool writeCsv(QTextStream& writer, const QAbstractItemModel* constModel) const { if (!constModel) return false; for (int i = 0, maxRow = constModel->rowCount(); i < maxRow ; ++i) { for (int j = 0, maxCol = constModel->columnCount(); j < maxCol ; ++j) { const QString roleData = constModel->index(i, j).data().toString(); if (j>0) writer << m_csvSeparator; if (!roleData.isEmpty()) writer << escapedCSV(roleData); } writer << '\n'; } return writer.status() == QTextStream::Ok; }

@jsulm Stress test. Yes, it need optimization, but i can't find ways to optimize it, 500ms is too large, 200ms is ok...

@Qt-Enthusiast emit the dataChanged() signal (in the model)
