    @M-H-H As I said, at least try void QSqlQuery::setForwardOnly(bool forward). With any driver.

    Hi and welcome to devnet, AFAIK, you should not need to do that with QFSM. Making it read/write and activating the drag and drop features of the view should be enough.

    @mrjj sure :). I spot that there is another syntax for the connect function with &. i use: connect(ui->tree,&QWidget::customContextMenuRequested ,this, &MainWindow::showContextMenu); and it works fine. I think you would spot it easy if you would see the whole code. @ManjunathXI thank you already solved!

    @jsulm Absolutely! The threading needs to be addressed. I just wanted to alert you to the other thread, before you spent time trying to answer here.

    @Ayush-Gupta said in Problem using ShowColumn function of TreeView.: QTreeView::resizeColumnToContents(int column) makes my view very slow. Is there any alternative ? Yes, do the column resizing yourself. I said you are responsible for doing so. I only suggested QTreeView::resizeColumnToContents(int column) as a possibility, depending on what you want to achieve.

    Sorry I forgot to replace it. In the original code they are all called networkEditor.

    @kitfox I found a workaround. I ran a different project in debug mode which allowed me to edit the expressions I had entered in the watch window. It would be nice if Qt Creator could handle this gracefully within the original project, though.

    Both QTimer timer and QTimer * timer{} are ok. The only difference is QTimer header file is included or not in the class header file. This is not an issue. If C++ is used, new and delete is not a problem. You do it all day long.
