General and Desktop

It was a great help for running threads. Running in QtConcurrent::run([=], really solved all the issues of my UI non responsive ness.. Thanks a lot for your help

@markolino_it Then please mark the topic as solved.

@overfl0w said in qt.qpa.xcb: could not connect to display: which is still ROOT privilege uid/gid of 0), it fails about the 3rd of 4th plugin loading (XCB) Usually, root cannot access X server when running from other user account. Do you really have to start your app as root? Regarding plug-ins: set QT_DEBUG_PLUGINS=1 in a terminal and start your app there: there should be much more output providing more details why exactly the plug-in isn't loaded, please post it.

Hi, If memory serves well, you should do that to the widget inside the QDockWidget.

@SGaist , I think the actual problem was low resources ( disk space ), I've cleaned up and removed a lot of junk, now installing again.

Ok it works! In the constructor: positionsForm::positionsForm(QSqlRelationalTableModel *parentmodel, QWidget *parent) : QDialog(parent), ui(new Ui::positionsForm) this->parentmodel = parentmodel; connect(ui->positionsTable->model(), SIGNAL(dataChanged(QModelIndex,QModelIndex)), this, SLOT(updateParent())); And the function: void positionsForm::updateParent(){ qDebug() << "updateParent called!!"; this->parentmodel->select(); }

Looks likes there might be a bug that has crept in. I have a related but different issue with the macOS style.

Are you sure that it is not just related to the fact that you are at the far left of the tab list ? The same happens with macOS. The left button is transparent but as soon as you start moving the tabs with the right arrow, the left one fully appears and becomes usable. It becomes again transparent when full left is reached again.

Did you saw this updated version of the example code you likely used for your application: https://appfluence.com/productivity/how-to-authenticate-qt-google-sso/ ?

@RiccardoTurati Could use mapFromGlobal.

@SGaist , yes, seen it

Seems like the problem was only for Pie, cause Candlestick, Bar and Line had no problem. In Mainwindow the declaration was for: QGridLayout mainLayout=new QGridLayout(); and redefining for the PieSeries isn't a good thing. Thank you QT Charts for being totally poor in explanation in everything and the debugger was telling something completely different from the actual thing. So deleting mainLayout = new QGridLayout; as a line solves the problem. For the poor people who desperately won't find a solution, this was it. The layout.

@SGaist said in Error: no matching member function for call to 'addTab' qtabwidget: Where did you add: #include <QHelpIndexWidget> ? You are so RIGHT!!! I had not added this at all! I had added only "qhelpcontentwidget.h". Now it compiles and works ok!!...almost... I get some irrelevant (??) message (in the application output in Qt Creator) when I open the help window: QSqlDatabasePrivate::removeDatabase: connection 'QHelpCollectionHandler-281628994016-2' is still in use, all queries will cease to work.

@raven-worx Thanks a lot for the quick response! I'll look into it.

Okay, got it. Per this StackExchange answer, and this Qt page, the following is an accepted way to do what I need: onSetModule: lblMsg => modFinder.setModule(lblMsg) Anyway, it works and clears up the warnings.
