General and Desktop

That works perfect. Thanks a lot!

@filipdns It is not really a Qt question more a SQL question. In SQL you can use triggers for that. See http://www.mysqltutorial.org/create-the-first-trigger-in-mysql.aspx https://sqlite.org/lang_createtrigger.html

@samdol Well since its still possible to style that area of the scrollbar it should be fixable. :) [image: KpQNuz.png]

@6thC cool story, thanks for the detailed reply! I've realized that QLegend isn't the best solution for me, so I ended up doing something similar to what you did. I'm using labels with a monospaced font and splitting the whole and fractional parts, so it's a lot nicer now

@mrjj Thanks, you too.

@Ian-Bray Well if its possible to be a VST compatible app and load such plugins, then it should be possible. Seems to be a standard for plugins.

Hi Nope QProgressBar has only one span. Im not sure how multi range should work but you can maybe group a few QProgressBar in a container and make interface to¨ define the ranges and the min max for each.

Hi I think the rich text used in QTextEdit is still functional in HTML5 http://doc.qt.io/qt-5/richtext-html-subset.html https://stackoverflow.com/questions/134727/whats-the-key-difference-between-html-4-and-html-5 However it seems some elements dropped – center, font, strike but if that will issue is hard to say.

@justStartedQt Super Good work ! \o/ Thank you for posting code. Hehe thank you. If i do not win this year, its a good comfort :)

@VRonin said in Connect model to different views with different display roles: KDescendantsProxyModel Hey, thanks a lot. Using another displayRole in the combo is working fine. However I am still stucking with the data of the top level's children. Since I am using PyQt, I think I cannot use KDE. The last update of PyKDE was in 2013 and I do not find an appropriate wheel for installation. Is there another way with pure Qt (PyQt) components? Thanks Daniel

Hi @tham Yes. I use it e.g. to download files. -Michael.

I tried this. Like this the record will be inserted in the database table, but somehow the table view is not updated correctly. It looks like this [image: daaae09e-b671-4b33-829d-9023b925d755.png] and I cannot edit the record. PS: Thank you for the hint of the database issue.

@ZF__ QAbstractSocket also provides signals bytesAbailable and bytesWritten.. First i suggest you to use qthreads.. networka aa; QThread * td = new Thread; aa.moveToThread(td); td.start(); Create udpsocket in networka and connect signals such as bytesAvailable, disconnected and other signals as below in networka QUDPSocket * udpSocket; // other connection related stuff... Connect(udpSocket,SIGNAL(bytesAvailable()),this,SLOT(readData())); // connect other signals ... implement slot in networka something like void readData(){ QByteArray ary = udpSocket.readAll(); // ary contains all data thats read... } this way you can get rid of while loop and corresponding slots will be connected on respective signals.. i.e., when bytes are available in socket, readData Slot will be called and you read data... PS: signals what i mentioned above may not be exact.. please check documentation for exact syntax.

@Bart_Vandewoestyne Reading the docs, QTime::start() only says: "Sets this time to the current time". So startTime.start() is only doing exactly the same as QTime startTime = QTime::currentTime();. And presumably startTime.elapsed(); is only doing same as QTime::currentTime() - startTime. Hence your code works. For the old code, it's only using startTime, which it assigns, so the stand-alone statement QTime::currentTime(); has no effect. You'd have to ask the author :), but I would presume it was unintended.

@raven-worx said in DBUS_SESSION_BUS_ADDRESS with QDBusConnection: @nxMan said in DBUS_SESSION_BUS_ADDRESS with QDBusConnection: I want to get DBUS_SESSION_BUS_ADDRESS value without checking envs of any process what do you mean with "without checking envs of any process"? I can find pid of a process wich will have DBUS_SESSION_BUS_ADDRESS env variable and obtain the dbus address from its environment. But I don't want this solution.

Why don't you use resize(int w, int h) function instead of setFixedSize(w,h) at the first place?

Hi I just keep a pointer to the "white lines" and adjust if i move yellow. class ColorItem : public QGraphicsItem { .. ConnectorLine* line = nullptr; .. protected: QVariant itemChange(GraphicsItemChange change, const QVariant& value) override { if (change == ItemPositionChange && scene()) { if (line) { line->adjust(); } } return QGraphicsItem::itemChange(change, value); } private: QColor color; }; line->Adjust() alters its endpoints. You could just adjust it directly here.

@jsulm All makes sense now! I had assumed that a normal Qt (X11?) window/dialog would serve as the parent for (what turns out to be a GTK) native file dialog. Now I get the problem, and the reason for the warning!

@CorD-SaC Hi,friend. Welcome. Could you move below code to void MainWindow::showEvent function, try it. QMovie *movie=new QMovie(":/res/icons/giphy.gif"); if (!movie->isValid()) { // Something went wrong :( } ui->labelGif->setMovie(movie); movie->start(); ui->widgetGif->setVisible(true);

@payman i have no experience with accessibility on Linux. But maybe the following helps you: Qt Accessibility is based on AT-SPI via DBus on Unix/X11 and is tested to be working on Gnome and KDE. Are you sure that i3wm even supports accessibility?
