General and Desktop

It is a bug: https://bugreports.qt.io/browse/QTBUG-86736

Hi, The first step is to get the winId of your external application then use QWindow::fromWinId and finally QWidget::createWindowContainer.

Even so, if you read the description of the format, the A channel is locked at 0xFF.

Video example of what I am talking about. What I want to do, is when I append text to a formatted string it does not extent. Meaning, I should be getting following result: "this is an examplethis is not a desirable result string". Formatting in my program is not a regular bold; it has a lot of stuff going with it.

Hi @J-Hilk, thanks for your answer. I'll just change the variables from MainWidnow.

@VRonin It worked. Thank you very much for the solution.

@Aijaz said in QTcpService based server-clint: connect(ui->m_pClientsocket, &error::SocketError, ui->this, &displayError::SocketError); For syntax please read New Signal Slot Syntax. Probably more like connect(ui->m_pClientsocket, &QAbstractSocket:::errorOccurred, this, &Dialog:::displayError);

Maybe a concrete example of what you want to achieve would be good here. From your initial post I was thinking you needed QConcatenateTablesProxyModel but now I'm confused

From the looks of the patch, you should be able to port it to 5.12 and build the module yourself with it.

This is definitely a very tricky problem. From my experience this is my understanding of how Qt works: Whenever you request the size of a widget (minimumSize() in your case) it does not do a recomputation. There are several methods that should actually recompute the layout, but they never help. I guess the best way is to first call update() to redraw the widget and recompute the layouts. However, you cannot immediately call this->resize(minimumSize()) after calling update() because the update gets delayed. This means that you also have to put the resize into the event loop (and hopefully it gets called after the update): update(); QMetaObject::invokeMethod(qApp, [=](){ resize(minimumSize()); }); If update() doesn't work, you can carefully try to call redraw() instead. The difference is that redraw is executed directly and update is queued into the event loop and update will also merge multiple update events. If used carelessly you can easily destroy the performance of your app when calling redraw.

Hi, @Swati777999 said in Providing image to icons without QLabel and ui: isChecked() What is MyWidget's base class ? If it's just QWidget then it does not have a isChecked method as the error tells you. What exactly is your goal with MyWidget ?

@Sergey-I said in Ctrl-Click not working: Exactly same problem for me. Quite a small project but uses Boost lib which is definitely a huge lib. So ctrl+click takes ages to go to an identifier but F2 works just fine. Without Boost everything works fine. Same at my project: before adding boost everything worked good, but now ctrl-click redirecting takes about 5-10 seconds.

Compile and link your library with Qt 5.6.

@jsulm I think the same, but I wanted to make sure :)

as @eyllanesc mentioned.. you need to define your slot in the header first. means: private slots: void readData(); And do the functionality in the source file.

You can find the solution here. That works for me great!
