@Pl45m4 said in how to get the wheel event from the qwebenginview widget?: Never mind, the filter is installed on focusProxy() QObject... Yes that was what I was drawing attention to for the OP. I don't know but the SO poster was saying mouse events (including wheel) go to focusProxy().

I still cannot make this work. I have even tried to build Qt 6.7.2 from sources to see and the weatherinfo example just exhibits this problem. Any help is very welcome.

https://github.com/socketio/socket.io-client-cpp/blob/master/INSTALL.md#with-cmake The above link had the detailed info on how to build the socket io for C++ or follow what I have did 1- clone the vcpkg first , because it has all the required modules git clone https://github.com/microsoft/vcpkg.git 2- then run the batch file to make vcpkg to install the required modules .\bootstrap-vcpkg.bat 3- then install the required modules .\vcpkg install boost-asio boost-system boost-random websocketpp openssl 4- then get the code for socketio cpp git clone --recurse-submodules https://github.com/socketio/socket.io-client-cpp.git 5- make the build structures mkdir build cd build 6 then CMAKE it cmake -G "Visual Studio 15 2017" -A x64 -DSIO_TLS=ON . 7 then build it cmake --build . --config Debug

I solved the issue by changing INCLUDEPATH += /include to INCLUDEPATH += /absolute/path/of/include for both INCLUDEPATH and LIBS.

Alright, thank you.

I guess you are under windows? That's the default behavior for windows gui application. You'll need to add win32:CONFIG += console to the pro file if you are using qmake. But then there will be another problem, if you start the application from console/terminal, it is ok, but when you double click the exe, there will also be a console window which probably you dont want. So why you need std::cout in a gui application in the first place?

I also encountered this problem, can anyone solve it?

@JonB Thank you.

Why sorry ? This a good question and can inspire other people to do the same and contribute :-) As for marking the thread as solved, you can do it. Either use the topic tools button (the cog button) or the three dotted menu beside the answer you deem correct.

@gfxx I correct into: /* other code */ private: friend class QDragManager; Q_DISABLE_COPY(QDrag) }

@nicker-player said in how to make the widget shadow with the qss style.: QWidget::shadow There is neither a pseudo-state nor a sub-control with this name... Either it's a custom styled property or your "source" was talking bullsh*t :) QFrame::Shadow does exist for QFrame-based widgets. https://doc.qt.io/qt-6/qframe.html#Shadow-enum Or look into QGraphicsDropShadowEffect (this was probably used in combination with the shadow property to configure it via stylesheet)

@KevinAR said in QT Designer: Push Button Error: I think I find the cause of this problem when I use a background with a JPG file. It causes the button to become transparent. However, when I don’t use the background, the button still appears. Your assumptions might be wrong here. How do you set the background for your widget/app? Note: if you go QWidget { background-image: "someImage"; } your QPushButton will also inherit the stylesheet... maybe that's why you think it's transparent.

I've already got the code to calculate bezier curves and gaussian curves, so they can be handled as line charts.

@Axel-Spoerl how can i do that? and What's wrong if I want to compile all things statically؟

Hi, You might want to check projects such as LXQt that provides a desktop environment built on Qt for inspiration.

So, on high-DPI displays, the toolbars get padded a TON, and this doesn't happen on normal res displays, so I had code that iterates over all the buttons and sets them to a fixed size. This apparently breaks the centering on buttons that didn't come from actions. I'm not sure exactly what the difference is, but I've changed my code to do this: static void FixHighDPIButtonSpacing( QToolBar * pBar, int baseSize ) { int horizPad = 2; int vertPad = (pBar->orientation() == Qt::Vertical) ? 0 : 5; const QObjectList & list = pBar->children(); for( QObject * obj : list ) { QToolButton * btn = dynamic_cast<QToolButton *>(obj); if( btn != nullptr ) { if( btn->metaObject() != &MultiActionButton::staticMetaObject ) { btn->setFixedSize( baseSize + horizPad, baseSize + vertPad ); } } } } ... and now it works. It has extra padding above & below compared to the buttons around it, but that's a fight for another day. [image: 1b95cc61-0e42-4f1b-8a6f-e95dc73c9420.png]
