@Ashish_Pathak said in Weather API in qml: I did check out for weather api's online So, what did you find?

@Babitha They link to their Qt repository - so use it if you want the Qt version used for wkhtmltopdf - as you can see it's a Qt4 repo with some patches from them.

This is example how to use Qt::UniqueConnection

@SimonSchroeder The reason I use show ()/hide() for pics is that in my actual project, each picture has a different display duration. For example, if there are three pictures in total, initially they are all displayed. After 1 second, the first picture is hidden. After 2 seconds, the second picture is hidden. After 3 seconds, the third picture is hidden, and then it switches to the next set of pictures.

@Pl45m4 I just fished the task adding menu and submenu. I could post the code , but it is still "under construction". My main misunderstanding was the relation between menu and action.

Hi @ks-zealot, I could solve this in QT6 using QVideoSink, however, CPU usage is quite high. My main issue being that I need to memcpy a custom buffer to QVideoframe. I am willing to help/exchange on this though. Could you make progress on your end yet?

@SGaist: After another look at my code, i found the error: The width of the QTableViews rectangle was too big. Thanks for your help, anyway. Kind regards, Andreas

As I understand it, the child should receive the event before the parent, but in my case, the child is deaf. I thought maybe the problem was the size of the child, so I set it equal to the parent size, but it didn't help. I can call mousePressEvent(e) directly for the child in the parent's overload, but it looks like a very bad design. UPD: currentPrimitive_->setKeepMouseGrab(true); allows to pass the event to the child without ugly direct call of mousePressEvent(e) .

@jsulm said in QTcpSocket always connectingState: If you really want to do that then you have to make sure the QTcpSocket instance is created in another thread (when CenterManageSystem::main is called). Sure, the instance will be created in &CenterManageSystem::main. Because this socket will process much data so I move it to another thread then the data can be sent by signal to update UI.

@Brian_H Add https://doc.qt.io/qt-6/qboxlayout.html#addStretch to your vertical layout at the bottom

Good morning, The documentation isn't clear about which platforms are supported wrt captive portal detection. It's supported for Android, Glib, Networkmanager (DBus) and Networklistmanager (on Windows, if QT_FEATURE_networklistmanager is enabled). Detection support for Apple platforms hasn't been implemented (yet). That's why it returns falsealways. Cheers Axel

Thanks @ChrisW67 Stupid mistake.

@Wugge said in Problem with stretching QGridLayout: It should only take up as much space as it needs for the buttons and title to fit. If I scale the window and the buttons don't fit in the row anymore, they should go to the next row and the area should stretch with it. like this? https://doc.qt.io/qt-6/qtwidgets-layouts-flowlayout-example.html

@Pl45m4 Thanks, it is so stupidly simple... I do not get why the examples are so complicated... Oh well - one problem solved Many thanks.

@marius-thorre Please mark the topic as "solved" if you dont have further questions and your issue got resolved.

@Joachim-W said in setStyleSheet for QToolBar::separator?: Anything wrong here? Yes, the separator stylesheet. ::separator is a sub-control of QToolBar and therefore can't put next to the general properties of QToolBar, like border-left. It needs its own container. setStylesheet("QToolBar {border-left:1px solid rgb(180,180,180);} ::separator{background:yellow; height:80px; };");

@qcoderpro Btw: Dear ImGui is even used in Qt (some 3D modules) as 3rd party lib. https://doc.qt.io/qt-6/qt3d-index.html#licenses-and-attributions

Re: Raspberry Pi 4 cross compile trouble The problem solved in another way - seems that we now have to use CMake instead of QMake for qt based crossplatform solutions for arm. So I just made CMakeLists.txt - configured my project again and everything get working. Of course that was painful for a bit (never used cmake before) but you always need to go further and to learn instantly.

@kkoehne Thanks a lot!
