QML and Qt Quick

@LeLev and thx for fast response on an old topic :) I just tried it and it does what I need I'm pretty new to Qt. So much to learn. Cheers

@mirro said in Why is this 'keyValueList.push(KeyValue{})' code syntax incorrect in qml?: But I don't understand why you can't just assign values but use temporary variables instead? you can, but be aware of https://doc.qt.io/qt-5/qml-variant.html#storing-arrays-and-objects Additionally, since items and attributes are not QML objects, changing the values they contain does not trigger property change notifications. If the above example had onItemsChanged or onAttributesChanged signal handlers, they would not be called when assigning individual entries in either property. If, however, the items or attributes properties themselves were reassigned to different values, then such handlers would be called. @mirro said in Why is this 'keyValueList.push(KeyValue{})' code syntax incorrect in qml?: Also, do I need to free memory in this 'Component.onDestruction'? AFAIK no, because there is automatic garbage collection

I think you should use PathView instead of SwipeView, since the first one is originally intended for your purposes.

Thanks. Problem solved. In code I had line var number = "" and I put this variable as parameter into function.

I thinks solution is Connections. It's work. ColorOverlay { id: favIconOverlay anchors.fill: favIcon source: favIcon color: getColorCode(id) transform: rotation antialiasing: true Connections { target: favoriteModel function onCountChanged(foo) { var newColor = getColorCode(id) if(newColor === '#ed670e') { favIcon.isFav = true } else { favIcon.isFav = false } favIconOverlay.color = newColor } } }

Below full code of Menu with adding and reading menuitem Menu { id: submenuAlarms title: "Alarms" function createMenuItemDefault() { var defaultAlarms = ["30s", "1m", "3m", "5m", "10m", "20m", "30m", "1h"]; var numberOfAlarms = defaultAlarms.length var alarmsItems = [numberOfAlarms]; var index = 0 for (var alarm of defaultAlarms) { console.log(alarm) var item = submenuAlarms.addItem(alarm) item.id = "ID_"+alarm item.triggered.connect(function(){console.log("Value: " + alarmsItems[__selectedIndex])}) alarmsItems[index] = item.text index++ } return alarmsItems } Component.onCompleted: { createMenuItemDefault() } }

I'm not sure if I understand things with total clarity. However, if I understand, then these both exist in a base class: /* (1) */ Q_INVOKABLE void saveToFile(QUrl url) {saveToFile(url.toLocalFile())}; /* (2) */ Q_INVOKABLE virtual void saveToFile(QString string) = 0; And some QML code is triggering entry/execution into (2) instead of (1). In that case, I wonder why not just remove Q_INVOKABLE from (2) so that it is not-invokable from QML?

hi @NullByte said in Qt Quick Websocket and Listview: Can we update the Listview instantly by QML? Yes, add whatever you want to you ListModel using append method

Each graphical effect is a separate component, you can combine as many of them as you want. If you need to blend them, use Blend component.

hi @Designer23 said in Open folder on computer QML: filedia.setFolder("D:/Users/hp/Doc") I dont see setFolder() mthod here https://doc.qt.io/qt-5/qml-qtquick-dialogs-filedialog.html#methods maybe try filedia.folder = "D:/Users/hp/Doc"

I'm sending also printscreen: [image: 5024d9ca-a876-49b6-9d07-5cae564b22dc.png]

Hello! I think what is missing is a specification of the contentWidth and contentHeight of the ScrollView. The reason this breaks in the main case is because ColumnLayout has no default width/height. In spite of your specification of an implicitHeight and implicitWidth the ScrollView still must have the content sizes specified manually. So adding: contentWidth: parent.width contentHeight: the_column.height to the ScrollView resolves the issues.

Deploying this code on Windows doesn't change the situation, just checked this out.

I found this link useful.

hi You use "play" as property name and button id
