@vinaygopal you could customise your Spinbox and set your own TextInput, that one still has the selectByMouse, even if 5.15.8 https://doc.qt.io/qt-5/qtquickcontrols2-customize.html#customizing-spinbox https://doc.qt.io/qt-5/qml-qtquick-textinput.html#selectByMouse-prop

@raven-worx , is there a way to use setContextProperty with auto-completion feature?

@paulmasri said in Qt 6.2 + CMake + extending QML with a C++ class: I am building a standalone app (executable), so I think that what I'm after is a statically linked plugin. I don't believe so. If you're building a 'bundle-all' executable, you wouldn't need a plugin to begin with. I'd try something like this: qt_add_qml_module(People URI People VERSION 1.0 STATIC SOURCES Person.h Person.cpp NO_PLUGIN OUTPUT_TARGETS PEOPLE_DEPS ) target_link_library(myproject PRIVATE People ${PEOPLE_DEPS}) Also you may need to initialize the resources manually, as static builds are pita to begin with. Personally, I wouldn't do it. PS. Also remove the duplicating source files: qt_add_executable(myproject main.cpp Person.h Person.cpp #< Remove this )

After looking for a while, I finally came across these two functions: mapToItem and mapFromItem. So, I first need to map the current item point to the map item coordinate system. Then, I must check the point is inside the map viewport. If not, I have to adjust the coordinate, and after that, I map the point back to the current item coordinate system. Popup width and height seem to decrease when approaching bottom and right borders, so I had to use contentHeight, contentWidth and padding properties to get the real popup size. And I had to initialize the popup x and y to a value different of zero to allow mouse event to pass on the blue dot. Here is the working code, for those who may need it. import QtQuick 2.11 import QtQuick.Controls 2.4 import QtLocation 5.11 import QtPositioning 5.11 import QtQuick.Window 2.11 Window { id: root; width: 800; height: 600; Plugin { id: mapPlugin; name: "osm"; } ListModel { id: myModel ListElement { latitude: 48.2351164; longitude: 6.8986936; name: "The point on the center"; } ListElement { latitude: 48.235111272600186; longitude: 6.9007217756551995; name: "The point on the right"; } ListElement { latitude: 48.23512783507458; longitude: 6.896574932520792; name: "The point on the left"; } ListElement { latitude: 48.23614708436043; longitude: 6.898623901851295; name: "The point on the top"; } ListElement { latitude: 48.23417574713512; longitude: 6.898641104398024; name: "The point on the bottom"; } } Map { id: map anchors.fill: parent plugin: mapPlugin center: QtPositioning.coordinate(48.2351164, 6.8986936) zoomLevel: 19 MapItemView { model: myModel delegate: MapQuickItem { anchorPoint.x: myRect.width / 2 anchorPoint.y: myRect.height / 2 width: myRect.width height: myRect.height coordinate: QtPositioning.coordinate(model.latitude, model.longitude) sourceItem: Rectangle { id: myRect readonly property int radius: 10 width: radius * 2 height: radius * 2 color: "transparent" Canvas { id: myCanvas anchors.fill: parent property alias textVisible: myPopup.visible onPaint: { var width = myRect.width; var height = myRect.height; var centreX = width / 2; var centreY = height / 2; var ctx = getContext("2d"); ctx.reset(); ctx.fillStyle = "blue"; ctx.globalAlpha = 1; ctx.beginPath(); ctx.moveTo(centreX, centreY); ctx.arc(centreX, centreY, myRect.radius, 0, Math.PI * 2, false); ctx.closePath(); ctx.fill(); } MouseArea { x: 0; y: 0; width: myRect.radius * 2 height: myRect.radius * 2 acceptedButtons: Qt.LeftButton hoverEnabled: true onPositionChanged: { myCanvas.textVisible = true; // absolute position in map coordinate system var absPos = mapToItem(map, mouse.x, mouse.y); // margin between mouse pointer and the popup var cursorMargin = 10; // extra margin for right and bottom side var bottomRightSideExtraMargin = 10; // add the cursor margin to the position var absPopupX = absPos.x + cursorMargin; var absPopupY = absPos.y + cursorMargin; // adjust if the popup is out of view on the bottom or right sides if (absPos.x + myPopup.contentWidth + myPopup.leftPadding + myRect.radius * 2 + bottomRightSideExtraMargin > root.width) { absPopupX = root.width - (myPopup.contentWidth + myPopup.leftPadding + cursorMargin + bottomRightSideExtraMargin); } if (absPos.y + myPopup.contentHeight + myPopup.topPadding + myRect.radius * 2 + bottomRightSideExtraMargin > root.height) { absPopupY = root.height - (myPopup.contentHeight + myPopup.topPadding + cursorMargin + bottomRightSideExtraMargin); } // convert back to the current item coordinate system var popupPos = mapFromItem(map, absPopupX, absPopupY); myPopup.x = popupPos.x; myPopup.y = popupPos.y; } onExited: { myCanvas.textVisible = false; } } } Popup { id: myPopup // original offset to allow mouse hover x: 20; y: 20; visible: false Label { text: model.name; horizontalAlignment: Text.AlignHCenter; } } } } } } }

@ChrisW67 Thank you so much for your recommendations! I will try.

@b-arun-kumar said in Order of QML property's dependency evaluation: Response from Qt Support: As per this old article: https://www.kdab.com/qml-engine-internals-part-2-bindings/, static value assignments happen during creation phase and binding value assignments happen at the end of creation phase. That is how it should be, literals first, then functions. But it is not actually documented so in theory it could change. This is also only true for simple literal assignments. Anything even slightly hinting about complexity makes QML engine postpone them together with all those needing the evaluation. For example it happens if you wrap the value with {} like this: p2: {true} Case 1: CustomQMLComponent{} In this case, based on the above article, p1 & p2 values are set by the time p3 value is set. The order in which these "static" properties are set is undefined and also the order in which more complex expressions are done are undefined. So it is best to avoid making assumptions about the order. Case 2: CustomQMLComponent{ p1: "my_string" p2: true } What happens in this case? In a more general sense, what happens when properties of a component are set when creating an instance of the component? Are the properties initialized with default values and then overridden by the new instance's values? Or, the properties are initialized just once with the default/new values. Just once. Although the properties do of course have some default value before the value in QML is assigned. The initial value set in constructor of a C++ class, or in case of QML defined property, default constructed value of the type (empty string, 0, false or null in case it is QObject* type). And why this could be important is because something like onXXXChanged signals are handled immediately when they occur and thus it could be ran before all those "static" assignment are done. Consider for example: onP1Changed: if (p2) {...} else {...} QML engine does not know that there is some dependency to p2 on p1 value change and in case p1 gets assigned before p2, this could take unexpected path and if p2 value change is not explicitly also handled properly in this case, could lead to mismatched state.

Hi, it seems ConicalGradient has been removed from Qt 6. There is probably a new alternative for that. Anyway you can still accessing it using the Qt5Compat module. See details here: https://doc.qt.io/qt-6/qml-qt5compat-graphicaleffects-conicalgradient.html Note you'll probably need to install the Qt5Compat module corresponding to your Qt version from the Maintenance Tools if that's not already the case.

You will get better performance (and more help from Qt docs) if you use QQuickPaintedItem and draw this in C++.

@GrecKo said in Is it safe to bind to C++ subobject's property in QML?: But why don't you do property var qmlCompProp: database.getDbpointObject() in yout qmlComp? prop1 and prop2 are passed to the database.getDbpointObject(prop1, prop2) function. prop1 and prop2 are properties of qmlComp. These properties are set when an instance of qmlComp is created. Item { required property string prop1 property bool prop2: false property var qmlCompProp: ({}) Component.onCompleted: { qmlCompProp = database.getDbpointObject(prop1, prop2) } } Since the properties evaluation order is undefined, and qmlCompProp depends on both prop1 and prop2 values, I've opted to initialize qmlCompProp with an empty object and assign the actual object in Component.onCompleted. Is this the right/recommended way, or is there a better way to handle this? Thanks for the information about the warning and it's workaround.

I'll check back tomorrow or Tuesday to see if I can better explain the code that I am about to share. I'm in a hurry today, so I'm just going to paste this and hope that anyone reading it can make use of it :) #include <QQmlComponent> #include <QQmlProperty> #include <QQuickItem> void dumpRecursive( int level, QObject* object ) { if( object ) { QByteArray buf; buf.fill( ' ', level / 2 * 8 ); if( level % 2 ) buf += " "; QString name = object->objectName(); QVariant propv = QQmlProperty::read( object, "visible" ); if( propv.isNull() ) { fprintf( stderr, "%s\n", "IS_NULL visible prop" ); } else { QQmlProperty prop( object, "visible" ); fprintf( stderr, "hasNotifySignal %d\n", static_cast<int>( prop.hasNotifySignal() ) ); fprintf( stderr, "isResettable %d\n", static_cast<int>( prop.isResettable() ) ); fprintf( stderr, "isSignalProperty %d\n", static_cast<int>( prop.isSignalProperty() ) ); fprintf( stderr, "isValid %d\n", static_cast<int>( prop.isValid() ) ); fprintf( stderr, "isWritable %d\n", static_cast<int>( prop.isWritable() ) ); fprintf( stderr, "propertyTypeName %s\n", prop.propertyTypeName() ); fprintf( stderr, "needsNotifySignal %d\n", static_cast<int>( prop.needsNotifySignal() ) ); // bool QQmlProperty::needsNotifySignal() const // QMetaMethod m = prop.method(); } QVariant prop = QQmlProperty::read( object, "testtest" ); if( !prop.isNull() ) { if( !prop.canConvert<QList<QVariant>>() ) { fprintf( stderr, "%s\n", "whoooooooooooooooooooooooooops ! ! !" ); } else { QList<QVariant> list = prop.toList(); fprintf( stderr, "wheeeeeeeeeeeeeeeee %p\n", reinterpret_cast<void*>( &list ) ); for( const auto& state : list ) { fprintf( stderr, "got one %p\n", reinterpret_cast<void*>( &list ) ); if( state.canConvert<QQuickItem*>() ) { QQuickItem* t = state.value<QQuickItem*>(); fprintf( stderr, "converts one %p\n", reinterpret_cast<void*>( t ) ); } } } } qDebug( "%s%s::%s", reinterpret_cast<const char*>( buf.data() ), object->metaObject()->className(), name.toLocal8Bit().data() ); QObjectList children = object->children(); if( !children.isEmpty() ) { for( int i = 0; i < children.size(); ++i ) dumpRecursive( level + 1, children.at( i ) ); } } } void localDump( QObject* object ) { dumpRecursive( 0, object ); } // return true if the event should be filtered (i.e. stopped) bool EventFilter::eventFilter( QObject* obj, QEvent* event ) { localDump( obj ); return QObject::eventFilter( obj, event ); }

@vinaygopal Sorry I know nothing about QML.

I resolved it. It because of RenderTarget. I rollback it to default value.

@jsulm thank you so much it worked with these code: function: void searchPaths(QVariant path) { QStringList files; // add files to this ( paths ) QStringList filter; // mp4 files filter filter << "*.mp4"; // add filter qInfo("-----"); QDirIterator dir(path.toString(), filter, QDir::Files, QDirIterator::Subdirectories); // get all files in directory while (dir.hasNext()) { qInfo() << dir.next(); files << dir.next(); // } } use: searchPaths("enter path here") now i can sleep easy. thanks

Hello, I want to know how to add a suffix to a file after saving it on filedialog in qml and I came here in hope to find my answer. But It makes me sad when I can't find it. I tried filePath = filePath + '.txt' but isn't working for me. Can anyone share a website with me in which I can find the solution? I will be very much thankful to you.

This is already fixed in 6.2.3, and 6.3

Guess you can give the string to RegExp constructor RegExpValidator {id:decimal_validator ; regExp: new RegExp(reg_expression)} Edit: Another point, I think you don't need to add extra "/" character if you define your regex using string. I think it should be either : property string reg_expression: "[0-9]+" or property RegExp reg_expression: /[0-9]+/ Note also you can use "\\d+" or /\d/ instead of "[0-9]+" for your regex You may also be interested by this great website for developing and testing regex: https://regex101.com Edit2: Correction of my stupid mistake of my first edit. regex for digit character is obviously \d and not \w

BUMP !!!!!!!

@vinaygopal "what if i want to access the visibility or a property i have defined in the delegate?" There are multiple instances of your delegate, corresponding to the part of the model being displayed. Which instance do you want the property from? If it's a common property that is not specific to a single instance, then the same answer applies - factor it out to the table level and use it in the delegate. If it is a property specific to a delegate instance you are interested in, how do you specify which delegate? Does the data actually belong to the model? What is it that you are trying to achieve?

I have figured this out, by using states and setting the parent. It's not particularly fluid but it works StateGroup { id: stateGroup states: [ State { name: "landscape" when: root.width >= 400 PropertyChanges { target: issueDetails parent: issueDetailsSplitViewContainer } PropertyChanges { target: issueDetailsSplitViewContainer visible: true } PropertyChanges { target: issueDetailsDrawer visible: false position: 0 } }, State { name: "portrait" when: root.width < 400 PropertyChanges { target: issueDetails parent: issueDetailsDrawerContainer } PropertyChanges { target: issueDetailsSplitViewContainer visible: false } } ] }

@vinaygopal according to the documentation: https://doc.qt.io/qt-5/qml-qtquick-controls-tableviewcolumn.html#delegate-prop this should do the trick: Component{ id:firstColumnComponent Item { id: toplevelItem property bool textpresent: true Row{ spacing: 10 TextField{ id:te width: 100 text: styleData.value maximumLength: 20 onAccepted:{ console.log("the editing is finished to",te.text) peopleTable.editfinished(te.text,styleData.value) } } Image { id: fav_image source: "qrc:/favourite_icon.png" height: 20 width: 40 MouseArea{ anchors.fill: parent onClicked: { console.log("the current index is",styleData.row) //Change happened here } } } } } }

Take a look at VXYModelMapper . It lets you create series from a QAbstractTableModel with not all the glue code you did here.

If you are making that many pages I would consider creating a model in C++ or QML to feed the data to a Repeater. This would give you more options for sharing data between pages.

@sierdzio It worked as you said. Thank you for your help. I wish that it was possible to put different icons into a resource file, to be able to call upon any of them at a time. I put the ico file into my project folder and called it from .pro (project) file with that single line of code. It wasn't necessary to call any sort of function of window decoration (perhaps I haven't observed the issue yet). However, I believe that it was necessary to convert that file into .ico, what is ... well... the whole point of SVG is scalability, so that they look the same on any sort of device. I don't understand why Microsoft would stick to that .ico "...ICO files contain one or more small images at multiple sizes and color depths, such that they may be scaled appropriately." Perhaps it makes sense in some way. I simply spent more time poking around HTML 5.
