QML and Qt Quick

yes, this causes the error.

I do not know, it's something you can ask on the interest mailing list. As for the Declarative Widgets project, I don't think they do anything special for look and feel. The goal is to be able to use widgets in QtQuick applications. I don't know the current plans for widgets on mobile.

thank you for your response I started a project on Qt Design Studio and then convert it into a Quick project Now the only files I have are ui.qml files Now I need to call the signals from the c ++ files this is my question: how can i call c++ function when i clicked on a shape in ui.qml file?

Well, after a some close investigation I have solved my issue. I could not call model's methods because of using the following syntax in delegate's items: model.close() So as far I understood in this case we don't have access directly to model's methods. But if I define my model as a context property: engine.rootContext()->setContextProperty("wordsStorage", backend.wordsStorage()); everything works well and pretty enough. Finally QSqlQueryModel has nothing to do with it. Such thing happens with an arbitrary model. I'm going to mark this topic as 'solved', but anyway: is there a way to do this without using root context? Otherwise QML part is going to be full of this contexts in a large project. Is it okay or not?

@mnhg hi for(var i in ary) grp1.append(ary[i],i)

Thank you very much! I find that glviewport() function control this. It draws everything by four elements. I draw what I want at right position, and it worked!

@raven-worx Thank you so much . I finally make it .

@LorenDB do you mean https://doc.qt.io/qt-5/qml-qtquick-layouts-layout.html#fillHeight-attached-prop https://doc.qt.io/qt-5/qml-qtquick-layouts-layout.html#fillWidth-attached-prop

@SumitK hi see https://doc.qt.io/qt-5/qtquickcontrols2-customize.html#customizing-progressbar

You don't. Write your own camera controller and handle the transformation yourself.

@Philomath-Qt said in Print current timestamp in Milliseconds since epoch time in QML: Unfortunately my QML file prints the time two times, because for some reason the signal of the qobject is received twice instead of once. I'm not the first one that has this problem, but to find the root of this problem is rather complecated (origin seems to be multithreading). If you know a easy workaround, so that the the console.log only gets printed every second time, please let me know. I would rather try to fix the real issue, but if you really want to do that then go ahead.. @Philomath-Qt said in Print current timestamp in Milliseconds since epoch time in QML: edit: getTime() doesn't work for some reason, i had to use Date.now() the reason should be printed in the "application output" tab of you editor this works var date = new Date() console.log(date.getTime())

The patch is public so you can build the module yourself to have the fix.

@J-Hilk I got it to work with ifw as well. However, the option --plugindir apparently does not work correctly. The plugins were stored in the folder of the exe. However, also the installation using ifw was finally successful.

So the problem was obvious because of following lines: #ifdef Q_OS_LINUX qputenv("QT_IM_MODULE", QByteArray("qtvirtualkeyboard")); #endif Changed to #if defined(Q_OS_LINUX) && !defined(Q_OS_ANDROID) qputenv("QT_IM_MODULE", QByteArray("qtvirtualkeyboard")); #endif And voila: Android keyboard works! :)

You are trying to do 2 things that require the same actions. Drag and drop is not built into the TextInput object. So you need to learn how drag and drop works. Next, since you need to be able to change the mode of your TextInput you need to control when a selection can occur. Say for instance if text is selected that you do NOT want selection motion to work. Then use the selectedText property to control the selectByMouse property: selectByMouse: selectedText <= 0 I do not know if this will lock you into that mode. So you may need a way to back out of a selection. What happens when you click the text again? Does it deselect the text?
