问题 I can import JavaScript files which are already part of the project tree like this: import "myFile.js" as MyFile Is there any way to do this for external files that aren't already included in my project, i.e. by passing an absolute or relative path to the file on my disc? 回答1: For some questions that go like: Is it possible to do something like [this...] usually the easiest way, is to try it out. In your question a important detail is missing: Is the QML file in question in a qrc -file or not

问题 Suppose I have a map, and a few polygons. I want to render them and take a screenshot of each one of them. If the QQuickView is visible, thats easy. But, how could I achieve this, with the QQuickView not visible , like a background task ? Any ideas?

问题 Implemented QML Dynamic View Ordering by Dragging View Items using this Qt tutorial: QML Dynamic View Ordering Tutorial. Original underlying model is QAbstractListModel descendant in our case. Model stores data in a QList<QObject*> objectList; field type. Works fine, however item ordering changed in proxy DelegateModel only. How to change items order automatically in original underlying model as well for other C++ and QML consumers where order matters? Or I could we otherway access some

问题 I'm running the official Qt 5.5 SDK on Ubuntu 15.10 and trying to play 3D sounds in QML: import QtAudioEngine 1.0 The project file: qt += multimedia The import statement results in qrc:///Main.qml:1:1: module "QtAudioEngine" is not installed .

问题 I can't isolate what is causing the application to crash on exit. What adds further confusion is that it doesn't always crash, sometimes it does, sometimes it doesn't and it seems to be completely arbitrary. The sample basically crates a custom image provider that loads a static google maps API request as a PNG image to show in QML. The image provider itself works, I first suspected that the issue might be with instantiating the network access manager on the stack, but that's not it, I get
