QML and Qt Quick

@mahlersand Using private classes is not recommended as its implementation may change from version to version. The best would be to use QQuickPaintedItemand create your own custom types.

@Trikrista Do you mean something like exclude ?

Thanks. It worked

@mcosta Thanks for the reply. If I will not find any other ways I'll use different files.

Hi, Q_INVOKABLE is used to make functions accessible throughout Qt meta object system. Q_PROPERTY is much more complex and offers additional features

About my first question, I found the answer : contentItem.children.length contains 11 elements because there are 10 Rectangles (from the model) and the ListView itself. Knowing that, I cannot rely on the contentItem.children's indexes vs. currentIndex because it won't match. That's why I'm having problem at index=4 because contentItem.children[4] is the ListView. By using the itemAt() method instead of indexAt(), I succeeded to achieve what I wanted :-)

Hi, Thanks for sharing your solution. To mark as solved just edit the thread title and prepend [solved] to it :)

I've figured this out. The problem wasn't in fact due to image files pixel alpha. That works just fine. It had to do with the QQuickView not being transparent. What I am doing is displaying a QQuickView as a borderless window to be used as a popup dialog and I want to see through to the background, where there are no objects in the qml file. (Think of a pop up dialog with rounded corners). Here's what I'm doing: QQuickView view; // don't display an icon in the task bar // no border on the window view.setFlags(Qt::SubWindow | Qt::FramelessWindowHint); // make the view transparent so that the edges of the window, // where there is no image, show through to the background QSurfaceFormat surfaceFormat; surfaceFormat.setAlphaBufferSize(8); view.setFormat(surfaceFormat); view.setClearBeforeRendering(true); view.setColor(QColor(Qt::transparent)); // load qml file and display view.setSource(file.qml); view.show();

From the QT documentation it seem to be possible : Exposing Attributes of C++ Types to QML Any data that is transferred from C++ to QML, whether as a property value, a method parameter or return value, or a signal parameter value, must be of a type that is supported by the QML engine. So why it is not working ? Is any of you succeed returning one or more object through method parameters ?

Hi, Sorry for replying to this old topic but I have a similar problem : I would like to set the currentIndex (which is read only for a TreeView) in order to navigate throught items from the given currentIndex using the keyboard. Settings selection is OK, but it does NOT set the currentIndex, so pressing down arrow selects the first item of the TreeView, as currentIndex is still undefined at this step... Here some code to select : var index = controller.activeFolderIndex; treeViewSelectionModel.setCurrentIndex(index, ItemSelectionModel.ClearAndSelect); //then I would like something like : treeView.currentIndex = index; Any idea ?

Hi, QtQuickEnterpriseControls has pie menu. http://doc.qt.io/QtQuickEnterpriseControls/qml-qtquick-enterprise-controls-piemenu.html Can you share details ,how you implemented it? I am trying to implement a radial menu. Any help is appreciated.

Do you get any messages about slots/signals when connecting?(what I mean is "no such slot/signal")

You need to add the module path to QML import path. You can do that in 2 different ways: Add "<path-to-qml-material>/modules" to your QML2_IMPORT_PATH env var. Or add it in your main.cpp using engine.addImportPath("<path-to-qml-material>/modules/");
