Hi there,
I've a bunch of classes which define a number of Q_PROPERTies with
type QList<some-QObject-based-class *>. Those classes are inspected by
a generic widgets-based property editor which uses QMetaProperty
functions to handle item's properties.
E.g:
class Q_UML_EXPORT QUmlClass : public QWrappedObject
{
Q_OBJECT
Q_CLASSINFO("MetaModelPrefix", "QUml")
...
Q_PROPERTY(QList<QUmlOperation *> ownedOperations READ ownedOperations)
Q_PROPERTY(QList<QUmlProperty *> ownedAttributes READ ownedAttributes)
...
Now, I need to use QML to provide some visual representation of those
same elements and, therefore, QML objects should be dynamically
created based on QList-based properties' contents:
import QtQuick 2.0
Rectangle {
...
UmlSlot {
id: nameSlot
}
UmlSlot {
id: propertiesSlot
anchors.top: nameSlot.bottom
anchors.topMargin: -1
height: nameSlot.height; width: nameSlot.width
}
...
Component.onCompleted: {
if (element) {
var visibility;
switch (element.visibility) {
case 0: visibility = "+"; break;
case 1: visibility = "-"; break;
case 2: visibility = "#"; break;
case 3: visibility = "~"; break;
}
name = visibility + element.objectName;
nameSlot.labelFont.italic = element.isAbstract; // Works
fine so far ...
element.ownedAttributes <- here I got an undefined object
}
}
}
Qt5 docs say that such properties should be declared as
QQmlListProperty, but I'm wondering if I have to maintain two
different classes/properties in order to have this working. I haven't
used qmlRegisterType() so far, it seems QObject-based type are
automatically registered in QML as metatype registration do in Qt5.
So, any hints on how to have such QML/C++ things living together ?
Thanks in advance,
