Hi,
I have a group of QActions defined in c++ that I want to be able to
arrange and access in qml.
I thought of writing two components like this and am wondering if it
is possible:
KPIM.ActionTreeFactory {
id :myTree
actionTree : [
"edit",
[
"cut",
"copy",
"move"
]
"view"
[
"month",
"week",
"day"
]
"message"
[
"sign",
[
"Use GPG",
"Use SMime"
]
"encrypt"
[
"Use GPG",
"Use SMime"
]
]
]
}
KPIM.ActionMenuContainer {
x : 100
y : 100
width : 200
height : 200
numActions : 2
model : myTree.model
}
As you can see, the ActionTreeFactory defines a list of lists. I am
hoping I can implement it something like this:
class ActionTreeFactory {
Q_PROPERTY(QObject model READ model NOTIFY modelChanged )
Q_PROPERTY(QVariant actionTree READ actionTree WRITE setActionTree )
public:
void populateModel(const QVariant &actionTree, const QModelIndex &parent)
{
QVariantList contents = actionTree.toList();
foreach (const QVariant &content, contents)
{
if (content.type() == QVariant::String)
{
QString actionName = content.toString();
qDebug() << "GOT ACTION" << actionName;
m_model->appendAction(parent, actionName);
}
if (content.type() == QVariant::List)
{
qDebug() << "GOT LIST";
Q_ASSERT(m_model->hasChildren(parent));
populateModel(content,
m_model->index(m_model->rowCount(parent) - 1, 0, parent));
}
}
}
void setActionTree(const QVariant &actionTree)
{
m_model = new ActionTreeModel(this);
populateModel(actionTree, QModelIndex());
}
QObject* model() const {
return qobject_cast<QObject*>(m_model);
}
private:
QAbstractItemModel *m_model;
};
That is, I'm hoping I can get the action tree somehow as a list of
lists. In my example I assumed I could get it as a QVariant, but if
it's QScriptValue instead I think that would work too. So is some
implementation like that possible?
Turning the tree of action names into a accessible tree of actions is
a separate problem, but I think it's possible. If the above is not
possible though I'll need to come up with another solution. I can't
find much docs on how to implement Components in c++. Does anyone have
a better idea for a scalable solution to defining groups of actions in
QML?

I think maybe this would be useful?

All the best,
