C++ listmodel with section.property

lahianim

Hi all
ListView has section.property to devide the listmodel to sections
i need to create a c++ list model (of QString data) that support this section.property
how can i do that

Thanks

QStringList coupled with setContextProperty to use it in QML side (perhaps with some javascript for displaying the string you select).

Otherwise you can use a hidden ListView and use its model to display the one you need.

Thanks for your answer.

maybe i was not clear.
i have a cpp model using QAbstractListModel and i use it in QML files and it works ok
BUT
i want to have the section attribute that ListView have in QML and i dont know how to implement it in the QAbstractListModel
do i need to implement the headerData method in the QAbstractListModel??

Just to clarify in QML
section.property holds the name of the property that is the basis of each section.

If you look at the example in "QML Data Models":http://doc.qt.nokia.com/4.7-snapshot/qdeclarativemodels.html#qabstractitemmodel it shows that the roles in the c++ model is used in QML. In the example the roles are "type" and "size". So if you want to create a section base on "type" you would alter the QML example (in the link) to:
@ListView {
width: 200; height: 250
anchors.fill: parent

 model: myModel
 delegate: Text { text: "Animal: " + type + ", " + size }
 section.property: type

}@

Hope that is what you are looking for. The above snippet is untested of course

I have the same problem and i found solution - you should write
section.property: "modelData.<propertyName>"
