QML ListView: model like Array of Arrays. How?

[bogong]

Hello all!
Is there any way to pass array of arrays to QML ListView and how to access data from this array-of-arrays?
Something like this:

property var pData: [
	["Field_0-01","Field_0-02","Field_0-03","Field_0-04","Field_0-05"],
	["Field_1-01","Field_1-02","Field_1-03","Field_1-04","Field_1-05"],
	["Field_2-01","Field_2-02","Field_2-03","Field_1-04","Field_2-05"],
	["Field_3-01","Field_3-02","Field_3-03","Field_1-04","Field_3-05"],
	["Field_4-01","Field_4-02","Field_4-03","Field_1-04","Field_4-05"],
	["Field_5-01","Field_5-02","Field_5-03","Field_1-04","Field_5-05"],
	["Field_6-01","Field_6-02","Field_6-03","Field_1-04","Field_6-05"],
	["Field_7-01","Field_7-02","Field_7-03","Field_1-04","Field_7-05"]
];

...

ListView {

	...
	model: pData;
	...
}

For me works only direct access to pData by currentIndex of ListView:

oApplicationWindow.pData[index][0]

But is there way to access it through "model"?

This might work:

modelData[0]

@sierdzio Thx. It works.

@sierdzio Do you know which method should be implemented for the same functionality if I am developing my own/custom data model based on QAbstractListModel?

[sierdzio]

Declare roles by reimplementing roleNames(), then, in data() use these roles to return your data. In QML, use the names specified by roleNames() to access the data.

So, for a very short example (pseudocode, sorry I don't have time to check all params etc.):

QHash<> roleNames() {
  return { Qt::UserRole + 1, "myRole" };
}

QVariant data() {
  if (role == Qt::UserRole+1) {
    return QVariantList{ "A", "B", "C" };
  }
}

/// QML:
console.log(myRole[0] // Will print "A")

@sierdzio Thx. I've got roleNames missed. It's mean "modelData" just a role name. I though it's Qt-system value. Briefly all of it looks like model within only one role where stored QVariantList that is transforming into JS-Array in QML.
