How to reload GridView

[fas.ysk]

Hello,
What's the right way to reload data in GridView ?

for example:

@function getSomeData(indx)
{
var str = pCore.getSomeData(indx);
return str;
}

GridView {
id: gridView
model: 20
delegate: Item {
Text {
text: getSomeData(index);
}
}
}@

pCore.getSomeData is method in C++ code like that: Q_INVOKABLE QString getSomeData(int nIndex);

It works perfect but sometimes I need refresh data in items.
How I can do it ?

Does the first text using getSomeData(index) is OK ?

Delegate shud be just a dummy item for displaying..
You should get the data via a listModel. And on need of refresh, set listModel = 0 and again set listModel to desired array/model.

Hi,

Why don't you present your data as QStringList? QStringList can be used as model - http://doc.qt.nokia.com/4.7-snapshot/qdeclarativemodels.html#qstringlist-based-model

You can do something like this: In your C++ object define a property of type QStringList ( I think this is possible ). When you change some data in C++, emit signal that data has changed. This will automaticaly reload your model.

I also think this is the preferred way
