Returns the item at index in the list model.

This allows the item data to be accessed (but not modified) from JavaScript. It returns an Object with a property for each role.

• int i the row we want

Property Documentation

int Plasma::DataModel::count

read

How many items are in this model.

Definition at line 151 of file datamodel.h.

QObject * Plasma::DataModel::dataSource

readwrite

The instance of DataSource to construct this model on.

Definition at line 135 of file datamodel.h.

QString Plasma::DataModel::keyRoleFilter

readwrite

It's a regular expression.

Only data with keys that match this filter expression will be inserted in the model

Definition at line 140 of file datamodel.h.

QString Plasma::DataModel::sourceFilter

readwrite

it's a regular expression.

If the DataSource is connected to more than one source, only inserts data from sources matching this filter expression in the model. If we want to have a source watch all sources beginning with say "name:", the required regexp would be sourceFilter: "name:.*"
