ItemMonitor Class Reference
from PyKDE4.akonadi import *
Namespace: Akonadi
Detailed Description
A convenience class to monitor a single item for changes.
This class can be used as a base class for classes that want to show a single item to the user and keep track of status changes of the item without having to using a Monitor object themself.
Example:
// A label that shows the name of a contact item
class ContactLabel : public QLabel, public Akonadi.ItemMonitor
{
public:
ContactLabel( QWidget *parent = 0 )
: QLabel( parent )
{
setText( "No Name" );
}
protected:
virtual void itemChanged( const Akonadi.Item &item )
{
if ( item.mimeType() != "text/directory" )
return;
const KABC.Addressee addr = item.payload<KABC.Addressee>();
setText( addr.fullName() );
}
virtual void itemRemoved()
{
setText( "No Name" );
}
};
...
ContactLabel *label = new ContactLabel( this );
const Akonadi.Item item = fetchJob->items().first();
label->setItem( item );

Method Documentation
| __init__ | ( | self ) |
Creates a new item monitor.
| Akonadi.ItemFetchScope fetchScope | ( | self ) |

Since this returns a reference it can be used to conveniently modify the current scope in-place, i.e. by calling a method on the returned reference without storing it in a local variable. See the ItemFetchScope documentation for an example.
- Returns:
- a reference to the current item fetch scope
- See also:
- setFetchScope() for replacing the current item fetch scope
| Akonadi.Item item | ( | self ) |
Returns the currently monitored item.
| itemChanged | ( | self, | ||
| Akonadi.Item | item | |||
| ) |
This method is called whenever the monitored item has changed.
- Parameters:
-
item The changed item.
| itemRemoved | ( | self ) |
This method is called whenever the monitored item has been removed.
| setFetchScope | ( | self, | ||
| Akonadi.ItemFetchScope | fetchScope | |||
| ) |
Sets the item fetch scope.
Controls how much of an item's data is fetched from the server, e.g. whether to fetch the full item payload or only meta data.
- Parameters:
-
fetchScope The new scope for item fetch operations.

- fetchScope()
| setItem | ( | self, | ||
