PredicateProperties Class Reference
from PyKDE4.kio import *
Detailed Description
A predicate is part of the RDF trinity: subject, predicate, object. It is identified by URI and it defines the type of the relationship. For file metadata, a predicate can be seen as a fieldname. It has a data type, a description, a short id, a cardinality

Enumeration Documentation
| Attributes |
This enum is used to specify some attributes that an item can have, which fit neither in the Hint nor in the Unit enum.
- Enumerator:
-
Addable = 1 The item or group can be added by a user < p>
Removable = 2 It can be removed < p>
Modifiable = 4 The value can be edited (no meaning for a group) < p>
Cumulative = 8 If an application wants to display information for more than one file, it may add up the values for this item (e.g. play time of an mp3 file) < p>
Averaged = 16 Similar to Cumulative, but the average should be calculated instead of the sum < p>
MultiLine = 32 This attribute says that a string item is likely to be more than one line long, so for editing, a widget capable for multline text should be used < p>
SqueezeText = 64 If the text for this item is very long, it should be squeezed to the size of the widget where it's displayed < p>
