* \brief This class provides model containing CaEntry class objects.
|
|
|
35 |
*
|
|
|
36 |
* To create instance of CaItemModel object, you need to pass CaQuery
|
|
|
37 |
* object in constructor. CaQuery should describe items that you want
|
|
|
38 |
* to have in a model.
|
|
|
39 |
*
|
|
|
40 |
* \example
|
|
|
41 |
* \code
|
|
|
42 |
*
|
|
|
43 |
* CaQuery query;
|
|
|
44 |
* query.setFlagsOn(VisibleEntryFlag);
|
|
|
45 |
* query.setParentId(collectionId);
|
|
|
46 |
* CaItemModel* model = new CaItemModel(query, this);
