@short A model to combine several QStandardItemModel's into one.
|
|
Combine standard models into the aggregate model to display them in the one view.
|
|
|
|
Each new model gets its own parent item to differentiate items between different models,
|
|
for example:
|
|
|
|
Tea Model:
|
|
@code
|
|
- Black
|
|
- Green
|
|
- White
|
|
@endcode
|
|
Coffee Model:
|
|
@code
|
|
- Arabica
|
|
- Robusta
|
|
@endcode
|
|
|
|
When aggregated with
|
|
@code
|
|
AggregateModel model;
|
|
model->addModel("Tea", teaModel);
|
|
model->addModel("Coffee", coffeeModel);
|
|
@endcode
|
|
they will look as:
|
|
@code
|
|
- Tea
|
|
- Black
|
|
- Green
|
|
- White
|
|
- Coffee
|
|
- Arabica
|
|
- Robusta
|
|
@endcode
|
|
|
|
@note It is impossible to aggregate any model, aggregation works only for standard models.
|
|
@note Currently aggregate model displays only 1 column.
