Detailed Description

template<class TYPE>
class ViewSolutions::BaseListModel< TYPE >

The BaseListModel class is the base class of all GUI list models.

A BaseListModel stores its items in a simple list and exposes them to QML as a list model. The list of all items is also available in QML through the listDate property (see the BASE_LIST_MODEL_DATA_PROPERTY macro).

Template Parameters

TYPE	- is main stored delegate model of all list items.

Concepts and usage rules:

• All models should provide delegate models based on QObject
• If the model requires a fast solution, just implement a BaseListModel<int> model

Note

To access the delegate model use the Qt::EditRole role: it is available in QML by the delegateModel keyword.

Example of a model based on the BaseListModel:

class VariantListModel: public ViewSolutions::BaseListModel<QVariant>
{
    Q_OBJECT
    BASE_LIST_MODEL_DATA_PROPERTY(QVariant)
 
public:
    VariantListModel(QObject* ptr = nullptr):
        ViewSolutions::BaseListModel<QVariant>(ptr) {}
};

C++ usage:

VariantListModel model;
 
QList<QVariant> items;
items << "one" << "two" << "three";
model.setDataList(items);
 
const QList<QVariant>& values = model.dateList();

QML usage (after the model was registered as context property):

ListView {
    model: variantListModel
    delegate: Text { text: delegateModel }
}
