PySide implementation of QML exposed QSortFilterProxyModel

PyQmlSortFilterProxyModel

This project is a python PySide6 port of https://github.com/oKcerG/SortFilterProxyModel; a QSortFilterProxyModel exposed to QML written by oKcerG.

Please refer to oKcerG's documentation for usage as much of this implementation is based on oKcerG's implementation.

Note: the version of the qml exposed SortFilterProxyModel is 0.2 to match that of oKcerG's project so that existing .qml code from your projects can be re-used quickly.

Components not (yet) ported

• ProxyRoles
• QQmlSortFilterProxyModel::componentCompleted. In PySide6, there is no Q_INTERFACES macro enabling a class to inherits from QSortFilterProxyModel and QQmlParserStatus. Hence inheriting from QQmlParserStatus doesn't cause errors, however the componentCompleted method is not called.
• Some of the sorters are not yet ported
• The delay functionality is not ported
• Attached properties not ported

Differences - Container Filters

Because attached properties are not ported, there is a difference in using the AnyOf and AllOf filters:

// oKcerG's
AnyOf {
    RoleFilter {...}
    RegExpFilter {...}
    //...
}

// python implementation
AnyOf {
    // need to assign a list of Filter to the filters property
    filters: [
        RoleFilter {...},
        RegExpFilter {...},
        //...
    ]
}

Usage

1. download /clone the repostitory
2. copy src/qmlsortfilterproxymodel to your project
3. import and register the SortFilterProxyModel to qml

# main.py
import qmlsortfilterproxymodel
# register qml types before QQmlApplicationEngine.load("main.qml") is called
qmlsortfilterproxymodel.registerQmlTypes()

4. Instantiate SortFilterProxyModel in qml

// SomeFile.qml
import SortFilterProxyModel 0.2


SortFilterProxyModel {
    //...
}

Running the Example

1. Create a virtual environment (currently venv folder is under .gitignore) and activate python3 -m venv venv source venv/bin/activate
2. Install requirements (PySide6) pip3 install -r requirements.txt
3. Run the example project python3 example/main.py

Once the example window launches, you can use the TextField to filter by name.
