QQmlFileSelector will automatically apply a QFileSelector to qml file and asset paths.
It is used as follows:
Then you can swap out files like so:
main.qml Component.qml asset.png +unix/Component.qml +mac/asset.png
In this example, main.qml will normally use Component.qml for the Component type. However on a unix platform, the unix selector will be present and the +unix/Component.qml version will be used instead. Note that this acts like swapping out Component.qml with +unix/Component.qml, so when using Component.qml you should not need to alter any paths based on which version was selected.
For example, to pass the "asset.png" file path around you would refer to it just as "asset.png" in all of main.qml, Component.qml, and +linux/Component.qml. It will be replaced with +mac/asset.png on Mac platforms in all cases.
For a list of available selectors, see
Your platform may also provide additional selectors for you to use. As specified by QFileSelector, directories used for selection must start with a '+' character, so you will not accidentally trigger this feature unless you have directories with such names inside your project.
If a new QQmlFileSelector is set on the engine, the old one will be replaced. Use QQmlFileSelector::get() to query or use the existing instance.
Member Function Documentation
QQmlFileSelector::QQmlFileSelector(QQmlEngine *engine, QObject *parent = nullptr)
Creates a new QQmlFileSelector with parent object parent, which includes its own QFileSelector. engine is the QQmlEngine you wish to apply file selectors to. It will also take ownership of the QQmlFileSelector.
Destroys the QQmlFileSelector object.
[static] QQmlFileSelector *QQmlFileSelector::get(QQmlEngine *engine)
This function is deprecated.
Gets the QQmlFileSelector currently active on the target engine.
This method is deprecated. You should not retrieve the files selector from an engine after setting it. It may be in use.
If the engine passed here is a QQmlApplicationEngine that hasn't loaded any QML files, yet, it will be initialized. Any later calls to QQmlApplicationEngine::setExtraFileSelectors() will have no effect.
See also QQmlApplicationEngine.
[since 5.7] QFileSelector *QQmlFileSelector::selector() const
This function was introduced in Qt 5.7.
See also setSelector().
void QQmlFileSelector::setExtraSelectors(const QStringList &strings)
void QQmlFileSelector::setSelector(QFileSelector *selector)
Sets the QFileSelector instance for use by the QQmlFileSelector to selector. QQmlFileSelector does not take ownership of the new QFileSelector. To reset QQmlFileSelector to use its internal QFileSelector instance, call setSelector(0).
