\class QQmlFileSelector
\since 5.2
\inmodule QtQml
\brief A convenience class for applying a QFileSelector to QML file loading
QQmlFileSelector is a QQmlAbstractUrlInterceptor which will automatically apply a QFileSelector to
qml file and asset paths.
It is used as follows:
\code
QQmlEngine engine;
QQmlFileSelector selector;
engine.setUrlInterceptor(&selector);
\endcode
Then you can swap out files like so:
\code
main.qml
Component.qml
asset.png
+unix/Component.qml
+mac/asset.png
\endcode
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 \c QFileSelector.
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.
*/
/*!
Creates a new QQmlFileSelector, which includes its own QFileSelector.
*/
QQmlFileSelector::QQmlFileSelector(QObject* parent)
: QObject(*(new QQmlFileSelectorPrivate), parent)
{
}

{
Q_Q(QQmlFileSelector);
ownSelector = true;
selector = new QFileSelector(q);
}
