52 \class QQmlFileSelector-
53 \since 5.2-
54 \inmodule QtQml-
55 \brief A class for applying a QFileSelector to QML file loading.-
56-
57 QQmlFileSelector will automatically apply a QFileSelector to-
58 qml file and asset paths.-
59-
60 It is used as follows:-
61-
62 \code-
63 QQmlEngine engine;-
64 QQmlFileSelector* selector = new QQmlFileSelector(&engine);-
65 \endcode-
66-
67 Then you can swap out files like so:-
68 \code-
69 main.qml-
70 Component.qml-
71 asset.png-
72 +unix/Component.qml-
73 +mac/asset.png-
74 \endcode-
75-
76 In this example, main.qml will normally use Component.qml for the Component type. However on a-
77 unix platform, the unix selector will be present and the +unix/Component.qml version will be-
78 used instead. Note that this acts like swapping out Component.qml with +unix/Component.qml, so-
79 when using Component.qml you should not need to alter any paths based on which version was-
80 selected.-
81-
82 For example, to pass the "asset.png" file path around you would refer to it just as "asset.png" in-
83 all of main.qml, Component.qml, and +linux/Component.qml. It will be replaced with +mac/asset.png-
84 on Mac platforms in all cases.-
85-
86 For a list of available selectors, see \c QFileSelector.-
87-
88 Your platform may also provide additional selectors for you to use. As specified by QFileSelector,-
89 directories used for selection must start with a '+' character, so you will not accidentally-
90 trigger this feature unless you have directories with such names inside your project.-
91-
92 If a new QQmlFileSelector is set on the engine, the old one will be replaced. Use-
93 \l QQmlFileSelector::get() to query or use the existing instance.-

98 its own QFileSelector. \a engine is the QQmlEngine you wish to apply file-
