\brief Dialog component for choosing files from a local filesystem.

\internal
QtFileDialog provides a means to instantiate and manage a QFileDialog.
It is not recommended to be used directly; it is an implementation
detail of \l FileDialog in the \l QtQuick.Dialogs module.
To use this type, you will need to import the module with the following line:
\code
import QtQuick.PrivateWidgets 1.0
\endcode
*/
/*!
\qmlsignal QtQuick::Dialogs::FileDialog::accepted
The \a accepted signal is emitted when the user has finished using the
dialog. You can then inspect the \a fileUrl or \a fileUrls properties to
get the selection.
Example:
\qml
FileDialog {
onAccepted: { console.log("Selected file: " + fileUrl) }
}
\endqml
The corresponding handler is \c onAccepted.
*/
/*!
\qmlsignal QtQuick::Dialogs::FileDialog::rejected
The \a rejected signal is emitted when the user has dismissed the dialog,
either by closing the dialog window or by pressing the Cancel button.
The corresponding handler is \c onRejected.
