<h2>Detailed Description</h2>
<p>FileDialog provides a basic file chooser: it allows the user to select existing files and/or directories, or create new filenames. The dialog is initially invisible. You need to set the properties as desired first, then set <a href="qml-qtquick-dialogs-filedialog.html#visible-prop">visible</a> to true or call <a href="qml-qtquick-dialogs-filedialog.html#open-method">open()</a>.</p>
<p>Here is a minimal example to open a file dialog and exit after the user chooses a file:</p>
<pre class="qml">import QtQuick 2.2
import QtQuick.Dialogs 1.0

<span class="type">FileDialog</span> {
    <span class="name">id</span>: <span class="name">fileDialog</span>
    <span class="name">title</span>: <span class="string">&quot;Please choose a file&quot;</span>
    <span class="name">onAccepted</span>: {
        <span class="name">console</span>.<span class="name">log</span>(<span class="string">&quot;You chose: &quot;</span> <span class="operator">+</span> <span class="name">fileDialog</span>.<span class="name">fileUrls</span>)
        <span class="name">Qt</span>.<span class="name">quit</span>()
    }
    <span class="name">onRejected</span>: {
        <span class="name">console</span>.<span class="name">log</span>(<span class="string">&quot;Canceled&quot;</span>)
        <span class="name">Qt</span>.<span class="name">quit</span>()
    }
    <span class="name">Component</span>.onCompleted: <span class="name">visible</span> <span class="operator">=</span> <span class="number">true</span>
}</pre>
<p>A FileDialog window is automatically transient for its parent window. So whether you declare the dialog inside an <a href="../qtquick/qml-qtquick-item.html">Item</a> or inside a <a href="../qtquick/qml-qtquick-window-window.html">Window</a>, the dialog will appear centered over the window containing the item, or over the Window that you declared.</p>
<p>The implementation of FileDialog will be a platform file dialog if possible. If that isn't possible, then it will try to instantiate a <a href="../qtwidgets/qfiledialog.html">QFileDialog</a>. If that also isn't possible, then it will fall back to a QML implementation, DefaultFileDialog.qml. In that case you can customize the appearance by editing this file. DefaultFileDialog.qml contains a Rectangle to hold the dialog's contents, because certain embedded systems do not support multiple top-level windows. When the dialog becomes visible, it will automatically be wrapped in a Window if possible, or simply reparented on top of the main window if there can only be one window.</p>

<p>Modality does not mean that there are any blocking calls to wait for the dialog to be accepted or rejected; it's only that the user will be prevented from interacting with the parent window and/or the application windows at the same time.
