<p>
<a class="link" href="GtkFileChooser.html" title="GtkFileChooser"><span class="type">GtkFileChooser</span></a>, starting with GTK+ 2.4, is the new set of APIs for file
selection widgets and dialogs. Previous versions of GTK+ used <a class="link" href="GtkFileSelection.html" title="GtkFileSelection"><span class="type">GtkFileSelection</span></a>,
which has numerous problems.
</p>
<p>
<a class="link" href="GtkFileChooser.html" title="GtkFileChooser"><span class="type">GtkFileChooser</span></a> is an abstract interface that can be implemented by widgets
that perform file selection tasks. Two widgets in GTK+ implement this
interface: <a class="link" href="GtkFileChooserDialog.html" title="GtkFileChooserDialog"><span class="type">GtkFileChooserDialog</span></a> and <a class="link" href="GtkFileChooserWidget.html" title="GtkFileChooserWidget"><span class="type">GtkFileChooserWidget</span></a>. Most applications
simply need to use <a class="link" href="GtkFileChooserDialog.html" title="GtkFileChooserDialog"><span class="type">GtkFileChooserDialog</span></a>, which is a dialog box that allows the
user to select existing files for opening them, or to pick new filenames for
saving documents. <a class="link" href="GtkFileChooserWidget.html" title="GtkFileChooserWidget"><span class="type">GtkFileChooserWidget</span></a> is for special applications that need to
embed a file selection widget inside a larger window. In the context of GTK+,
<a class="link" href="GtkFileChooserDialog.html" title="GtkFileChooserDialog"><span class="type">GtkFileChooserDialog</span></a> is simply a <a class="link" href="GtkDialog.html" title="GtkDialog"><span class="type">GtkDialog</span></a> box with a <a class="link" href="GtkFileChooserWidget.html" title="GtkFileChooserWidget"><span class="type">GtkFileChooserWidget</span></a>.
inside.

<p>
To create a <a class="link" href="GtkFileChooserDialog.html" title="GtkFileChooserDialog"><span class="type">GtkFileChooserDialog</span></a>, you simply call <a class="link" href="GtkFileChooserDialog.html#gtk-file-chooser-dialog-new" title="gtk_file_chooser_dialog_new ()"><code class="function">gtk_file_chooser_dialog_new()</code></a>.
This function is similar to <a class="link" href="GtkDialog.html#gtk-dialog-new" title="gtk_dialog_new ()"><code class="function">gtk_dialog_new()</code></a> in that it takes parameters for the
title of the dialog box and its transient parent, as well as its
buttons. In addition, it takes in an argument that determines
whether the file chooser dialog will be used for opening
existing files or for saving to a possibly new file.
</p>
<p>
Please see <a class="xref" href="">???</a> for
how to create a simple file chooser dialog and extract the
selected filename from it.
