href="GtkFileChooser.html" title="GtkFileChooser"><span class="type">GtkFileChooser</span></a>. Files can be filtered based on their name(with <a class="link" href="gtk-gtkfilefilter.html#gtk-file-filter-add-pattern"><code class="function">gtk_file_filter_add_pattern()</code></a>), on their mime type (with<a class="link" href="gtk-gtkfilefilter.html#gtk-file-filter-add-mime-type"><code class="function">gtk_file_filter_add_mime_type()</code></a>), or by a custom filter function(with <a class="link" href="gtk-gtkfilefilter.html#gtk-file-filter-add-custom"><code class="function">gtk_file_filter_add_custom()</code></a>). </p><p>Filtering by mime types handles aliasing and subclassing of mimetypes; e.g. a filter for text/plain also matches a file with mime type application/rtf, since application/rtf is a subclass of text/plain. Note that <a class="link" href="gtk-gtkfilefilter.html#GtkFileFilter"><span class="type">GtkFileFilter</span></a> allows wildcards for the subtype of a mime type, so you can e.g. filter for image/*.</p><p>Normally, filters are used by adding them to a <a class="link" href="GtkFileChooser.html" title="GtkFileChooser"><span class="type">GtkFileChooser</span></a>,see <a class="link" href="GtkFileChooser.html#gtk-file-chooser-add-filter"><code class="function">gtk_file_chooser_add_filter()</code></a>, but it is also possibleto manually use a filter on a file with <a class="link" href="gtk-gtkfilefilter.html#gtk-file-filter-filter"><code class="function">gtk_file_filter_filter()</code></a>.</p></div><div class="refsect1" lang="en"><a name="id4041478"></a><h2>Details</h2><div class="refsect2" lang="en"><a name="id4041488"></a><h3><a name="GtkFileFilter-struct"></a>GtkFileFilter</h3><a class="indexterm" name="id4041502"></a><pre class="programlisting">typedef struct _GtkFileFilter GtkFileFilter;</pre><p>The <span class="structname">GtkFileFilter</span> struct containsonly private fields and should not be directly accessed.</p></div><hr><div class="refsect2" lang="en"><a name="id4041522"></a><h3><a name="GtkFileFilterInfo"></a>GtkFileFilterInfo</h3><a class="indexterm" name="id4041534"></a><pre class="programlisting">typedef struct { GtkFileFilterFlags contains; const gchar *filename; const gchar *uri; const gchar *display_name; const gchar *mime_type;} GtkFileFilterInfo;</pre><p>A <span class="structname">GtkFileFilterInfo</span> struct is usedto pass information about the tested file to <a class="link" href="gtk-gtkfilefilter.html#gtk-file-filter-filter"><code class="function">gtk_file_filter_filter()</code></a>. </p><div class="variablelist"><table border="0"><col align="left" valign="top"><tbody><tr><td><p><span class="term"><a class="link" href="gtk-gtkfilefilter.html#GtkFileFilterFlags">GtkFileFilterFlags</a> <em class="structfield"><code>contains</code></em>;</span></p></td><td>Flags indicating which of the following fields need are filled</td></tr><tr><td><p><span class="term">const <ahref="/usr/share/gtk-doc/html/glib/glib-Basic-Types.html#gchar">gchar</a> *<em class="structfield"><code>filename</code></em>;</span></p></td><td>the filename of the file being tested</td></tr><tr><td><p><span class="term">const <ahref="/usr/share/gtk-doc/html/glib/glib-Basic-Types.html#gchar">gchar</a> *<em class="structfield"><code>uri</code></em>;</span></p></td><td>the URI for the file being tested</td></tr>⌨️ 快捷键说明
