122<hr><a name="details"></a><h2>Detailed Description</h2>
123
124
125The QFileDialog class provides dialogs that allow users to select files or directories.
126
127
128<p> The QFileDialog class enables a user to traverse their file system in
129order to select one or many files or a directory.
130<p> The easiest way to create a QFileDialog is to use the static
131functions. On Windows, these static functions will call the native
132Windows file dialog and on Mac OS X, these static function will call
133the native Mac OS X file dialog.
134<p> <pre>
135 <a href="qstring.html">QString</a> s = QFileDialog::<a href="#getOpenFileName">getOpenFileName</a>(
136 "/home",
137 "Images (*.png *.xpm *.jpg)",
138 this,
139 "open file dialog",
140 "Choose a file" );
141 </pre>
142
143<p> In the above example, a modal QFileDialog is created using a static
144function. The startup directory is set to "/home". The file filter
145is set to "Images (*.png *.xpm *.jpg)". The parent of the file dialog
146is set to <em>this</em> and it is given the identification name - "open file
147dialog". The caption at the top of file dialog is set to "Choose a
148file". If you want to use multiple filters, separate each one with
149<em>two</em> semi-colons, e.g.
150<pre>
151 "Images (*.png *.xpm *.jpg);;Text files (*.txt);;XML files (*.xml)"
152 </pre>
153
154<p> You can create your own QFileDialog without using the static
155functions. By calling <a href="#setMode">setMode</a>(), you can set what can be returned by
156the QFileDialog.
157<p> <pre>
158 QFileDialog* fd = new QFileDialog( this, "file dialog", TRUE );
159 fd-&gt;<a href="#setMode">setMode</a>( QFileDialog::<a href="#Mode-enum">AnyFile</a> );
160 </pre>
161
162<p> In the above example, the mode of the file dialog is set to <a href="#Mode-enum">AnyFile</a>, meaning that the user can select any file, or even specify a
163file that doesn't exist. This mode is useful for creating a "File Save
164As" file dialog. Use <a href="#Mode-enum">ExistingFile</a> if the user must select an
165existing file or <a href="#Mode-enum">Directory</a> if only a directory may be selected.
166(See the <a href="#Mode-enum">QFileDialog::Mode</a> enum for the complete list of modes.)
167<p> You can retrieve the dialog's mode with <a href="#mode">mode</a>(). Use <a href="#setFilter">setFilter</a>() to set
168the dialog's file filter, e.g.
169<p> <pre>
170 fd-&gt;setFilter( "Images (*.png *.xpm *.jpg)" );
171 </pre>
172
173<p> In the above example, the filter is set to "Images (*.png *.xpm
174*.jpg)", this means that only files with the extension <tt>png</tt>, <tt>xpm</tt>
175or <tt>jpg</tt> will be shown in the QFileDialog. You can apply
176several filters by using <a href="#setFilters">setFilters</a>() and add additional filters with
177<a href="#addFilter">addFilter</a>(). Use <a href="#setSelectedFilter">setSelectedFilter</a>() to select one of the filters
178you've given as the file dialog's default filter. Whenever the user
179changes the filter the <a href="#filterSelected">filterSelected</a>() signal is emitted.
180<p> The file dialog has two view modes, QFileDialog::List which simply
181lists file and directory names and QFileDialog::Detail which
182displays additional information alongside each name, e.g. file size,
183modification date, etc. Set the mode with <a href="#setViewMode">setViewMode</a>().
184<p> <pre>
185 fd-&gt;setViewMode( QFileDialog::<a href="#ViewMode-enum">Detail</a> );
186 </pre>
187
188<p> The last important function you will need to use when creating your
189own file dialog is <a href="#selectedFile">selectedFile</a>().
190<p> <pre>
191 <a href="qstring.html">QString</a> fileName;
192 if ( fd-&gt;exec() == QDialog::<a href="qdialog.html#DialogCode-enum">Accepted</a> )
193 fileName = fd-&gt;selectedFile();
194 </pre>
195
196<p> In the above example, a modal file dialog is created and shown. If
197the user clicked OK, then the file they selected is put in <tt>fileName</tt>.
198<p> If you are using the <a href="#Mode-enum">ExistingFiles</a> mode then you will need to use
199<a href="#selectedFiles">selectedFiles</a>() which will return the selected files in a <a href="qstringlist.html">QStringList</a>.
200<p> The dialog's working directory can be set with <a href="#setDir">setDir</a>(). The display
201of hidden files is controlled with <a href="#setShowHiddenFiles">setShowHiddenFiles</a>(). The dialog
202can be forced to re-read the directory with <a href="#rereadDir">rereadDir</a>() and re-sort
203the directory with <a href="#resortDir">resortDir</a>(). All the files in the current directory
204can be selected with <a href="#selectAll">selectAll</a>().
205<p> <h3> Creating and using preview widgets
206</h3>
207<a name="1"></a><p> There are two kinds of preview widgets that can be used with
208QFileDialogs: <em>content</em> preview widgets and <em>information</em> preview
209widgets. They are created and used in the same way except that the
210function names differ, e.g. <a href="#setContentsPreview">setContentsPreview</a>() and <a href="#setInfoPreview">setInfoPreview</a>().
211<p> A preview widget is a widget that is placed inside a QFileDialog so
212that the user can see either the contents of the file, or information
213about the file.
214<p> <pre>
215 class Preview : public <a href="qlabel.html">QLabel</a>, public QFilePreview
216 {
217 public:
218 Preview( <a href="qwidget.html">QWidget</a> *parent=0 ) : <a href="qlabel.html">QLabel</a>( parent ) {}
219
220 void previewUrl( const <a href="qurl.html">QUrl</a> &amp;u )
221 {
222 <a href="qstring.html">QString</a> path = u.<a href="qurl.html#path">path</a>();
223 <a href="qpixmap.html">QPixmap</a> pix( path );
224 if ( pix.<a href="qpixmap.html#isNull">isNull</a>() )
225 setText( "This is not a pixmap" );
226 else
227 setPixmap( pix );
228 }
229 };
230 </pre>
231
232<p> In the above snippet, we create a preview widget which inherits from
233<a href="qlabel.html">QLabel</a> and <a href="qfilepreview.html">QFilePreview</a>. File preview widgets <em>must</em> inherit from
234QFilePreview.
235<p> Inside the class we reimplement <a href="qfilepreview.html#previewUrl">QFilePreview::previewUrl</a>(), this is
236where we determine what happens when a file is selected. In the
237above example we only show a preview of the file if it is a valid
238pixmap. Here's how to make a file dialog use a preview widget:
239<p> <pre>
240 Preview* p = new Preview;
241
242 QFileDialog* fd = new QFileDialog( this );
243 fd-&gt;<a href="#setContentsPreviewEnabled">setContentsPreviewEnabled</a>( TRUE );
244 fd-&gt;<a href="#setContentsPreview">setContentsPreview</a>( p, p );
245 fd-&gt;<a href="#setPreviewMode">setPreviewMode</a>( QFileDialog::<a href="#PreviewMode-enum">Contents</a> );
246 fd-&gt;<a href="qdialog.html#show">show</a>();
247 </pre>
248
249<p> The first line creates an instance of our preview widget. We then
250create our file dialog and call <a href="#setContentsPreviewEnabled">setContentsPreviewEnabled</a>( TRUE ),
251this tell the file dialog to preview the contents of the currently
252selected file. We then call <a href="#setContentsPreview">setContentsPreview</a>() -- note that we pass
253the same preview widget twice. Finally, before showing the file
254dialog, we call <a href="#setPreviewMode">setPreviewMode</a>() setting the mode to <em>Contents</em> which
255will show the contents preview of the file that the user has selected.
256<p> If you create another preview widget that is used for displaying
257information about a file, create it in the same way as the contents
258preview widget and call <a href="#setInfoPreviewEnabled">setInfoPreviewEnabled</a>(), and
259<a href="#setInfoPreview">setInfoPreview</a>(). Then the user will be able to switch between the
260two preview modes.
261<p> For more information about creating a <a href="qfilepreview.html">QFilePreview</a> widget see
262<a href="qfilepreview.html">QFilePreview</a>.
