<hr><a name="details"></a><h2>Detailed Description</h2>
The QFileDialog class provides dialogs that allow users to select files or directories.
<p> The QFileDialog class enables a user to traverse their file system in
order to select one or many files or a directory.
<p> The easiest way to create a QFileDialog is to use the static
functions. On Windows, these static functions will call the native
Windows file dialog and on Mac OS X, these static function will call
the native Mac OS X file dialog.
<p> <pre>
<a href="qstring.html">QString</a> s = QFileDialog::<a href="#getOpenFileName">getOpenFileName</a>( "/home",
"Images (*.png *.xpm *.jpg)",
this,
"open file dialog"
"Choose a file" );
</pre>
<p> In the above example, a modal QFileDialog is created using a static
function. The startup directory is set to "/home". The file filter
is set to "Images (*.png *.xpm *.jpg)". The parent of the file dialog
is set to <em>this</em> and it is given the identification name - "open file
dialog". The caption at the top of file dialog is set to "Choose a
file".
<p> You can create your own QFileDialog without using the static
functions. By calling <a href="#setMode">setMode</a>(), you can set what can be returned by
the QFileDialog.
<p> <pre>
QFileDialog* fd = new QFileDialog( this, "file dialog", TRUE );
fd-><a href="#setMode">setMode</a>( QFileDialog::<a href="#Mode-enum">AnyFile</a> );
</pre>
<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
file that doesn't exist. This mode is useful for creating a "File Save
As" file dialog. Use <a href="#Mode-enum">ExistingFile</a> if the user must select an
existing file or <a href="#Mode-enum">Directory</a> if only a directory must be selected.
(See the <a href="#Mode-enum">QFileDialog::Mode</a> enum for the complete list of modes.)
<p> You can retrieve the dialog's mode with <a href="#mode">mode</a>(). Use <a href="#setFilter">setFilter</a>() to set
the dialog's file filter, e.g.
<p> <pre>
fd->setFilter( "Images (*.png *.xpm *.jpg)" );
</pre>
<p> In the above example, the filter is set to "Images (*.png *.xpm
*.jpg)", this means that only files with the extension <tt>png</tt>, <tt>xpm</tt>
or <tt>jpg</tt> files will be visible in the QFileDialog. You can apply
several filters by using <a href="#setFilters">setFilters</a>() and add additional filters with
<a href="#addFilter">addFilter</a>(). Use <a href="#setSelectedFilter">setSelectedFilter</a>() to select one of the filters
you've given as the file dialog's default filter. Whenever the user
changes the filter the <a href="#filterSelected">filterSelected</a>() signal is emitted.
<p> The file dialog has two view modes, QFileDialog::List which simply
lists file and directory names and QFileDialog::Detail which
displays additional information beside each name, e.g. file size,
modification date, etc. Set the move with <a href="#setViewMode">setViewMode</a>().
<p> <pre>
fd->setViewMode( QFileDialog::<a href="#ViewMode-enum">Detail</a> );
</pre>
<p> The last important function you will need to use when creating your
own file dialog is <a href="#selectedFile">selectedFile</a>().
<p> <pre>
<a href="qstring.html">QString</a> fileName;
if ( fd->exec() == QDialog::<a href="qdialog.html#DialogCode-enum">Accepted</a> )
fileName = fd->selectedFile();
</pre>
<p> In the above example, a modal file dialog is created and shown. If
the user clicked OK, then the file they selected is put in <tt>fileName</tt>.
<p> If you are using the <a href="#Mode-enum">ExistingFiles</a> mode then you will need to use
<a href="#selectedFiles">selectedFiles</a>() which will return the selected files in a <a href="qstringlist.html">QStringList</a>.
<p> The dialog's working directory can be set with <a href="#setDir">setDir</a>(). The display
of hidden files is controlled with <a href="#setShowHiddenFiles">setShowHiddenFiles</a>(). The dialog
can be forced to re-read the directory with <a href="#rereadDir">rereadDir</a>() and re-sort
the directory with <a href="#resortDir">resortDir</a>(). All the files in the current directory
can be selected with <a href="#selectAll">selectAll</a>().
<p> <h3>Creating and using preview widgets</h3>
<p> There are two kinds of preview widgets that can be used with
QFileDialogs: <em>content</em> preview widgets and <em>information</em> preview
widgets. They are created and used in the same way except that the
function names differ, e.g. <a href="#setContentsPreview">setContentsPreview</a>() and <a href="#setInfoPreview">setInfoPreview</a>().
<p> A preview widget is a widget that is placed inside a QFileDialog so
that the user can see either the contents of the file, or information
about the file.
<p> <pre>
class Preview : public <a href="qlabel.html">QLabel</a>, public QFilePreview
{
public:
Preview( <a href="qwidget.html">QWidget</a> *parent=0 ) : <a href="qlabel.html">QLabel</a>( parent ) {}
void previewUrl( const <a href="qurl.html">QUrl</a> &u )
{
<a href="qstring.html">QString</a> path = u.<a href="qurl.html#path">path</a>();
<a href="qpixmap.html">QPixmap</a> pix( path );
if ( pix.<a href="qpixmap.html#isNull">isNull</a>() )
setText( "This is not a pixmap" );
else
setPixmap( pix );
}
};
</pre>
<p> In the above snippet, we create a preview widget which inherits from
<a href="qlabel.html">QLabel</a> and <a href="qfilepreview.html">QFilePreview</a>. File preview widgets <em>must</em> inherit from
QFilePreview.
<p> Inside the class we reimplement <a href="qfilepreview.html#previewUrl">QFilePreview::previewUrl</a>(), this is
where we determine what happens when a file is selected. In the case
above we only show a preview of the file if it is a valid pixmap.
Now we tell a file dialog that we have a preview widget that we want
it to use.
<p> <pre>
Preview* p = new Preview;
QFileDialog* fd = new QFileDialog( this );
fd-><a href="#setContentsPreviewEnabled">setContentsPreviewEnabled</a>( TRUE );
fd-><a href="#setContentsPreview">setContentsPreview</a>( p, p );
fd-><a href="#setPreviewMode">setPreviewMode</a>( QFileDialog::<a href="#PreviewMode-enum">Contents</a> );
fd-><a href="qdialog.html#show">show</a>();
</pre>
<p> The first line creates an instance of our preview widget. We then
create our file dialog and call <a href="#setContentsPreviewEnabled">setContentsPreviewEnabled</a>( TRUE ),
this tell the file dialog to preview the contents of the currently
selected file. We then call <a href="#setContentsPreview">setContentsPreview</a>() -- note that we pass
the same preview widget twice. Finally, before showing the file
dialog, we call <a href="#setPreviewMode">setPreviewMode</a>() setting the mode to <em>Contents</em> which
will show the contents the file that the user has selected.
<p> If you create another preview widget that is used for displaying
information about a file, create it in the same way as we have the
contents preview widget and call <a href="#setInfoPreviewEnabled">setInfoPreviewEnabled</a>(), and
<a href="#setInfoPreview">setInfoPreview</a>(). Then the user will be able to switch between the
two preview modes.
<p> For more information about creating a <a href="qfilepreview.html">QFilePreview</a> widget see QFilePreview.

<p> This function creates a modal file dialog with parent <em>parent</em>,
and name <em>name</em>. If a parent is specified the dialog
will be shown centered over the parent.
<p> The dialog's working directory is set to <em>dir</em>, and the caption is
set to <em>caption</em>. Either of these may be <a href="qstring.html#QString-null">QString::null</a> in which case
the current directory and a default caption will be used respectively.
<p> If <em>dirOnly</em> is TRUE, then only directories will be shown in
the file dialog; otherwise both directories and files will be shown.
<p> Under Unix/X11, the normal behavior of the file dialog is to resolve
and follow symlinks. For example, if /usr/tmp is a symlink to /var/tmp,
the file dialog will change to /var/tmp after entering /usr/tmp.
If <em>resolveSymlinks</em> is FALSE, the file dialog will treat
symlinks as regular directories.

<p>This property holds the preview mode for the file dialog.
<p>If you set the mode to be a mode other than <em>NoPreview</em>, then use

widget to your preview widget and enable the preview widget(s) with
<a href="#setInfoPreviewEnabled">setInfoPreviewEnabled</a>() or <a href="#setContentsPreviewEnabled">setContentsPreviewEnabled</a>().
<p> <p>See also <a href="#infoPreview-prop">infoPreview</a>, <a href="#contentsPreview-prop">contentsPreview</a> and <a href="#viewMode-prop">viewMode</a>.
<p>Set this property's value with <a href="#setPreviewMode">setPreviewMode</a>() and get this property's value with <a href="#previewMode">previewMode</a>().
<h3 class=fn><a href="qstring.html">QString</a> <a name="selectedFile-prop"></a>selectedFile</h3>
<p>This property holds the name of the selected file.
<p>If a file was selected selectedFile contains the file's name including

<p>If one or more files were selected selectedFiles contains the
names of the selected files including their absolute paths. If no
files were selected or the mode wasn't ExistingFiles selectedFiles

<a href="#Mode-enum">ExistingFile</a>, <a href="#Mode-enum">Directory</a> or <a href="#Mode-enum">DirectoryOnly</a>.
<p> Note that if you want to iterate over the list, you should
iterate over a copy, e.g.
<pre>
<a href="qstringlist.html">QStringList</a> list = myFileDialog.selectedFiles();
QStringList::Iterator it = list.<a href="qvaluelist.html#begin">begin</a>();
while( it != list.<a href="qvaluelist.html#end">end</a>() ) {
myProcessing( *it );
++it;
}
</pre>
<p> <p>See also <a href="#selectedFile-prop">selectedFile</a>, <a href="#selectedFilter-prop">selectedFilter</a> and <a href="qvaluelist.html#empty">QValueList::empty</a>().

<h3 class=fn><a href="qfiledialog.html#ViewMode-enum">ViewMode</a> <a name="viewMode-prop"></a>viewMode</h3>
<p>This property holds the file dialog's view mode.
<p>If you set the view mode to be <em>Detail</em> (the default), then you
