The TQFileDialog class provides dialogs that allow users to select files or directories.


<p> The TQFileDialog 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 TQFileDialog 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="tqstring.html">TQString</a> s = TQFileDialog::<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 TQFileDialog 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". If you want to use multiple filters, separate each one with
<em>two</em> semi-colons, e.g.
<pre>
  "Images (*.png *.xpm *.jpg);;Text files (*.txt);;XML files (*.xml)"
  </pre>
 
<p> You can create your own TQFileDialog without using the static
functions. By calling <a href="#setMode">setMode</a>(), you can set what can be returned by
the TQFileDialog.
<p> <pre>
    TQFileDialog* fd = new TQFileDialog( this, "file dialog", TRUE );
    fd-&gt;<a href="#setMode">setMode</a>( TQFileDialog::<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 may be selected.
(See the <a href="#Mode-enum">TQFileDialog::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-&gt;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> will be shown in the TQFileDialog. 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, TQFileDialog::List which simply
lists file and directory names and TQFileDialog::Detail which
displays additional information alongside each name, e.g. file size,
modification date, etc. Set the mode with <a href="#setViewMode">setViewMode</a>().
<p> <pre>
    fd-&gt;setViewMode( TQFileDialog::<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="tqstring.html">TQString</a> fileName;
    if ( fd-&gt;exec() == TQDialog::<a href="tqdialog.html#DialogCode-enum">Accepted</a> )
        fileName = fd-&gt;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="tqstringlist.html">TQStringList</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>
<a name="1"></a><p> There are two kinds of preview widgets that can be used with
TQFileDialogs: <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 TQFileDialog so
that the user can see either the contents of the file, or information
about the file.
<p> <pre>
    class Preview : public <a href="tqlabel.html">TQLabel</a>, public TQFilePreview
    {
    public:
        Preview( <a href="tqwidget.html">TQWidget</a> *parent=0 ) : <a href="tqlabel.html">TQLabel</a>( parent ) {}

        void previewUrl( const <a href="tqurl.html">TQUrl</a> &amp;u )
        {
            <a href="tqstring.html">TQString</a> path = u.<a href="tqurl.html#path">path</a>();
            <a href="tqpixmap.html">TQPixmap</a> pix( path );
            if ( pix.<a href="tqpixmap.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="tqlabel.html">TQLabel</a> and <a href="tqfilepreview.html">TQFilePreview</a>. File preview widgets <em>must</em> inherit from
TQFilePreview.
<p> Inside the class we reimplement <a href="tqfilepreview.html#previewUrl">TQFilePreview::previewUrl</a>(), this is
where we determine what happens when a file is selected. In the
above example we only show a preview of the file if it is a valid
pixmap. Here's how to make a file dialog use a preview widget:
<p> <pre>
    Preview* p = new Preview;

    TQFileDialog* fd = new TQFileDialog( this );
    fd-&gt;<a href="#setContentsPreviewEnabled">setContentsPreviewEnabled</a>( TRUE );
    fd-&gt;<a href="#setContentsPreview">setContentsPreview</a>( p, p );
    fd-&gt;<a href="#setPreviewMode">setPreviewMode</a>( TQFileDialog::<a href="#PreviewMode-enum">Contents</a> );
    fd-&gt;<a href="tqdialog.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 preview of 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 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.

This is a convenience static function that will return an existing directory
selected by the user.
<p> <pre>
    <a href="tqstring.html">TQString</a> s = TQFileDialog::<a href="#getExistingDirectory">getExistingDirectory</a>(
                    "/home",
                    this,
                    "get existing directory",
                    "Choose a directory",
                    TRUE );
  </pre>
 
<p> This function creates a modal file dialog called <em>name</em>, with
parent, <em>parent</em>. If parent is not 0, 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="tqstring.html#TQString-null">TQString::null</a> in which case
the current directory and a default caption will be used respectively.
<p> Note on Windows that if <em>dir</em> is TQString::null then the dialog's working
directory will be set to the user's My Documents directory.
<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> Under Windows and Mac OS X, this static function will use the native
file dialog and not a TQFileDialog, unless the style of the application
is set to something other than the native style. (Note that on Windows the
dialog will spin a blocking modal event loop that will not dispatch any
TQTimers and if parent is not 0 then it will position the dialog just under
the parent's titlebar).

<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.

    TQStringList::Iterator it = list.<a href="tqvaluelist.html#begin">begin</a>();
    while( it != list.<a href="tqvaluelist.html#end">end</a>() ) {
        myProcessing( *it );
        ++it;
    }
    </pre>
