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". 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 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 may 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> will be shown 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 alongside each name, e.g. file size, +modification date, etc. Set the mode 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> +<a name="1"></a><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 +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; + + 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 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. +<p> For more information about creating a <a href="qfilepreview.html">QFilePreview</a> widget see +<a href="qfilepreview.html">QFilePreview</a>. +<p> <img src=qfiledlg-m.png> <img src=qfiledlg-w.png> +<p> <p>See also <a href="dialogs.html">Dialog Classes</a>. + +<hr><h2>Member Type Documentation</h2> +<h3 class=fn><a name="Mode-enum"></a>QFileDialog::Mode</h3> +<p> This enum is used to indicate what the user may select in the file +dialog, i.e. what the dialog will return if the user clicks OK. +<ul> +<li><tt>QFileDialog::AnyFile</tt> - The name of a file, whether it exists or not. +<li><tt>QFileDialog::ExistingFile</tt> - The name of a single existing file. +<li><tt>QFileDialog::Directory</tt> - The name of a directory.
