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. + + \code + QString s = QFileDialog::getOpenFileName( + "/home", + "Images (*.png *.xpm *.jpg)", + this, + "open file dialog", + "Choose a file" ); + \endcode + + 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 \e this 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 + \e two semi-colons, e.g. + \code + "Images (*.png *.xpm *.jpg);;Text files (*.txt);;XML files (*.xml)" + \endcode + + You can create your own QFileDialog without using the static + functions. By calling setMode(), you can set what can be returned by + the QFileDialog. + + \code + QFileDialog* fd = new QFileDialog( this, "file dialog", TRUE ); + fd->setMode( QFileDialog::AnyFile ); + \endcode + + In the above example, the mode of the file dialog is set to \c + AnyFile, 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 \c ExistingFile if the user must select an + existing file or \c Directory if only a directory may be selected. + (See the \l QFileDialog::Mode enum for the complete list of modes.) + + You can retrieve the dialog's mode with mode(). Use setFilter() to set + the dialog's file filter, e.g. + + \code + fd->setFilter( "Images (*.png *.xpm *.jpg)" ); + \endcode + + In the above example, the filter is set to "Images (*.png *.xpm + *.jpg)", this means that only files with the extension \c png, \c xpm + or \c jpg will be shown in the QFileDialog. You can apply + several filters by using setFilters() and add additional filters with + addFilter(). Use setSelectedFilter() to select one of the filters + you've given as the file dialog's default filter. Whenever the user + changes the filter the filterSelected() signal is emitted. + + 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 setViewMode(). + + \code + fd->setViewMode( QFileDialog::Detail ); + \endcode + + The last important function you will need to use when creating your + own file dialog is selectedFile(). + + \code + QString fileName; + if ( fd->exec() == QDialog::Accepted ) + fileName = fd->selectedFile(); + \endcode + + 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 \c + fileName. + + If you are using the \c ExistingFiles mode then you will need to use + selectedFiles() which will return the selected files in a QStringList. + + The dialog's working directory can be set with setDir(). The display + of hidden files is controlled with setShowHiddenFiles(). The dialog + can be forced to re-read the directory with rereadDir() and re-sort + the directory with resortDir(). All the files in the current directory + can be selected with selectAll(). + + \section1 Creating and using preview widgets + + There are two kinds of preview widgets that can be used with + QFileDialogs: \e content preview widgets and \e information preview + widgets. They are created and used in the same way except that the + function names differ, e.g. setContentsPreview() and setInfoPreview(). + + 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. + + \code + class Preview : public QLabel, public QFilePreview + { + public: + Preview( QWidget *parent=0 ) : QLabel( parent ) {} + + void previewUrl( const QUrl &u ) + { + QString path = u.path(); + QPixmap pix( path ); + if ( pix.isNull() ) + setText( "This is not a pixmap" ); + else + setPixmap( pix ); + } + }; + \endcode + + In the above snippet, we create a preview widget which inherits from + QLabel and QFilePreview. File preview widgets \e must inherit from + QFilePreview. + + Inside the class we reimplement QFilePreview::previewUrl(), 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: + + \code + Preview* p = new Preview; + + QFileDialog* fd = new QFileDialog( this ); + fd->setContentsPreviewEnabled( TRUE ); + fd->setContentsPreview( p, p ); + fd->setPreviewMode( QFileDialog::Contents ); + fd->show(); + \endcode + + The first line creates an instance of our preview widget. We then + create our file dialog and call setContentsPreviewEnabled( TRUE ), + this tell the file dialog to preview the contents of the currently + selected file. We then call setContentsPreview() -- note that we pass + the same preview widget twice. Finally, before showing the file + dialog, we call setPreviewMode() setting the mode to \e Contents which + will show the contents preview of the file that the user has selected. + + 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 setInfoPreviewEnabled(), and + setInfoPreview(). Then the user will be able to switch between the + two preview modes. + + For more information about creating a QFilePreview widget see + \l{QFilePreview}. + + <img src=qfiledlg-m.png> <img src=qfiledlg-w.png> + +*/ + + +/*! \enum QFileDialog::Mode + + 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. + + \value AnyFile The name of a file, whether it exists or not. + \value ExistingFile The name of a single existing file. + \value Directory The name of a directory.
