This widget works by putting a inside a . It exposes the interface, so you can use all of the functions on the file chooser dialog as well as those for . Similar to but in a dialog. Typical usage. In the simplest of cases, you can use the following code to select a file for opening: public class MainWindow: Gtk.Window { protected virtual void OnBtnLoadFileClicked(object sender, System.EventArgs e) { Gtk.FileChooserDialog fc= new Gtk.FileChooserDialog("Choose the file to open", this, FileChooserAction.Open, "Cancel",ResponseType.Cancel, "Open",ResponseType.Accept); if (fc.Run() == (int)ResponseType.Accept) { System.IO.FileStream file=System.IO.File.OpenRead(fc.Filename); file.Close(); } //Don't forget to call Destroy() or the FileChooserDialog window won't get closed. fc.Destroy(); } Gtk.Dialog Gtk.FileChooser Method System.Boolean Sets the current folder for the chooser from an URI. a , the URI to use a , true if the folder could be changed successfully, false otherwise The user will be shown the full contents of the current folder, plus user interface elements for navigating to other folders.

Constructor Protected constructor. a System.Obsolete Constructor Constructor for internal use. a , pointer to underlying C object. Property GLib.GType The of this object. a Property System.String The file chooser's current folder, if set from a URI. a Property Gtk.Widget An application-supplied widget to provide extra options to the user. a GLib.Property("extra-widget") Property System.String Property to represent the current name in the file selector, as if entered by the user. a Note that the name passed in here is a UTF-8 string rather than a filename. This function is meant for such uses as a suggested name in a "Save As..." dialog. Property Gtk.FileFilter The currently-applied file filter. a GLib.Property("filter") Property System.Boolean Sets whether only local files can be selected in the file selector. a If true (the default), then the selected file are files are guaranteed to be accessible through the operating systems native file file system and therefore the application only needs to worry about the filename functions in , like , rather than the URI functions like . GLib.Property("local-only") Property System.Boolean Sets whether the preview widget set by should be shown for the current filename. a When this property is set to false, the file chooser may display an internally generated preview of the current file or it may display no preview at all. GLib.Property("preview-widget-active") Property System.String Internal function; gets the filename that should be previewed in a custom preview. a Not for general programmer use. Property System.String The URI for the currently selected file in the file selector. a If multiple files are selected, one of the filenames will be returned at random. If the file chooser is in folder mode, this function returns the selected folder. Property System.Boolean Sets whether the file chooser should display a stock label with the name of the file that is being previewed; the default is true. a Applications that want to draw the whole preview area themselves should set this to false and display the name themselves in their preview widget. GLib.Property("use-preview-label") Property System.String The current filename selected by the file chooser. a Property System.String The URI that should be previewed in a custom preview widget. a Property System.Boolean Sets whether multiple files can be selected in the file selector. a This is only relevant if the action is set to be or . It cannot be set with either of the folder actions. GLib.Property("select-multiple") Property Gtk.Widget An application-supplied widget to use to display a custom preview of the currently selected file. a To implement a preview, after setting the preview widget, you connect to the signal, and check or on each change. If you can display a preview of the new file, update your widget and set the preview active using Otherwise, set the preview inactive. When there is no application-supplied preview widget, or the application-supplied preview widget is not active, the file chooser may display an internally generated preview of the current file or it may display no preview at all. GLib.Property("preview-widget") Property Gtk.FileChooserAction Sets the type of operation that that the chooser is performing; the user interface is adapted to suit the selected action. a For example, an option to create a new folder might be shown if the action is but not if the action is . GLib.Property("action") Property System.String The current folder for the file chooser, when the chooser has selected a local filename. a Property System.String[] The filenames selected by this widget. a Property System.String[] The URIs selected by this dialog. a Property Gtk.FileFilter[] The filters currently in use by this dialog for patterns of files to display. a Property System.String[] The shortcut folders currently in use for this dialog. a Property System.String[] The shortcut URIs currently allowed for this dialog. a Event System.EventHandler This event is raised every time the selected file changes. GLib.Signal("selection-changed") Event System.EventHandler This signal is emitted when the user "activates" a file in the file chooser. This event can happen by double-clicking on a file in the file list, or by pressing Enter. Normally you do not need to connect to this signal. It is used internally by the file chooser code to know when to activate the default button in the dialog. GLib.Signal("file-activated") Event System.EventHandler This signal is emitted when the preview in a file chooser should be regenerated. For example, this can happen when the currently selected file changes. You should use this signal if you want your file chooser to have a preview widget. Once you have installed a preview widget with , you should update it when this signal is emitted. You can use the properties or to get the name of the file to preview. Your widget may not be able to preview all kinds of files; your callback must set to inform the file chooser about whether the preview was generated successfully or not. TODO: insert example from gtkfilechooser-preview in gtk+ docs. GLib.Signal("update-preview") Event System.EventHandler This signal is emitted when the current folder in a file chooser changes. This event can happen due to the user performing some action that changes folders, such as selecting a bookmark or visiting a folder on the file list. It can also happen as a result of calling a function to explicitly change the current folder in a file chooser. Normally you do not need to connect to this signal, unless you need to keep track of which folder a file chooser is showing.

See . an action, for example save or open. a list of button text/response pairs for buttons to be added to the dialog, if desired. The pair format is , (see an example in overview section of ) By default, a comes with no buttons, so you'd better provide at least the most basics one (Save/Cancel or Open/Cancel) or your user won't be able to do anything apart from closing the dialog ( closing the dialog returns .None ) Constructor System.ParamArray Creates a file chooser dialog with a specific file chooser backend a , the backend name a title a parent for the dialog, or . an action, for example save or open. a list of button text/response pairs for buttons to be added to the dialog, if desired. This is especially useful if you use to allow non-local files and you use a more expressive vfs, such as gnome-vfs, to load files. Property System.Boolean Indicates if Hidden files and directories should be visible. a GLib.Property("show-hidden") Event GLib.Signal("confirm-overwrite") Gtk.ConfirmOverwriteHandler Indicates a file overwrite has been requested. This event is raised when the user has selected a file name that already exists and the file chooser is in mode. Most applications just need to turn on the property and they will automatically get a stock confirmation dialog. Applications which need to customize this behavior should do that, and also connect to this event. A connected to this event must set to the value indicating the action to take. If the handler determines that the user wants to select a different filename, it should return . If it determines that the user is satisfied with his choice of file name, it should return . On the other hand, if it determines that the stock confirmation dialog should be used, it should return . Method Gtk.FileChooserConfirmation Default handler for the event. To be added. Override this method in a subclass to provide a default handler for the event. Property GLib.Property("do-overwrite-confirmation") System.Boolean Enables Overwrite Confirmation in the dialog. if confirmation should be performed.
