Description

FileChooser is an interface that can be implemented by file selection widgets. In GTK+, the main objects that implement this interface are FileChooserWidget, FileChooserDialog, and FileChooserButton. You do not need to write an object that implements the FileChooser interface unless you are trying to adapt an existing file selector to expose a standard programming interface.

FileChooser allows for shortcuts to various places in the filesystem. In the default implementation these are displayed in the left pane. It may be a bit confusing at first that these shortcuts come from various sources and in various flavours, so lets explain the terminology here:

  • Bookmarks: are created by the user, by dragging folders from the right pane to the left pane, or by using the “Add”. Bookmarks can be renamed and deleted by the user.
  • Shortcuts: can be provided by the application. For example, a Paint program may want to add a shortcut for a Clipart folder. Shortcuts cannot be modified by the user.
  • Volumes: are provided by the underlying filesystem abstraction. They are the “roots” of the filesystem.

File Names and Encodings

When the user is finished selecting files in a FileChooser, your program can get the selected names either as filenames or as URIs. For URIs, the normal escaping rules are applied if the URI contains non-ASCII characters. However, filenames are always returned in the character set specified by the G_FILENAME_ENCODING environment variable. Please see the GLib documentation for more details about this variable.

This means that while you can pass the result of fileChooserGetFilename to open() or fopen(), you may not be able to directly set it as the text of a Label widget unless you convert it first to UTF-8, which all GTK+ widgets expect. You should use filenameToUtf8 to convert filenames into strings that can be passed to GTK+ widgets.

Adding a Preview Widget

You can add a custom preview widget to a file chooser and then get notification about when the preview needs to be updated. To install a preview widget, use fileChooserSetPreviewWidget. Then, connect to the FileChooser::update-preview signal to get notified when you need to update the contents of the preview.

Your callback should use fileChooserGetPreviewFilename to see what needs previewing. Once you have generated the preview for the corresponding file, you must call fileChooserSetPreviewWidgetActive with a boolean flag that indicates whether your callback could successfully generate a preview.

## {gtkfilechooser-preview}

C code

{
  GtkImage *preview;

  ...

  preview = gtk_image_new ();

  gtk_file_chooser_set_preview_widget (my_file_chooser, preview);
  g_signal_connect (my_file_chooser, "update-preview",
		    G_CALLBACK (update_preview_cb), preview);
}

static void
update_preview_cb (GtkFileChooser *file_chooser, gpointer data)
{
  GtkWidget *preview;
  char *filename;
  GdkPixbuf *pixbuf;
  gboolean have_preview;

  preview = GTK_WIDGET (data);
  filename = gtk_file_chooser_get_preview_filename (file_chooser);

  pixbuf = gdk_pixbuf_new_from_file_at_size (filename, 128, 128, NULL);
  have_preview = (pixbuf != NULL);
  g_free (filename);

  gtk_image_set_from_pixbuf (GTK_IMAGE (preview), pixbuf);
  if (pixbuf)
    g_object_unref (pixbuf);

  gtk_file_chooser_set_preview_widget_active (file_chooser, have_preview);
}

Adding Extra Widgets

You can add extra widgets to a file chooser to provide options that are not present in the default design. For example, you can add a toggle button to give the user the option to open a file in read-only mode. You can use fileChooserSetExtraWidget to insert additional widgets in a file chooser.

An example for adding extra widgets:

C code


  GtkWidget *toggle;

  ...

  toggle = gtk_check_button_new_with_label ("Open file read-only");
  gtk_widget_show (toggle);
  gtk_file_chooser_set_extra_widget (my_file_chooser, toggle);
}

If you want to set more than one extra widget in the file chooser, you can a container such as a Box or a Grid and include your widgets in it. Then, set the container as the whole extra widget.

Synopsis

Exported types

Methods

addChoice

fileChooserAddChoice Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a) 
=> a

chooser: a FileChooser

-> Text

id: id for the added choice

-> Text

label: user-visible label for the added choice

-> Text

options: ids for the options of the choice, or Nothing for a boolean choice

-> Text

optionLabels: user-visible labels for the options, must be the same length as options

-> m () 

Adds a 'choice' to the file chooser. This is typically implemented as a combobox or, for boolean choices, as a checkbutton. You can select a value using fileChooserSetChoice before the dialog is shown, and you can obtain the user-selected value in the ::response signal handler using fileChooserGetChoice.

Compare fileChooserSetExtraWidget.

Since: 3.22

addFilter

fileChooserAddFilter Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a, IsFileFilter b) 
=> a

chooser: a FileChooser

-> b

filter: a FileFilter

-> m () 

Adds filter to the list of filters that the user can select between. When a filter is selected, only files that are passed by that filter are displayed.

Note that the chooser takes ownership of the filter, so you have to ref and sink it if you want to keep a reference.

Since: 2.4

addShortcutFolder

fileChooserAddShortcutFolder Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a) 
=> a

chooser: a FileChooser

-> [Char]

folder: filename of the folder to add

-> m ()

(Can throw GError)

Adds a folder to be displayed with the shortcut folders in a file chooser. Note that shortcut folders do not get saved, as they are provided by the application. For example, you can use this to add a “/usr/share/mydrawprogram/Clipart” folder to the volume list.

Since: 2.4

addShortcutFolderUri

fileChooserAddShortcutFolderUri Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a) 
=> a

chooser: a FileChooser

-> Text

uri: URI of the folder to add

-> m ()

Gets the type of operation that the file chooser is performing; see fileChooserSetAction.

Since: 2.4

getChoice

fileChooserGetChoice Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a) 
=> a

chooser: a FileChooser

-> Text

id: the ID of the choice to get

Since: 2.18

getCurrentFolder

fileChooserGetCurrentFolder Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a) 
=> a

chooser: a FileChooser

-> m (Maybe [Char])

Returns: the full path of the current folder, or Nothing if the current path cannot be represented as a local filename. Free with free. This function will also return Nothing if the file chooser was unable to load the last folder that was requested from it; for example, as would be for calling fileChooserSetCurrentFolder on a nonexistent folder.

Gets the current folder of chooser as a local filename. See fileChooserSetCurrentFolder.

Note that this is the folder that the file chooser is currently displaying (e.g. "/home/username/Documents"), which is not the same as the currently-selected folder if the chooser is in FileChooserActionSelectFolder mode (e.g. "/home/username/Documents/selected-folder/". To get the currently-selected folder in that mode, use fileChooserGetUri as the usual way to get the selection.

Since: 2.4

getCurrentFolderFile

fileChooserGetCurrentFolderFile Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a) 
=> a

chooser: a FileChooser

-> m File

Returns: the File for the current folder.

Gets the current folder of chooser as File. See fileChooserGetCurrentFolderUri.

Since: 2.14

getCurrentFolderUri

fileChooserGetCurrentFolderUri Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a) 
=> a

chooser: a FileChooser

-> m (Maybe Text)

Returns: the URI for the current folder. Free with free. This function will also return Nothing if the file chooser was unable to load the last folder that was requested from it; for example, as would be for calling fileChooserSetCurrentFolderUri on a nonexistent folder.

Gets the current folder of chooser as an URI. See fileChooserSetCurrentFolderUri.

Note that this is the folder that the file chooser is currently displaying (e.g. "file:///home/username/Documents"), which is not the same as the currently-selected folder if the chooser is in FileChooserActionSelectFolder mode (e.g. "file:///home/username/Documents/selected-folder/". To get the currently-selected folder in that mode, use fileChooserGetUri as the usual way to get the selection.

Since: 2.4

getCurrentName

fileChooserGetCurrentName Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a) 
=> a

chooser: a FileChooser

-> m Text

Returns: The raw text from the file chooser’s “Name” entry. Free this with free. Note that this string is not a full pathname or URI; it is whatever the contents of the entry are. Note also that this string is in UTF-8 encoding, which is not necessarily the system’s encoding for filenames.

Gets the current name in the file selector, as entered by the user in the text entry for “Name”.

This is meant to be used in save dialogs, to get the currently typed filename when the file itself does not exist yet. For example, an application that adds a custom extra widget to the file chooser for “file format” may want to change the extension of the typed filename based on the chosen format, say, from “.jpg” to “.png”.

-> [Char]

name: the filename to use, as a UTF-8 string

-> m () 

Sets the current name in the file selector, as if entered by the user. 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. You can pass “Untitled.doc” or a similarly suitable suggestion for the name.

If you want to preselect a particular existing file, you should use fileChooserSetFilename or fileChooserSetUri instead. Please see the documentation for those functions for an example of using fileChooserSetCurrentName as well.

Since: 2.4

setDoOverwriteConfirmation

fileChooserSetDoOverwriteConfirmation Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a) 
=> a

chooser: a FileChooser

-> Bool

doOverwriteConfirmation: whether to confirm overwriting in save mode

-> m () 

Sets whether a file chooser in FileChooserActionSave mode will present a confirmation dialog if the user types a file name that already exists. This is False by default.

If set to True, the chooser will emit the FileChooser::confirm-overwrite signal when appropriate.

If all you need is the stock confirmation dialog, set this property to True. You can override the way confirmation is done by actually handling the FileChooser::confirm-overwrite signal; please refer to its documentation for the details.

Since: 2.8

setExtraWidget

fileChooserSetExtraWidget Source #

Arguments

Since: 2.4

setFile

data FileChooserSetFileMethodInfo Source #

Instances

((~) * signature (b -> m ()), MonadIO m, IsFileChooser a, IsFile b) => MethodInfo * FileChooserSetFileMethodInfo a signature Source # 

fileChooserSetFile Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a, IsFile b) 
=> a

chooser: a FileChooser

-> b

file: the File to set as current

-> m ()

(Can throw GError)

Sets file as the current filename for the file chooser, by changing to the file’s parent folder and actually selecting the file in list. If the chooser is in FileChooserActionSave mode, the file’s base name will also appear in the dialog’s file name entry.

If the file name isn’t in the current folder of chooser, then the current folder of chooser will be changed to the folder containing filename. This is equivalent to a sequence of fileChooserUnselectAll followed by fileChooserSelectFilename.

Note that the file must exist, or nothing will be done except for the directory change.

If you are implementing a save dialog, you should use this function if you already have a file name to which the user may save; for example, when the user opens an existing file and then does Save As... If you don’t have a file name already — for example, if the user just created a new file and is saving it for the first time, do not call this function. Instead, use something similar to this:

C code

if (document_is_new)
  {
    // the user just created a new document
    gtk_file_chooser_set_current_folder_file (chooser, default_file_for_saving);
    gtk_file_chooser_set_current_name (chooser, "Untitled document");
  }
else
  {
    // the user edited an existing document
    gtk_file_chooser_set_file (chooser, existing_file);
  }

Since: 2.14

setFilename

fileChooserSetFilename Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a) 
=> a

chooser: a FileChooser

-> [Char]

filename: the filename to set as current

-> m Bool

Returns: Not useful.

Sets filename as the current filename for the file chooser, by changing to the file’s parent folder and actually selecting the file in list; all other files will be unselected. If the chooser is in FileChooserActionSave mode, the file’s base name will also appear in the dialog’s file name entry.

Note that the file must exist, or nothing will be done except for the directory change.

You should use this function only when implementing a save dialog for which you already have a file name to which the user may save. For example, when the user opens an existing file and then does Save As... to save a copy or a modified version. If you don’t have a file name already — for example, if the user just created a new file and is saving it for the first time, do not call this function. Instead, use something similar to this:

C code

if (document_is_new)
  {
    // the user just created a new document
    gtk_file_chooser_set_current_name (chooser, "Untitled document");
  }
else
  {
    // the user edited an existing document
    gtk_file_chooser_set_filename (chooser, existing_filename);
  }

In the first case, the file chooser will present the user with useful suggestions as to where to save his new file. In the second case, the file’s existing location is already known, so the file chooser will use it.

setFilter

fileChooserSetFilter Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a, IsFileFilter b) 
=> a

chooser: a FileChooser

-> b

filter: a FileFilter

-> m () 

Sets the current filter; only the files that pass the filter will be displayed. If the user-selectable list of filters is non-empty, then the filter should be one of the filters in that list. Setting the current filter when the list of filters is empty is useful if you want to restrict the displayed set of files without letting the user change it.

setLocalOnly

fileChooserSetLocalOnly Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a) 
=> a

chooser: a FileChooser

-> Bool

localOnly: True if only local files can be selected

-> m () 

Sets whether only local files can be selected in the file selector. If localOnly is True (the default), then the selected file or files are guaranteed to be accessible through the operating systems native file system and therefore the application only needs to worry about the filename functions in FileChooser, like fileChooserGetFilename, rather than the URI functions like fileChooserGetUri,

On some systems non-native files may still be available using the native filesystem via a userspace filesystem (FUSE).

setPreviewWidget

fileChooserSetPreviewWidget Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a, IsWidget b) 
=> a

chooser: a FileChooser

-> b

previewWidget: widget for displaying preview.

-> m () 

Sets an application-supplied widget to use to display a custom preview of the currently selected file. To implement a preview, after setting the preview widget, you connect to the FileChooser::update-preview signal, and call fileChooserGetPreviewFilename or fileChooserGetPreviewUri on each change. If you can display a preview of the new file, update your widget and set the preview active using fileChooserSetPreviewWidgetActive. 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 will display no preview at all.

Since: 2.4

setPreviewWidgetActive

fileChooserSetPreviewWidgetActive Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a) 
=> a

chooser: a FileChooser

-> Bool

active: whether to display the user-specified preview widget

-> m () 

Sets whether the preview widget set by fileChooserSetPreviewWidget should be shown for the current filename. When active 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. See fileChooserSetPreviewWidget for more details.

Since: 2.4

setSelectMultiple

fileChooserSetSelectMultiple Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a) 
=> a

chooser: a FileChooser

-> Bool

selectMultiple: True if multiple files can be selected.

-> m () 

Sets whether multiple files can be selected in the file selector. This is only relevant if the action is set to be FileChooserActionOpen or FileChooserActionSelectFolder.

Since: 2.4

setShowHidden

fileChooserSetShowHidden Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a) 
=> a

chooser: a FileChooser

-> Bool

showHidden: True if hidden files and folders should be displayed.

-> m () 

Sets whether hidden files and folders are displayed in the file selector.

Since: 2.6

setUri

fileChooserSetUri Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a) 
=> a

chooser: a FileChooser

-> Text

uri: the URI to set as current

-> m Bool

Returns: Not useful.

Sets the file referred to by uri as the current file for the file chooser, by changing to the URI’s parent folder and actually selecting the URI in the list. If the chooser is FileChooserActionSave mode, the URI’s base name will also appear in the dialog’s file name entry.

Note that the URI must exist, or nothing will be done except for the directory change.

You should use this function only when implementing a save dialog for which you already have a file name to which the user may save. For example, when the user opens an existing file and then does Save As... to save a copy or a modified version. If you don’t have a file name already — for example, if the user just created a new file and is saving it for the first time, do not call this function. Instead, use something similar to this:

C code

if (document_is_new)
  {
    // the user just created a new document
    gtk_file_chooser_set_current_name (chooser, "Untitled document");
  }
else
  {
    // the user edited an existing document
    gtk_file_chooser_set_uri (chooser, existing_uri);
  }

In the first case, the file chooser will present the user with useful suggestions as to where to save his new file. In the second case, the file’s existing location is already known, so the file chooser will use it.

setUsePreviewLabel

fileChooserSetUsePreviewLabel Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a) 
=> a

chooser: a FileChooser

-> Bool

useLabel: whether to display a stock label with the name of the previewed file

-> m () 

Sets whether the file chooser should display a stock label with the name of the file that is being previewed; the default is True. Applications that want to draw the whole preview area themselves should set this to False and display the name themselves in their preview widget.

unselectAll

fileChooserUnselectAll Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a) 
=> a

chooser: a FileChooser

-> m () 

Unselects all the files in the current folder of a file chooser.

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a, IsFile b) 
=> a

chooser: a FileChooser

-> b

Since: 2.14

unselectFilename

fileChooserUnselectFilename Source #

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a) 
=> a

chooser: a FileChooser

-> [Char]

filename: the filename to unselect

-> m () 

Unselects a currently selected filename. If the filename is not in the current directory, does not exist, or is otherwise not currently selected, does nothing.

Since: 2.4

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a) 
=> a

chooser: a FileChooser

-> Text

uri: the URI to unselect

-> m ()
