GI.Gtk.Interfaces.FileChooser

FileChooser is an interface that can be implemented by file selection widgets. In GTK, the main objects that implement this interface are FileChooserWidget and FileChooserDialog. 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 filenames as GFiles.

Adding options

You can add extra widgets to a file chooser to provide options that are not present in the default design, by using fileChooserAddChoice. Each choice has an identifier and a user visible label; additionally, each choice can have multiple options. If a choice has no option, it will be rendered as a check button with the given label; if a choice has options, it will be rendered as a combo box.

addChoice

fileChooserAddChoice

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

-> Maybe [Text]

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

-> Maybe [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.

addFilter

fileChooserAddFilter

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 if it is floating, so you have to ref and sink it if you want to keep a reference.

addShortcutFolder

fileChooserAddShortcutFolder

Arguments

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

=> a

chooser: a FileChooser

-> b

folder: a File for the folder to add

Gets the currently selected option in the 'choice' with the given ID.

getCreateFolders

fileChooserGetCreateFolders

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a)

=> a

chooser: a FileChooser

-> m Bool

Returns: True if the Create Folder button should be displayed.

Gets whether file chooser will offer to create new folders. See fileChooserSetCreateFolders.

getCurrentFolder

fileChooserGetCurrentFolder

Arguments

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.

getFile

fileChooserGetFile

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a)

=> a

chooser: a FileChooser

-> m File

Returns: a selected File. You own the returned file; use objectUnref to release it.

If the file chooser is in folder mode, this function returns the selected folder.

getFiles

fileChooserGetFiles

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a)

=> a

chooser: a FileChooser

-> m ListModel

Returns: a list model containing a File for each selected file and subfolder in the current folder. Free the returned list with objectUnref.

Lists all the selected files and subfolders in the current folder of chooser as File.

getFilter

fileChooserGetFilter

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a)

=> a

chooser: a FileChooser

getSelectMultiple

fileChooserGetSelectMultiple

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a)

Removes a folder from the shortcut folders in a file chooser.

setAction

fileChooserSetAction

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a)

=> a

chooser: a FileChooser

-> FileChooserAction

action: the action that the file selector is performing

-> m ()

Sets the type of operation that the chooser is performing; the user interface is adapted to suit the selected action. For example, an option to create a new folder might be shown if the action is FileChooserActionSave but not if the action is FileChooserActionOpen.

setChoice

fileChooserSetChoice

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a)

=> a

chooser: a FileChooser

-> Text

id: the ID of the choice to set

-> Text

option: the ID of the option to select

-> m ()

Selects an option in a 'choice' that has been added with fileChooserAddChoice. For a boolean choice, the possible options are "true" and "false".

setCreateFolders

fileChooserSetCreateFolders

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a)

=> a

chooser: a FileChooser

-> Bool

createFolders: True if the Create Folder button should be displayed

-> m ()

Sets whether file chooser will offer to create new folders. This is only relevant if the action is not set to be FileChooserActionOpen.

setCurrentFolder

fileChooserSetCurrentFolder

Arguments

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

=> a

chooser: a FileChooser

-> b

file: the File for the new folder

-> m ()

(Can throw GError)

Sets the current folder for chooser from a File.

setCurrentName

fileChooserSetCurrentName

Arguments

:: (HasCallStack, MonadIO m, IsFileChooser a)

=> a

chooser: a FileChooser

-> Text

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 fileChooserSetFile instead.

Please see the documentation for those functions for an example of using fileChooserSetCurrentName as well.

setFile

fileChooserSetFile

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.

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

static void
prepare_file_chooser (GtkFileChooser *chooser,
                      GFile          *existing_file)
{
  gboolean document_is_new = (existing_file == NULL);

  if (document_is_new)
    {
      GFile *default_file_for_saving = g_file_new_for_path ("./out.txt");
      // the user just created a new document
      gtk_file_chooser_set_current_folder (chooser, default_file_for_saving, NULL);
      gtk_file_chooser_set_current_name (chooser, "Untitled document");
      g_object_unref (default_file_for_saving);
    }
  else
    {
      // the user edited an existing document
      gtk_file_chooser_set_file (chooser, existing_file, NULL);
    }
}

setFilter

fileChooserSetFilter

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.

setSelectMultiple

fileChooserSetSelectMultiple

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.
