Module Wrappers.File_chooser

type t = [ `file_chooser ] Gobject.obj
val from_gobject : 'a Gobject.obj -> t
val set_select_multiple : t -> bool -> unit

Sets whether multiple files can be selected in the file chooser.

This is only relevant if the action is set to be %GTK_FILE_CHOOSER_ACTION_OPEN or %GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER.

val set_filter : t -> [ `file_filter | `filter | `object_ ] Gobject.obj -> unit

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.

val set_file : t -> Ocgtk_gio.Gio.Wrappers.File.t -> (bool, GError.t) result

Sets @file as the current filename for the file chooser.

This includes changing to the file’s parent folder and actually selecting the file in list. If the @chooser is in %GTK_FILE_CHOOSER_ACTION_SAVE 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 @file.

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 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);

}

```

val set_current_name : t -> string -> unit

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 method@Gtk.FileChooser.set_file instead.

Please see the documentation for those functions for an example of using method@Gtk.FileChooser.set_current_name as well.

val set_current_folder : t -> Ocgtk_gio.Gio.Wrappers.File.t option -> (bool, GError.t) result

Sets the current folder for @chooser from a `GFile`.

val set_create_folders : t -> bool -> unit

Sets whether file chooser will offer to create new folders.

This is only relevant if the action is not set to be %GTK_FILE_CHOOSER_ACTION_OPEN.

val set_choice : t -> string -> string -> unit

Selects an option in a 'choice' that has been added with gtk_file_chooser_add_choice().

For a boolean choice, the possible options are "true" and "false".

val set_action : t -> Gtk_enums.filechooseraction -> unit

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 %GTK_FILE_CHOOSER_ACTION_SAVE but not if the action is %GTK_FILE_CHOOSER_ACTION_OPEN.

val remove_shortcut_folder : t -> Ocgtk_gio.Gio.Wrappers.File.t -> (bool, GError.t) result

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

val remove_filter : t -> [ `file_filter | `filter | `object_ ] Gobject.obj -> unit

Removes @filter from the list of filters that the user can select between.

val remove_choice : t -> string -> unit

Removes a 'choice' that has been added with gtk_file_chooser_add_choice().

val get_shortcut_folders : t -> Ocgtk_gio.Gio.Wrappers.List_model.t

Queries the list of shortcut folders in the file chooser.

You should not modify the returned list model. Future changes to @chooser may or may not affect the returned model.

val get_select_multiple : t -> bool

Gets whether multiple files can be selected in the file chooser.

Gets the current set of user-selectable filters, as a list model.

See method@Gtk.FileChooser.add_filter and method@Gtk.FileChooser.remove_filter for changing individual filters.

You should not modify the returned list model. Future changes to @chooser may or may not affect the returned model.

val get_filter : t -> [ `file_filter | `filter | `object_ ] Gobject.obj option

Gets the current filter.

Lists all the selected files and subfolders in the current folder of @chooser as `GFile`.

val get_file : t -> Ocgtk_gio.Gio.Wrappers.File.t option

Gets the `GFile` for the currently selected file in the file selector.

If multiple files are selected, one of the files will be returned at random.

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

val get_current_name : t -> string option

Gets the current name in the file selector, as entered by the user.

This is meant to be used in save dialogs, to get the currently typed filename when the file itself does not exist yet.

val get_current_folder : t -> Ocgtk_gio.Gio.Wrappers.File.t option

Gets the current folder of @chooser as `GFile`.

val get_create_folders : t -> bool

Gets whether file chooser will offer to create new folders.

val get_choice : t -> string -> string option

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

val get_action : t -> Gtk_enums.filechooseraction

Gets the type of operation that the file chooser is performing.

val add_shortcut_folder : t -> Ocgtk_gio.Gio.Wrappers.File.t -> (bool, GError.t) result

Adds a folder to be displayed with the shortcut folders in a file chooser.

val add_filter : t -> [ `file_filter | `filter | `object_ ] Gobject.obj -> unit

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.

val add_choice : t -> string -> string -> string array option -> string array option -> unit

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 method@Gtk.FileChooser.set_choice before the dialog is shown, and you can obtain the user-selected value in the signal@Gtk.Dialog::response signal handler using method@Gtk.FileChooser.get_choice.
