## Description

The GtkFileChooserButton is a widget that lets the user select a file. It implements the GtkFileChooser interface. Visually, it is a file name with a button to bring up a GtkFileChooserDialog. The user can then use that dialog to change the file associated with that button. This widget does not support setting the "select-multiple" property to `TRUE`.

Example 40. Create a button to let the user select a file in /etc

    {
      GtkWidget *button;
      button = gtk_file_chooser_button_new (_("Select a file"),
                                            GTK_FILE_CHOOSER_ACTION_OPEN);
      gtk_file_chooser_set_current_folder (GTK_FILE_CHOOSER (button),
                                           "/etc");
    }

The GtkFileChooserButton supports the GtkFileChooserActions `GTK_FILE_CHOOSER_ACTION_OPEN` and `GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER`.

### Important

The GtkFileChooserButton will ellipsize the label, and thus will thus request little horizontal space. To give the button more space, you should call `gtk_widget_size_request()`, `gtk_file_chooser_button_set_width_chars()`, or pack the button in such a way that other interface elements give space to the widget.

### GtkFileChooserButton

    typedef struct _GtkFileChooserButton GtkFileChooserButton;

This should not be accessed directly. Use the accessor functions below.

### gtk_file_chooser_button_new ()

    GtkWidget *         gtk_file_chooser_button_new         (const gchar *title,
                                                             GtkFileChooserAction action);

Creates a new file-selecting button widget.

`title` : | the title of the browse dialog.
`action` : | the open mode for the widget.
Returns : | a new button widget.

Since 2.6

### gtk_file_chooser_button_new_with_backend ()

    GtkWidget *         gtk_file_chooser_button_new_with_backend
                                                            (const gchar *title,

### Warning

`gtk_file_chooser_button_new_with_backend` has been deprecated since version 2.14 and should not be used in newly-written code. Use `gtk_file_chooser_button_new()` instead.

Creates a new file-selecting button widget using `backend`.

`title` : | the title of the browse dialog.
`action` : | the open mode for the widget.
`backend` : | the name of the GtkFileSystem backend to use.

Creates a GtkFileChooserButton widget which uses `dialog` as its file-picking window.

Note that `dialog` must be a GtkDialog (or subclass) which implements the GtkFileChooser interface and must not have `GTK_DIALOG_DESTROY_WITH_PARENT` set.

Also note that the dialog needs to have its confirmative button added with response `GTK_RESPONSE_ACCEPT` or `GTK_RESPONSE_OK` in order for the button to take over the file selected in the dialog.

`dialog` : | the widget to use as dialog
Returns : | a new button widget.

Since 2.6

### gtk_file_chooser_button_get_title ()

    const gchar *       gtk_file_chooser_button_get_title   (GtkFileChooserButton *button);

Retrieves the title of the browse dialog used by `button`. The returned value should not be modified or freed.

`button` : | the button widget to examine.
Returns : | a pointer to the browse dialog's title.

Since 2.6

### gtk_file_chooser_button_set_title ()

    void                gtk_file_chooser_button_set_title   (GtkFileChooserButton *button,
                                                             const gchar *title);

Modifies the `title` of the browse dialog used by `button`.

`button` : | the button widget to modify.
`title` : | the new browse dialog title.

Since 2.6

### gtk_file_chooser_button_get_width_chars ()

    gint                gtk_file_chooser_button_get_width_chars
                                                            (GtkFileChooserButton *button);

Retrieves the width in characters of the `button` widget's entry and/or label.

`button` : | the button widget to examine.
Returns : | an integer width (in characters) that the button will use to size itself.

Since 2.6

### gtk_file_chooser_button_set_width_chars ()

    void                gtk_file_chooser_button_set_width_chars
                                                            (GtkFileChooserButton *button,
                                                             gint n_chars);

Sets the width (in characters) that `button` will use to `n_chars`.

`button` : | the button widget to examine.
`n_chars` : | the new width, in characters.

Since 2.6

### gtk_file_chooser_button_get_focus_on_click ()

Returns whether the button grabs focus when it is clicked with the mouse. See `gtk_file_chooser_button_set_focus_on_click()`.

`button` : | a GtkFileChooserButton
Returns : | `TRUE` if the button grabs focus when it is clicked with the mouse.

Since 2.10

### gtk_file_chooser_button_set_focus_on_click ()
