            GLADE_FILE_DIALOG_ACTION_SAVE
    } GladeUtilFileDialogType;

### enum GladeUIMessageType

    typedef enum
    {
    	GLADE_UI_INFO,
    	GLADE_UI_WARN,
    	GLADE_UI_ERROR,
    	GLADE_UI_ARE_YOU_SURE,
    	GLADE_UI_YES_OR_NO
    } GladeUIMessageType;

### glade_util_get_type_from_name ()

    GType               glade_util_get_type_from_name       (const gchar *name,
                                                             gboolean have_func);

Returns the type using the "get type" function name based on `name`. If the `have_func` flag is true,`name` is used directly, otherwise the get-type function is contrived from `name` then used.

`name` : | the name of the GType - like 'GtkWidget' or a "get-type" function.
`have_func` : | function-name flag -- true if the name is a "get-type" function.
Returns : | the new GType

### glade_utils_get_pspec_from_funcname ()

    GParamSpec *        glade_utils_get_pspec_from_funcname (const gchar *funcname);

`funcname` : | the symbol name of a function to generate a GParamSpec
Returns : | A GParamSpec created by the delagate function specified by `funcname`

### glade_util_ui_message ()

    gboolean            glade_util_ui_message               (GtkWidget *parent,

                                                             ...);

Creates a new warning dialog window as a child of `parent` containing the text of `format`, runs it, then destroys it on close. Depending on `type`, a cancel button may apear or the icon may change.

`parent` : | a GtkWindow cast as a GtkWidget
`type` : | a GladeUIMessageType
`widget` : | a GtkWidget to append to the dialog vbox
`format` : | a printf style format string
`...` : | args for the format.
Returns : | True if the `type` was GLADE_UI_ARE_YOU_SURE and the user selected "OK", True if the `type` was GLADE_UI_YES_OR_NO and the user selected "YES"; False otherwise.

This is a GCompareFunc that compares the labels of two stock items, ignoring any '_' characters. It isn't particularly efficient.

`a` : | a gconstpointer to a GtkStockItem
`b` : | a gconstpointer to a GtkStockItem
Returns : | negative value if `a` < `b`; zero if `a` = `b`; positive value if `a` > `b`

### glade_util_hide_window ()

    void                glade_util_hide_window              (GtkWindow *window);

`title` : | dialog title
`project` : | a GladeProject used when saving
`parent` : | a parent GtkWindow for the dialog
`action` : | a GladeUtilFileDialogType to say if the dialog will open or save
Returns : | a "glade file" file chooser dialog. The caller is responsible for showing the dialog

### glade_util_replace ()

    void                glade_util_replace                  (gchar *str,
                                                             gchar a,

`b` : | a gchar

### glade_util_read_prop_name ()

    gchar *             glade_util_read_prop_name           (const gchar *str);

Return a usable version of a property identifier as found in a freshly parserd GladeInterface

`str` : | a string

### glade_util_duplicate_underscores ()

    gchar *             glade_util_duplicate_underscores    (const gchar *name);

Duplicates `name`, but the copy has two underscores in place of any single underscore in the original.

`name` : | a string
Returns : | a newly allocated string

### glade_util_add_selection ()

    void                glade_util_add_selection            (GtkWidget *widget);

### glade_util_remove_selection ()

    void                glade_util_remove_selection         (GtkWidget *widget);

Remove visual selection from this GtkWidget

`widget` : | a GtkWidget

Returns : | `TRUE` if `widget` has visual selection, `FALSE` otherwise

### glade_util_clear_selection ()

    void                glade_util_clear_selection          (void);

Use this to itterate over all children in a GtkContainer, as it used `_forall()` instead of `_foreach()` (and the GTK+ version of this function is simply not exposed).

Note that `glade_widget_class_get_children()` is the high-level abstraction and will usually end up calling this function.

`container` : | a GtkContainer
Returns : | a GList giving the contents of `container`

### glade_util_count_placeholders ()

    gint                glade_util_count_placeholders       (GladeWidget *parent);

                                                             gint column);

### glade_util_canonical_path ()

    gchar *             glade_util_canonical_path           (const gchar *path);

`path` : | any path that may contain ".." or "." components
Returns : | an absolute path to the specified file or directory that contains no ".." or "." components (this does not call readlink like `realpath()` does). Note: on some systems; I think its possible that we dont have permission to execute in the directory in which the glade file resides; I decided finally to do it this way anyway since libc's `realpath()` does exactly the same.

### glade_util_copy_file ()

    gboolean            glade_util_copy_file                (const gchar *src_path,

Copies a file from `src` to `dest`, queries the user if it involves overwriting the target and displays an error message upon failure.

`src_path` : | the path to the source file
`dest_path` : | the path to the destination file to create or overwrite.
Returns : | True if the copy was successfull.

### glade_util_class_implements_interface ()

    gboolean            glade_util_class_implements_interface
                                                            (GType class_type,
                                                             GType iface_type);

`class_type` : | A GType
`iface_type` : | A GType
Returns : | whether `class_type` implements the `iface_type` interface

### glade_util_load_library ()

    GModule *           glade_util_load_library             (const gchar *library_name);

Loads the named library from the Glade modules directory, or failing that from the standard platform specific directories.
