## Details

### gimp_radio_group_new ()

    GtkWidget *         gimp_radio_group_new                (gboolean in_frame,
                                                             const gchar *frame_title,
                                                             ...);

Convenience function to create a group of radio buttons embedded into a GtkFrame or GtkVbox.

`in_frame` : | `TRUE` if you want a GtkFrame around the radio button group.
`frame_title` : | The title of the Frame or `NULL` if you don't want a title.
`...` : | A `NULL`-terminated `va_list` describing the radio buttons.
Returns : | A GtkFrame or GtkVbox (depending on `in_frame`).

                                                             const gchar *text);

### Warning

`gimp_pixmap_button_new` is deprecated and should not be used in newly-written code.

Convenience function that creates a GtkButton with a GimpPixmap and an optional GtkLabel.

### gimp_toggle_button_sensitive_update ()

    void                gimp_toggle_button_sensitive_update (GtkToggleButton *toggle_button);

If you attached a pointer to a GtkWidget with `g_object_set_data()` and the "set_sensitive" key to the GtkToggleButton, the sensitive state of the attached widget will be set according to the toggle button's "active" state.

You can attach an arbitrary list of widgets by attaching another "set_sensitive" data pointer to the first widget (and so on...).

This function can also set the sensitive state according to the toggle button's inverse "active" state by attaching widgets with the "inverse_sensitive" key.

`toggle_button` : | The GtkToggleButton the "set_sensitive" and "inverse_sensitive" lists are attached to.

### gimp_toggle_button_update ()

                                                             gpointer data);

Note that this function calls `gimp_toggle_button_sensitive_update()`.

`widget` : | A GtkRadioButton.
`data` : | A pointer to a gint variable which will store the value of GPOINTER_TO_INT (g_object_get_data (`widget`, "gimp-item-data")).

This callback can set the number of decimal digits of an arbitrary number of GtkSpinButton's. To use this functionality, attach the spinbuttons as list of data pointers attached with `g_object_set_data()` with the "set_digits" key.

See `gimp_toggle_button_sensitive_update()` for a description of how to set up the list.

`widget` : | A GimpUnitMenu.

Note that the `label_text` can be `NULL` and that the widget will be attached starting at (`column` + 1) in this case, too.

`table` : | The GtkTable the widgets will be attached to.
`column` : | The column to start with.
`row` : | The row to attach the widgets.
`label_text` : | The text for the GtkLabel which will be attached left of the widget.

### gimp_label_set_attributes ()

    void                gimp_label_set_attributes           (GtkLabel *label,
                                                             ...);

Sets Pango attributes on a GtkLabel in a more convenient way than `gtk_label_set_attributes()`.

This function is useful if you want to change the font attributes of a GtkLabel. This is an alternative to using PangoMarkup which is slow to parse and akward to handle in an i18n-friendly way.

The attributes are set on the complete label, from start to end. If you need to set attributes on part of the label, you will have to use the PangoAttributes API directly.

`label` : | a GtkLabel
`...` : | a list of PangoAttrType and value pairs terminated by -1.
