Currently it is possible to change font title for Page windows that is created by IG_GUI_page_window_create(). To set the font use IG_GUI_page_attribute_set() and to get the font, use IG_GUI_page_attribute_get() with the IG_GUI_PAGE_FONT_TITLE option. As in the case of thumbnail window, the user is responsible for creating and deleting the font. See the example below. |
