| 39 | * @Short_description: Groups of global keyboard accelerators for an | |||
| 40 | * entire CtkWindow | |||
| 41 | * @Title: Accelerator Groups | |||
| 42 | * @See_also: ctk_window_add_accel_group(), ctk_accel_map_change_entry(), | |||
| 43 | * ctk_label_new_with_mnemonic() | |||
| 44 | * | |||
| 45 | * A #CtkAccelGroup represents a group of keyboard accelerators, | |||
| 46 | * typically attached to a toplevel #CtkWindow (with | |||
| 47 | * ctk_window_add_accel_group()). Usually you won’t need to create a | |||
| 48 | * #CtkAccelGroup directly; instead, when using #CtkUIManager, CTK+ | |||
| 49 | * automatically sets up the accelerators for your menus in the ui | |||
| 50 | * manager’s #CtkAccelGroup. | |||
| 51 | * | |||
| 52 | * Note that “accelerators” are different from | |||
| 53 | * “mnemonics”. Accelerators are shortcuts for | |||
| 54 | * activating a menu item; they appear alongside the menu item they’re a | |||
| 55 | * shortcut for. For example “Ctrl+Q” might appear alongside the “Quit” | |||
| 56 | * menu item. Mnemonics are shortcuts for GUI elements such as text | |||
| 57 | * entries or buttons; they appear as underlined characters. See | |||
| 58 | * ctk_label_new_with_mnemonic(). Menu items can have both accelerators | |||
| 59 | * and mnemonics, of course. | |||
