| 40 | * @Short_description: A stacking container | |||
| 41 | * @Title: CtkStack | |||
| 42 | * @See_also: #CtkNotebook, #CtkStackSwitcher | |||
| 43 | * | |||
| 44 | * The CtkStack widget is a container which only shows | |||
| 45 | * one of its children at a time. In contrast to CtkNotebook, | |||
| 46 | * CtkStack does not provide a means for users to change the | |||
| 47 | * visible child. Instead, the #CtkStackSwitcher widget can be | |||
| 48 | * used with CtkStack to provide this functionality. | |||
| 49 | * | |||
| 50 | * Transitions between pages can be animated as slides or | |||
| 51 | * fades. This can be controlled with ctk_stack_set_transition_type(). | |||
| 52 | * These animations respect the #CtkSettings:ctk-enable-animations | |||
| 53 | * setting. | |||
| 54 | * | |||
| 55 | * The CtkStack widget was added in CTK+ 3.10. | |||
| 56 | * | |||
| 57 | * # CSS nodes | |||
| 58 | * | |||
| 59 | * CtkStack has a single CSS node named stack. | |||
