◆ current_layer()

int gui2::stacked_widget::current_layer ( ) const

Gets the current visible layer number.

If more than one but not all layers are visible, this will be the number of the last one made visible.

Returns: The most recently shown layer

◆ generator_

generator_base* gui2::stacked_widget::generator_

private

Contains a pointer to the generator.

The pointer is not owned by this class, it's stored in the content_grid_ of the scrollbar_container super class and freed when its grid is freed.

NOTE: the generator is initialized with has_minimum (first arg) as false, which seems a little counter-intuitive at first. After all, shouldn't the stack always have at least one layer visible? However, this allows select_layer to function correctly.

If has_minimum is true, the generator policy selected (one_item) can leave multiple layers selected when selecting a new one. This is most likely due to cases where the new chosen layer comes after the currently selected one. In that case, the generator would not allow the interim state where no layer before the new chosen layer is reached in the loop.
