Member Function Documentation

int gui2::stacked_widget::current_layer ( ) const
inline

Gets the current visible layer number.

The current layer number will be -1 if all layers are currently visible. In this case, only the topmost (highest-numbered) layer will receive events.

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

Member Data Documentation

bool gui2::stacked_widget::find_in_all_layers_
private

If true, find will search all layers for widgets regardless of which one is visible.

Definition at line 157 of file stacked_widget.hpp.

Referenced by set_find_in_all_layers().

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.
