bottom_bar_style

Appearance of the bottom bars.

If set to `ADW_TOOLBAR_FLAT`, bottom bars are flat and scrolling content has a subtle undershoot shadow when touching them, same as the [ `.undershoot-bottom`](style-classes.html#undershot-indicators) style class. This works well for simple content, e.g. [class@StatusPage] or [ class@PreferencesPage], where the background at the bottom of the page is uniform. Additionally, windows with sidebars should always use this style.

Undershoot shadow is only present if a bottom bar is actually present and visible. It is also never present if [ property@ToolbarView:extend-content-to-bottom-edge] is set to `TRUE`.

If set to `ADW_TOOLBAR_RAISED`, bottom bars have an opaque background and a persistent shadow, this is suitable for content such as utility panes, where some elements are directly adjacent to the bottom bars, or [class@TabView], where each page can have a different background.

`ADW_TOOLBAR_RAISED_BORDER` is similar to `ADW_TOOLBAR_RAISED`, but the shadow is replaced with a more subtle border. This can be useful for applications like image viewers.
