Dock | The `PanelDock` is a widget designed to contain widgets that can be docked. Use the `PanelDock` as the top widget of your dockable UI.
DocumentWorkspace |
Frame | The `PanelFrame` is a widget containing panels to display in an area. The widgets are added internally in an `AdwTabView` to display them one at a time like in a stack.
FrameHeaderBar | A header bar for `PanelFrame`. It can optionally show an icon, it can have a popover to be displace, and it can also have prefix and suffix widgets.
FrameSwitcher | A `PanelFrameSwitcher` is a `PanelFrameHeader` that shows a row of buttons to switch between `GtkStack` pages, not disimilar to a `GtkStackSwitcher`.
FrameTabBar | A `PanelFrameHeader` that implements switching between tab views in a `PanelFrame`.
Grid | The `PanelGrid` is a widget used to layout the dock item in the center area.

MenuManager | The goal of `PanelMenuManager` is to simplify the process of merging multiple GtkBuilder .ui files containing menus into a single representation of the application menus. Additionally, it provides the ability to “unmerge” previously merged menus.
OmniBar | A multi-use widget for user interaction in the window header bar. You can add widgets, a popover to provide action items, an icon, updates on progress and pulse the main widget.
Paned | A `PanelPaned` is the concrete widget for a panel area.
Position | Specifies a position in the dock. You receive a `PanelPosition` in the handler to `PanelDock::create-frame`.
