Component | operator| (Component component, ElementDecorator decorator)
Component & | operator|= (Component &component, ComponentDecorator decorator)
Component & | operator|= (Component &component, ElementDecorator decorator)
Component | Vertical (Components children)
| A list of components, drawn one by one vertically and navigated vertically using up/down arrow key or 'j'/'k' keys.
Component | Vertical (Components children, int *selector)
| A list of components, drawn one by one vertically and navigated vertically using up/down arrow key or 'j'/'k' keys. This is useful for implementing a Menu for instance.
Component | Horizontal (Components children)
| A list of components, drawn one by one horizontally and navigated horizontally using left/right arrow key or 'h'/'l' keys.
Component | Horizontal (Components children, int *selector)
| A list of components, drawn one by one horizontally and navigated horizontally using left/right arrow key or 'h'/'l' keys.
Component | Tab (Components children, int *selector)
| A list of components, where only one is drawn and interacted with at a time. The |selector| gives the index of the selected component. This is useful to implement tabs.
Component | Stacked (Components children)
| A list of components to be stacked on top of each other. Events are propagated to the first component, then the second if not handled, etc. The components are drawn in the reverse order they are given. When a component take focus, it is put at the front, without changing the relative order of the other elements.
Component | Button (ButtonOption option)
| Draw a button. Execute a function when clicked.
Component | Button (ConstStringRef label, std::function< void()> on_click, ButtonOption option)
| Draw a button. Execute a function when clicked.
Component | Checkbox (CheckboxOption option)
| Draw checkable element.
Component | Checkbox (ConstStringRef label, bool *checked, CheckboxOption option)
| Draw checkable element.
Component | Input (InputOption option)
| An input box for editing text.
Component | Input (StringRef content, InputOption option)
| An input box for editing text.
Component | Input (StringRef content, StringRef placeholder, InputOption option)
| An input box for editing text.
Component | Menu (MenuOption option)
| A list of text. The focused element is selected.
Component | Menu (ConstStringListRef entries, int *selected, MenuOption option)
| A list of text. The focused element is selected.
Component | MenuEntry (MenuEntryOption option)
| A specific menu entry. They can be put into a Container::Vertical to form a menu.
Component | MenuEntry (ConstStringRef label, MenuEntryOption option)

Component | Radiobox (RadioboxOption option)
| A list of element, where only one can be selected.
Component | Radiobox (ConstStringListRef entries, int *selected, RadioboxOption option)
| A list of element, where only one can be selected.
Component | Dropdown (ConstStringListRef entries, int *selected)
| A dropdown menu.
Component | Dropdown (DropdownOption option)
| A dropdown menu.
Component | Toggle (ConstStringListRef entries, int *selected)
| An horizontal list of elements. The user can navigate through them.

Component | Slider (ConstStringRef label, Ref< float > value, ConstRef< float > min=0.f, ConstRef< float > max=100.f, ConstRef< float > increment=5.f)
Component | Slider (ConstStringRef label, Ref< long > value, ConstRef< long > min=0L, ConstRef< long > max=100L, ConstRef< long > increment=5L)
