[−][src]Crate widgetry

Widgets

If none of these do what you need, implementing a new [WidgetImpl] isn't tough.

TODO inline pictures of some of these

[AreaSlider] - slider with an associated area graph
[Autocomplete] - select predefined value by combining text entry with menus
[Button] - clickable buttons with keybindings and tooltips
[Checkbox] - toggle between two buttons
[CompareTimes] - a scatter plot specialized for comparing times
[DrawWithTooltips] - draw static geometry, with mouse tooltips in certain regions
[Dropdown] - a button that expands into a menu
[FanChart] - visualize a range of values over time
[Filler] - just carve out space in the layout for something else
[JustDraw] (argh private) - just draw text, GeomBatches, SVGs
[LinePlot] - visualize 2 variables with a line plot
[Menu] - select something from a menu, with keybindings
[MultiButton] - clickable regions in one batch of geometry
[PersistentSplit] - a button with a dropdown to change its state
[ScatterPlot] - visualize 2 variables with a scatter plot
[Slider] - horizontal and vertical sliders
[Spinner] - numeric input with up/down buttons
[TexBox] - single line text entry

app_state	A widgetry application splits its state into two pieces: global shared state that lasts for the entire lifetime of the application, and a stack of smaller states, only one of which is active at a time. For example, imagine an application to view a map. The shared state would include the map and pre-rendered geometry for it. The individual states might start with a splash screen or menu to choose a map, then a map viewer, then maybe a state to drill down into pieces of the map.

Transition	When a state responds to an event, it can specify some way to manipulate the stack of states.

SharedAppState	Any data that should last the entire lifetime of the application should be stored in the struct implementing this trait.
State	A temporary state of an application. There's a stack of these, with the most recent being the active one.
TextExt
WidgetImpl	Create a new widget by implementing this trait. You can instantiate your widget by calling `Widget::new(Box::new(instance of your new widget))`, which gives you the usual style options.
