Widgets

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

TODO inline pictures of some of these

Autocomplete - select predefined value by combining text entry with menus
Button - clickable buttons with keybindings and tooltips
Toggle - checkboxes, switches, and other toggles
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
table::Table - rows and columns, supporting filtering and pagination
TextBox - 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.

Like std::include_bytes!, but also returns its argument, the relative path to the bytes

Autocomplete
ButtonBuilder
ButtonStyle
Cached	Store a cached key/value pair, only recalculating when the key changes.
Canvas
Choice
Color
CompareTimes
DrawWithTooltips
Drawable	Geometry that’s been uploaded to the GPU once and can be quickly redrawn many times. Create by creating a `GeomBatch` and calling `ctx.upload(batch)`.
EdgeInsets
EventCtx
FanChart
Filler	Doesn’t do anything by itself, just used for widgetsing. Something else reaches in, asks for the ScreenRectangle to use.
GeomBatch	A mutable builder for a group of colored polygons.
GeomBatchStack	Similar to [`Widget::row`]/[`Widget::column`], but for `GeomBatch`s instead of [`Widget`]s, and follows a builder pattern
GfxCtx
Image	A stylable UI component builder which presents vector graphics from an `ImageSource`.
LinePlot
LinearGradient
Menu
MultiButton
Panel
PersistentSplit
PlotOptions
Prerender
ScatterPlot
ScreenDims	ScreenDims is in units of logical pixels, as opposed to physical pixels.
ScreenPt	ScreenPt is in units of logical pixels, as opposed to physical pixels.
ScreenRectangle	ScreenRectangle is in units of logical pixels, as opposed to physical pixels.
Series
Settings	Customize how widgetry works. These settings can’t be changed after starting.
Slider
Spinner
Stash	An invisible widget that stores some arbitrary data on the Panel. Users of the panel can read and write the value. This is one method for “returning” data when a State completes.

TabController
Text
TextBox
TextSpan

WidgetOutput

Axis
ContentMode	Rules for how content should stretch to fill its bounds
ControlState
CornerRounding
DrawBaselayer	Before `State::draw` is called, draw something else.
Event
Fill
Font
HorizontalAlignment
ImageSource	The visual
Key
MultiKey
Outcome	The result of a Panel handling an event
RewriteColor	A way to transform all colors in a GeomBatch.
Transition	When a state responds to an event, it can specify some way to manipulate the stack of states.
UpdateType
VerticalAlignment

SharedAppState	Any data that should last the entire lifetime of the application should be stored in the struct implementing this trait.
SimpleState	Many states fit a pattern of managing a single panel, handling mouseover events, and other interactions on the map. Implementing this instead of `State` reduces some boilerplate.
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.
