Widgets

Widgets are the building blocks of every Niblet frame. Load them from render.star:

load("render.star", "render")

Widget	Use
`Root`	Set the frame boundary and timing
`Box`	Set size, background, and child alignment
`Row`	Arrange children horizontally
`Column`	Arrange children vertically
`Stack`	Layer children on the same canvas
`Padding`	Add space around a child
`Text`	Draw one line with a bundled font
`WrappedText`	Wrap text within a fixed width
`Image`	Decode and draw supported image data
`Circle`	Draw a filled circle
`Plot`	Draw a compact data series
`PieChart`	Draw weighted circular segments
`Marquee`	Scroll content that does not fit
`Animation`	Show children as sequential frames
`Sequence`	Combine timed child sequences

Many widgets expose size(), while animated widgets can expose frame_count(). Colors accept #rgb, #rrggbb, #rgba, and #rrggbbaa.

This page lists the core widgets rather than every attribute. Run niblet apps validate . to catch widget names or attributes unsupported by your installed runtime.
