• ctxActiveId :: IORef WidgetId
   
• ctxClickedId :: IORef WidgetId
   
• ctxReleaseClickedId :: IORef WidgetId
   
• ctxPressPos :: IORef (Maybe V2)

  Where the held left and right buttons went down, cleared when they come up. A click belongs to the widget the press landed on, so a widget hit-tests this point as well as the release point. Nothing (a release with no press behind it) lets the release stand on its own.

• ctxRightPressPos :: IORef (Maybe V2)
   
• ctxFocusId :: IORef WidgetId
   
• ctxFocusVisible :: IORef Bool

  Focus last moved by keyboard, so the focused widget shows its ring. A pointer press hides it again.

Fields

• scrollWheelStep :: Float

  Pixels one wheel notch scrolls. The default is three text lines, which is what Windows and most desktops send a notch as.

• scrollSmoothTime :: Float

  Seconds a scroll takes to cover most of the distance to its target. 0 (the default) lands on it in the same frame.

Fields

• ssTuning :: !ScrollTuning

• ssCached :: !IntSet

  Scrollers whose geometry has been published this frame. Two scroll nodes can share a widget id (a table's frozen pane and its body), and without this the second would overwrite the first every frame, churning the store and flipping the geometry the commands read.
