Documentation

Overview

Package tkbind holds the MVVM binding adapters that are specific to the pixel toolkit (github.com/go-widgets/toolkit) — the widgets whose value/callback shape the generic mvvm adapters can't express, such as a two-handle range slider (a multi-argument OnChange). It is the ONLY MVVM package that imports toolkit; the core mvvm package stays backend-free.

Functions

func BindRange

func BindRange(low, high *mvvm.Observable[float64], rs *toolkit.RangeSlider, invalidate func()) (unbind func())

BindRange two-way-binds a RangeSlider's Low/High to a pair of observables. The slider fires OnChange(low, high) on every drag — a shape the generic single-value BindField can't take — so this adapter fans it out to both observables and pushes each back to the matching field. Loop-free: the field writes are silent and Observable.Set skips equal values. Returns an unbind that restores the prior OnChange and detaches both subscriptions.
