pub fn init(cx: &mut App)Expand description
Bind tab and shift-tab. Call once at startup.
Optional, like crate::input::init — the actions are public, so an app
that wants different keys binds those instead. The bindings are global
rather than scoped to a context: traversal is a property of the window, not
of whatever happens to be focused.
Nothing in this crate claims tab for itself, deliberately. A multi-line
field could reasonably insert one, but trapping tab inside a text box is
the classic way to make a form impossible to leave by keyboard.
Decrement/Increment on left/right are for a control that holds a
value rather than a press — slider
is the one. They
carry no step: only the caller knows the range, and a library that picked
one would be picking it for a percentage and a font size alike.
