tui.overlay.add

tui.overlay.add DRAWFN

Registers a function that draws on top of the panes after every repaint.

Parameters

• DRAWFN: draws with absolute cursor moves (e.g. tui.overlay.box) and keeps no state of its own.

Notes

• Overlays survive page changes; remove page-specific ones yourself.
• Adding the same function twice is a no-op.
