class TUI::Picker(W)

• TUI::Picker(W)
• Reference
• Object

Overview

Wraps any Pickable widget as a modal value-picker. Does not modify the wrapped widget — filters its key input externally: Enter reports the selection, Esc cancels, listed chars are swallowed (e.g. to suppress mutating actions like delete/new while picking), everything else passes through to the wrapped widget unchanged.

Defined in:
