core.ui.mconfdialog

This module provides a menu-driven configuration dialog for the terminal UI system.

TIP

To use this module, you need to import it first: import("core.ui.mconfdialog")

NOTE

The UI module is primarily used for xmake's internal xmake f --menu menu-based visual configuration. It provides basic UI components that can also be used by users to implement their own terminal UIs.

The mconfdialog module extends boxdialog and provides a comprehensive menu-based configuration interface. It allows users to configure settings through a hierarchical menu, with support for boolean, number, string, choice, and menu configurations. It also includes features like help dialogs, search functionality, and scrollbar support for long menus.
