core.ui.inputdialog

This module provides an input dialog for text input in the terminal UI system.

TIP

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

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 inputdialog module extends textdialog and provides a text input field for user input. It includes a prompt label and a text edit component.
