Document

Description

The Document class implements a special window for displaying and editing text. It is equivalent to an ordinary Window with a built-in multi-line edit control.

The text displayed in the window is represented by the text property, and the font used by the font property. Other text-edit properties include selection, seltext and canundo. Related methods are Cut, Clear, Paste and Undo.

You can optionally install an onChange callback to detect when the user edits the text.
