To display a lot of text, use this subwindow as the child of a frame. It is capable of loading and saving files of ASCII text, and under Open Look and Motif, the text can be edited directly.
To allow the user to edit text under Windows as well as the other platforms, either invoke an external editor or create a multi-line text item on a panel.
Under Windows, there is an extended range of functions. Some take character positions - a single integer which can identify a character position - and others take line and character numbers. If you want to use a function that takes one form, but you only have the other, you can convert between them using a function such as text-window-xy-to-position or text-window-position-to-line. Note that line and character numbers start from zero.
The following callbacks are valid for the dialog box class:
To invoke default processing, call text-window-on-char.
