Release 10.1A: OpenEdge Development:
AppBuilder

> ## Simulating character applications

> To help you develop applications for character interfaces, the AppBuilder simulates character environments in its design windows. Within a character simulator window, the widgets appear as they would in a character environment, to the extent possible. For example, buttons appear as they do in character environments, but some other widgets, such as radio sets, have a graphical appearance. To see exactly how the widgets appear at run time, you must run the application in the character environment.

> Note: You can run character applications directly from the AppBuilder. For instructions, see the "Running character applications" section.

> There are some operations that you can perform on widgets in a graphical window that you cannot perform on widgets in the character simulator window. Make sure to consider the following when designing a character interface:

> - You can size buttons horizontally but not vertically. The height of a button in a character layout is one character.

> - A browser must be at least six characters high.

> - A (horizontal) radio set must be at least three characters high.

> When you create a new design window or dialog box, the New dialog box appears. Select TTY Window or TTY Dialog to put the master layout in character mode. In general, if you plan to have both character and graphical layouts, make the master layout graphical.
