BuilderPlus is an extension to HTBasic that adds code syntax for creating and programming dialog and widget controls for making GUIs (graphical user interfaces) for virtual instruments, device control, and graphical data presentation screens.
ScreenBuilder is the companion visual UI design tool. So you can design GUis both visually and in code either separately or in combination. This is like other IDEs that provide both a code window and visual design window and you can choose one or the other as your main design tool or switch between them. It is often easier to design visually, but some tasks can be more efficient in code where you can use editing features like copy/paste and search/replace to more rapidly implement repetitive or similar design features.
ScreenBuilder/Custom Configurations
You can also perform custom configurations on some BuilderPlus features.
See ScreenBuilder for information on the ScreenBuilder application.
