Working with classes

Classes are commonly stored in class library files with an .ulb extension. Like all formula files, you can examine and organize class library files with the browser. Make sure all files are visible, or set the file type to Classes.

Usually though, you'll work with classes via class parameters.

Click the Browse button for a class parameter to select a different class. A modal browser window opens, which shows only those classes that are compatible with this class parameter.

Tip: In the browser window, click the Find Entries button and leave all fields blank to get a list of all compatible classes in the formula library.

Hold down the Browse button for a menu with other options:

		Click Copy to copy the currently selected class with all its sub-parameters to the Clipboard.
		Click Paste to copy the class information on the Clipboard to the class parameter. The class parameter must be compatible with the class parameter that you copied the class information from, otherwise an error message is shown.
		Click Reset Class to reset the class to the default class for the class parameter.
		Click Reset Parameters to reset the sub-parameters for the currently selected class to their default values. The class itself stays the same.
		Click Edit to open the class declaration in the formula editor.
