UML Diagrams

You can create UML diagrams by right-clicking on a class in any of the views and selecting Show Diagram or from the editor, right-click on a class name and select Show > Diagram.

You can select the relevant classes for which to draw the diagram from the select Select Types button (see UML Diagrams Select Types).

For the selected classes, the diagram can display inheritance, associations (pointers) and class members prefs (see UML Diagrams Preferences).

Note

To see the inherited pointers of a class, you need to select its parents and show at least one level of associations.

For the description of diagram drawing conventions go to UML Diagrams Legend.

In the diagram editor you can right-click on classes and select Go To Source to jump to the source code.

You can jump to the declaration of a field, event, or method via right-click Go To Source.

To show or hide members of a class use right-click Members.

UML Diagrams - Select Types

A diagram is created around a set of relevant classes you specify. For example when you decide to show parents, children or associations by using UML Diagrams Preferences, it applies only to selected classes. In a diagram the selected classes are colored with yellow fill (see also the UML Diagrams Legend).

The right list shows the selected classes. Use left/right arrows or double click to select the relevant classes.

You can also add/remove an element to/from the current selection by right clicking on it in the diagram and choosing “Select Type”/”Deselect Type”:

Show full method signature
Show labels on association edges
Route edges orthogonally

UML Diagrams - Legend

	A class.
	A selected class.
	A selected class with members. The cells are (in order) for fields, events, and methods (functions and tasks). Each member name is preceded by an access modifier flag: `+ (plus)` for public, `- (minus)` for private, and `# (hash)` for protected.
	A predefined class.
	Inheritance: ChildClass inherits from ParentClass.
	Inheritance with parameters: SetParams inherits from AClassWithParams#(int) (sets T to int).
	Implementation: AClass implements InterfaceClass.
	Association: AClass points to BClass (has a field f_bcl of type BClass).
