Manual

Class diagrams

The following image shows the summarized class diagram of the manual editor of To match sound-image exercises that is part of Tareas.

In the diagram above we can see that the information of the exercise that is being edited will be stored in the "CurrentEmparejarExercise" class, that has all static fields. This class also stores the information of all image-sound pairs that the exercise has and each of them is represented by an instance of the "PairInfo" class.

The main panel is an object of class "EmparejarMainPanel" which contains three subpanels: "Image-sound pairs", "Images" and "Sounds".

The image-sound pairs panel ("leftPanel") is a "PreviewPanel" object and contains a toolbar and the panel that contains all exercise pairs ("PairsPanel"). The exercise configuration panel is an "ExerciseConfigPanel" object and it is instantiated each time the user clicks on the corresponding button located in the image-sound pairs panel toolbar.

An object of type "MultimediaResourcesFilterPanel" ("rightPanel") creates two instances of the class "MultimediaFilterPanel". Each of these instances represents a panel that filters all the available multimedia resources by type (images, sounds, videos...) and in this case are "Images" and "Sounds" panels.
