Description :
The ParameterViews module groups together all graphical components dedicated to displaying and editing parameters in the OSCAR/FORGE interface. It ensures the link between DSP parameters, user encoders and their on-screen visual representation, while offering several types of views adapted to numerical and discrete parameters.
📋 General Description
The ParameterViews module constitutes the presentation layer of parameters within the OSCAR/FORGE framework’s graphical interface. Its role is to ensure the link between DSP parameter objects and their on-screen visual representation.
Each view instance is associated with a user parameter and with one of the three parameter zones displayed on the interface.
It is responsible for:
- displaying the parameter name and value;
- graphically representing its state;
- managing interactions with the associated encoder;
- detecting changes coming from the user or other sources (MIDI, preset loading, etc.);
- dynamically updating the display when the value changes.
The system thus allows complete separation of the business logic of parameters from their graphical representation.
Architecture The module is based on an object-oriented architecture based on inheritance.
Each parameter type has its own specialized display class, while sharing a common base provided by the cParameterView base class.
