Jprogressbar not updating
The preceding diagram illustrates this subtle (and often confusing) point: So Swing does have a strong MVC lineage.But it's also important to reiterate that our MVC architecture serves two distinct purposes: Although these two concepts are linked by the MVC design, they may be treated somewhat orthogonally from the developer's perspective.
That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working code examples. To support this paradigm, Swing defines a separate model interface for each component that has a logical abstraction.This separation provides programs with the option of plugging in their own model implementations for Swing components.Of course with some components, the model categorization falls somewhere in between GUI state models and application-data models, depending on the context in which the model is used. These models are highlighted in purple in the preceding table.
Swing's separable model API makes no specific distinctions between GUI state models and application-data models; ho wever, we have clarified this difference here to give developers a better understanding of when and why they might wish to program with the separable models.In general, application developers only need to understand the capabilities of this mechanism in order to decide provides the API for applications to manage the look-and-feel at this level.If you're one of those developers who needs (or wants) to develop a custom look-and-feel, it's critical to understand these underpinnings before you write a single line of code.One noteworthy point is that as an application developer, you should think of a component's view/controller responsibilities as being handled by the generic component class (such as. The component class then delegates the look-and-feel-specific aspects of those responsibilities to the UI object that is provided by the currently installed look-and-feel.
