Within this method the component can react to the alternation and e.g. a new label text is assigned to it), the onset method is executed automatically. The practical thing about the property, however, is the possibility to associate with it the onset and onget methods.Įvery time, the property is modified (e.g. Superficially considered, the property acts just like a variable, it stores a value (e.g. Thus recalling the above mentioned push button component with a label, the property is ideal to configure the label text. With a property the component is able to store a parameter. Knowing this you will be able to decide by yourself which technique is the most suitable for your particular application case. The sections below introduce the respective project members intended to implement the interface. Since GUI components are ordinary classes, the interface is implemented from adequate project members by simply adding them to the component. This can be achieved through the component interface. Unless you implement individual push button components for all the possible label variants, you will need a way to configure every button with its individual label. one button Cancel and another one Continue. The label should inform the user about the function of the respective button within the application, e.g. Let's imagine a simple push button component displaying a text label. Through the interface the component can be configured, instructed to perform an operation, its current state can be queried or one component can communicate with other components. Without the interface the component would act like a kind of GUI black box. In simple terms, the interface permits to exchange data with the component. Now we will focus on the component interface.
