Renderers

​

All visual components of an EntireJ application are displayed using Renderers. Renderers come in many shapes and forms and for different parts of an application. The Application Renderers page within the application.ejprop editor is the place to add or change the renderers for an application

​

Renderers are the GUI elements that users interacts with. Every graphical element of an application is made available to the application through a given renderer. The Renderers themselves do not belong to the EntireJ core and can be different across the different type of Client Frameworks. If an application requires data to be displayed differently then a renderer can be creaed and assigned to the application by adding it in the application.ejprop file giving it a name. The name is what is added to each form where the renderer is to be used. This means that renderers can completely changed without having to make modifications to the place where it is being used
