A page is the basic building block of an application. When you build an application in Application Builder, you create pages that contain user interface elements, such as tabs, lists, buttons, items, and regions.
You add controls to a page on the Page Definition.
To view the Page Definition of an existing page:
Navigate to the Workspace home page.
Click the Application Builder icon.
Select an application.
Select a page.
The Page Definition appears and is divided into three main sections:
Page Rendering lists user interface controls and logic that are executed when a page is rendered. Page Rendering is the process of generating a page from the database. See "Using Page Rendering Icons".
Page Processing lists logic controls (such as computations and processes) that are evaluated and executed when the page is processed. See "Using Page Processing Icons".
Shared Components lists common components that can be used by one or more pages within an application. See "Using Shared Components Icons".
