The QPR Portal main window consists of five elements: the Tabs, the Toolbar, the Navigation Frame, the Viewing Frame, and the Details Pane.
The Navigation Frame is used to navigate through the models, the Viewing Frame and the Details Pane show information from the models (e.g. the Hierarchy View or descriptions), the Tabs open different views (e.g. the information related to your responsibilities is in the My Contents tab), and the Toolbar contains commands used in QPR Portal.
