The Yaoqiang XPDL Editor user interface consists of several parts. The order and the number of the displayed parts depend
on the actually used configuration. This chapter explains the default configuration layout.

Right below the title line of the editor window you will see the main menu, the main tool bar. The rest of the window contains
different components. The components are placed in the corresponding are depending on their type.

Each component is responsible either for providing a different view of the WfMC XPDL elements, for displaying some
additional information about XPDL elements (such as validation problems) or for displaying the result of some search.

Figure 2.1. Default configuration layout

There are two areas on the left hand side: The upper area (marked as "Special Area") contains the Graph overview,
the External package relations and the Transient package pool components. The lower area (marked as "Tree Area") contains
the tree type components Navigator and Package tree.

There are also two areas on the right hand side: The upper area (marked as "Main Area") contains the Graph and the XPDL
View components. The lower area (marked as "Other Area") contains the Problems, Search and LDAP components.

(NOTE: by right-clicking on the tab you are able to close some component's view or to move it from one area to another)
