<view id="com.ibm.btt.rcp.views.NavigatorView" relationship="left" ratio="1.0" refId="editarea" />
<folder id="integration" relationship="right" ratio="0.28" refId="com.ibm.btt.rcp.views.NavigatorView">
<page id="com.ibm.btt.rcp.views.WorkingAreaView:com.ibm.btt.rcp.sample.ExcelActivity" holder="true"/>
<page id="com.ibm.btt.rcp.views.WorkingAreaView:com.ibm.btt.rcp.sample.website" holder="true"/>
</folder>
<folder id="workarea" relationship="bottom" ratio="0.4" refId="integration">
<page id="com.ibm.btt.rcp.views.WorkingAreaView:com.ibm.btt.rcp.sample.logo" holder="true" moveable="false" closeable="false"/>
<page id="com.ibm.btt.rcp.views.WorkingAreaView:*" holder="true"/>
</folder>
</perspectiveDef>
