This is the second attempt at "reusing the existing uDig workbench but let me change some stuff story". In general the use of these hacks is discouraged please make your own Application following RCP conventions.

The extentions point here is net.refractions.udig.ui.workbenchConfigurations:

<extension
          point="net.refractions.udig.ui.workbenchConfigurations">
       <workbenchConfiguration
             class="net.refractions.udig.internal.ui.UDIGWorkbenchConfiguration"
             id="net.refractions.udig.internal.ui.UDIGWorkbenchConfiguration"/>
    </extension>

By implementing this extention in your own application you may specify an instance of WorkbenchConfiguration. If you do not supply a configuration the default UDIGWorkbenchConfiguration will be used.

The UDIGWorkbenchWindowAdvisor delegates to this code as part of preWindowOpen it is used to perform the following:

• showCoolBar = true
• showStatusLine = true
• showFastviewBars = true
