Hi Carsten,
Hi Yan,
You should use the HierarchyAccess (look at
com.sun.star.configuration.HierarchyAccess) service of the configuration
which provides a com.sun.star.beans.XMultiPropertyState interface. There
you can call setAllPropertiesToDefault(). According to Joerg Barfurth,
the inventor of the OpenOffice.org configuration implementation, this
should be possible for whole sets. It's not clear how well this part of
the implementation is tested, therefore you have to try out.
Solution 2 or 3 are nothing one would like to implement. We clearly need
support for this kind of operation from the configuration itself.
1)Currently, we can reset an updatable property to its default state for
group nodes, which support the interfaces
com.sun.star.beans.XPropertyState and
com.sun.star.beans.XMultiPropertyStates.
2)Individual set elements can not be reset because set nodes do not
support com.sun.star.beans.XPropertyState, while the confiuration
service supporting com.sun.star.beans.XPropertyWithState can be used to
reset the set as a whole.
1) and 2) have been documented in our
DevelopersGuide(http://wiki.services.openoffice.org/wiki/Documentation/DevGuide/Config/Updating_Configuration_Data)
And I wrote a marco as following, using method
setAllPropertiesToDefault() for a group node and found it works fine.
BUT set node still can not be removed indeed, using method
setToDefaultAsProperty(). The result is just like:
<node oor:name="Windows">
<node oor:name="SplitWindow0" oor:op="remove"/>
<node oor:name="SplitWindow2" oor:op="remove"/>
<node oor:name="SplitWindow1" oor:op="remove"/>
<node oor:name="SplitWindow3" oor:op="remove"/>
</node>
Besides, to iterate over the nodes of a set doesn't work correctly when
a set node of the user layer doesn't exist in the default layer.
So I suppose the feature for retrieving default value for set nodes is
still missing in the configmgr at present. Could you investigate it further?

Sub retrieveDefaultCfgValue
Dim rProps(1) as new com.sun.star.beans.PropertyValue
aConfigProvider =
createUnoService("com.sun.star.configuration.ConfigurationProvider")
rProps(0).Name = "nodepath"
rProps(0).Value = "org.openoffice.Office.Common"
rProps(1).Name = "locale"
rProps(1).Value = "*"
aConfig =
aConfigProvider.createInstanceWithArguments("com.sun.star.configuration.ConfigurationUpdateAccess",
rProps())
obj = aConfig.getByHierarchicalName("Misc")
if hasUnoInterfaces(obj, "com.sun.star.beans.XMultiPropertyStates") then
obj.setAllPropertiesToDefault()
endif
aConfig.commitChanges()
rProps(0).Value = "org.openoffice.Office.Views"
aConfig =
aConfigProvider.createInstanceWithArguments("com.sun.star.configuration.ConfigurationUpdateAccess",
rProps())
obj = aConfig.getByHierarchicalName("Windows")
if hasUnoInterfaces(obj,"com.sun.star.beans.XPropertyWithState") then
obj.setToDefaultAsProperty()
endif
aConfig.commitChanges()
End Sub
