Hi Carsten,
Currently button 'Reset' on Dialog Tools->Customize->Keyboard is to
restore the default shortcuts for an application/module. when
implementing the reset feature for the XCU based configuration
accelerators, we shouldn't try to remove the whole Accelerators.xcu in
the user layer, because the Accelerators.xcs contains all the module
depending accelerators entries. And now I have three ideas:
1)remove the entry(e.g.: <node
oor:name="com.sun.star.text.TextDocument" oor:op="replace">) from the
user layer's Accelerators.xcu, using configuration API. But currently
removeByName(XNameAccess) is to OVERRIDE the lower entry, not to
REMOVE the entry indeed from the already merged XCU.
Is there API can be used to restore the default data for set node? I
found an implementation like doDifferenceToDefaultState(...) in the
configmgr, but found no such UNO API.
2)would the the XML API(e.g.: XNode->removeChild), which has already
an implementation in module unoxml, be an choice to remove an node
from an XCU(XML) file?
3)create a new duplicated default Acelerators.xcu, to compare the
AcceleratorsDefault.xcu and Accelerators.xcu, then write the diffs to
configuration. But as for performance, this solution wouldn't be
better than 1) and 2).
What's your opinion?
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.
Regards,
Carsten
