While implementing that framework, I encountered technical problem.
We use KCModules and KSettings::Dialog. Can the changes in
one page be reflected into other page without reopening the config
dialogbox?

For example, in central variable config page (maybe "project general"),
suppose that user added a group named "debugconfig". And the user
switch into "MakeBuilder configuration" page and try to set the
"debugconfig" as a default variable setting.
Although "debugconfig" is saved into .kdev4 file, it is not reflected
in plugin config widget
because plugin widget has no way to be notified such changes.
