Yep..

All you need to do is to make your KLibFactory based shlib export a
KPropsPage, create a service .desktop file for your properties dialog
plugin and make it implement the KPropsDlg/Plugin servicetype and a
mimetype. Then you'll get the KPropertiesDialog as parent object for your
KPropsPage object. You can then use the dialog() method of
KPropertiesDialog to get a reference to the KDialogBase and then call
addPage to insert your tabs (note the plural :) . Also make sure to emit
the changed() signal whenever the user edited something in your
tabwidgets, in order to make KPropsDlg properly call applyChanges() when
the user presses apply. (-> applyChanges is called on on those plugins
that emitted the signal at least once, in order to avoid unnecessary
applyChanges() calls (->less disk traffic, etc.) .


As David already mentioned: Have a look at the document info properties
dialog plugin in koffice/lib/kofficecore/ :)

Bye,
 Simon
