I think you must wait using disableResize() until right before exec(). It seems
to me (I have looked in kmainwidget.cpp) that you change the dialog
contents/size after the PreferencesDlg constuctor.

so try this:

PreferencesDlg dlg; // without disableResize() !!
//<lot of stuff that change the size of the dialog>
dlg.disableResize();
int ret = dlg.exec();

and give the dialog a parent different from 0 (eg, PreferencesDlg dlg(this) )

Once you clik on the link it will execute what has been defined by
dlg.setHelp( <url>, <topic> )

The problem is that this url is shared with what the "Help" button uses
so this issue needs to be refined later. The link could provide another link 
than what the "Help" button does.
