Hi Simon,
currently what you want is a bit tricky to do due to the fact that the
methods in TRootGuiFactory are not virtual. So what you need to do:
- derive from TGuiFactory a class TMyGuiFactory.
- copy complete contents from TRootGuiFactory to TMyGuiFactory.
- change CreateBrowserImp to create your TMyRootBrowser instead of a
TRootBrowser.
- in your application before creating any browser call:
gGuiFactory = (TGuiFactory *) gROOT->ProcessLineFast("new
TMyGuiFactory();");
That should do it.
I've made the methods in TRootGuiFactory virtual in the dev version in
cvs, this will allow you to derive your TMyGuiFactory directly from
TRootGuiFactory and allows you to override the CreateBrowserImp methods.
For the rest you need to do the same to activate your TMyGuiFactory.
Cheers, Fons.
