* Modified a few lines from BSession::WriteInt32( uint32 ) into WriteUInt32( uint32 )
* in updateCachedState(), now all font attributes are received at once; I realized app_server doesn't need the flag based system. :-) * added a new method: PrintToStream() - used for debugging. * now the view state is allocated and initialized in BView::InitData(...) * modified a few things in addToList(...) 'cause I don't know what was in my head when I wrote it?! * added _ReservedView2-18() methods because of linker errors. * a new method used for debugging: PrintTree() * added debugging messages for a few methods * TESTED view hierarchy methods like AddChild() and RemoveChild() RemoveSelf() - They WORK! :-))) * minor but significant :-) ( = instead of == ) change in findView(...) *** Tree structure is in place now, mirrored on app_server ... and working :-) git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4684 a95241bf-73f2-0310-859d-f6bbb57e9c96
