determine oddbentity type
determine oddbentity type
following code:
oddbobjectiteratorptr it = pblock->newiterator();
for (it->start(); !it->done(); it->step())
{
oddbentityptr pent = it->objectid().safeopenobject();
if( pent->iskindof( oddbline::desc() ) )
{
}
}
so this works! but i would prefer another way like:
switch( pent->getentitytype() )
{
case oddbentity::kline:
case oddbentity::kcircle:
}
couldn't find anything!
any suggestions?
thanx

you can eighter initialize a map<odrxclass*,somefunctionpointer> and to maintain it by your self, or to use the extension classes functionality provided by dwgdirect.
or just the if,else,if,else structure. but the extension classes would be the reccommended solution in this case.
hope this helps.

hi thanx,
but what do you mean by extension classes how to use them?
an example would be nice!
thanx

protocol extensions is a method to add your own interface to rxobjects.
using protocol extesions is illustrated in odreadex sample.

oh so now i understand but it seems like this works also with the desc()
is this right?
greets and thanx again

desc() returns pointer. it will work with if() else if()...
but not with switch-case.
