from odlylayerfilterptr to odlylayergroup
from odlylayerfilterptr to odlylayergroup
could not find how to reach the layer list in a leaf layerfilter.
i do this :
odlylayerfiltermanagerptr paclayergroupstree= odlygetlayerfiltermanager( pdb);
odresult err= paclayergroupstree->getfilters(prootlayergroups,pcurrentlayergroup) ;
odlylayerfilterarray paclayergroupsarray= prootlayergroups->getnestedfilters();
....
odlylayerfilterptr thecombination= paclayergroupsarray[i];
and now how do i get the odlylayergroup for this layerfilter ?
thanks for any help
try this:
odlylayergroup *group = (odlylayergroup *) thecombination.get();
oddbobjectidarray ids = group->layerids();
hi,
[dwgdirect version 2.04.02, windows 32 bits, ms visual c6]
i am appending these codes to the odreadex:
/****************/
odlylayerfilterptr prootlayergroups,pcurrentlayergroup;
odlylayerfiltermanagerptr paclayergroupstree=
odlygetlayerfiltermanager(pdb);
odresult err= paclayergroupstree->getfilters(prootlayergroups,
pcurrentlayergroup) ;
odlylayerfilterarray paclayergroupsarray=
prootlayergroups->getnestedfilters();
for ( unsigned int i = 0; i < paclayergroupsarray.length(); i++ )
{
odlylayerfilterptr thecombination= paclayergroupsarray[i];
odlylayergroup *group = (odlylayergroup *) thecombination.get();
oddbobjectidarray ids = group->layerids();
}
/*****************/
but the call to group->layerids() gives me an exception.
have the codes changed in this new release "dwgdirect version 2.04.02"
any suggestion will be greatly appreciated.
many thanks,

does the code fail for any file?
are you sure there are only group filters? (what isidfilter() returns?)
