【转帖】selecting In Odamfcapp
 

selecting in odamfcapp
selecting in odamfcapp
i want to implement selecting in my application, i wanted to base on solution from odamfcapp, but i see that what is selected there is topmost block reference rather than single element in block. situation is more complicated, when element is in model space and we have a displayed layout with viewport on that modelspace. then, selection in odamfcapp does not work at all.
i think the problem is that the library does not provide any simple way to get real coordinates (or suitable transformation), having only oddbentityptr of given entity. are you going to introduce such functionality in future releases?
i can provide sample dwg file with viewport that elements are not selectable.
hi,
these issues are odamfcapp's limitations.
1. odgsview::select() allows to select on each level of scene graph. odamfsapp selection handler cut down nested entities.
2. when paper layout is displayed in odamfcapp -- paperspace view is always active one -- so only paper space entities can be selected.
3. when handling odgsselectionreactor::selected() callback all odgsview's transformations can be obtained via pointer to view currently selecting in.

dear dmitry a. novikov,
can i know how to open drawings in model space by default. how to set the model space as the default view..

call oddbdatabase::setcurrentlayout() function.
e.g.:
code:
oddbblocktablerecordptr pmodelblock = pdb->getmodelspaseid().safeopenobject();
pdb->setcurrentlayout(pmodelblock->getlayoutid());
