winopengl vectorizer broken for changing active layout
winopengl vectorizer broken for changing active layout
hi,
i am not able to refresh the drawing when changing active layout using winopengl vecotrize device. to recreate the issue follow these steps:
1. open odamfcappdll.exe
2. create new drawing or open any existing drawing.
3. change vectorize device using vectorize->winopengl.gs menu item.
4. vectorize the drawing.
6. change active layout using view->set active layout... menu item.
the drawing doesn't refresh and can't draw any entity in drawing. sometimes it crashes the program too.
is this a bug in winopengl library or in the odamfcapp? how to fix it?
thanks.
hi,
it's limitation of odamfcapp sample that it does not reinitialize gs when layout is switched. and it's a bug that odamfcapp is crashed.
the easiest way to reinitialize gs is to recreate cdwgviewer. next lines do this:
code:
cframewnd* pframe = (cframewnd*)theapp.getmainwnd();
pframe = (cframewnd*)pframe->getactiveframe();
cview* pview = pframe->getactiveview();
if(pview->iskindof(&cdwgviewer::classcdwgviewer))
{
pframe->sendmessage(wm_close, 0, 0);
theapp.getmainwnd()->sendmessage(wm_command, makelong(id_vectorize,0), 0);
}
add them into codamfcappdoc::onviewsetactivelayout() after line:
code:
m_pdb->setcurrentlayout(odstring(dlg.m_snewlayoutname));
