Hello,
I'm trying to create a viewer based on the inkscape SVG viewer. I based my viewer on the code in inkview.cpp. But during execution I always get a segmentation fault when I call sp_document_new. I create a LayoutRenderer and on that object I call the function renderLayout.
Here's some part of the code I use:
LayoutRenderer::LayoutRenderer() { changed = false; uriLatest = "latest.svg"; vector<string> result; vector<string>::iterator it; result = Util::putFileInVector(uriLatest); latest = ""; it = result.begin(); while(it != result.end()) { latest += *it + "\n"; it++; } Inkscape::GC::init(); setlocale (LC_NUMERIC, "C"); if (result.size() > 0) { changed = true; } }
void LayoutRenderer::renderLayout() { cout << "Start rendering \n"; GtkWidget * w = gtk_window_new (GTK_WINDOW_TOPLEVEL); cout << "Created new window\n"; SPDocument * doc = sp_document_new (uriLatest.c_str(), TRUE, TRUE, false); cout << "Created new document\n"; GtkWidget * view = sp_svg_view_widget_new (doc); cout << "Created new view\n"; cout << "rendering created objects \n"; sp_svg_view_widget_set_resize (SP_SVG_VIEW_WIDGET (view), FALSE, sp_document_width (doc), sp_document_height (doc)); sp_document_ensure_up_to_date (doc); sp_document_unref (doc); gtk_widget_show (view); cout << "rendering add to container\n"; gtk_container_add (GTK_CONTAINER (w), view);
gtk_widget_show (w); cout << "Start rgoing to main loop\n";
gtk_main ();
}
The function gtk_init (&argc, (char ***) &argv); has been called prior to all the rendering calls. This is the output I get: Start rendering Created new window Segmentation fault
Any help is welcome?
