QGraphicsView*. It is now able to handle several graphics view at the same
time (just install several event filters).
New class CGAL::Qt::DemosMainWindow. That class has several protected
methods:
void setupStatusBar();
void addNavigation(QGraphicsView*);
void setupOptionsMenu(QMenu* menu = NULL);
void addAboutCGAL(QMenu* menu = NULL);
void addAboutDemo(QString htmlResourceName, QMenu* menu = NULL);
setupStatusBar() adds a label in the statusBar(), that is connected to the
navigation class, and shows the position of the mouse.
addNavigation(QGraphicsView* v) adds a navigation class to the view v.
setupOptionsMenu(QMenu* m = NULL) adds two options "Use OpenGL" and
"Use antialiasing" to the menu m. If m==0, a menu named "Options" is searched
for, or created if it does not exists.
addAboutCGAL(QMenu* m = NULL) adds an entry "About CGAL..." to the menu
m. If m==0, a "Help" menu is searched for or created.
addAboutDemo(QString htmlResourceName, QMenu* m = NULL) adds an entre
"About the demo...", to the menu m. If m==0, a "Help" menu is searched for
or created. If the entry is clicked, a popup dialog shows the content of
the resource/file whose name is in htmlResourceName.
Example:
addAboutDemo(":/cgal/help/about_triangulation.html")
