- added an icons "insertPoint.png",
- added a new html file for the about dialog of Delaunay triangulation,
- the Voronoi diagram is now painted in blue,
- add the button for Voronoi,
- general cleaning of the code.
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")
- Add dgi and vgi at the beginning, and use show()/hide() instead of
addItem/removeItem.
- Merge connectActions() into MainWindow's constructor. That is clearer
like that.
- Add comments in the constructor.
- Rewrite the two action handlers aboutCGAL and aboutDemo: use html file
in a resource. That works! The "About CGAL" dialog now has a big shiny
CGAL logo! :-)
- Use fh as an hint, to avoid to localize the moving point without hint
each time it moves.
- Code factorisation between mousePressEvent and mouseMoveEvent.
