Re: [gtkmm4] Help on DrawingArea plus Mouse Activity

[Mj Mendoza IV <mj mendoza iv gmail com>]

Hi Andrew!

Thanks for porting the demo code.  I saw the GTK version earlier but I'm not familiar on Gtkmm4 API to actually port the GTK version.  I'm still halfway in porting my code, but I can draw now so I feel like it's better progress now than without your gtkmm ported version of the GTK demo.

Kjell thanks for the link.  I've always been referring to the developer-old gtkmm tutorial -- I'm still wondering why it's developer-old -- prolly cooking something new?

I've tried the Cairo-based Clock demo, and adjusted my code to reflect needed changes to port to gtkmm4.  Now, I'm currently missing mouse activities.

In addition to what Andrew Potter suggested, if you want to track all mouse movements, use Gtk::EventControllerMotion.

Just about everything that was done in event signal handlers in gtkmm3 is now done with the many subclasses of Gtk::EventController.

I've read the gtkmm4 changes section of the tutorial (https://developer-old.gnome.org/gtkmm-tutorial/unstable/gtkmm-tutorial.html#changes-gtkmm4) but content is more of a note than actual information for beginner porters like me.

I don't think anyone will ever take the time to write a real migration guide from gtkmm3 to gtkmm4.

The documentation at developer-old.gnome.org is not updated any more. If you want to see the latest version of the gtkmm4 tutorial, look at https://gnome.pages.gitlab.gnome.org/gtkmm-documentation.
