[gtkmm4] Help on DrawingArea plus Mouse Activity

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

Hi,

I'm porting a 2D Animation Software from gtkmm3 to gtkmm4.

As a drawing tool, it heavily relies on Gtk::DrawingArea and mouse activities (movements and presses).  I got the keyboard activity working from a different code demo.

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.

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.  By any chance, does someone have a snippet of DrawingArea where mouse activities are currently handled?  I believe I could work on that and be on my merry way.

I've tried the IRC but there's no activity at all.  I tried the gtk channel but could only be helpful to a certain extent.
