Use Gtk::GestureClick. Some examples:

https://gitlab.gnome.org/GNOME/gtkmm-documentation/-/blob/master/examples/book/popover/examplewindow.cc
In most (perhaps all) situations where event signals have been used in
gtkmm3, use one of the many subclasses of Gtk::EventController.

Hello,
I hope this is the right place for this, sorry if not!
I'm trying to implement an example gtkmm 3.0 code in gtkmm 4.0 and ran
into a problem. The goal is to get the cursor's coordinates and what
type of click occurred when clicking on a button. In gtkmm 3.0, I
could use|GdkEventButton|, as in this example from thedocs
<https://developer-old.gnome.org/gtkmm-tutorial/unstable/gtkmm-tutorial.html#sec-xeventsignals>:
|bool on_button_press(GdkEventButton* event); Gtk::Button
button("label"); button.signal_button_press_event().connect(
sigc::ptr_fun(&on_button_press) ); |
But |GdkEventButton| seems to no longer exist or no longer be
accessible in gtkmm 4.0.
There is a reference to GdkEvent API changes in the migration
documentation <https://docs.gtk.org/gtk4/migrating-3to4.html>, but I
still do not understand how to migrate that example code. Is anyone
more familiar or has any sort of related example?
I've also posted this on stack overflow:

Thanks for your help,
Aaron
