Sorry, I meant "BUTTON1_MOTION_MASK," but it doesn't really matter.
Yes, it does matter. Like you say, you have
BUTTON1_MOTION_MASK, but you should have BUTTON_PRESS_MASK.
Button motion is not the same as button press. First a button is
pressed, then the pointer is moved with the button pressed, then
the button is released. That's three different kinds of events.
Alternatively, you can set
Gdk::BUTTON1_MOTION_MASK and connect to
signal_motion_notify_event(). Or set several mask bits and connect
to several event signals. Anyway, you must set a mask bits that
correspond to the event signals you connect to.

But do I not have
get_window()->set_events(Gdk::EventMask::BUTTON1_PRESS_MASK);
on line 21?
2019-03-01 11:03 GMT+01:00, Kjell Ahlstedt <kjellahlstedt gmail com>:
get_window()->set_events(Gdk::EventMask::BUTTON_PRESS_MASK);
or
add_events(Gdk::EventMask::BUTTON_PRESS_MASK);
If you want to receive button press events, then set the button press
mask. If you want to receive button motion events, then set a button
motion mask.
It's usually better to use Gtk::Widget::add_events() instead of
Gdk::Window::set_events() or Gtk::Widget::set_events().
If you don't want other handlers to receive the event, then it's correct
to let draw_get_mouse() return true.

I did what you said but it didn't work for me. I changed
signal_button_press_event().connect(sigc::mem_fun(*this,
&DrawingArea::draw_get_mouse));
to
signal_button_press_event().connect(sigc::mem_fun(*this,
&DrawingArea::draw_get_mouse), false);
but nothing changed. I also tried changed return value of
draw_get_mouse to false even though I don't want to propagate that
signal to other handlers.
I'm also sending modified code, which is also available here:
