Re: Gio::Action lookup crash

[Phil Wolff <adiabat centurylink net>]

The following modification produces the expected result:

#include <gtkmm.h>
#include <iostream>

class App: public Gtk::ApplicationWindow
{
    public:
        App()
        {
            add_action("int");
        }
    virtual void on_realize ();
};

void App::on_realize ()
{
    Gtk::ApplicationWindow::on_realize ();
    auto la = lookup_action("int");
    std::cout << bool(la) << std::endl;
}

int main(int argc, char *argv[])
{
    auto app = Gtk::Application::create(argc, argv, "test.gtk");
    App win;
    return app->run(win);
}
