copied!<p>It looks like on windows, the scrolledWindow was the right place to watch for scroll events instead of the main window.</p> <p>Using the following modification, I was able to handle scroll events on windows 7.</p> <pre><code>#include <gtkmm.h> #include <iostream> class MyScrolledWindow : public Gtk::ScrolledWindow { public: bool on_scroll_event(GdkEventScroll *e) { std::cout << "scrollEvent" << std::endl; return false; } MyScrolledWindow() { } }; class MyWindow : public Gtk::Window { Gtk::EventBox event_box; MyScrolledWindow scrolled; public: bool on_button_press_event(GdkEventButton *b) { std::cout << "button press" << std::endl; return false; } MyWindow () { add(scrolled); scrolled.add(event_box); set_default_size(640, 480); show_all(); } }; int main(int argc, char** argv) { Gtk::Main kit(argc, argv); MyWindow window; kit.run(window); return 0; } </code></pre> <p>====== Old Answer: ================</p> <p>I am not able to reproduce your isse. This is the code I used to try to reproduce your issue:</p> <pre><code>#include <gtkmm.h> #include <iostream> class MyEventBox : public Gtk::EventBox { bool on_button_press_event(GdkEventButton *b) { std::cout << "button press" << std::endl; return false; } bool on_scroll_event(GdkEventScroll *e) { std::cout << "scrollEvent" << std::endl; return false; } }; int main(int argc, char** argv) { Gtk::Main kit(argc, argv); Gtk::Window window; MyEventBox eventBox; eventBox.show(); window.add(eventBox); kit.run(window); return 0; } </code></pre> <p>For compiling, I used the folowing command line (using Linux):</p> <p><code>g++ main.cpp $(pkg-config --cflags --libs gtkmm-3.0)</code></p> <ul> <li>If you can reproduce your issue using this minimum example, the problem might be platform specific and a workaround using the window's/event box' <code>Gdk::Window</code> might be necessary.</li> <li>If you can't reproduce your issue using this code, the issue is caused somewhere else in your code and you'll need to post more information.</li> </ul>
