问题 I am using the gtkmm library with C++, and I am trying to create a signal which allows to change current tab, but it does not work. Actually I think the problem comes from this line: menuit->signal_activate().connect([&bo]() {bo->next_page();}); Where: menuit = Gtk::MenuItem bo = Gtk::Notebook The code compiles well, but when executing I get this line : Segmentation fault (program exited with code: 139) Thank you a lot for your help ! 回答1: menuit->signal_activate().connect([&bo]() {bo->next

问题 I am working through the gtkmm documentation. I have started by trying to compile the "Simple Example". Here is the code. It can also be found here. /// SimpleExample.cpp #include <gtkmm.h> int main(int argc, char *argv[]) { auto app = Gtk::Application::create(argc, argv, "org.gtkmm.examples.base"); Gtk::Window window; window.set_default_size(200, 200); return app->run(window); } I have tried to compile this using g++ SimpleExample.cpp -o SimpleExample `pkg-config gtkmm-3.0 --cflags --libs`

Cannot embed gnuplot x11 window into Gtk3 socket

问题 I'm creating Gtk::Socket in my Gtk3 (actually, gtkmm) application and trying to embed gnuplot's window into it. But it does not work: the socket remains to stay as a black rectangle, while gnuplot window appears standalone elsewhere. Meanwhile, Gtk::Plug plugs into this socket perfectly. In Gtk2 this trick with gnuplot works well too. Here is socket.cpp #include <iostream> #include <fstream> #include <gtkmm.h> #include <gtkmm/socket.h> using namespace std; void plug_added(){ cout << "A plug

catch mouse motion in gtkmm

问题 I am trying to catch the mouse motion when I hold the mouse middle button. The goal is to implement a rotation feature in an stl viewer. I found the event mask BUTTON2_MOTION_MASK . But I have a hard time figuring out which signal catches it. Here's the two line I use to create and hook the event. These two line are inside a GtkApplicationWindow Constructor. glWidget.add_events(Gdk::BUTTON2_MOTION_MASK); glWidget.signal_motion_notify_event().connect(sigc::mem_fun(*this,&mainWindow::rotate));

问题 I am trying to port my application from linux to windows and I have a problem with theming. In linux this works out of a box, just compile it and application is using good theme and looks native. I have installed gtkmm3 and gtk3 in MSYS2 and I am building it with CMake. This is OK, I had to copy all dlls to directory with binary to be able to execute it. I did not copy anything else. I am trying to create "unzip and execute" package. My problem is, that application looks out of place. It does
