    And if I want to connect all signals button...Changed to one slot, should I connect them one by one? Or I can get list of buttons and connect it to slot in a loop?

      You can use QMetaType inspection to get all signals and then filter them by name before creating the connections.

        And I tried examples, and Qt doesn't see some of my gamepad keys. I use Genius g-08-xu gamepad. It works perfectly in another software, but Qt doesn't see buttons 3 and 6.

          And I tried this example: http://www.ics.com/blog/whats-new-qt-570-qt-gamepad but it says that I have only one gamepad, but I have connected two gamepads. If I press any button in one of them, it prints a message that button was pressed, but shows the same device ID. And 3 and 6 buttons on Genius g-08-xu don't work with this example too.

              Linux. I tried on Windows (minGW) too, but it doesnt't work at all. Examples don't see any gamepads.

                    Add QT_DEBUG_PLUGINS to the environment variables in the Run part of the Project panel and set it to 1.

                    You'll have more information on the debug output.

                          Hi, if you're compiling in Debug mode, try instead to compile in Release mode.

                              Hmm, I checked and it seems Qt Gamepad does not support all the different gamepads available on WIndows :-( I.e. the plugin loads fine but no gamepads are detected, more discussion here

                              Also you can try emulating a Microsoft device like an Xbox360-controller, for example I can use my Playstation4 controller by installing DS4Windows

                                I'll try it later.

                                But why Qt can support only part of gamepads? My gamepads are very old and work both in Windows and Linux without additional drivers.

                                  DS4Windows doesn't see my gamepads. But Windows Control panel sees and shows pressed buttons.

                                    Because your gamepad is 12 years old (or more) I think it doesn't support the standard DirectX interface, only Windows control panel, that's why Qt is blind to it.
                                    Also, when playing a 64-bit (only) game like BattleField1, I think such game will exhibit the same problem as Qt, i.e. not see your gamepad :-(

                                      I work at Win10 64 bits and QT5.7.0 ,msvc14。It canwork at this code.
                                      Gamepad::Gamepad(QObject *parent) : QObject(parent)
                                      , m_gamepad(0)
                                      {
                                      m_gamepad = new QGamepad(0,this);//or just m_gamepad = new QGamepad; is ok//
                                      connect(m_gamepad,&QGamepad::connectedChanged,this,&MMGamepad::connectedChangedEvent);
                                      qDebug() << "A new gamepad:"<<m_gamepad->isConnected();// when start is false
                                      }
                                      void Gamepad::connectedChangedEvent(bool value)
                                      {
                                      if(value)
                                      {
                                      qDebug() << "Gamepad:: decive is connect!" ;
                                      }
                                      else
                                      {
                                      qDebug() << "Gamepad:: decive is disconnect!" ;
                                      }
                                      }
                                      and you can get any signal after"Gamepad:: decive is connect".

                                        connectedChangedEvent

                                        also remenber "QT += gamepad" in .pro and #include <QtGamepad/QGamepad>
