Qt Gamepad documentation
-
Hi and welcome to devnet,
Looks like you are searching for the QGamepadManager class which looks like it has its documentation missing. However a quick look at the module examples should get you going.
Hope it helps.
-
You can use QMetaType inspection to get all signals and then filter them by name before creating the connections.
-
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.
-
What OS are you on ?
-
Did you check that the plugin get correctly loaded ?
-
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.

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
-
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". -
