Signal & Slots with ComboBox

[Jack_Holmes]

Hello. I am new to Qt and I am trying to use signals and slots.

I have a ComboBox which is part of my UI and has pre-filled values. When I change the value of the ComboBox I would like it to call a function.

This is what I have tried to do (called in my QMainWindow class):

QObject::connect(m_ui.cmbResolution, SIGNAL(currentIndexChanged(int)), this, SLOT(setGameWindowResolution()));

QObject::connect(m_ui.cmbResolution, SIGNAL(currentIndexChanged(int)), this, SLOT(setGameWindowResolution()));

To copy to clipboard, switch view to plain text mode 

It's also worth mentioning that I tried to do this with a menu item which worked fine:

QObject::connect(m_ui.actionAdd_Empty, &QAction::triggered, m_pSceneManager, &SceneManager::addEmptyGameObject);

QObject::connect(m_ui.actionAdd_Empty, &QAction::triggered, m_pSceneManager, &SceneManager::addEmptyGameObject);

To copy to clipboard, switch view to plain text mode 

Any help would be greatly appreciated, thanks.

EDIT:
Ok - finally got this working. I needed to put my function definition in 'public slots:'
