What is the correct way to subscribe for an event?

Event notification is a vital aspect of GUI programming. CEGUI handles those using subscribers. In order to subscribe a window for an event, you have to call the method 'Window::subscribeEvent', passing the function to be called when the specified event occurs, and the instance on which the method is called.

Code: Select all

class MyButtonHandler
{
private:
    PushButton* mButton;

public:
    MyButtonHandler::MyButtonHandler(PushButton* btn) : mButton(btn)
    {
        btn->subscribeEvent(PushButton::EventClicked, Event::Subscriber(MyButtonHandler::ButtonClicked,this));
    }
   
    MyButtonHandler::ButtonClicked()
    {
        //This function gets called when the button is clicked
        std::cout << "Button clicked" << std::endl;
    }
