UI Objects

Learn how to setup UI Objects Callbacks

Button Object Callbacks

Button objects offer three callbacks

OnMouseEnter : called when the mouse comes hover the button
OnMouseLeave : called when the mouse leaves the button surface
OnMouseClick : called when you click on the button

Those three callbacks are setup using lambda functions. The signature used is : std::function<void()>, which means a function with no parameter returning void.

//Retrieve your button as generic Object
nero::Object::Ptr object = getObjectManager()->findScreenUIObject("screen_name", "button_name");
//Convert back to Button Object
nero::ButtonObject::Ptr my_button = nero::ButtonObject::Cast(object);

//Set up your callbacks using lambda functions
my_button->setOnMouseEnter([this]()
{
    //do something, play sound, etc.
})
my_button->setOnMouseLeave([this]()
{
    //do something, play sound, etc.
})
my_button->setOnMouseClick([this]()
{
    //do something, play sound, etc.
})
