event system is a core cegui fonctionnality, you have to understand it.

Basicly, you tel to the event system that a button event react by a callback to a fonction :



For more info, you should look in the FAQ at the question "What is the correct way to subscribe for an event?"

and in the API Reference in the CEGUI:EventSet class reference, the subscribeEvent fonction is the three before the end.

Hope it help.

you should do something like making the midle value of you'r slider the default value.

for example, you want you'r slider control camera from -10 to 10, so you'r middle value is 0.
But because the slider widget can manage only positive value, you have to translate (with some helper fonctions) to 0 |-| 20 and make you'r middle value 10.

finely yourslider->setCurrentValue(10.0f) and the thumb will be in the middle.
