if the value of scrollbar is changed(signal is emited), then show the image, which its number in image set is the value of scrollbar.

for example, there are 40 images I want to show on the label. then the range of scrollbar is 1-40(actually 0-39).

I am not sure how to fresh the label. certainly it is the first time I am trying to design a GUI. so if you have suggestion, please tell me. thanks a lot.

How do you react to the scrollbar changes?
