Hello Eliel

First replace the cluster constant (Range Constant) in the block diagram of the attachment by a cluster control, then you substitute the numeric controls inside the cluster by horizontal or vertical Pointer Slider.

With the User Interface Event Handler design pattern (Event Structure) you'll be able to see the image modifications every time you hit the threshold button, if you want to see these changes more dynamically, when you click the threshold button once, I think you could use the State Machine design pattern. If don't know how the state machine design pattern works very well, please see the link below that's a tutorial about it.

Hope it helps you

Hello Eliel.

Yes, this way also works, but you can just right click in the Range constant and select the option change to control from the shortcut menu. And then, in the front panel, you can right click in the numeric controls inside the cluster and select replace, to change them by the other types of controls like these ones you are already using.

like this in the attach.
