Hello everyone! i’m a new on processing forum.
I make a Scrolablelist from ControlP5 library and I would like to change via code the selected item:
```auto
import controlP5.*;
import java.util.*;
ControlP5 cp5;
void setup() {
size(400, 400);
cp5 = new ControlP5(this);
List l = Arrays.asList("a", "b", "c", "d", "e", "f", "g", "h");
/* add a ScrollableList, by default it behaves like a DropdownList */
cp5.addScrollableList("dropdown")
.setPosition(100, 100)
.setSize(200, 100)
.setBarHeight(20)
.setItemHeight(20)
.addItems(l)
.setType(ScrollableList.LIST) // currently supported DROPDOWN and LIST
;
}
```
my intention is something similar to:
```auto
cp5.setItemSelected(2);
```
as if I had manually selected the second item.
I thank you in advance who can help me,
regards!

Hi,
You can check out the doc. There are the list of all available functions: [http://www.sojamo.de/libraries/controlP5/reference/index.html](http://www.sojamo.de/libraries/controlP5/reference/index.html)

You also have the setItem() one if you know the name of the item and if I’m not mistaken.

Excuse my ignorance but i can’t find the method, isn’t in a list methods that appear with autocomplete code. There another way to use this methods?

Here they are:
```auto
setItems(java.util.List theItems)
setItems(java.util.Map theItems) |
setItems(java.lang.String[] theItems)|
```
I never tried them though so it is really just a guess based on there name.
I’m currently using the `setValue()` function in one of my sketch and it works like a charm 🙂

I try but not sure if it is possible. Add the following to cp5:
```java
.setValue(1)
.open()
```
This sets the value display in the list when the list is close. Calling open forces to open the list. However, selecting it will be a bit trickier. Selection is tight to mouse events. You might need to override them. If this is your intention, you can look on previous posts related to overriding mouse events with controlP5 and see if you can find something that could use and try in your case.

```auto
articoloCliente = listFileNames(pathDataSet + slash + clienti[clienteSelezionato]); // read a list of Files
cp5.get(ScrollableList.class, "ARTICOLI").setLabel("ARTICOLI"); // reset the top label
cp5.get(ScrollableList.class, "ARTICOLI").setItems(articoloCliente); // change present list with
cp5.get(ScrollableList.class, "ARTICOLI").open(); // force open
```

```auto
.setValue(1)
.open()
```
Solved! this solution works, but it should not be used inside of eventHandler because rise nullPointer exception.
Thanks kfrajer!
