ComboBox sort

[Tapani (Tapani Vaulasto)]

Hei
I have this set of ComboBox:

final ComboBox combos = new ComboBox[comboId.length]
;

A ComboBox gets name:

combos[i]
= new ComboBox(comboId[i]
);

ComboBoxes are populated from a JSONArray:

for (int i = 0; i < jArray.length(); i++) {
jObject = jArray.getJSONObject(i);
for (int ic = 0; ic < comboId.length; ic++) {
if (!jObject.isNull(comboId[ic]
)) {
arvoS = jObject.get(comboId[ic]
).toString();
combos[ic]
.addItem(arvoS);
continue;
}
}
}

Question:
Items of four ComboBoxes should be sort.
How to sort Items of a ComboBox to descending order?
An example:

combos[2]
[1909, 1914, 1922, 1923, 1926, 1927, 1928, 1929, 1930, 1931, . . . 2007, 2008, 2009, 2010]

Hi, Tapani!

ComboBoxes have IndexedContainers by default, so you could add the items in the order you want them. IndexedContainer also happens to implement Container.Sortable, which means that you can use the sort() method in
IndexedContainer
. (scroll down for the documentation, I can’t link directly to it since this forum software doesn’t accept ] in URL:s).

HTH,
