T - the element type in the ComboBox.public class ComboBoxSearchable<T> extends Searchable<T>
ComboBoxSearchable is an concrete implementation of Searchable that enables the search function
on non-editable ComboBox. It's very simple to use it. Assuming you have a ComboBox, all you need to do is to call
ComboBox comboBox = ....;
ComboBoxSearchable searchable = new ComboBoxSearchable(comboBox);
There is very little customization you need to do to ComboBoxSearchable. The only thing you might need is when the element in the ComboBox needs a special conversion to convert to string. If so, you can override convertElementToString() to provide you own algorithm to do the conversion.
ComboBox comboBox = ....;
ComboBoxSearchable searchable = new ComboBoxSearchable(comboBox) {
protected String convertElementToString(Object object) {
...
}
};

SearchableHere are some examples. In the case of ListView, the index is the row index. In the case of TreeView, the index is the row index too. In the case of TableView, depending on the selection mode, the index could be row index (in row selection mode), or could be the cell index (in cell selection mode).
