Navigate into Listbox zk with radio component - listbox

Question

I have this Listboxin ZUL page :
<listbox id="lstboxResult">
<listhead sizable="true">
<listheader label="Editore" />
<listheader id="lstAzienda" />
</listhead>
</listbox>
And a ListitemRender :
public void render(Listitem listitem, Object data, int index) throws Exception {
final String o = (String) data;
if (!o.equals("")) {
addListcell(listitem, String.valueOf(o));
addRadiogroup(listitem);
}
}
private void addListcell(Listitem listitem, String value) {
Listcell lc = new Listcell();
Label lb = new Label(value);
lb.setParent(lc);
lc.setParent(listitem);
}
private void addRadiogroup(Listitem listitem) {
Radio radAla = new Radio("Label1");
Radio radPeg = new Radio("Label2");
Radio radRw = new Radio("Label3");
Radiogroup rg = new Radiogroup();
radAla.setRadiogroup(rg);
radPeg.setRadiogroup(rg);
radRw.setRadiogroup(rg);
radAla.setParent(rg);
radPeg.setParent(rg);
radRw.setParent(rg);
Listcell lc = new Listcell();
rg.setParent(lc);
lc.setParent(listitem);
}
How can get data from listbox setting Label value in list cell and checked value?
The second column contains 3 radios and each represent a choice. I'd like to save these choices in the database. I need a POJO to save the label and the checkbox choice for each row.

Answer 1

You can achieve this by using a small object in your list model instead of String. When the radios are checked, you save the choice in that object. Then you can save it later.
Look at this example:
lstboxResult.setModel(new ListModelList<>(Arrays.asList(new MyObject("1"), new MyObject("2"))));
lstboxResult.setItemRenderer(new ListitemRenderer<MyObject>()
{
#Override
public void render(Listitem listitem, MyObject data, int index)
throws Exception
{
Listcell lc = new Listcell(value);
lc.setParent(listitem);
Radio radAla = new Radio("Label1");
Radio radPeg = new Radio("Label2");
Radio radRw = new Radio("Label3");
Radiogroup rg = new Radiogroup();
radAla.setRadiogroup(rg);
radPeg.setRadiogroup(rg);
radRw.setRadiogroup(rg);
radAla.setParent(rg);
radPeg.setParent(rg);
radRw.setParent(rg);
Listcell lc = new Listcell();
rg.setParent(lc);
lc.setParent(listitem);
rg.addEventListener(Events.ON_CHECK, e -> {
data.setSelectedIndex(rg.getSelectedIndex());
data.setSelectedLabel(rg.getSelectedItem() != null ? rg.getSelectedItem().getLabel() : null);
System.out.println(data.getLabel() + " " + data.getSelectedIndex() + " " + data.getSelectedLabel());
});
}
});
private static class MyObject
{
private String label;
private int selectedIndex = -1;
private String selectedLabel;
public MyObject(String label) { this.label = label; }
public String getLabel() { return label; }
public int getSelectedIndex() { return selectedIndex; }
public void setSelectedIndex(int selectedIndex) { this.selectedIndex = selectedIndex; }
public String getSelectedLabel() { return selectedLabel; }
public void setSelectedLabel(String selectedLabel) { this.selectedLabel = selectedLabel; }
}
Now you can use the model to read the chosen radios from the MyObjects and do whatever you want with them.
