Hi everybody.
Is it possible to select a single Listcell in a listbox?
Normally you see the entire row selected when you move the mouse over a listcell...
I solved with a java-generated grid, like this :
Columns aGridColumns = new Columns();
aGridColumns.setId(cGridModuleViewColumnsName);
for (int aCurrentColumn = 0;aCurrentColumn<_module.getColumnsnumber();aCurrentColumn++)
aGridColumns.appendChild(new Column(String.valueOf(aCurrentColumn), cGridModuleViewColumnsName));
aGridColumns.setParent(this.getFellow(cGridModuleViewName));
Cell[] aCells = aCellsCollection.toArray(new Cell[0]);
Rows aRows = new Rows();
for (int aCurrentRow=_module.getRowsnumber() * 2-1;aCurrentRow>=0;aCurrentRow--) {
Row aRow = new Row();
for (int aCurrentColumn = 0;aCurrentColumn<_module.getColumnsnumber();aCurrentColumn++) {
final Cell aCurrentCell = aCells[aCurrentRow * _module.getColumnsnumber() + aCurrentColumn];
Button aButton = new Button((aCurrentCell.getContentid() == null ? " " : aCurrentCell.getContentid()));
aRow.appendChild(aButton);
}
aRows.appendChild(aRow);
}
this.getFellow(cGridModuleViewName).appendChild(aRows);I placed a button inside : that's not so nice but it works.
Thanks to everybody.

You can try grid component, to have an individual cell selection in a row.
Unfortunately ZK Spreadsheet offers a way to embed only an existing xls file into a web page.
But i don't need that.
Thank you so much! I'll try it.
Maybe you can use ZK Spreadsheet (http://www.zkoss.org/product/zkspreadsheet.dsp)
Thanks, but i was wondering if there is the possibility to select a single cell
in a row with the mouse because when i move in a cell of my listbox the entire
row becomes highlighted.
Your code appears to set "onDoubleClicked" event.
But i wish to display a listbox as a grid with every single cell highlighted (like excel).
Thanks anyway
Think in objects!
What you get as a row from the listBox represents in most cases an object from the
underlaying Data.
--> the single ListCell represents a property of the domain object.
@SuppressWarnings("unchecked")
public void onDoubleClicked(Event event) throws Exception {
// get the selected customer object from the listbox
Listitem item = customerListbox.getSelectedItem();
if (item != null) {
// Cast to the represented Domain Object
Customer customer = (Customer) item.getAttribute("data");
...
}
public class CustomerItemRenderer implements ListitemRenderer, Serializable {
private static final long serialVersionUID = 1L;
private transient final static Logger logger = Logger.getLogger(CustomerItemRenderer.class);
@Override
public void render(Listitem item, Object data) throws Exception {
Customer customer = (Customer) data;
Listcell lc = new Listcell(customer.getCustomerName());
lc.setParent(item);
lc = new Listcell(customer.getCustomerNr());
lc.setParent(item);
item.setAttribute("data", data);
// ComponentsCtrl.applyForward(item, "onClick=onClicked");
ComponentsCtrl.applyForward(item, "onDoubleClick=onDoubleClicked");
}
}
regards
Stephan
