Hi there.
I'm trying to implement the treeCell Widget in my project, but i'm
having an issue since days now...
The SElectionModel is not firing for my root nodes for some reason. It
get fired thougth for leaf nodes.
Here is my node info code.
@Override
public <T> NodeInfo<?> getNodeInfo(T value) {
if (value == null) {
// LEVEL 0.
// We passed null as the root value. Return the
composers.
// Create a data provider that contains the
list of composers.
rootDataProvider = new
ListDataProvider<PartnerDTO>(partners);
// Create a cell to display a composer.
Cell<PartnerDTO> cell = new
AbstractCell<PartnerDTO>() {
@Override
public void render(Context context,
PartnerDTO value,
SafeHtmlBuilder sb) {
if (value != null) {
sb.appendEscaped(value.getCompanyName());
}
}
};
IconCellDecorator<PartnerDTO> decorator = new
IconCellDecorator<PartnerDTO>(
ICONS.partner_icon(), cell);
// Return a node info that pairs the data
provider and the cell.
return new
DefaultNodeInfo<PartnerDTO>(rootDataProvider,
decorator, selectionModelLeaf,
null, null);
} else if (value instanceof PartnerDTO) {
PartnerDTO dto = (PartnerDTO) value;
// LEVEL 2 - LEAF.
// We want the children of the playlist. Return
the songs.
ListDataProvider<ClientDetailsDTO> dataProvider
=
providerForPartners
.get(dto.getPartnerID());
if (dataProvider == null) {
dataProvider = new
ListDataProvider<ClientDetailsDTO>();
providerForPartners.put(dto.getPartnerID(), dataProvider);
fetchClients(dto.getPartnerID());
}
// Create a cell to display a composer.
Cell<ClientDetailsDTO> cell = new
AbstractCell<ClientDetailsDTO>()
{
@Override
public void render(Context context,
ClientDetailsDTO value,
SafeHtmlBuilder sb) {
if (value != null) {
sb.appendEscaped(value.getDisplayName() + " ("
+
value.getNumberOfApp() + ")");
}
}
};
IconCellDecorator<ClientDetailsDTO> decorator =
new
IconCellDecorator<ClientDetailsDTO>(
ICONS.client_icon(), cell);
// Use the shared selection model.
DefaultNodeInfo<ClientDetailsDTO> info = new
DefaultNodeInfo<ClientDetailsDTO>(
dataProvider, decorator,
selectionModelLeaf, null);
return info;
}
return null;
}
