我是 GWT 的新手。我有一个网格,其中包含从 BaseModel 映射的简单数据。当用户选择一行时,它应该被选中。我检查了一些示例并发布,看来我们做得正确。下面的代码来创建网格。
您能否提及将阻止此选择的情景?
List<BaseModel> gridData= new ArrayList<BaseModel>();
List<ColumnConfig> config = new ArrayList<ColumnConfig>();
config.add(new ColumnConfig("isPrimary","Primary",70));
config.add(new ColumnConfig("accountName","Account Name",320));
config.add(new ColumnConfig("activeProgram","Active Program",150));
config.add(new ColumnConfig("accountNumber","Account",100));
config.add(new ColumnConfig("accountXref","Account Xref",150));
config.add(new ColumnConfig("status","Status",93));
ColumnModel cm = new ColumnModel(config);
PagingModelMemoryProxy proxy = new PagingModelMemoryProxy(gridData);
final PagingLoader<PagingLoadResult<Data>> loader = new BasePagingLoader<PagingLoadResult<Data>>(proxy);
loader.setRemoteSort(false);
store = new GroupingStore<Data>(loader);
final PagingToolBar toolBar = new PagingToolBar(10);
toolBar.bind(loader);
loader.load(0, 10);
GroupingView view = new GroupingView();
view.setShowGroupedColumn(true);
view.setForceFit(true);
view.setGroupRenderer(new GridGroupRenderer() {
public String render(GroupColumnData data) {
String l = data.models.size() == 1 ? "Item" : "Items";
return data.group.substring(data.group.indexOf("|") + 1, data.group.length())
+ " (" + data.models.size() + " " + l + ")";
}
});
ContentPanel cp = new ContentPanel();
cp.setBodyBorder(false);
cp.setButtonAlign(HorizontalAlignment.CENTER);
cp.setLayout(new FitLayout());
cp.setFrame(true);
cp.setSize(verticalPanelWidth, "300px");
cp.setBorders(hidden);
cp.setBottomComponent(toolBar);
GWT.log("store size" + store.getCount());
grid = new Grid<Data>(store,cm);
final GridSelectionModel<Data> sm = grid.getSelectionModel();
sm.setSelectionMode(SelectionMode.SINGLE);
grid.setSelectionModel(sm);
final CellSelectionModel<Data> csm = new CellSelectionModel<Data>();
csm.bindGrid(grid);
grid.setBorders(true);
grid.ensureDebugId("gridDebugId");
//grid.ensureDebugId("gridDebugId");
grid.setTabIndex(5);
cp.add(grid);
return cp;
