我正在尝试在SmartGWT中设置ListGrid表对象的选定记录,但我找不到任何方法。我知道有一个getSelectedRecords()函数,但没有匹配的setSelectedRecords()。我试图看看set / getSelectedState()是否可行,但GWT抱怨需要主键和DataSource对象。有没有办法设置ListGrid的选择?

为此,您可以使用selectRecords()
方法之一,如下所示:
public void onModuleLoad()
{
VLayout main = new VLayout();
final ListGrid grid = new ListGrid();
grid.setHeight(500);
grid.setWidth(400);
grid.setFields(new ListGridField("name", "Name"));
grid.setData(createRecords());
final IButton button = new IButton("Select some");
button.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event)
{
grid.selectRecords(new int[]{2, 3}); //This will select index 2 and 3
}
});
main.addMember(grid);
main.addMember(button);
RootPanel.get().add(main);
}
private ListGridRecord[] createRecords()
{
return new ListGridRecord[]{
createRecord("monkey"),
createRecord("banana"),
createRecord("orange"),
createRecord("sun")
};
}
private ListGridRecord createRecord(String name)
{
ListGridRecord record = new ListGridRecord();
record.setAttribute("name", name);
return record;
}
