Adding selection listener to GXT Grid?
提问by thedude19
I'm trying to add a selection listener to my GXT (Ext GWT) Grid, but I can't seem to get it to fire. I've tried many variations of this with no luck:
我正在尝试向我的 GXT (Ext GWT) 网格添加一个选择侦听器，但我似乎无法启动它。我已经尝试了很多变体，但都没有运气：
myGrid.addListener(Events.Select, new SelectionListener<ComponentEvent>() {
@Override
public void componentSelected(ComponentEvent ce) {
System.out.println("selected");
}
});

myGrid.getSelectionModel().addSelectionChangedListener(new SelectionChangedListener<ModelData>() {
@Override
public void selectionChanged(SelectionChangedEvent<ModelData> se) {
...
}
});

将此答案升级到 GXT v3
grid.getSelectionModel().addSelectionChangedHandler(
new SelectionChangedHandler<ModelData>(){
@Override
public void onSelectionChanged(SelectionChangedEvent<ModelData> event) {
}
});

Try:
尝试：
myGrid.addListener(Events.Select, new Listener<GridEvent<ModelData>>() {
@Override public void handleEvent(GridEvent<ModelData> be) {
System.out.println("selected");
}
});
Replacing ModelData with your model type if necessary.
如有必要，用您的模型类型替换 ModelData。

Seemed to have found a workaround for this:
似乎找到了解决方法：
myGrid.addListener(Events.OnClick, new Listener<ComponentEvent>() {
@Override
public void handleEvent(ComponentEvent ce) {
// Handle the grid event
}
});
Seems like you just have to be generic about it, then you can check and cast your ComponentEvent to a GridEvent.
似乎你只需要对它通用，然后你就可以检查你的 ComponentEvent 并将其转换为 GridEvent。

Do you use GXT 2.x version ? Did you check whether required events are sinked? for example like grid.sinkEvents(Event.ONCLICK | Event.ONDBLCLICK | Event.MOUSEEVENTS);
你使用 GXT 2.x 版本吗？您是否检查了所需的事件是否已沉没？例如像 grid.sinkEvents(Event.ONCLICK | Event.ONDBLCLICK | Event.MOUSEEVENTS);
