網格中的GXT復選框

Question

當網格單元格中的復選框改變其狀態時，我需要更新商店：添加或從商店中刪除值。 如何處理這個事件？ 順便說一句，我用這種方式在網格中創建了一個復選框：

column = new ColumnConfig();
column.setId("accepted");
column.setHeader("Accepted");
column.setWidth(55);

UPD2：現在我執行以下操作：首先創建復選框：

CheckColumnConfig checkColumn = new CheckColumnConfig("accepted", "", 55);
CellEditor checkBoxEditor = new CellEditor(new CheckBox());        
checkBoxEditor.setToolTip("If you click here server will consider this rule checking your messages");
checkColumn.setEditor(checkBoxEditor);
checkColumn.setHeader("apply");
configs.add(checkColumn);

比如下處理網格中的事件： UPD3：

grid.addListener(Events.CellMouseUp, new Listener<GridEvent>() {
            @Override
            public void handleEvent(GridEvent be) {
                PropertyItem item;
                    if (grid.getStore().getAt(be.getRowIndex()).isAccepted()){
                        item = new PropertyItem(val1, val2, val3, true);
                    } else {
                        item = new PropertyItem(val1, val2, val3, false);
                    }
                    store.update(item);
                    store.commitChanges();
                    saveProperties(store, customerId, toRemove);
            }
        });

這是正確的方法。

根據此處找到的文檔，您可以向CellEditor的Complete事件添加偵聽器。 在Complete事件Listener ，執行您需要完成的任何活動。

更新 ：嘗試以下操作

column.setRenderer(new GridCellRenderer() {

    @Override
    public Object render(ModelData model, String property, ColumnData config, int rowIndex, int colIndex, final ListStore store, Grid grid) {
        CheckBox box = new CheckBox();
        box.addListener(Events.Change, new Listener<FieldEvent>() {
             @Override
             public void handleEvent(FieldEvent be) {
                 st.commitChanges();
                 saveProperties(st, customerId, toRemove);

                // I'm not sure what saveProperties is, but see if this works now.
                // this event should DEFINITELY be fired when the checkbox is clicked
                // so if it doesn't work, try changing how you do your code here
                // maybe by doing model.set(property, (Boolean) be.getValue()); or something
             }
        });
        return box;
    }
});
