Java 如何在GWT中将带有clickHandler的锚点添加到ListGridRecord

我需要将带有clickHandler的锚添加到ListGridRecord。单击以定位应调用函数（向ListGrid添加更多行）。我能够使用href编写锚定：

private void addAnchorToRecord(ListGridRecord rec) {
    String img  = "<img src='pict/Plus.png'/>";
    Anchor myAnchor = new Anchor(img, true, "example.html");
    String value = myAnchor.toString();
    rec.setAttribute("versions", value);
}

然后在我的牢房里只有“[对象]”

我需要的功能：将属性设置为ListGridRecord，它具有图标和clickHandler。

如果您只需在ListGridRecord中添加一个按钮，然后将clickHandler添加到该按钮，则会更容易。必须这样做：

 @Override
 protected Canvas createRecordComponent(final ListGridRecord record, final Integer colNum){
        if(getFieldName(colNum).equalsIgnoreCase(("btnFieldName"))){
               IButton btn= new IButton("");
               //configure the button
               btn.addClickHandler(new ClickHandler() {
                  @Override
                  public void onClick(ClickEvent event) {
                    //your logic
                  }
               });
               return btn;
         }
     return super.createRecordComponent(record, colNum);
 }

配置ListGrid时：

    setShowRecordComponents      (true );
    setShowRecordComponentsByCell(true );

设置字段时

    ...
    ListGridField btnField= new ListGridField("btnFieldName", " ");
    ...

然后像这样覆盖createRecordComponent：

 @Override
 protected Canvas createRecordComponent(final ListGridRecord record, final Integer colNum){
        if(getFieldName(colNum).equalsIgnoreCase(("btnFieldName"))){
               IButton btn= new IButton("");
               //configure the button
               btn.addClickHandler(new ClickHandler() {
                  @Override
                  public void onClick(ClickEvent event) {
                    //your logic
                  }
               });
               return btn;
         }
     return super.createRecordComponent(record, colNum);
 }

有没有理由使用GWT锚定而不是SmartGWT？另外，请检查，，无原因。我已编辑了我的问题。您是否检查了我发布的SmartGWT showcase链接？您可能正在尝试这样做。我想在ListGridRecord中设置所有内容，而不是在ListGridField中。这是我的错误。谢谢

    ...
    ListGridField btnField= new ListGridField("btnFieldName", " ");
    ...

 @Override
 protected Canvas createRecordComponent(final ListGridRecord record, final Integer colNum){
        if(getFieldName(colNum).equalsIgnoreCase(("btnFieldName"))){
               IButton btn= new IButton("");
               //configure the button
               btn.addClickHandler(new ClickHandler() {
                  @Override
                  public void onClick(ClickEvent event) {
                    //your logic
                  }
               });
               return btn;
         }
     return super.createRecordComponent(record, colNum);
 }
