Question

尽可能尝试，当我将按钮放在spark dataGrid中时，我无法设置Spark按钮。我被限制使用光环主题。

我在单独的mxml文件中创建了按钮渲染器;我在dataGrid外面有单独的按钮，正确显示皮肤，所以我确信皮肤没有任何问题。这一点的重点是在dataGrid中使用与外部相同的皮肤

以下代码显示了我所看到的相同行为;在这种情况下，渲染器是在线创建的。似乎skinClass不受尊重。还是有另一种方法可以做到。

<s:DataGrid id="dg" width="500" dataProvider="{employees2}">
    <s:columns>
        <s:ArrayList>
            <s:GridColumn dataField="name" headerText="Name">
                <s:itemRenderer>
                    <fx:Component>
                        <s:GridItemRenderer>
                            <s:Button label="Press Me"
                                      top="0" bottom="0" left="0" right="0"
                                      skinClass="MyButtonSkin" />
                        </s:GridItemRenderer>
                    </fx:Component>
                </s:itemRenderer>
            </GridColumn>   
        </s:ArrayList>
    </s:columns>
</s:DataGrid>

Answer 1

似乎将按钮缩放到网格项的大小不会调整角半径。

我最终得到一个200x200像素的按钮，角半径为6像素;它只是无法看到。我将值提高到25，现在我可以看到它

带有按钮和皮肤的Flex DataGrid
