估计你得容器选择错了。

或者设置为透明的，你可以在属性框找到它，然后在看窗体上的具体位置是怎么回事
还有bringtofront等

看不见的原因应该是被其它的控件盖住了

在Object TreeView里面把它拖到你要放到的容器里面去

自己加一个不就得了，再修改属性！

何苦呢，你直接在你的容器里面新建一个SpeedButton就可以了啊，参照原来的样式修改一下属性，几分钟就搞定了。
你的容器是不是标准控件？如果是的话用上述方式应该就可以解决了，如果是第三方控件而用上面的方法又解决不了的话，那应该就是那个控件的问题。我以前也遇到过类似的问题，后来我就弃用了那个控件。

看看在属性编辑器中的，combobox中有没有？有的话，说明被别的覆盖了

因为是复制的,所以其他属性应该都是对的
transparent是true

石头兄说得 bringtofront是什么,在哪里看?

我也估计是容器的问题,但是我拖不到我想让他进去的容器里面去.不知道为什么.
我找到容器的代码行,直接照葫芦定义,又报错说这个object未定义
