推荐答案

签出此页面.另外，带有区域和抗锯齿边缘的透明按钮" 可能是您可能也可能不是"重新寻找，已经建成. 创建透明按钮的简便方法" 是另一个示例，但显然存在内存泄漏，并且没有.移动控件时不要重绘(也许您可以通过阅读上面的背景更新时重绘的文章来解决此问题).

Check out this article, which has a solution for making transparent controls that can be redrawn when the background changes (if you are layering your buttons over video, this could be useful). Sounds like you already know how to make owner drawn buttons, but just in case you don''t, read this page. Also, "Transparent Button with Region and Anti-Aliased Edges" may or may not be what you''re looking for, already built. "An easy way to create transparent button" is another example, but it apparently has memory leaks and doesn''t redraw when the control is moved (maybe you can fix that up by reading the above article that redraws when the background is updated).
