使用VB.NET的菜单区域中的透明标签 [英] Transparent Label in Menu area with VB.NET

问题描述

我已经阅读了许多有关如何创建透明标签的文章，但在我看来，我的特殊情况并未涵盖.很简单，我在表单的右上角放置了一个标签，它实际上是菜单条的一部分.标签向用户显示一些信息，但我希望它是透明的.香港专业教育学院尝试了各种方法，包括

I've read many articles on how to create transparent labels but it seems to me that my particular case is not covered. Very simply I have a label placed in the upper right part of the form, which in fact is part of the menu strip. The label displays some info to the user but I wish it were transparent. Ive tried various methods including

lblAct.Parent = mnuMain '(or Me)
lblAct.BackColor = Color.Transparent
lblAct.BringToFront()

但是无法正常工作.有人对我如何使该职位的职位透明化提出建议吗?

but cant get it to work. Anyone have suggestions on how I can make that lable in that position transparent?

谢谢

推荐答案

是的，您无法完成这项工作.这是Windows的限制，透明效果是相对于顶层窗口的，堆叠效果不起作用.您将看到表单作为背景，而不是菜单栏.从技术上讲，可以破解要求菜单条自己渲染以创建背景的标签.但是，当条重新绘制自身时，Windows不会生成绘制消息.例如，当用户调整窗体的大小时，这将是显而易见的.

Yes, you can't make this work. It's a Windows restriction, transparency effects are relative to the top-level window, stacking effects do not work. You'll see the form as the background, not the menu strip. Hacking a label that asks the menustrip to render itself to create the background is technically possible. But Windows won't generate a paint message when the strip repaints itself. Which will be starkly visible when the user resizes the form for example.
