问题描述

我要显示一个半透明始终位于顶层的窗口有一些信息，但我不希望这个窗口把输入或接收焦点。所有的鼠标点击应该去underlaying的窗口。

I want to display an semi-transparent always-on-top window with some information, but I do not want this window to take input or receive focus. All mouse-clicks should go to the underlaying window.

我记得在shell更换使用年限见状回来，但我不记得女巫。

I remember seeing this in a shell-replacement application years back, but I can't remeber witch.

任何想法如何实现与Delphi或C＃

Any Ideas how to achieve this effect with delphi or c#?

更新这样的效果：

我不能完全得到所提出的解决方案，德尔福工作。返回HTTRANSPARENT为NCHITTEST消息将停止所有mousemessages达到了形式，但它希望它向下传递到z顺序下一个窗口。这是方法换货跨进程工作，或者只彪在spesific窗口childelements？

I can't quite get the proposed solution to work with delphi. Returning HTTRANSPARENT for the NCHITTEST-message will stop all mousemessages reaching the form, but it want pass it down to the next window in z-order. Is this method ment to work across processes, or is it only ment to work on childelements of a spesific window?

如果我设置扩展风格标志WS_EX_TRANSPARENT，不过，所有的鼠标点击工作将穿越到下一个窗口，但我不会让NCHITTEST消息可言的，将无法控制那里的窗户应该是点击率或不...

If I set the ExStyle flag WS_EX_TRANSPARENT, though, all mouseclicks will travel through into the next window, but I will not get the NCHITTEST-message at all, and will not be able to control where the windows should be click-through or not...
