使窗口对WindowFromPoint透明，也可能对EnumWindows透明吗? [英] Make window transparent to WindowFromPoint, and possibly EnumWindows also?

问题描述

是的，标题说明了一切.

原因是我的程序的最顶层窗口层行为干扰了chrome网页浏览器(以及可能的其他程序)的拖放目标行为，涉及剥离标签并将其拖放到chrome的其他实例上. > (我的程序是btw: http://sourceforge.net/projects/windowshades/ [

Yep, the title says it all.

The reason is that my programs topmost-window-layer-behavior interferes with the drop-target behavior of the chrome web browser (and likely other programs), with regards to peeling off tabs and dropping them on other instances of chrome.
(my program is this btw: http://sourceforge.net/projects/windowshades/[^], you see it''s violating windows-design-guidelines by staying topmost despite everything you can throw at it, which leads to the current problem which i''m trying to fix :P)

[My current way of dealing with this problem is i detect when a person is peeling off chrome-tabs and literally hide the overlay until the point when they release the mouse, and naturally i want to solve this problem correctly to prevent interference with other programs which i''m not aware of]

And right now i''m assuming that the solution will be to to make my program transparent to WindowFromPoint, and possibly other windows discovery methods like EnumWindows.
