在 TOPMOST window 之后放置一个 window

Question

我有一个 window，它是 TOPMOST，我有另一个 (myWindow) window，我想放在第一个后面，我不想要第二个 window成为最重要的：

SetWindowPos(topMostWin, HWND_TOPMOST, left, top, width, height, flags);
LONG_PTR exstyle = ::GetWindowLongPtr(myWindow, GWL_EXSTYLE);
if (exstyle & WS_EX_TOPMOST)
{
    exstyle &= ~WS_EX_TOPMOST;
    if( ! ::SetWindowLongPtr(myWindow, GWL_EXSTYLE, exstyle))
    {
        LOG_ERROR();
    }
}
SetWindowPos(myWindow, topMostWin, left, top, width, height, flags);

但是 myWindow 一直表现得像最顶层 window，当我检查 myWindow 的 WS_EX_TOPMOST 属性扩展样式时，它仍然处于打开状态。即使我将 window 放在最顶层 window 之后，是否可以关闭最顶层位？

Answer 1

HWND_TOP 会将您的 window 置于 z-order 的顶部，位于任何最顶部的 windows 之后。

Answer 2

As a result of the introduction of “topmost” windows, HWND_TOP now brings the window “as high in the Z-order as possible without violating the rule that topmost windows always appear above non-topmost windows”. What does this mean in practice?

If a window is topmost, then HWND_TOP puts it at the very top of the Z-order.

If a window is not topmost, then HWND_TOP puts it at the top of all non-topmost windows (i.e., just below the lowest topmost window, if any).

Note: The above discussion completely ignores the issue of owner and owned windows. I left them out because they would add a layer of complication that distracts from the main topic.
