程序化构建的窗口始终位于顶部
在我的源代码中，我启动了一个新的工具窗口并纯粹在C＃中生成它。这是我的窗口构造和事件处理程序代码。

如果我放置＆＃34;工具＆＃34;窗口为＆＃34; TopMost＆＃34;。它适用于我的MainWindow，以及我打开的每个其他窗口。
另一方面，如果我不把它作为＆＃34; TopMost＆＃34;它隐藏在MainWindow的后面。
但我需要的是工具窗口只能在MainWindow的顶部显示。我怎么能做到这一点？

答案 0 :(得分：1)
我看不到您为工具窗口设置Owner的位置。
将Tools.Owner设置为父表单，应该允许您跳过TopMost的集合，以便它不会出现在非应用程序窗口上，也允许它保留在父表单上。
