WPF设置所有者窗口不起作用

Question

I have a main Window that I want it to be the owner of all other windows

from the class of the main window this was the code

private voide btn_Click()
 {
      SomeWindow w = new SomeWindow()
      w.Owner = this;
      w.Show();
  }

also tried

w.Owner = Application.Current.MainWindow

but it never works

Answer 1

According to your comment, it seems that you want something like this:

 w.ShowInTaskbar = false;

or you might want to do:

w.ShowDialog();

Note what Owner-Child relationships do :

Once this relationship is established, the following behaviors are exhibited:

• If an owner window is minimized, all its owned windows are minimized as well.

• If an owned window is minimized, its owner is not minimized.

• If an owner window is maximized, both the owner window and its owned windows are restored.

• An owner window can never cover an owned window.

• Owned windows that were not opened using ShowDialog are not modal. The user can still interact with the owner window.

• If you close an owner window, its owned windows are also closed.

• If an owned window was opened by its owner window using Show, and the owner window is closed, the owned window's Closing event is not raised.
