XLib：'软关闭'一个窗口(XLib: 'Soft-Closing' a window)

我知道，我可以通过调用“关闭”X11窗口：

XDestroyWindow(display, id);

问题是，这会立即破坏窗口。另一方面，如果我单击关闭按钮（标题栏中的x），应用程序可以显示“你真的要退出吗？”之类的内容。

那么我怎样才能模仿这种类型的窗口关闭？

背景：我正在关闭其他应用程序的窗口，而不是我自己的窗口

I know, that I can 'close' an X11 Window by calling:

XDestroyWindow(display, id);

The problem is, this destroyes the window immediately. On the other hand, if i click the close button (x in the title bar) the app can show something like "Do you really want to exit?".

So how can I emulate this type of window closing?

Background: I am closing windows from other applications, not my own

它可以与stackoverflow.com/questions/1157364/intercept-wm-delete-window-on-x11相同

I found a solution:

XEvent event; event.xclient.type = ClientMessage; event.xclient.window = id; event.xclient.message_type = XInternAtom(d, "WM_PROTOCOLS", TRUE); event.xclient.format = 32; event.xclient.data.l[0] = XInternAtom(d, "WM_DELETE_WINDOW", FALSE); event.xclient.data.l[1] = CurrentTime; XSendEvent(d, id, False, NoEventMask, &event);

Where d is the display handle and id is the window ID.
