I am working on a timer which should after a certain time show a popup window. I want to force the user to accept the fact that the time is up.
我正在研究一个计时器，它应该在一定时间后显示一个弹出窗口。我想强迫用户接受时间到了这个事实。
I would like to set the window to be visible on all workspaces. I am able to set that property manually in a window manager but the application should do that.
我想将窗口设置为在所有工作区上都可见。我能够在窗口管理器中手动设置该属性，但应用程序应该这样做。
How to ask a window manager to make a window "show on all workspaces"?
如何让窗口管理器创建一个“在所有工作区上显示”的窗口？
