问题 I am writing a (very) small application which just performs some minor things at start and should write a message on the screen similar as for an on-screen-display: Big letters, without any window, above everything, visible for some moment and then fade away. If possible I do not want to create a window for it. What is the right way to do this?

I've been able to get it to work by calling it on one of my buttons which is always present in the view, but this feels wrong - and I'm sure there must be a way to get around this.
