This looks like it would get a bit tricky if every component in your view handled the same mouse event. Ie, if the user drags item 1 item 2 would process those events as well? If I understand correctly, you are looking to have this and this.
Parent and this.parent. Parent handle mouse actions on this . In that case the recursion would be up, and not down.
Based on your scenario I have a suggestion for the keyboard side of things.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
