Introduce stopOnCtrlC in application. #816

Closed gizahNL closed 1 year ago

gizahNL commented 1 year ago

This allows consuming applications signal that they intend to keep running when control+c is pressed, and instead want the event to be handled by their primitives.

My use case is for a window in which I run shell commands; And that I want to cancel via pressing control+c. The current default of stopping on control+c is kept so there should not be any surprises for anyone updating.

This is what Application.SetInputCapture() is for. This specific use case is actually documented there. You can also use it to bind "Close Application" to a different key.

Can you perchance explain how to do it that way? I am able to block handling of control+c that way completely, but I don't see a way to let control+c be passed down chain without the application getting stopped.

Actually, your question made me realize that there was indeed no way to forward Ctrl-C to primites. You were able to block it or translate it but not forward.

I fixed this now. There is now a specific way to achieve this. Check out the link above for details.

Many thanks! That will work for me !
