Hello,

is there a command to shutdown the fltk-application?

the user should push the end-button and the application shutdown.

thx for your help

Yes, there is a C++ function that does that:
Place in in the callback function of the button and it will shutdown
you application. "status" is meant to carry error codes, but I usually
just use 0.

In fluid, the easiest way would be to place the command directly in the "callback-box" in the context menu of the button without defining an
extra callback function.
