Those who know me know that i am not a GUI/click/point kind of person
but i am kinda required to create a user interface.  First attempt is
using FLTK widgets

I have managed to create a panel with three sliders and three buttons
(quite amazing for me!) and can even use the sliders for amplitude etc

My problem is how to implement a reset; I would like it to set the
values for the sliders to a sane value.  current code looks like

gk1, gih1 FLslider   "Sl1", 0, 32000, 0, 5, -1, 300,15, 20,50
gk2, gih2 FLslider   "Sl2",  0, 1,     0,  5, -1, 300,15, 20,100
gk3, gih3 FLslider   "Sl3",   0, 100,    0,  5, -1, 300,15, 20,150
gkr, ihb3 FLbutton "@<<", 1, 0, 1, 50, 15, 150, 200, -1
.....

  FLsetVal  gkr, 10000, gih1
  FLsetVal  gkr, 0, gih2
  FLsetVal  gkr, 0, gih3
  kcps      =           cpspch(p4)
....

If click on the button the values reset, but the sliders cease to
function.  Surely the FLsetVal should trigger and reset?  What have I
failed to understand?

Iain,

Thanks for explaining it better to him. That is exactly the idea I was
going for, but a lot of times I expect people to think exactly like
me.
