Depending on what you want to do, some have to be interruptible, and
some have to prioritary. For example in the following example, where you
can start/stop incrementing a slider, the "start" callback must be
interruptible but the "stop" callback must be prioritary :
function stop() set("button","userdata",%t) endfunction function start()
try but = get("button") but.string="stop" but.callback="stop()"
but.callback_type=10; but.userdata = %f; sl = get("slider"); for
t=tuser(tuser>=sl.value) if but.userdata break; end sl.value = t;
title(msprintf("t=%g",t)) end but.callback_type=0;
but.callback="start()" but.string="start" catch end endfunction
tuser=0:0.001:1; sl=uicontrol("style","slider",... "tag","slider",...
"units","normalized",... "position",[0.1 0 0.9 0.05],... "background",[1
1 1],... "min",t(1),"max",t($),"sliderstep",(t(2)-t(1))*[1 1]);
but=uicontrol("style","pushbutton",... "units","normalized",...
"position",[0 0 0.1 0.05],... "string","start",... "tag","button",...
"string","start",... "callback","start()")
