The problem is that the Toggle Button Callback does not stop the execution of the loop because the flag is never checked.
What you want to do is have the togglebutton callback throw away 'off' calls and 'enable' 'on' calls but have enabled check on each iteration if it's still on. The English on this isn't very clear I know! so here is the pseudocode
function tglbutton_callback(blha,blah)
if 'off'
return
end
while get(hObject,'value')
%check on each loop iteration if it's on
do_stuff
end

Consider this example function:
function example_togglin
hF = figure;
hTb = uitoolbar(hF);
hTg = uitoggletool('oncallback',@cb,'parent',hTb,'cdata',repmat(magic(16)./16^2,[1 1 3]));
function cb(src,evt)
cnt = 0;
while strcmp(get(src,'State'),'on') && cnt<20
cnt = cnt+1;
disp(['I''m on!!! Iteration: ' num2str(cnt)])
pause(0.25);
end
Save this as example_togglin.m and run it.
