I was attempting to make a "tab blinker" wth this code here:
for(var/i=5;i>0;i--)
winset(src,"help_pane","background-color=#[!(i%2) ? "000000" : "ff0000"]")
sleep(10)
To draw attention to the Help tab when new information is displayed in it, but it seems background-color just changes the interior background colour of the tab content.
If not, how difficult would it be to make the background-color of each pane's physical tab a property of the pane and not the tab control? I think it'd be rather useful.
