[gcompris-devel] howto implement a timer?

[bruno]

Sound great, it brings an interresting new feature, we have not
investigated this even if some board would be better with this.

I suggest to use the repeat icon spot that we already have in the
toolbar for audio boards, to implement the "please help me" function.
gcompris_bar_set(GCOMPRIS_BAR_LEVEL|GCOMPRIS_BAR_OK|GCOMPRIS_BAR_REPEAT)
then implement a repeat callback
I assume there is no need to have a repeat icon and a "please help".
For now, if you need a button, you can use repeat like described here.
