Okay, I used the Timeline and got what I was after. I need to streamline it
a little (I'll probably not use the marker_name in the end, but it is nice
to know how it works) ...
[...
timeline = new Timeline(250);
timeline.add_marker_at_time("one",1);
timeline.add_marker_at_time("two",50);
timeline.add_marker_at_time("three",100);
timeline.add_marker_at_time("four",150);
timeline.add_marker_at_time("five",200);
timeline.add_marker_at_time("six",250);
timeline.marker_reached.connect(marker_reached);
timeline.start();
...]
private void marker_reached(string marker_name) {
stdout.printf("%s", marker_name);
if (marker_name == "one") {
item.set_opacity(0);
}else if (marker_name == "two") {
item.set_opacity(255);
}else if (marker_name == "three") {
item.set_opacity(0);
}else if (marker_name == "four") {
item.set_opacity(255);
}else if (marker_name == "five") {
item.set_opacity(0);
}else if (marker_name == "six") {
item.set_opacity(255);
}
}
Thanks for your help.
