How to use GuiTrigger::Down() in libwiigui

I am having some truobles trying to use the GuiTrigger::Down() function. I can't find an app that uses it to use as an example.

BTW its in libwiigui

Take a look at gui_filebrowser.cpp

would this be the correct method:

if(trigDown->Down())
		{
		//code to be executed here
		}

Honestly, i just cant seem to figure out how the Down function is used, all i want to do is reposition some text when a button is pressed but i dont know how id deal with several triggers for one element
