Best way to use button rollover/out?

[John J]

I want to have a label update it's text when the cursor is over a button.. kind of like a tool tip. I have it working just fine, but am wondering if there is a more efficient way to do it. Here is what I'm using now:

var SPtip:String = "Rehearse in single player mode";

BtnSP.addEventListener("rollOver", this, "UpdateSPTooltipOver");
BtnSP.addEventListener("rollOut", this, "UpdateSPTooltipOut");
BtnSP.focused = false;

function UpdateSPTooltipOver() {
	
	lblTooltip.text = SPtip;   
}

function UpdateSPTooltipOut() {
	
	lblTooltip.text = "";   
}

I'm just setting up vars with the needed strings then using them based on what button is rolled over. But it seems a bit inefficient to have rollover and rollout functions for every button doesn't it?

That's fine, but if you want to share the same rollOver and rollOut functions for all of the buttons, write your functions like so:

function UpdateTooltipOver(event:Object) {
    switch(event.target) {
        case(BtnSP):
	    lblTooltip.text = SPtip;
            break;
    }
}
