ICS3U1 Unit 1 Activity 5: Question 2

// Date Completed: July 12, 2017
// Purpose: Calculating the possibility of forming a triangle when given three side lengths

// This line makes the button, btnRisk wait for a mouse click
// When the button is clicked, the determineSum function is called
btnDetermine.addEventListener(MouseEvent.CLICK, determineSum);

// This line makes the textinput, txtinLevel wait for a mouse click
// When a textinput is clicked, the clearLabel 1, 2, or 3 functions are called
txtinSideA.addEventListener(MouseEvent.CLICK, clearLabel1);
txtinSideB.addEventListener(MouseEvent.CLICK, clearLabel2);
txtinSideC.addEventListener(MouseEvent.CLICK, clearLabel3);

// This is the determineSum function
// e:MouseEvent is the click event experienced by the button
// void indicates that the function does not return a value
function determineSum(e:MouseEvent):void

{
    // declare the variables
    var SideA:Number;
    var SideB:Number;
    var SideC:Number;

    // get the Side Lengths
    SideA = Number(txtinSideA.text);
    SideB = Number(txtinSideB.text);
    SideC = Number(txtinSideC.text);


    // determine if the sum of any 2 side lengths is always greater than the remaining side length
    if (SideA + SideB <= SideC)
    {
        lblResult.text = "These sides cannot make a triangle.";
    }

    else if (SideB + SideC <= SideA)
    {
        lblResult.text = "These sides cannot make a triangle.";
    }

    else if (SideC + SideA <= SideB)
    {
        lblResult.text = "These sides cannot make a triangle.";
    }

    else
    {
        lblResult.text = "These sides can make a triangle.";
    }
}

// This is the clearLabel1 function
// e:MouseEvent is the click event experienced by the textinput
// void indicates that the function does not return a value
function clearLabel1(e:MouseEvent):void

{
    lblResult.text = "";
    txtinSideA.text = "";
}

// This is the clearLabel2 function
// e:MouseEvent is the click event experienced by the textinput
// void indicates that the function does not return a value
function clearLabel2(e:MouseEvent):void

{
    lblResult.text = "";
    txtinSideB.text = "";
}

// This is the clearLabel3 function
// e:MouseEvent is the click event experienced by the textinput
// void indicates that the function does not return a value
function clearLabel3(e:MouseEvent):void
