NAME

makelabel, setlabel - create and set HTML text

SYNOPSIS

makelabel( s )
setlabel( n, s )

DESCRIPTION

makelabel() creates a new label tag with the text specified by string s on the HTML pop up page. It returns an integer identifier that can be used to refrence the label and change the text displayed.

Like other Tranquility functions that create HTML elements, makelabel() opens a new browser window when called if one had not already existed.

setlabel() changes the text in the label identified by the first argument n to the string s specified by the second argument. n should be an integer identifier returned by an earlier call to makelabel()

Labels will be placed on the HTML page, left to right, top to bottom in order of being called.

RETURN VALUE

makelabel() returns an integer label identifier.

setlabel() does not have a return value.

EXAMPLE

fun init () {
     var imgA, imgB
     var labelA, labelB

     imgA : makeimg()
     labelA : makelabel()
     imgB : makeimg()
     labelB : makelabel()


     setimg( .imgA, "dog.png" )
     setlabel( .labelA, "This is a picture of a dog" )
     setimg( .imgB, "cat.png" )
     setlabel( .labelB, "This is a picture of a cat" )
}
