specified parameters.
// Receiving SWF
var aLocalConnection = new LocalConnection();
aLocalConnection.Trace = function(aString)
{
aTextField = aTextField + aString + newline;
}
aLocalConnection.Clear = function()
{
aTextField = "";
}
aLocalConnection.connect("trace");
stop();
SWF 1 contains the following code attached to a button labeled PushMe. When you push the
button, you see the sentence "The button was pushed." in the receiving SWF file.
on (press)
{
var lc = new LocalConnection();
lc.send("trace", "Trace", "The button was pushed.");
delete lc;
}
SWF 2 contains an input text box with a var name of
a button labeled Copy. When you type some text and then push the button, you see the text you
typed in the receiving SWF file.
on (press)
{
_parent.lc.send("trace", "Trace", _parent.myText);
_parent.myText = "";
