Getfocus (Selection.getfocus Method) - MACROMEDIA FLASH 8-FLASH LITE 2.X ACTIONSCRIPT LANGUAGE Reference

Example
In the following example, you create two input text fields at runtime, setting the borders for
each text field to
true
. This object defines for itself an
focusListener
function. The function takes two parameters: a reference to the text field that lost focus, and
one to the text field that gained focus. The function sets the
that lost focus to
false
:
true
this.createTextField("one_txt", 99, 10, 10, 200, 20);
this.createTextField("two_txt", 100, 10, 50, 200, 20);
one_txt.border = true;
one_txt.type = "input";
two_txt.border = true;
two_txt.type = "input";
var focusListener:Object = new Object();
focusListener.onSetFocus = function(oldFocus_txt, newFocus_txt) {
oldFocus_txt.border = false;
newFocus_txt.border = true;
};
Selection.addListener(focusListener);
When you test the SWF file, try using Tab to move between the two text fields. Make sure
that you select Control > Disable Keyboard Shortcuts so you can change focus between the
two fields using Tab.
