Example #1 Usual interactions with buttons


<?php

$f = new SWFFont("_serif");

$p = new SWFSprite();

function label($string) 
{
  global $f;

  $t = new SWFTextField();
  $t->setFont($f);
  $t->addString($string);
  $t->setHeight(200);
  $t->setBounds(3200, 200);
  return $t;
}

function addLabel($string) 
{
  global $p;

  $i = $p->add(label($string));
  $p->nextFrame();
  $p->remove($i);
}

$p->add(new SWFAction("stop();"));
addLabel("NO ACTION");
addLabel("SWFBUTTON_MOUSEUP");
addLabel("SWFBUTTON_MOUSEDOWN");
addLabel("SWFBUTTON_MOUSEOVER");
addLabel("SWFBUTTON_MOUSEOUT");
addLabel("SWFBUTTON_MOUSEUPOUTSIDE");
addLabel("SWFBUTTON_DRAGOVER");
addLabel("SWFBUTTON_DRAGOUT");

function rect($r, $g, $b) 
{
  $s = new SWFShape();
  $s->setRightFill($s->addFill($r, $g, $b));
  $s->drawLine(600, 0);
  $s->drawLine(0, 600);
  $s->drawLine(-600, 0);
  $s->drawLine(0, -600);

  return $s;
}

$b = new SWFButton();
$b->addShape(rect(0xff, 0, 0), SWFBUTTON_UP | SWFBUTTON_HIT);
$b->addShape(rect(0, 0xff, 0), SWFBUTTON_OVER);
$b->addShape(rect(0, 0, 0xff), SWFBUTTON_DOWN);

$b->addAction(new SWFAction("setTarget('/label'); gotoFrame(1);"),
          SWFBUTTON_MOUSEUP);

$b->addAction(new SWFAction("setTarget('/label'); gotoFrame(2);"),
      SWFBUTTON_MOUSEDOWN);

$b->addAction(new SWFAction("setTarget('/label'); gotoFrame(3);"),
      SWFBUTTON_MOUSEOVER);

$b->addAction(new SWFAction("setTarget('/label'); gotoFrame(4);"),
      SWFBUTTON_MOUSEOUT);

$b->addAction(new SWFAction("setTarget('/label'); gotoFrame(5);"),
      SWFBUTTON_MOUSEUPOUTSIDE);

$b->addAction(new SWFAction("setTarget('/label'); gotoFrame(6);"),
      SWFBUTTON_DRAGOVER);

$b->addAction(new SWFAction("setTarget('/label'); gotoFrame(7);"),
      SWFBUTTON_DRAGOUT);

$m = new SWFMovie();
$m->setDimension(4000, 3000);

$i = $m->add($p);
$i->setName("label");
$i->moveTo(400, 1900);

$i = $m->add($b);
$i->moveTo(400, 900);

header('Content-type: application/x-shockwave-flash');
$m->output();
?>

This simple example will enables you to drag draw a big red button on the windows. No drag-and-drop, just moving around.

Example #2 Drag example


<?php

$s = new SWFShape();
$s->setRightFill($s->addFill(0xff, 0, 0));
$s->drawLine(1000,0);
$s->drawLine(0,1000);
$s->drawLine(-1000,0);
$s->drawLine(0,-1000);

$b = new SWFButton();
$b->addShape($s, SWFBUTTON_HIT | SWFBUTTON_UP | SWFBUTTON_DOWN | SWFBUTTON_OVER);

$b->addAction(new SWFAction("startDrag('/test', 0);"), // '0' means don't lock to mouse
      SWFBUTTON_MOUSEDOWN);

$b->addAction(new SWFAction("stopDrag();"),
      SWFBUTTON_MOUSEUP | SWFBUTTON_MOUSEUPOUTSIDE);

$p = new SWFSprite();
$p->add($b);
$p->nextFrame();

$m = new SWFMovie();
$i = $m->add($p);
$i->setName('test');
$i->moveTo(1000,1000);

header('Content-type: application/x-shockwave-flash');
$m->output();
?>
