Warning
This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change in a future release of PHP without notice. Be warned and use this function at your own risk.

swfbutton() creates a new Button. Roll over it, click it, see it call action code. Swank.

SWFButton has the following methods : swfbutton->addshape(), swfbutton->setup(), swfbutton->setover() swfbutton->setdown(), swfbutton->sethit() swfbutton->setaction() and swfbutton->addaction().

This simple example will show your usual interactions with buttons : rollover, rollon, mouseup, mousedown, noaction.

Example 1. swfbutton() example
    <?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. swfbutton->addaction() 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();
    ?>
