Description

object swfbutton ( void )

Warning

This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change without notice in a future release of PHP. 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();
?>
