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();
?>`
