Hi Rob
I don't see any references to autoscrollpopup anywhere. Are you saying
that instead of:
<popupset id="mainPopupSet">
<panel id="test-panel" style="border:0 none;background-
color:transparent;-moz-window-shadow:none;" level="top"
noautohide="true">
<html:canvas id="mycanvas">
</html:canvas>
</panel>
<script type="text/javascript">
<![CDATA[
function blah()
{
var el=document.getElementById('test-panel')
canvas =
document.getElementById("mycanvas"),
cg = canvas.getContext("2d");
cg.strokeStyle = "green";
cg.strokeRect(20,20,50,50);
canvas.width = document.width;
canvas.height = document.height;
el.openPopup(document, 'overlap', 0, 0, false, false);
}
]]>
</script>
</popupset>
I should be using:
<popupset id="mainPopupSet">
<autoscrollpopup id="test-panel" style="border:0
none;background-
color:transparent;-moz-window-shadow:none;" level="top"
noautohide="true">
<html:canvas id="mycanvas">
</html:canvas>
</autoscrollpopup>
{script etc.}
</popupset>
?
