[Chameleon] Query widget

Wed Jun 29 13:00:07 EDT 2005

Hello Bart and List,

Thanks for your response.

I have added some code to my html script, but it doesn't appear 
Chameleon is registering the event override, as the default query is 
still loading. The javascript code is this...

<html>
    <head>
        <script language="JavaScript" type="text/javascript">

            function OnPageLoad()
            {
                CWC2OnLoadFunction()
                goEventManager.registerForEvent('ON_QUERY', 
'OnQueryCustom');
            }

            function OnQueryCustom(nX, nY)
            {
                // Do custom query stuff here
                var url = 'query.phtml?x=' + nX + '&y=' + nY + '&sid=' + 
document.forms0.sid.value;
                window.open(url, null, "width=500, height=400, 
directories=no, location=no, menubar=no, scrollbars=no, status=no, 
toolbar=no, resizable=no");
            }

        </script>

    </head>

    <body    onload="OnPageLoad()" >
... rest of the page is here

... and this is my HTML code for the query widget...

<cwc2     type="Query"
            enabled="true"
            includeemptyresults="false"
            imagewidth="24"
            imageheight="24"
            visible="true"
            toolbar="false"
            radius="10"
            maxfeatures="5"
            menubar="false"
            status="false"
            popupwidth="500"
            popupheight="400">
            popupstyleresource="TextButtons"
            <image state="normal"   image="buttons/button_query_1.png" />
            <image state="hover"    image="buttons/button_query_2.png" />
            <image state="selected" image="buttons/button_query_3.png" />
</cwc2>

I'm certain my javascript is OK, so I am concerned that Chameleon is not 
doing something internally. I'm going to dig around in the example docs 
and wiki, but is there an "AllowOverrides" that must be set someplace? 
Or perhaps something else I am overlooking.

Best regards,
- Peter
