[Chameleon] Creating my own Widget

When I created my Nav tools widget I needed to add some changes to the
MapDHTMLWidget.js file in the MapDHTMLWidget folder in the widgets
Open that file and look in the functions:
MapWchkMouseUp, MapWmapTool, and MapWgetMouse.
There are parts in each of those that look something like this:
if((window.gMapDHTMLForm != null) &&
(gMapDHTMLForm.NAV_CMD != null) &&
(gMapDHTMLForm.NAV_CMD.value == "PAN_MAP" ||
gMapDHTMLForm.NAV_CMD.value == "RULER" ||
gMapDHTMLForm.NAV_CMD.value == "QUERY" ||
gMapDHTMLForm.NAV_CMD.value == "GetPoint"))
Its slightly different in each one, but you will be able to recognize
it. GetPoint is my widget, you can see how I added it there. Basically
since QUERY is in every one I suspect that a query type widget also
needs to be there, so put your own widget name in those lists.

Subject: [Chameleon] Creating my own Widget
I am trying to create my own widget and I am running into some problems.
am trying to create a hotlink widget which will work similar to identify
will open a webpage when the location on the map is clicked. I plan to
this by copying and modifying the query widget.
I started by simply copying the query widget and renaming it. I wanted
check that it still worked once the name has been changed. It doesn't!
far, I changed the folder name to Hotlink, I have changed
to HotlinkResults.phtml and Query.widget.php to Hotlink.widget.php. I
also changed in Hotlink.widget.php the class and constructor names from
Query to Hotlink (as per instructions in an old thread I found in the
When I click on my hotlink button the map redraws and nothing happens.
click the same point with my identify/query button I get a popup window
the query results. Since I haven't changed any of the actual
yet, both buttons should produce the same results.
Are there other places where I have to change/add to files so that my
widget will be recognized? In an older message someone mentioned
the MapDHTMLWidget.widget.php but I couldn't tell where it should be
(I did a text search for query).
Any help would be appreciated.
