[Chameleon] Creating Widgets

Hello all. I took a first stab at creating a widget, actually it was
more editing of other widgets, but I did get it working and I had a
couple general questions.
In order to get it to work in the end I needed to manually add my widget
tool name to several parts of MapDHTMLWidget.widget.php. Is there a way
to make this get automatically added from your specific widget php file?
For example, I changed the following in the MapWchkMouseUp function:
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"))
My change is the GetPoint portion line which I needed added. Basically I
am wondering if I can invoke that change, which was also added to the
MapWgetMouse and MapWmapTool functions, at my widget rather then in the
MapDHTMLWidget itself, which means I wont need to go back and change
that file every time I upgrade Chameleon.
My other question is in regards to functions. Is there any check for
adding duplicate functions from different widgets? Basically I use a
function from the CursorPos widget in my widget. Can I add the exact
same function to my widget in case CursorPos isnt loaded or will that
cause two functions of the same name to be outputted to the HTML file?
