[Chameleon] Print Widget Output and Query

[Rene Teniere]

Paul and Bart,

I tried what you suggested and everything worked. The only thing is
that the query seems to be really finicky and will only pick up the
polygons. The lines and points will not show their attributes in the
query, even though I set the radius=100. This does not seem to work,
even on the polygons. I have to be within it in order to pick it up. I
know the documentation says that it may not be supported by all servers,
but am I looking in the wrong place? Is this a tolerance issue?

The print preview worked great, I tried looking for that section in the
code yesterday but I seemed to have missed it. It would be great to have
the legend located outside the map so clients can have the full map view
without any obstructions when printing, but that's not as important as
getting the basic functionality set up first.

Just to make sure, the legend in the print preview is a bug? 
Legend Output:

*Airphotos                   ->Group Name
    Airphoto Centres     ->Class Name
*Airphotos
    Lake and Water Bodies
*Airphotos
    Rivers and Streams
*Airphotos
    100 Series Highway
    Trunk Roads
    Secondary Roads
    Railway
*Airphotos
    Shoreline
*Airphotos

Thanks,
Rene

Hi Rene,

to answer your first question.

There is an option popup widgets have for this which you could use in
the 
CWC2 tag of the Print widget (Menubar="false"), but I am not sure if
this 
applies to popup windows emerging from the popup widget, like the
preview 
print does.

If this does not work you could hack the code:
Look for the window.open function in production.pthml and add
menubar=yes 
to the options argument of the function.

For the Query widget to work your layers in the MAP file should have
the 
following:

DUMP TRUE
STATUS ON
template "blank.html"

and for WMS layer not the following METADATA:
wms_queriable "0"

Hope this helps.

Best regards,
Bart

Rene, answers in line.

in the widget tag for the PrintWidget, you can set the menu="true" 
attribute to get the file menu in the Map Production popup, but that 
doesn't affect the printer friendly view unfortunately.  I will see
what 
can be done about that, I think it should be possible to allow the 
settings that opened the Map Production page be passed on to the popup.

  Now that I think about it, though, I think that the file menu should

be on by default in the printer friendly preview :)

I can't add this change to CVS right now, but if you open 
production.phtml and find the line that opens the preview window (on 
line 316 in my copy)

         preview = window.open( "./preview.phtml?<?php echo 
SID."&selImageFormat=".$selImageFormat ?>",
                                   'preview',
 
'status=no,toolbar=yes,scrollbars=yes,resizable=yes,width=800,height=600,screenX='+xOffset+',screenY='+yOffset+',top='+yOffset+',left='+xOffset+'');

the third line starts with status=no.  Edit this line to include 
menubar=yes at the beginning, as in:

'menubar=yes,status=no,toolbar=yes,scrollbars=yes,resizable=yes,width=800,height=600,screenX='+xOffset+',screenY='+yOffset+',top='+yOffset+',left='+xOffset+'');


I will commit my change soon so you will be in sync with the latest 
version if you update.

ok, can you file a bug on this if there isn't already one in the 
chameleon bugzilla on maptools.org please.

yes, you need to add a tag to any layers that you want to be queryable,

as in:

LAYER
  ...
  TEMPLATE "ttt.html"
END

the "ttt.html" can be anything, it doesn't really matter but MapServer

uses this value in CGI mode to display query results and it doesn't
make 
a difference between MapScript and CGI mode, so you have to set
TEMPLATE 
to something to make a query happen.  The QUERYMAP object is used to 
draw highlighted features after a query, since Chameleon doesn't redraw

the map after a query, this won't do anything.  It may be changed in a

future version, or become an attribute of the query widget.  But for
now 
it doesn't do anything.
