[OpenLayers-Dev] [OpenLayers-Trac] [OpenLayers] #966: Add att ribution control to map by default

[John Cole]

Christopher, 
  Yea, I was concerned that it would always be there :-)  Right now,
printing is a PITA, but I'm hoping to have time to work on a solution I
*think* might work.

  This involves making sure all controls and layers have an additional
'noprint' css class on their containers.  Then if a style sheet with a media
option for print is available, it can set the 'noprint' class display: none,
and that should remove all layers and controls.  The trick of course is to
have a base layer with the opposite true, it only gets turned on for the
printing style sheet.  

  I'm hoping that this scheme will allow users to simply hit 'print' from
their browsers and have the maps print out correctly with the rest of the
page, instead of having a separate page for printing.

John

Ah, then your'e fine with this: this only adds it to the map by
*default* -- that is, if no  controls:[] option is specified on the map.
If you specify controls: [], then the control isn't added -- I think
this was Paul's question as well, which I hope I adequately responded to
there. 

This is *only* for the 'standard' default OL map -- if you want to
customize your map, we're not going to force you into a specific
direction. 

With that in mind, do you forsee a problem? or was your concern just
that it would be added to the map regardless of what was specified in
the map intializer control list?
