Re: [Mapbuilder-devel] MapPaneOL

[olivier.terral <oli...@ge...>]

Hi Cameron


I begin to integrate basic widget in MapPaneOL (zoomIn,zoomOut,drag pan=20
and reset).

I' ve do an observation.  The extent.js file  isn't  used  ,  this=20
observation seems to be logical because extent.js  was created for the=20
old MapPane .
And OL functions permitts  to have useful information on  Resolution ,=20
Scale and other.

At this time , I talk only for basic widget, my investigation only begins
 but I think this file  could be deprecated in the future.

Cameron, what do you thinking  about?
=20


Now I 've only integrated zoomin,zoomout but I've a better knowledge of=20
the problem

Can I created a new branches on svn because  my modif break all=20
Mapbuilder code base?
or if you have another solution, tell me?

bye

PS: thanks for your answer on IRC last day.
