<DIV><FONT face=Arial size=2>Hello Chameleon users, </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Iīve noticed in the 'Samples' included with the
Chameleon software, that the 'Query' Widget works based on one 'point'
input and not<BR>a region. From the beginning I thought that regions obtained
with the 'ROI tools' were going to be combined with the 'Query' or
'ExpressionBuilder' widget. <BR>If there exist any combination like that someone
have heard about it, I would really appreciate if you can share it.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Following the examples in Chameleon, I
wanted to understand the sequence of work from the
'ExpressionBuilder' widget.<BR>But when using 'Build filter' tool,directly
in the the interfase, I always get the following message, even when I have
activated(not just selected) some layers:<BR>"Invalid layer or none selected.
Please ensure that the selected layer is a WFS or WMS layer" </FONT></DIV>
<DIV><FONT face=Arial size=2>I am not sure if the examples of Chameleon are WMS
layers.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I couldnīt find also, examples of how to use the
SQLQuer, I would like to know if is possible to connect one database, through a
POSTGIS connection, using the 'SQLQuery' widget,<BR>since I have read comments
related only to MYSQL.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Being a newbie in Chameleon and not having much
knowledge in programming, but basic concepts,<BR>I would like to ask is,if
someone knows of examples putting to work any of the previous
mentioned capabilities, and if I can get a hint of how to start from
scratch, to understand<BR>these 3 widgets.</FONT></DIV>
<DIV><FONT face=Arial size=2>Thanks in advance for your valuable
help!</FONT></DIV>
