<DIV><FONT face=Arial size=2>Sorry if this mail reaches the list twice, the
first mail seems to have bounced. To be sure it arrives, I'm sending
it again and also with some changes.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Hi,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have been playing around with chameleon for some
time now and everything seems to work perfectly. Great work! </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>My only doubt so far is about postgis layers. I
have a postgis layer with several lines, a lot of them actually,
and</FONT></DIV>
<DIV><FONT face=Arial size=2>would only like to display a selection of
lines based on user input. I would like to make a
dropdown/combobox</FONT></DIV>
<DIV><FONT face=Arial size=2>with some predefined values and a button. When
selecting the value from the combobox and then pressing the</FONT></DIV>
<DIV><FONT face=Arial size=2>button it should use the selected value of the
combox in a heavy* query and display the result (a bunch of lines) on the
</FONT><FONT face=Arial size=2>map. I have been able to get this to work in a
normal mapscript application, but don't know how to aproach
this, using chameleon.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I´ve read on the mailing list it's possible to
manipulate the map in the initializer file. </FONT><FONT face=Arial size=2>What
would be the best way the do this? I assume I have to create a widget for this
as well to allow user input. Does anyone have any examples for this or some
hints on where to start? </FONT></DIV>
<DIV> </DIV>
<DIV>I already successfully managed to filter a layer based on parameters in the
URL and then zoom in to the results of the filter, by messing around in the
initializer file. I imagine that there must be a cleaner way to do it,
right?</DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks in advance!</FONT></DIV>

<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>* The query contains a pathfinding algorithm, so it
would be nice if I would only have to execute the query when the user changes
the selection</FONT></DIV></FONT></DIV></BODY></HTML>
