<DIV><FONT face=Arial size=2>Hallo,</FONT></DIV>
<DIV><FONT face=Arial size=2>I have two layers named "topography" and
"parks".</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Instead of using the checkboxes to show and hide
the layers I want to use a button that calls the following function to hide
the layer:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>function test_hideLayer()</FONT></DIV>
<DIV><FONT face=Arial size=2>{</FONT></DIV>
<DIV><FONT face=Arial size=2>
<DIV><FONT face=Arial size=2>
Events.triggerEvent('removelayer', 'parks');</FONT></DIV></FONT></DIV>
<DIV><FONT face=Arial size=2>}</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>and another button that calls the following
function to show the layer:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>
<DIV><FONT face=Arial size=2>function test_showLayer()</FONT></DIV>
<DIV><FONT face=Arial size=2>{</FONT></DIV>
<DIV><FONT face=Arial size=2>
<DIV><FONT face=Arial size=2> Events.triggerEvent('addlayer',
'parks');</FONT></DIV></FONT></DIV>
<DIV><FONT face=Arial size=2>}</FONT></DIV></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The code does not work. Can somebody
help?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Cheers, Vojko</FONT></DIV>
