Hi,
How to get the current map bounds given that I have map object handle. The
map API says getExtent returns the current view port bounds in lat lon. But,
When I used this function , I get undefined. Is there any other options to
get current map bounds and height , width values ??
Sorry.
used getExtent on wrong instance. I used it on Layer not on map. Now used on
map instance and It worked.
But, I could not find any functions to get the width and height values of
current map.
Any suggestions and help are much appreciated.
Thanks,
Kalyan.

Hi all
I am wondering if there is a way to use the split control to split line
features programmatically rather than by a user identifying on a sketch
layer where a split should be made?
I can determine in javascript where I want to split the feature and I don't
want the user involved -
Hi Imran,
if you want to extent the layer switcher with custom functionality, the
cleanest way is to derive your own CustomLayerSwitcher class from
Control.LayerSwitcher.
You just need to redefine the redraw() method, where all the HTML of the
Control is assembled.
Hi,
you mean this?
var winWidth = map.getSize().w;
var winHeight = map.getSize().h;

Yes. This is what I was looking at.
Thanks for that Arnd and Franz.

Hi
Why is it not possible to use '.' (point for singleChar) in a
OpenLayers.Filter.Comparison.LIKE?
The Comparision filter 'like' seems not to work as expected.
It's not possible to use an expression only with a point for a single char
(.2) or a static string (22).
It causes an error
It does not seem an ideal design to me.
Is there no way to provide caching (maybe by setting the correct http
headers) so that the backbuffer tile will come from the browser's cache?
Or are your async requests using POST and not GET?

the problem here is, when

Hello Bart,
Thanks for the reply.
I have tried e.layer.name and e.layer.map.baseLayer.name and both provides
me the previously selected layer's name.
Is there events that I should listen instead of map's changelayer event?
Maybe there's something for LayerSwitcher?

Hi Mengu,
I suppose you want to detect the newly activated baselayer in the layer
switcher.
If you activate a new baselayer in the layer switcher, you actually trigger
2 changelayer events: 1 for the old baselayer (because it gets invisible)
and 1 for the new baselayer (because it gets visible).
Hi Alexandre,
thanks for your reply! I tried using
OpenLayers.Handler.Feature.prototype.clickTolerance=100/1000/100; , but
it makes no difference. It does get stored, because when I do
alert(OpenLayers.Handler.Feature.prototype.clickTolerance); it does show the
correct value.

My bad. the 'clickTolerance' of the GetFeature control has not the
same purpose as the 'clickTolerance' of the Feature Handler :

Hi,
I want my openlayers map to fill the whole browser window, it should only
leave 200px left and 150 px top offset for UI Elements.
Here is my css for the map div:
.fluid-map {
position: absolute;
left: 200px;
right: 0px;
margin: 0px;
Can someone give me some hints about how reproduce this effect

Hi Pierluigi,
My first unch would be to look at the transitionEffect attribute of a layer.
Here the tiles are resized to fit the next zoomLevel before the new tiles are
loaded. I guess you could use this effect to magnify a part of the layer

Met vriendelijke groet, Kind regards,
Have you looked into the http://opengeo.org/community/suite/ OpenGeo Suite
package? This includes a http://suite.opengeo.org/geoexplorer/ GeoExplorer
application, which supports the ability for users to compose and publish
maps based, which can be saved to a database and hyperlinked to.
Not a fix, but rather a work around. Try setting a height and width to your
div manually. It is likely to break your absolute positioning unless you
setup a helper JavaScript function to detect what the width and height
should actually be.

Hi All,
I have a problem with rendering WFS feature near the dateline along with a
WMS layer (with wrapDateLine=true). The feature location is: 173.71,-40.19.
At first the feature is shown fine, but when the map is moved toward the

However, there is one drawback - it responds to clicks on the PanZoomBar

zooms.
It doesn't respond to the Zoom In or Zoom Out icons - just
