[OpenLayers-Users] Drawing "Area of Interest" rectangle

[Armin Burger]

Hi all

I'm looking for a possibility for a tool that allows a user to draw a 
rectangle on the map that is used as area of interest for a spatial 
query. The rectangle should persist on the map so the user still sees 
for which region he was searching.

I tried a Control.DrawFeature with a Handler.Box. This draws a rectangle 
but it disappears after drawing.

If I use the Handler RegularPolygon then I have not found how to limit 
the drawing to a straight rectangle (I got just a square that a user can 
still turn). In addition, this drawing is added to a layer and this 
layer is visible in the LayerSwitcher. Is there a possibility to avoid 
the drawing layer being added to the Switcher?

Thanks in advance for any hints or pointing me to an example.
