Richard,
To do this, I have a blank layer and switch from my main map layer to the
blank layer by using the setBaseLayer function.
My blank layer is defined as follows:
var layerBlank = new OpenLayers.Layer.Image(
'No Map',
'../images/BlankMap.gif',
new OpenLayers.Bounds(0, 0, 670000, 1230000),
new OpenLayers.Size(8, 8),
{
isBaseLayer: true,
displayInLayerSwitcher: false
}
);
myMap.addLayer(layerBlank);
myMap.setBaseLayer(layerBlank) or your actual map layer. Switch between the
layers using this function.
BlankMap.gif is an 8 px x 8px white image.
I hope this helps.
Regards,
Donald

Subject: [OpenLayers-Users] Hiding map temporarily
I am driving the web browser from an external program, and I'm trying to
figure out how to "hide" the map temporarily - that is, clear the browser
pane to white until I want to display the map again.
I have experimented with using map.render() to switch between two divs one
of which is "display : none" but this causes all kinds of weird behaviour
with the marker, and loses styles in the vector layers, so I guess this is
not the way to go.
I can't find any OpenLayer.Map methods to make the whole map
hidden/invisible.
Can anyone suggest how I can do this?
