Hello,
I want to display a map with two different zoom levels, 3 zoom levels for the
whole map extend and 6 levels for a detailed section in the center of the
extent. I do this with a zoomend event handler, in which I set restrictedExtend
to the detail area when the user zooms to level 4.
map.events.register('zoomend', this, function (event) {
var zLevel = map.getZoom();
if( restricted && zLevel < detailZoom) {
restricted = false;
map.setOptions({restrictedExtent: fullExtent});
}
if( !restricted && zLevel == detailZoom){
restricted = true;
map.setOptions({restrictedExtent: detailExtend});
}
});
This works fine but makes the map 'jump' to the detail area when the user zooms
in while the mouse is outside the detailed area. Therefore I am looking for a
way to disable zooming in while the cursor is outside the detail area. I know
how to track the mouse position, but did not find a way to limit the minimum
zoom level dynamically. Any hints are welcome.
Rainer
