Simple div. Tied to a lat/lon, not an object. Always opens in a single direction. Generally not used: doesn't fit itself to the right area of the map, and doesn't provide a 'pretty' UI. > 2) OpenLayers.Popup.Anchored Simple div, tied to an object (like a marker) which provides an 'offset'. The offset is used to place the popup based on the lonlat, and the offset, based on the preferred relative position -- top left, bottom right, etc. Thsi is automatically calculated based on where the lonlat is in the map, designed to open the popup in the directin with the most space. > 3) OpenLayers.Popup.AnchoredBubble Same as above, but with rounded corners using Rico.Corner. > 4) OpenLayers.Popup.Framed Base class for image-based popups, which can be fixedRelativePosition or not. An image (defined in a property of the popup) is used to create the "GUI" aspect of the popup. A base class, this is never meant to be used excpet for extension. > 5) OpenLayers.Popup.FramedCloud A specific instance of the above: Provides image properties for a popup. > Seems to me like all popups are "anchored" and I can't tell what is the > implied distinction in the words "bubble" and "cloud". Anchored means 'has an offset, and can be offset relative to the position of its 'anchor'' > None of the above shed much light on the question "why so many, and > which to use when?" I don't know if thsi helps at all, but, there it is.
