[OpenLayers-Users] FramedCloud and autoSize

[Matthew Atkins]

Wendell,

As Chris mentioned the patch to ticket 1570 is not the entire solution.
You will need to watch out for how you are defining your CSS with the
FramedCloud content. The getRenderedDimensions() function creates a new
DIV off-screen in order to calculate the size of the HTML content
dynamically but it does not inherit the CSS rules like
".olFramedCloudPopupContent" and it is not inserted at the same level in
the DOM hierarchy (it's appended to the document's BODY).

So if you write CSS for your popup's content with selectors like:

.olFramedCloudPopupContent h2 { /* rules */ }
.olFramedCloudPopupContent table { /* rules */ }
.olFramedCloudPopupContent p { /* rules */ }

The styles will be applied to the content when it shows within the popup
on-screen but the calculated size will be incorrect because the CSS
rules were not applied (do not match) off-screen.

Yes, the patch works great!  Thanks to Wally Atkins and the
rest.  I'll also try the margin padding, that should help.
