Re: [Jmol-users] Prevent applet resizing with browser zoom?

[Robert H. <ha...@st...>]

1. You know what size the applet is initially, because your callback will
report it.
2. You know what the applet size is in CSS by checking that
(document.getElementById("jmolApplet0").style.width, I think).
3. When the page opens and you get the resizeCallback, you correlate those.
4. If you get a resize callback you should be able to know if YOU did the
resize or the user did through zoom settings.
5. The CSS will report the new size, and Jmol will, too, perhaps. I don't
know.
6. Then just adjust the applet size to match the old size, making sure to
set a flag that disables the code in the callback for this next resize.

Right?
