Thanks, Mark, this was very helpful but ultimately I didn't need to
use the hack...you were right that it was trying to draw into a div
that was not rendered, so if I had been able to find a good way to get
a callback after things were drawn that probably would have worked.
But I realized that I could do the same thing by calling the callback
function myself, after the calls to addDynamicTab were complete. In
the code above, I just added the last line in this snippet:
if (tabs == null) {
var tabdiv = _gel('tabs_div');
tabs = new _IG_Tabs(__MODULE_ID__, tabnames[0], tabdiv);
for (i=0; i<tabnames.length; i++) {
tabs.addDynamicTab(tabnames[i], tabcallback);
}
tabcallback(1);
}
An alert showed me that the first time the callback function was
called, no tabs had been drawn. If I had been adding HTML to the
innerHTML of a div, like the examples show, that would have been no
problem. But since the visualization was drawing in a container that
hadn't been fully set up, it wasn't showing up properly.
