Spacetree: Some 'ellipse' nodes are not shown in IE about jit HOT 7 CLOSED

Hi,

This is actually an ExCanvas bug. I recommend you to use FlashCanvas for IE support. It has better performance and from what I've seen works very well. You can try the FlashCanvas example here: http://flashcanvas.net/examples/thejit.org/static/v20/Jit/Examples/Spacetree/example4.html .

Here's the blog announcement for more information http://blog.flashcanvas.net/2010/07/flashcanvas-pro-13-beta1-is-released.html .

Hi Phil,
It's not that simple. I was using FlashCanvas, but there were actually two issues involved.

1. Break in IE6, but work in IE8 if simply change node type from 'rectangle' to 'ellipse'. So this could be a issue of whether FlashCanvas supports IE6 or not.
2. Break in IE8 if change node height from 40 to 60. The root node is not shown. The ellipses were drawn first, then seem background colors were changed to black except the last node. I would reckon the nodes are still there(because tips still work) just not being shown. P.S. my first level nodes under root were 8. So this could be an issue of undocumented size limit of the canvas? Once that limit is exceeded, it breaks.

If there's a JavaScript error in IE6 but not in IE8 there's a big chance you left some trailing comma somewhere in your JS code. The demo I sent you using Ellipse nodes works well with IE6 with FlashCanvas.

If the height of the Tree exceed the height of the canvas then that level is not shown by default (this is a feature of the SpaceTree acually). To turn it off you have to set

constrained: false

as constructor option in the visualization. More info here: http://thejit.org/static/v20/Docs/files/Visualizations/Spacetree-js.html#ST .

Could you paste the JSON you're using and if possible a screenshot with the issue?

Sorry I don't know how to upload screenshot to github?

Try uploading it to any pic service like imgur.com and then share the link.

that's with excanvas, right? what about flashcanvas? the example I linked you to uses flashcanvas and works just fine.
