Inside the browser you can do HTTP requests using XMLHttpRequest https://developer.mozilla.org/de/docs/Web/API/XMLHttpRequest/Using_XMLHttpRequest or open a WebSocket connection https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API/Writing_WebSocket_client_applications. I am not aware of any TCP socket support. > 2) I need to "clear" the display when a new dump begins, and draw the > brand new dump. Any thought on how to do that? Are you using SVG within HTML? Or solely SVG? In any case, using W3C DOM scripting you can remove nodes and insert new ones respectively replace nodes. On the other hand if you want to replace the whole document displayed every 10 seconds then a HTTP refresh *https://en.wikipedia.org/wiki/Meta_refresh) might be easier, assuming your legacy app can do HTTP instead of TCP. > 3) I will eventually need some event handling, especially mouse > clicks. The SVG elements have event handler attributes, see http://www.w3.org/TR/SVG11/script.html#EventAttributes and you can also attach event listeners using the W3C DOM method addEventListener. --- news://freenews.netfront.net/ - complaints: news@netfront.net ---
