Just read about the new virtual tree widget ! Very cool, this helps with large datasets as the dom manipulation is done on a 'need to' basis and not all at once ...
so I modified the sample in the demobrowser: http://tinyurl.com/5tgpezd to add 100'000 nodes to the Network node but no joy ... it takes my browser a minute todo that ... If you open the log window in the playground you can see that preparing the array with data took less than a second while the marshalling of the data took about 50 seconds and appending the data to the existing tree took another 12 seconds. Doesn't this sort of defeate the purpose of the virtual tree/list. Are there any thoughs on how to make this more dynamic ? For the the branches of the tree it is pretty simple todo as they can be populated upon opening this works even with the current model, but inside a large branche I don't see any way to provide content dynamically ... cheers tobi -- Tobi Oetiker, OETIKER+PARTNER AG, Aarweg 15 CH-4600 Olten, Switzerland http://it.oetiker.ch [email protected] ++41 62 775 9902 / sb: -9900 ------------------------------------------------------------------------------ The ultimate all-in-one performance toolkit: Intel(R) Parallel Studio XE: Pinpoint memory and threading errors before they happen.
