Update of /cvsroot/quantproject/QuantDownloader/Downloader In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv22862/Downloader Modified Files: GroupEditor.cs TickerGroupsViewer.cs Log Message: TickerGroupsViewer is now usable (it will be completed soon). It is now possible to do these operations: - adding, renaming, removing groups from the treeView (the structure); - selecting tickers from the listView (the content of the selected node in the structure view) and performing, on those tickers, validation or download from the web.
