event-handling

I want to realize a simple JComponent-Drag-and-Drop with a preview from O.Reilly-Swing.Hacks Hack 69. Translucent Drag-and-Drop .

I have the CurrentCellChanged event handler of a DataGridView and i want to be able to access the current selected cells column index from the event handler.

Epilogue The problem was somehow related to the way jQuery normalizes event handling and how the eventObject data property changed

Is one way better than the other and why? Which one is better at
