Hi all,

I'm currently engaged with developing an AWT Table, which can contain editable cells, and i'm stuck technically in how to enable scrolling.
In horizontal scrolling scenario, i just want to synchronize scrolling the cells data area and scrolls the header area. In vertical scrolling scenario, i want the header row area to stay on top, like the spreadsheet header.

I assume the correct way to enable scrolling in AWT is to do the following :
1 create one panel for header at the top
2 create another panel for the data cells
3 add an invisible horizontal scrollbar for the header panel
4 add visible horizontal and vertical scrollbar for the data panel
5 when scrolled vertically, the header panel is unaffected
6 when scrolled horizontally, the header panel also scrolls, which updates his own graphics

And i have no idea how i'm gonna implement step 6, about how to synchronize the horizontal scrolling. Anyone got a simple example ? Or perhaps there are easier ways to do this ?

Thanks,
Albert Kam
