I've created a simple application with an NSTableView. I have
written a delegate for this table,
numberOfRowsInTableView:objectValueForTableColumn:row:, that returns
the number of rows in the table when requested.
My application uses the table view to display hexadecimal data on a
flash memory chip, with 16 bytes displayed per row. As a test, I
tried returning a large number for the number of rows, 0x1000000.
When I scroll through the table, everything looks okay for the first
14 million rows or so, after which the gray horizonal cell separator
disappears and the row data begins to shift by a pixel per row,
until it eventually is superimposed on the row above it. This seems
like a bug with the NSTableView class, but perhaps I'm doing
something wrong. Has anyone else run into this problem?
My 2 cents,
If you're looking for a (very) efficient and clean way to display
large amount of binary data, have a look at HexFiend. This is the
fastest hex editor I know. It's able to handle multi Gbytes files
smoothly and without problem (and it's distributed under modified BSD
license).
