Hi all!
I have view-based NSTableView with 10 columns. Each cell is NSTableCellView with NSTextField on it (default). Auto-layout is OFF. OSX 10.8.2.
Table has 1000 rows. Datasource is AppDelegate with only one method:
- (NSInteger)numberOfRowsInTableView:(NSTableView *)tableView {
return 1000;
}
If the window with table view is big enough, when I scroll the table using keyboard arrow keys, selected line goes down off the screen (or up), then jumps up(down) and all over again. In other words - scroll is slow and jerky.
However, if I hit Home or End key - then scroll is fast and nice. Why that happens?
(This happens on Mac mini3,1 early 2009, 2Ghz Core 2 Duo, NVIDIA GeForce 9400, but I don't think what that issue related to hardware)
