It seems, the repeat function isn't working. > Under gtk pressing the scrollbar arrows does one pixel position increment (I'm not sure if this can be changed), as you probably has thousands of rows every one at least 18 pixel height, you would have to press at least thousands*18 times in order to scroll the grid fully ;). > The main view he refers to is TDrawGrid any idea how I can fix it ? > for 4a, you probably need to make a T*DrawGrid derivated that handle the scrollbars in a different way, for example look at dbgrid on how to do that, specially tcustomdbgrid.UpdateScrollbarRange, in your case one pixel will probably mean one record, so clicking the scrollbar arrows will move one record. > Ciao > A.J. > -- > "there's nothing as inspirational for a hacker as a cat obscuring a bug > by sitting in front of the monitor" - Boudewijn Rempt > A.J.
