| Summary | 0004381: Tjvdbgrid scroll using wheel mouse | ||||
| Description | Jvdbgrid scroll behaviour is wrong when wheel mouse is used. There is no scroll problem when the “alternaterowcolor” property is set to another color than “clNone”. | ||||
| Tags | No tags attached. | ||||
|
|
This problem occures since revision 11798 |
|
|
scroll problems can be fixed by removing the scroll switch sentences from this procedure. procedure TJvDBGrid.MouseWheelHandler(var Message: TMessage); var LastRow: Integer; begin // DisableScroll; // try LastRow := Row; inherited MouseWheelHandler(Message); if (Row <> LastRow) and (DataLink <> nil) and DataLink.Active then InvalidateCell(IndicatorOffset - 1, LastRow); // finally // EnableScroll; // end; end; |

I hope this change doesn't break any older bug fix. I've added the DisableScroll/EnableScroll in my last bug fix because I ran into a bug if they were missing. Unfortunately I don't remember what this bug was and if the actual cause for the problem was fixed in a newer revision than the one I have at work. |
