| Summary | 0006082: Fix for 5818 brought error in sizing columns in JvDBGrid | ||||
| Description | An reported error when autosizing columns in JvDBGrid (Mantis 5818) was "fixed" in 3.46. This "fix" however causes wrong columns to be resized when the grid is scrolled to the right. | ||||
| Steps To Reproduce | The attached project copies the example from 5818. I added an example for with more columns. To see the effect simply scroll the second table right and try to resize columns. | ||||
| Additional Information | To fix this I suppose to remove the fix in TJvDBGrid.CalcSizingState() and add this code at the end of this procedure: if Index > ColCount - 1 then Index := ColCount - 1; | ||||

Sorry I was too quick. Allthough this is not resolved in the last release build 3.47, I just saw, that this issue was covered again in the last builds. With this change it also works for me. |
|
|
With this change I can still produce an List Index Out Of Bounds Exception in the first example. In this example LeftCol is 1 and VisibleColCount is 1. So an Index of 2 could be calculated but it should be a maximum of 1. I think Index should be tested for ColCount-1. |

Hi frank, I tested your code but unfortunately is producing problem for the right-most column when is partially displayed. A fix is uploaded in 6069 issue. Regards, Stephen (ADG) |

Hi Stephen, my approach was simple and pragmatic to resolve the List out of bounds exception. I can produce no problem with it, even in the case you pointed out. What do you mean? I only handled the symptom and you went to the source I think. I can't produce any problems with either solution. Regards Frank |

Hi frank, thank's for replying, I reproduce problem only on the first column of the grid when displayed partially, it resizes the next column instead. Does NOT affect single-column grids. I'll be happy to hear from you again. Regards. |

Hi Stephen, you are right. I could reproduce this. Your fix seems to handle all cases I tested. I think it should be used for JVCL. Regards Frank |
