| Summary | 0004867: TJvXPBar causes access violation when Actions are removed at runtime | ||||
| Description | If action are removed from a TJvXPBar at run time on the mouse entry into the component it will raise an access violation. The issue appears to be due to FHoverIndex no longer being valid. Solution to my problem was resetting FHoverIndex := -1; after a ResizeToMaxHeight. This may not be the best location; but it am updating the items during a BeginUpdate, EndUpdate block and ResizeToMaxHeight is called. | ||||
| Additional Information | procedure TJvXPCustomWinXPBar.ResizeToMaxHeight; var NewHeight: Integer; begin { TODO: Check this!!! } if IsLocked then Exit; NewHeight := FC_HEADER_MARGIN + HeaderHeight + FVisibleItems.Count * FRollOffset + FC_ITEM_MARGIN + 1; { full collapsing } if ((FRolling and not FCollapsed) or (not FRolling and FCollapsed) or (FVisibleItems.Count = 0)) then Dec(NewHeight, FC_ITEM_MARGIN); // if Height <> NewHeight then Height := NewHeight - 5 + FTopSpace; // Tristan Marlow FHoverIndex := -1; end; | ||||
