| Summary | 0004872: Right click in TJvCheckedCombBox causes Stack Overflow.when Popup window open. | ||||
| Description | To reproduce the problem in the attached JVTest-OriginalCode.exe. 1. Click on the DropDown Button on the CheckedComboBox. 2. Then click with the Right Mouse button in the CheckComboBox edit control. Program crashes, Stack Overflow error. If item is (de)selected in drop down box either by Menu item or checkbox then crash does not occur. I could not see in the code why this makes the problem go away. P.S. Thanks to Glen for find the problem. | ||||
| Additional Information | To work around the problem I changed the following. Both the DateEdit and ComboBox then behave the same as in JVTest-FixedCode.exe. procedure TJvCustomComboEdit.MouseDown(Button: TMouseButton; Shift: TShiftState; X, Y: Integer); begin if (FPopup <> nil) and (Button = mbLeft) then begin if CanFocus then SetFocus; if not FFocused then Exit; if FPopupVisible then PopupCloseUp(FPopup, False); {else if (not ReadOnly or AlwaysEnable) and (not DirectInput) then PopupDropDown(True);} end; // Added 23/07/2009 // Fixed Bug if Right Mouse Button is pressed in control // Could check if FPopup.ClassName is TjvPrivForm as used in CheckedComboBox. if (FPopup <> nil) and FPopupVisible and (Button = mbRight) then begin PopupCloseUp(FPopup, False); end else // End of Added Code. inherited MouseDown(Button, Shift, X, Y); end; | ||||

I have just upload the source code. Delphi 2007 Project. JVCL : 3.37 (3.34 exhibited same problem) Same source for both projects, one compiled with existing JVCL code, the other with code as noted above. |

This is now fixed in SVN, with a slightly different approach |
