| Summary | 0005052: TJvDBGrid handles OnKeyPress event twice | ||||
| Description | A TJvDBGrid handles an OnKeyPress() event twice. One time correctly, one time with var Key equal to #0. Notice: "dgEditing" in "Options" must be set to "true". | ||||
| Additional Information | begin >>>> inherited; <<<<< ...ist it necessary? (line 2720) if Assigned(FCurrentControl) then begin if FCurrentControl.Visible then PostMessage(FCurrentControl.Handle, WM_CHAR, Msg.CharCode, Msg.KeyData); end else if InplaceEditor = nil then DoKeyPress(Msg); // This is needed to trigger an onKeyPressed event when the // default editor hasn't been created because the data type // of the selected field is binary or memo. end; | ||||

from the user saying "Notice: "dgEditing" in "Options" must be set to "true". " I get the idea that this "twice" bug might be a conflict between the JVCL component and the changes in the base VCL class in Delphi 2010. In other words, this bug probably isn't a bug, until we hit Delphi 2010, which as one of its not-so-bright moves, changed how grid header click handling works. Introducing the breaking change "dgEditing" into Options. (It's on by default in all projects to which you add a DBGrid, but off whenever an existing Delphi 2009 or earlier project is imported.) A change that is {$ifdefd for delphi 2010} and higher is probably likely to be needed here. |
