| Summary | 0003131: TJvDBGrid handles OnKeyPress event twice | ||||
| Description | A TJvDBGrid handles an OnKeyPress() event twice. One time correctly, one time with var Key equal to #0. This problem occurs after updating to version 3. | ||||
| Steps To Reproduce | Click New > Application. Drop a TJvDBGrid on the form. In the OnKeyPress event procedure of the JvDBGrid write: begin ShowMessage(IntToStr(Ord(Key))); end; Run the application and press a key. Everything seems to work correctly. Now press the Enter key. Two values are showed: 13 (correct) and 0 (incorrect). In my real application, the OnKeyPress() event is *always* fired twice. So, when I press the '8' key, it is one time fired with Key = '8' and one time with Key = #0. | ||||

Could not reproduce with D7E/W2K using updated jcl/jvcl from cvs 2005/08/17. Tested with simple "Showmessage(Key)" in event handler - only the actual key pressed is displayed. Does this occur in a simple test case? EdB |

I tried to reduce the number of KeyPressed event triggers as much as it was possible. I can't do better. In most cases, you'll have only one KeyPressed event fired. Verify that your JVCL files are up-to-date. Fred |
