| Summary | 0005544: JvDockSupportControl.pas, BCB6 (D6), Docking and Access Violation (AV) | ||||
| Description | I found out problem which is related to BCB6 and D6 in all probability (I don't know whether D6 do this as well). I have problem with dockable forms: 1. If I want to move non-docked form on my screen it shows an AV (Access Violation) message. No docking is required here. 2. If I want to undock actually docked form (to be floating) it also shows the AV message. I decided to compare older versions of the JvDockSupportControl.pas and I found there difference in a "DoFloatForm(Control: TControl)" procedure which is inserted into a "DragDone(Drop: Boolean)" procedure where is called a "DragObject.AlphaBlendedForm.Hide" procedure. I decided to disable this line for BCB6 in the end. See conditional compilation example below. When I done it the Float Form AV disappeared. Conditional compilation : ... {$IFDEF COMPILER7_UP} DragObject.AlphaBlendedForm.Hide; {$ENDIF !COMPILER7_UP} | ||||
| Additional Information | Example is not need because standard JVCL example named "DockOptionDemo" which is also translated to C++ generates AV as well. I also checked "DockOptionDemo" under BDS2006 (C++ and Delphi) and under RAD Studio 2010 as well and there is not such strange behaviour of the demo. This problem is related to issue: http://issuetracker.delphi-jedi.org/view.php?id=5297 which sold "JvDocking Floating form not drawing correctly " but the BCB6 was not tested in all probability. ;-) | ||||
