| Summary | 0005297: JvDocking Floating form not drawing correctly | ||||
| Description | Docking style VSNet When I drag form from a docked state to a floating state *sometimes* it is not painted correctly. | ||||
| Additional Information | Fix: In JvDockSupportForm procedure DoFloatForm insert one line: procedure DoFloatForm(Control: TControl); var WasVisible: Boolean; begin if Control.FloatingDockSiteClass = Control.ClassType then begin WasVisible := Control.Visible; try DragObject.AlphaBlendedForm.Hide; // line inserted Control.Dock(nil, DragObject.DockRect); if (Control.Left <> DragObject.DockRect.Left) or (Control.Top <> DragObject.DockRect.Top) then begin Control.Left := DragObject.DockRect.Left; Control.Top := DragObject.DockRect.Top; end; finally if WasVisible then Control.BringToFront; end; end; end; This extra line hides the alpha blended form before showing the floating form. Also while we are at it there is absolutely no reason for TJvAlphaBlendedForm to inherit from TJvForm. | ||||

I had this problem with PyScripter (sources at pyscripter.googlecode.com) and it would be hard to reproduce in a simple example. However, if you see what the change is doing it is hiding the AlphaBlended form used while dragging forms, before making visible the dragged form. This is good practice anyway and cannot do any harm. In the problem I had, when the AlphaBlended form was hidden/destroyed it messed up the appearance of the already shown dragged form for some unknown reason. By the way I am the contributor of the AlphaBlended stuff. |

Actually the problem is reproducible with the DockingInCode JvDocking demo in Windows 7. - Run the demo. - Press the Conjoined dock button. - Drag a form to a floating position. The form is not painted properly. |

Someone with Win7 will have to look at this, provided it is not already fixed in SVN |
