| Summary | 0006631: Drag and Drop | ||||
| Description | Drag and drop for the TjvDragDrop component will not work under Windows 10 unless the EXE is run as privileged user -AND- some extra code is run to enable messages to be passed correctly. See attached code unit below; Suggestion: add the code included below to JVCL so drag and drop functions correctly; Thanks; Bruce | ||||

Added property "AllowDropElevation: Boolean default False" to TJvDragDrop. By enabling it (Windows 7 and newer required) the "Drag" can come from an application with a lower privilege than the "Drop" window. |
