Virtual String Tree 4.8.7 HeaderDblClick Event without function?

I just tried to use the event OnHeaderDblClick of the VirtualStringTree Component (Version 4.8.7) Is it possible, that this event is not working?

Or is there some option that I need to set to get it to work?

Solution

  • You're right, it cannot work. Mike forgot to call the TBaseVirtualTree.DoHeaderDblClick what fires the OnHeaderDblClick in VirtualTreeView version 4.8.7.

    It is fixed in VirtualTreeView version 5.0.0 as ain mentioned in TVirtualTreeColumns.HandleClick method.
