IBO Controls should support the OnContextPopup Event.
It is just one line of code in IB_Control.pbl:

{$IFDEF IBO_VCL40_OR_GREATER}
property OnContextPopup;
{$ENDIF}

I add this property to support different popup menus in ib_grids,
depends on if an editor is active or not.
If the editor is not active it shows the popup menu of the grid.

Could this be added to the source?
