EV_RICH_TEXT into EV_GRID

[Jimmy Johnson]

How do I put an EV_RICH_TEXT into an EV_GRID?

Items added to an EV_GRID must be of type EV_GRID_ITEM.

Can a class inherit from two EV_xxx classes (say EV_RICH_TEXT and EV_GRID_ITEM)?

If so, which implementation do I select?  etc.

thanks,

jjj

Hi Jimmy

Though I have never done such a thing, I suspect there might be some challenges but it might be possible.  Looking at the EV_GRID_ITEM family, it seems there are some descendants that have associated, albeit ephemeral, widgets.  These include EV_GRID_EDITABLE_ITEM with its associated text widget (EV_TEXT_FIELD) that appears as the result of an agent activation.  Conceivably, one could adapt that (i.e. create a child of it) to have an associated EV_RICH_TEXT widget.
