Group Menu In Replace Mode?

[sibarrick]

Hi,

How do you make a group menu choicelist replace and not append?

That is I have a string parameter that has a choice menu that lets you pick named prim groups, but it seems to default to the normal append type, where each time you pick a group from the dropdown it adds it to the field. I want to just make it replace so you can only pick one group name at a time.

So this is what I have at the moment

    PRM_Template((PRM_Type)(PRM_STRING|PRM_TYPE_LABEL_NONE),    1, &names[5], 0, &SOP_Node::primNamedGroupMenu),

Any ideas how to modify this to make it replace?

There is a PRM_ChoiceListType called PRM_CHOICELIST_REPLACE but I'm not sure how to combine it with the group menu type which is defined in the SOP_Node class as

static PRM_ChoiceList  primNamedGroupMenu;

I think you need to build your own PRM_ChoiceList then to use PRM_CHOICELIST_REPLACE ... something like ...

#define         POINT_GROUP             0x01
#define         PRIM_GROUP              0x02
#define         BOTH_GROUPS             0x03    
#define         EDGE_GROUP              0x04
#define         BREAKPOINT_GROUP        0x08

static void
buildNamedPrimGroup(void *data, PRM_Name *menuEntries, int thelistsize,
                     const PRM_SpareData *spare, PRM_Parm *parm)
{
    SOP_Node    *sop;
    int          value;

    sop   = CAST_SOPNODE((OP_Node *)data);
    if (sop)
    {
        sop->buildInputGroups(0, menuEntries, thelistsize, PRIM_GROUP, 0, false, parm);
    }
    else
    {
        menuEntries[0].setToken(0);
        menuEntries[0].setLabel(0);
    }
}

static PRM_ChoiceList thePrimChoiceList(PRM_CHOICELIST_REPLACE,buildNamedPrimGroup);

Cheers Edward. I thought it would be something simply There's no way i'd have figured that out for myself. Many thanks.
