Hi Kendall,

You need to set the flag  Pt_GROUP_NO_SELECT_ALLOWED  on the PtGroup widget.

Cheers,
Thomas

Betreff: Re: Setting a PtToggleButton that is part of a group

I have found a "work-around", but I hope there is a better, more direct way to accomplish this.

What I am currently doing is:

1. Calling PtGetResource() to determine if the exclusivity bit is set for the group.
2. If so, call PtSetResource() to turn the exclusivity off for the group.
3. Call PtSetResource() for the specific toggle button widget to clear it.
4. Call PtSetResource() for the group to turn exclusivity back on.

[CODE]
int clear(PtWidget_t* pWidget, PtWidget_t* pGroupWidget)
{ 
    short* pnBitVal = 0;
    char    bExclusiveBitSet = 0;

    //DETERMINE STATUS OF EXCLUSIVITY BIT
    PtGetResource(pGroupWidget, Pt_ARG_GROUP_FLAGS, &pnBitVal, Pt_GROUP_EXCLUSIVE);

    //STORE STATUS
    bExclusiveBitSet = (*pnBitVal) ? 1 : 0;
    
    //TURN OFF EXCLUSIVITY IF IT IS ON
    if(bExclusiveBitSet)
    {
        PtSetResource(pGroupWidget, Pt_ARG_GROUP_FLAGS, ~Pt_GROUP_EXCLUSIVE, Pt_GROUP_EXCLUSIVE);
    }

    //CLEAR Pt_SET FROM WIDGET
    PtSetResource(pWidget, Pt_ARG_FLAGS, ~Pt_SET, Pt_SET);

    //TURN EXCLUSIVITY BACK ON IF NECESSARY
    if(bExclusiveBitSet)
    {
        PtSetResource(pGroupWidget, Pt_ARG_GROUP_FLAGS, Pt_GROUP_EXCLUSIVE, Pt_GROUP_EXCLUSIVE);
    }

    return 0;
}
[/CODE]


Is there an easier or more direct way to do this?

Thanks,
Kendall
