How do you block and unblock individual widgets?  

I am attempting to block and unblock (disable and enable) individual widgets depending upon the state of the overall 
program and what the user is trying to do.

PtSetResource() is not working for this or I am not calling it correctly.  I can successfully get the resource with 
PtGetResource().

Right now I am just trying to do this with PtText widgets, but I will soon need to do this with other types as well.

Basically, my code is currently doing the following:

PtGetResource(pWidget, Pt_ARG_FLAGS, &pnGetFlags, 0);
nSetFlags = *pnGetFlags | Pt_BLOCKED;
PtSetResource(pWidget, Pt_ARG_FLAGS, nSetFlags, 0);

//I have also tried the following modifications to PtSetResource
PtSetResource(pWidget, Pt_ARG_FLAGS, nSetFlags, 4);
PtSetResource(pWidget, Pt_ARG_FLAGS, nSetFlags, sizeof(long));


The code for the full functions are included below:

#include <Pt.h>

int WdgtDisable(PtWidget_t* pWidget)
{
    int nError = 0;

    if(PtWidgetClass(pWidget) == PtText)
    {
        unsigned long* pnGetFlags = 0;
        unsigned long  nSetFlags = 0;

        /* GET WIDGET FLAGS */
        PtGetResource(pWidget, Pt_ARG_FLAGS, &pnGetFlags, 0);
        /* SET BLOCK FLAG */
        nSetFlags = *pnGetFlags | Pt_BLOCKED;
        nError = PtSetResource(pWidget, Pt_ARG_FLAGS, nSetFlags, 4);
        /* SET COLOR TO INDICATE WIDGET IS BLOCKED */
        PtSetResource(pWidget, Pt_ARG_FILL_COLOR, PgGray(217), 0);
    }

    return nError;
}

int WdgtEnable(PtWidget_t* pWidget)
{
    int nError = 0;

    if(PtWidgetClass(pWidget) == PtText)
    {
        unsigned long* pnGetFlags = 0;
        unsigned long  nSetFlags  = 0;

        /* GET WIDGET FLAGS */
        PtGetResource(pWidget, Pt_ARG_FLAGS, &pnGetFlags, 0);
        /* UNSET BLOCK FLAG */
        nSetFlags = *pnGetFlags & ~Pt_BLOCKED;
        nError = PtSetResource(pWidget, Pt_ARG_FLAGS, nSetFlags, 4);
        /*SET COLOR TO INDICATE WIDGET IS UNBLOCKED*/
        PtSetResource(pWidget, Pt_ARG_FILL_COLOR, PgGray(254), 0);
    }

    return nError;
}
