Hi, I want to know how to use the resources Pt_ARG_LIST_ITEMS and Pt_ARG_SELECTED_INDEXES to know wich element is selected in a PtList, and how to get the text of that items.

thanks.

the resources is Pt_ARG_LIST
the resources Pt_ARG_LIST_ITEMS no exist

//To Load a PtList Widget:

void LoadPlist (void)
{

char buf[200];
char *punt;

punt = buf;

//Pasa a buf los datos  a mostrar
sprintf (buf, "MI MAMA ME MIMA");

//Carga en la lista lo que esta en buf (punt apunta a buf)
PtListAddItems (ABW_Lista, (const char **)&punt, 1, 0);

}

//To Delete ALL ITEMS in PtList
PtListDeleteAllItems (ABW_Lista);

Gracias, me sirve, pero lo que me interesa saber es, una vez que ya tengo cargado el PtList, cómo hago para saber que elemento esta seleccionado y cómo obtengo el texto del elemento seleccionado.

gracias.

Somting like this

In PtLIst widget add callback type Pt_CB_SELECTION on function fun(…)

fun(…)
{
unsigned short index;
char *item_text, **item_mas;
PtGetResource(list_wgt, Pt_ARG_SELECTION_INDEXES, index, 1)
PtSetArg(&arg, Pt_ARG_ITEMS, item_mas, 0);
PtGetResources(list_wgt, 1, &arg)

item_text = item_mas[index-1]; — frst item have number 1
}
