示例1: py_get_colorlist
static PyObject* py_get_colorlist(PyObject *self, PyObject *args)
{
PyObject *newlist = NULL, *newtuple = NULL;
int i, j, listlen;
const char *name;
float col[3];
VMDApp *app;
if (!(app = get_vmdapp()))
return NULL;
listlen = app->num_regular_colors();
if (!(newlist = PyList_New(listlen)))
goto failure;
for (i = 0; i < listlen; i++) {
name = app->color_name(i);
if (!app->color_value(name, col, col+1, col+2))
goto failure;
if (!(newtuple = PyTuple_New(3)))
goto failure;
for (j = 0; j < 3; j++) {
PyTuple_SET_ITEM(newtuple, j, PyFloat_FromDouble(col[j]));
if (PyErr_Occurred())
goto failure;
}
PyList_SET_ITEM(newlist, i, newtuple);
if (PyErr_Occurred())
