In C that means something else. I understand that didactically would be
interesting but it is something that should be learned. Actually many
beginners will use the other form, the same as I did in the example you
sent me (see attached file also). Like this:
Ihandle* label = IupLabel(....
Ihandle* button = IupButton(...
Ihandle* gridbox = IupGridBox(label, button, NULL);
This is much easier than:
Ihandle* ctrls[3];
ctrls[0] = IupLabel(....
ctrls[1] = IupButton(...
ctrls[2] = NULL;
Ihandle* gridbox = IupGridBoxv(ctrls);
Best,
Scuri
