struct Node *node;ULONG which

struct Node *node;
ULONG which = 0;
GetAttr (CHOOSER_Selected,object,&which);
for (node = GetHead(labels); node; node = GetSucc(node))
	{
	if (which == 0)
		break;
	which --;
	}
if (node)
	{
	char *label = NULL;
	GetChooserNodeAttrs (node,CNA_Text,&label,TAG_END);
	if (label)
		Printf ("%s\n",label);
	}

@thomas Using

@thomas

Using CHOOSER_SelectedNode (available in chooser.gadget >= 52.5) your code can be shortened to:

struct Node *node = NULL;
GetAttr (CHOOSER_SelectedNode,object,(Tag *)&node);
if (node) {
	char *label = NULL;
	GetChooserNodeAttrs (node,CNA_Text,&label,TAG_END);
	if (label)
		Printf ("%s\n",label);
}

I thought so, but it's not mentioned in 3.9 autodocs ;-)

Thanks guys, I will fix my code.
One of my goals is to keep my software as much compatible as possible, say AOS 4.0 as a minimum requirement.
52.0 means AOS 4.0, right?

@thomas Why don't you have

@thomas

Why don't you have 4.1 autodocs? They're in the SDK which is free to download from hyperion-entertainment.biz...

@Massi

Version numbers 50-52 are AmigaOS 4.0, version 53 is AmigaOS4.1.

If backwards compatibility is a big deal for you, you can always add a version check and use thomas' version if it's too old.

struct Node *node = NULL;
if (ChooserBase->lib_Version > 52 ||
    (ChooserBase->lib_Version == 52 &&
    ChooserBase->lib_Revision >= 5))
{
    GetAttr (CHOOSER_SelectedNode,object,(uint32 *)&node);
} else {
    uint32 which = 0;
    GetAttr (CHOOSER_Selected,object,&which);
    for (node = GetHead(labels); node; node = GetSucc(node)) {
        if (which == 0) break;
        which--;
    }
}
if (node) {
    char *label = NULL;
    GetChooserNodeAttrs (node,CNA_Text,&label,TAG_END);
    if (label) Printf ("%s\n",label);
}
