  1. struct Node *node;

@thomas Using

@thomas

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

  1. struct Node *node = NULL;
  2. GetAttr (CHOOSER_SelectedNode,object,(Tag *)&node);
  3. if (node) {
  4. char *label = NULL;
  5. GetChooserNodeAttrs (node,CNA_Text,&label,TAG_END);
  6. if (label)
  7. Printf ("%s\n",label);
  8. }

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.

  1. struct Node *node = NULL;
  2. if (ChooserBase->lib_Version > 52 ||
  3. (ChooserBase->lib_Version == 52 &&
  4. ChooserBase->lib_Revision >= 5))
  5. {
  6. GetAttr (CHOOSER_SelectedNode,object,(uint32 *)&node);
  7. } else {
  8. uint32 which = 0;
  9. GetAttr (CHOOSER_Selected,object,&which);
  10. for (node = GetHead(labels); node; node = GetSucc(node)) {
  11. if (which == 0) break;
  12. which--;
  13. }
  14. }
  15. if (node) {
  16. char *label = NULL;
  17. GetChooserNodeAttrs (node,CNA_Text,&label,TAG_END);
  18. if (label) Printf ("%s\n",label);
  19. }
