pdfGetOutlineChild

Get an outline node child.
PDFOutlineHandle pdfGetOutlineChild(PDFViewerHandle viewer, PDFOutlineHandle outline, int idx)
This function returns the idxth child of the specified outline tree node. idx must be between 0 and n-1, where n is the value returned by pdfGetOutlineNumChildren.

Pass NULL as the outline argument to specify the root node, i.e., to get the top-level outline entries.

C:
/* start out at the root node */ scanOutline(NULL); ... void scanOutline(PDFOutlineHandle outline) { int n, i; if (outline) { /* do something with this outline entry */ } else { /* this is the root node, which isn't a real entry - * it has no title or target */ } /* now scan the children of this node (if any) */ n = pdfGetOutlineNumChildren(viewer, outline); for (i = 0; i < n; ++i) { scanOutline(pdfGetOutlineChild(viewer, outline, i)); } }
