Home away from home

When i add nodes to a struct list, all goes well and the new node is added at the end of the list. But now i'm trying to add a node in the middle or at the beginning of the list, and no matter what i try it always goes at the end. Anyone here good at this thing? some code is at the bottom so people can see what i do.


SetGadgetAttrs(gadgets[GID_LISTVIEW], windows[WID_MAIN], NULL,LISTBROWSER_Labels, ~0,TAG_DONE); 

node = (struct Node *)AllocListBrowserNode(4,

                    LBNA_Column, 0,

                    LBNCA_CopyText, TRUE,

                    LBNCA_Text,tall,

                    LBNA_Column, 1,

                    LBNCA_CopyText, TRUE,

                    LBNCA_MaxChars, 255,

                    LBNCA_Text,test,

                    LBNA_Column, 2,

                    LBNCA_CopyText, TRUE,

                    LBNCA_Text,type,

                    LBNCA_Justification, LCJ_CENTRE,

                    LBNA_Column, 3,

                    LBNCA_CopyText, TRUE,

                    LBNCA_Text,text,

                TAG_DONE); 

             AddTail( &liste, node); 

RefreshSetGadgetAttrs(gadgets[GID_LISTVIEW], windows[WID_MAIN], NULL,LISTBROWSER_Labels,&liste ,TAG_DONE);

@Antique

You are using AddTail, which automatically adds the node to the end of the list. You should use

void Insert(struct List *l, struct Node *node, struct Node *nodeToFollow);

...which adds "node" to the list right after "nodeToFollow".

There's also the AddHead function which is like AddTail but adds to the beginning of the list.
