Dynamic ColumnInfo
I have a need to create a dynamic ColumnInfo for a listbrowser. I want to be able to add nodes in a loop like you would when adding to the listbrowser's items. The number of columns may vary. The order may vary, which is the biggest need for dynamic creation. create AllocLBColumnInfo() without specifying number of columns (or anything) create a new list for(;;) { allocate a new node fill in details add to list } attach list to ColumnInfo attach ColumnInfo to listbrowser Similar to how a Chooser list is created, too: 
  1. SelectByTypeChooserList=ChooserLabels(NULL);
  2. ChooserNode=IChooser->AllocChooserNode(
  3. 	CNA_Text,			SAK_LocaleString(MSG_DT_SYSTEM),
  4. TAG_DONE);
  5. SAK_AddChooserNode(SelectByTypeChooserList,ChooserNode,GLIST_BOTTOM);
  6. ChooserNode=IChooser->AllocChooserNode(
  7. 	CNA_Text,			SAK_LocaleString(MSG_DT_TEXT),
  8. TAG_DONE);
  9. SAK_AddChooserNode(SelectByTypeChooserList,ChooserNode,GLIST_BOTTOM);
  10. ChooserNode=IChooser->AllocChooserNode(
  11. 	CNA_Text,			SAK_LocaleString(MSG_DT_DOCUMENT),
  12. TAG_DONE);
  13. SAK_AddChooserNode(SelectByTypeChooserList,ChooserNode,GLIST_BOTTOM);

Re: Dynamic ColumnInfo
Create your own list of columns in a loop and after the loop count nodes and compose a tag list for AllocLBColumnInfoA.

Re: Dynamic ColumnInfo
I came up with: Count how many columns will be displayed. AllocLBColumnInfo(num) with an always stationary column filled in. Do my loop and use SetLBColumnInfoAttrs() and fill in each column's info. Then when start to fill in items: AllocListBrowserNode(num) with 2 global tags. Do my loop and use SetListBrowserNodeAttrs(node) to fill each column's data. I was hiding columns by setting width to 0, but the drag bar was not hidden so was getting thick (several next to each other).
