I think we need this feature. I do not see anythign in the docs about it and a search of the threads has revealed NADA!!!

I am having to carry a FLAG with the number of columns currently in my single #ListIcon_THING

Is it possible?

Code: Select all

Procedure.l CountGadgetColumns(MyListIconGadget.l)
  ListIconGadgetHandle.l = SendMessage_(GadgetID(#MyListIconGadget), #LVM_GETHEADER, 0, 0)     ; Get collumn header
  numcols.l  = SendMessage_( ListIconGadgetHandle, #HDM_GETITEMCOUNT, 0, 0)                             ; Get number of collumns in header
	ProcedurReturn NumCols
EndProcedure

that's fine if you're happy relying on the API, but what about crossplatform?

No idea, but then, Rook didn't ask for a crossplatform solution. Instead of a separate flag, you could store the count in the item by using SetGadgetItemData(), it's in the manual.

Until the team see fit to add a native command.

Thats what i am asking for... a native command AND a fix of RemovegadgetColumn() as well!

Maybe we can expand the CountGadgetItems() command to a #Flag option where, when flag is set to #PB_Count_Columns is set, it returns the number of columns instead of items.
