Hi!

Is it possible to get the Event-Number of the selected column of a ListIconGadget, if ChangeListIconGadgetDisplay is set to 3 (column mode)?

EventGadgetID() only returns the GadgetNumber.
What Function returns the selected column?

Best regards,
Martin

About sorting items by clicking at column head you should start with this tip from El_Choni.

To get the column index you need to work with the windows api:

Code: Select all

Structure NMLISTVIEW
  hdr.NMHDR
  iItem.l
  iSubItem.l
  uNewState.l
  uOldState.l
  uChanged.l
  ptAction.POINT
  lParam.l
EndStructure

;window callback
procedure wndproc(hwnd,msg,wparam,lparam)
shared hlv
ret=#PB_ProcessPureBasicEvents
  
  select msg
    
    case #WM_NOTIFY
      *pnmhdr.NMHDR=lparam
      if *pnmhdr\code=#LVN_COLUMNCLICK   ;column click
        *pnmlistview.NMLISTVIEW=lparam
        if *pnmlistview\hdr\hwndFrom=hlv ;comes from our listicon
          column=*pnmlistview\iSubItem
          messagerequester("",str(column),0)
        endif
      endif

  endselect
procedurereturn ret
endprocedure


hwnd=openwindow(0,100,100,300,150,#PB_Window_SystemMenu,"Column Click")
creategadgetlist(hwnd)

hlv=ListIconGadget(1,10,10,250,100,"Column 0",80)

AddGadgetColumn(1,1,"Column 1",80)
AddGadgetColumn(1,2,"Column 2",80)

setwindowcallback(@wndproc())

repeat
until waitwindowevent()=#PB_EventCloseWindow

Great !

Does anybody know, what code needs to be added to the callback
to get also the selected row information ?

(I want to determine which row, col in the Gadget was clicked by the User)

Thanks,
Mike

Look ad my example in the other thread

row=*pnmlistview\iItem

That's the row.
