Small Addition:
If you are on Windows

Code: Select all

 
; Windows Only Code as an addition to the above code 
Macro SetListIconGadgetNoHorzScrollbar(Gadget)
  SendMessage_(GadgetID(Gadget), #LVM_SETCOLUMNWIDTH, 0, #LVSCW_AUTOSIZE_USEHEADER)
  ShowScrollBar_(GadgetID(Gadget), #SB_HORZ, #False) 
EndMacro

Macro SetListIconGadgetNoHeader(Gadget) 
  SetWindowLongPtr_(GadgetID(Gadget), #GWL_STYLE, GetWindowLongPtr_(GadgetID(Gadget), #GWL_STYLE)|#LVS_NOCOLUMNHEADER) 
EndMacro 

; ... behind this line: 
; ListIconGadget(#MainTraceList, 0, 0, dx, dy, "Messages", dy-24, #PB_ListIcon_FullRowSelect)
; add here to have the same look as ListViewGadget  
SetListIconGadgetNoHeader(#MainTraceList) 
SetListIconGadgetNoHorzScrollbar(#MainTraceList)

Can you add in future versions the function of scrolling the editor gadget to the end for Linux?
