ListviewGrid

[thalesduarte]

It's possible to change grid color from listview in ahk v2?

Thanks!

It seems impossible.

Code: Select all

Gui1 := Gui()
Lv1 := Gui1.Add("ListView", "w400 h300 BackgroundE1BEE7 +Multi Grid Checked", [, "Items"])
SetListViewHeaderCheckBox(Lv1)
Lv1.OnNotify(-316, HDN_ITEMSTATEICONCLICK)
Loop 10
	Lv1.Add(,, "Item " A_Index)

Gui1.BackColor  := 'EEAA99'
For Hwnd, GuiCtrlObj in Gui1{
       DllCall("uxtheme\SetWindowTheme", "ptr", GuiCtrlObj.hwnd, "str", "DarkMode_Explorer", "ptr", 0)
}

Gui1.Show()
Return

HDN_ITEMSTATEICONCLICK(Ctrl, L) {
   Static OffFmt := (4 * 3) + (A_PtrSize * 2)
   HHDR := NumGet(L, "UPtr")
   Item := NumGet(L, A_PtrSize * 3, "Int")
   HDITEM := NumGet(L, 8 + (A_PtrSize * 3), "UPtr")
   Fmt := NumGet(HDITEM, OffFmt, "Int")
   ; >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
   ToolTip(Fmt & 0x0080 ? "Uncheck!" : "Check!") ; HDF_CHECKED = 0x0080
   ; <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
   NumPut("Int", Fmt ^ 0x0080, HDITEM, OffFmt) ; toggle the 'checked' state
   SendMessage(0x120C, Item, HDITEM, HHDR) ; HDM_SETITEM = 0x120C
   Return 1 ; prevent normal notification processing
}
