Gtk提供的基本ComboBox只能处理String或Pixbuf。
但我想要一张文本和一张图片在同一行选择的附近。
我花了一段时间研究如何使用Haskell和Gtk2Hs获得以下结果。

下面是获得预期结果的代码:
pic1 <- pixbufNewFromFile "Picture_1.png"
pic2 <- pixbufNewFromFile "Picture_2.png"
pic3 <- pixbufNewFromFile "Picture_3.png"
let lstsecrep = [
("Picture 1",pic1)
, ("Picture 2",pic2)
, ("Picture 3",pic3)
]
lststorerep <- listStoreNew lstsecrep
customStoreSetColumn lststorerep (makeColumnIdString 0) fst
customStoreSetColumn lststorerep (makeColumnIdPixbuf 1) snd
combo <- comboBoxNewWithModel lststorerep
rendertxt <- cellRendererTextNew
renderpic <- cellRendererPixbufNew
cellLayoutPackStart combo rendertxt False
cellLayoutPackStart combo renderpic True
cellLayoutAddColumnAttribute combo rendertxt cellText $ makeColumnIdString 0
cellLayoutAddColumnAttribute combo renderpic cellPixbuf $ makeColumnIdPixbuf 1诚挚的问候。
