我无法让imageTab
运行。我得到Segmentation fault: 11
。这是我的代码。有人知道该怎么办吗?
import Graphics.UI.WX
import Graphics.UI.WXCore
main :: IO ()
main = start gui
gui :: IO ()
gui = do
f <- frame []
fp <- panel f []
nb <- notebook fp []
page <- panel nb []
b <- button page [ text := "-"]
let bm = bitmap "favicon.ico"
-- check that bitmap is there
sx <- bitmapGetHeight bm
print sx
set f [ layout := container fp $ tabs nb [imageTab "Foo" bm (container page $ fill $ widget b)]]
-- This works
--set f [ layout := container fp $ tabs nb [tab "Foo" (container page $ fill $ widget b)]]
