[英]How to get the newly selected page index upon a notebook changed page event with wxHaskell?
[英]wxhaskell notebook with imageTag segfaults
我只是無法運行imageTab
。 我遇到了Segmentation fault: 11
。 這是我的代碼。 有人知道該怎么辦嗎?
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)]]
這看起來像個錯誤; 您最好在http://sourceforge.net/p/wxhaskell/bugs/報告
