Hello,
I want to set the text of a text entry while the program is running, but
wxWidgets/wxHaskell crashes with the following assertion failure:
../src/common/strinc.pp(410): assert "nStart <= length()" failed in erase()
Here a minimal program that crashes when you click the button:
import Graphics.UI.WX
main = start $ do
f <- frame [ text := "Test" ]
e <- entry f [ text := "A" ]
b <- button f [ text := "Button"
, on command := set e [ text := "B" ] ]
set f [ layout := row 5 [ widget b, widget e]]
Seems to be the same as this bug:
http://sourceforge.net/tracker/index.php?func=detail&aid=1826548&group_id=9863&atid=109863
Any workaround?
Best regards,
Heinrich Apfelmus
