haskell - ComboBox doesn't show any of its strings -

-

i started using gtk2hs (gtk3 on hackage) , have run issues comboboxes. cannot make simple comboboxnewtext display strings. have commented out unneeded in application have basic framework actual box.

import graphics.ui.gtk import control.monad.io.class  main =   initgui   window <- windownew   set window [windowtitle := "table", containerborderwidth := 20,               windowdefaultwidth := 800, windowdefaultheight := 600]    table <- tablenew 10 10 true   containeradd window table    lbox <- hboxnew false 0   rbox <- hboxnew false 0   tableattachdefaults table lbox 0 3 0 10   tableattachdefaults table rbox 3 10 0 10    cb <- comboboxnewtext   comboboxappendtext cb "test"   boxpackstart lbox cb packgrow 10    on window deleteevent $ liftio mainquit >> return false   widgetshowall window   maingui

am missing something? gtk3 marked unstable iirc on hackage, bug? or doing incorrectly? adding comboboxsetactive cb 0 doesn't either. clarify, actual combobox appears when run program, doesn't contain strings/is blank. evernote image

as daniel wagner commented, seem bug in gtk3 package on hackage. fixed commit attached issue linked https://github.com/gtk2hs/gtk2hs/issues/10

i'm trying subclass qstyleditemdelegate remove focus rectangle in qcombobox . even though i'm calling base implementation of paint function , nothing else, result different. looks if parts of style-sheet influence bounding box of item taken consideration. class pstyleditemdelegate(qstyleditemdelegate): def __init__(self, *args, **kwds): super(pstyleditemdelegate, self).__init__(*args, **kwds) def paint(self, *args, **kwargs): qstyleditemdelegate.paint(*args, **kwargs) what have paint unmodified qstyleditemdelegate ? as suggested tried replacing pyside pyqt4 , works, appears bug. update pyside 1.1.2 1.2.1 result same. unfortunately switch breaks other parts of code, if there no other suggestions i'm going accept answer. edit bug tracked here
