[king-gideon]

i need to design a dictionary in Qt.i have already done the interface but am having problems with the code.
What i want to do is this
Its a three language dictionary(can make it two)
when i type in a word in a linedit box and press translate, it shud bring out the translated word in the other boxes.I intend to save all the words in a file so i cn work with the words saved in the file but i dnt know how to go about this.I wud also appreciate other idaes on how to go about it.
