Problem in Line Editor in Qt?

Question

Hi all,

I am trying to set the text of line editor in Qt on linux. It works for all but 2 line editors which for some strange reason don't display the text even when we set the text using

mValueLineEdit->setText("Hello")

I have debugged each and every line of code in my application but nothing fishy was found.I checked after setting the text using text() and displayText() properties also but no luck.
