[Qt-creator] Unable to write composed characters

[Nikos Chantziaras]

I am unable to write composed characters in Qt Creator.  For example, 
when I want to write:

   á

In all other programs I press these two keys in succession:

   'a

That gets me an "á".  But in Qt Creator that doesn't work.  As soon as I 
press the ' key, it immediately appears on screen.  So instead of "á", I 
get "'a".  Is there a setting I'm missing?  If there is, I'm unable to 
find it.
