qt4-default 4:4.8.5+git192-g085f851+dfsg-2ubuntu4 (i386 binary) in ubuntu trusty

 Qt is a cross-platform C++ application framework. Qt's primary feature
 is its rich set of widgets that provide standard GUI functionality.
 .
 This package sets Qt 4 to be the default Qt version to be used when
 using development binaries like qmake. It provides a default
 configuration for qtchooser, but does not prevent alternative Qt
 installations from being used.
