For example,
$ grep -r '^#include <q' filelight-0.6.4.1/src/
filelight-0.6.4.1/src/segmenttip.h:#include <qwidget.h>
filelight-0.6.4.1/src/segmenttip.h:#include <qpixmap.h>
filelight-0.6.4.1/src/filemap.cpp:#include <qapplication.h> //make()
filelight-0.6.4.1/src/filemap.cpp:#include <qpainter.h>
filelight-0.6.4.1/src/filemap.cpp:#include <qimage.h> //make() & paint()
filelight-0.6.4.1/src/filemap.cpp:#include <qfont.h>
filelight-0.6.4.1/src/filemap.cpp:#include <qfontmetrics.h>
