# The QT variable controls what modules are included in compilation.
# Note that the 'core' and 'gui' modules are included by default.
# For widget-based GUI applications, the 'widgets' module needs to be added.
QT += widgets
HEADERS = Window.h # Everything added to the HEADER variable will be checked
# to see if moc needs to run on it, and it will be run if
# so.
SOURCES = main.cpp # Everything added to the SOURCES variable will be compiled
# and (in the simple example) added to the resulting
# executable.
Command Line
# Assuming you are in a folder that contains the above files.
> qmake # You can also add the example.pro file if needed
> make # qmake creates a Makefile, this runs make on it.
> ./example # The name of the executable defaults to the .pro file name.
