source code for a simple example demonstrating how to access the PLplot API
from a Qt GUI application.
For all our build systems (cmake in the build tree, cmake in the
installed examples build tree, and the traditional pkg-config+Makefile
build system for the installed examples tree), you build this simple
Qt example (with all dependencies taken care of automatically) by
running
make qt_example
For our two CMake-based build systems you can run this example (with
all dependencies taken care of automatically) by running
make test_qt_example
