Updates to GUI files from Programming: Principles and Practice using C++ (Second Edition) using FLTK 1.3.6, Visual Studio 2019.
Put where your project file is.
Make sure to add the location of FLTK to your paths (header and libs). I didn't follow the book on putting in the VC directories. I just built FLTK and then added the paths.
For example: say I built FLTK in c:\source\FLTK-1.3.6. In VC++ Directories add the path as is for Included Directories. For Library Directories it would be c:\source\FLTK-1.3.6\lib
Under Linker-->Input add these to Additional Dependencies
- fltkd.lib
- fltkjpegd.lib
- fltkimagesd.lib
- comctl32.lib
- I took away some of the use of namespace in the files.
- Lot's of warnings. I chose not to correct as just for this course and any issues seem minor.
- In the code for the course, if puting Graph_lib into the namespace (using namespace Graph_lib), some types will still need Graph_lib (e.g., Ploygon will need Graph_lib::Polygon). VS will let you know. Since I don't use the using namespace.. I didn't work on this nusicance. I just use Graph_lib:: on everything, like:

int main()
{
Graph_lib::Point tl(100, 100); // to become top left corner of window
Graph_lib::Simple_window win(tl, 600, 400, "Canvas"); // make a simple window
Graph_lib::Polygon poly; // make a shape (a polygon)
poly.add(Graph_lib::Point(300, 200)); // add a point
poly.add(Graph_lib::Point(350, 100)); // add another point
poly.add(Graph_lib::Point(400, 200)); // add a third point
poly.set_color(Graph_lib::Color::red); // adjust properties of poly
win.attach(poly); // connect poly to the window
win.wait_for_button(); // give control to the display engine
}
