PPP2_FLTK

Updates to GUI files from Programming: Principles and Practice using C++ (Second Edition) using FLTK 1.3.6, Visual Studio 2019.

Usage

Put where your project file is.

VS Settings

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

Odds and Ends

1. I took away some of the use of namespace in the files.
2. Lot'south of warnings. I chose not to correct as just for this course and any issues seem minor.
3. In the code for the course, if puting Graph_lib into the namespace (using namespace Graph_lib), some types will still need Graph_lib (east.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:

// This is example code from Chapter 12.3 "A first example" of
// "Programming -- Principles and Practice Using C++" by Bjarne Stroustrup
//

#include "Simple_window.h"    // get access to our window library
#include "Graph.h"            // get access to our graphics library facilities

//------------------------------------------------------------------------------

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
}
