So, I'd like to know if anyone here have any practical experience with programming as a teaching tool? Yes, I have a lot. Numerical and symbolic calculations help to introduce difficult concepts fast and on a practical level. But don't start with programing. Use Maxima (with wxMaxima GUI). It is fr...

Who said Dislin must be included? It is enough to include examples. And how are they supposed to work, without the library? Apparently, you do not understand what I am talking about, because of my bad English. Let me repeat, this library exists. Short instruction on downloading and installing may b...

It is a close source project but it is free for non-commercial use. So, it is completely useless for our purpose. Without source, it can't be adapted or updated. And a license that is free only for non commercial use would not allow to include it in FreeBasic, or in any software developed with it (...

Where is the source? And what license does it use? It is a close source project but it is free for non-commercial use. Furthermore, Freebasic is supported and I find Widget Routines quite useful. IMHO its existence strengthen the position of FB. I wonder if somebody here use FB + Dislin on Linux.

So, the best solution would be to write a default library, that on windows wraps the default GUI, and on Linux offers interface for both GTK and Qt, always using the same syntax Paraphrasing Lenin's words: "There is such GUI !". It is included as "Widget Routines" in Dislin libr...

So, you know coordinates of the vertices? Why not calculate the area directly?
As far as I remember, it is quite easy for not self-intersecting polygons

Weakness:
The Battleship FreeBasic is tugged to her last berth to be broken up in the harbour of abandonware.
Salvation:
Windows fork, maintained by gentle people who are refugees from the Raft of the PowerBasic

1. All we need are tutorials on GUI programming. Sure? But what do you do with a GUI without any content? You missed the point, the problem is what to do with lot of content without any simple GUI. @deltarho How many pages have the book of Petzold? Is it written with a tutorial for beginners style?...

As a mathusalemic newbe and beginner forever I would like to state the following: 1. All we need are tutorials on GUI programming. 2. Very good example is Introduction to GUI Programming with FLTK by Lothar Schirm (step by step introduction of widgets, clean and elegant coding style,...). 3. Shared ...

Mr_Swiss did, but never mind. I am impressed by your achievements
and I am going to learn more about fltk-c.

Ah, I see. Function like e.g. Fl_BoxNew () is invented by Mr Peters
and defined in his fltk-c library, which is at the moment compiled for windows only.
Confusion will be my epitaph...

the code generated, will still be Windows only ... (no multiplatform). Yes I know and after Paul's declaration the discussion is purely academic, but imagine hypothetical Designer which contains JDPeters FLTK library (in a similar way as WinFBE contains library of Jose Roca). Generated program code...

It is slightly off-topic but let me make a very faint
suggestion for Paul. It would be nice if his new Designer has a "lite"
version which emits very basic FLTK code. It will give a scent
of cross-platforming...

Jose Roca continues to produce great new code for FreeBASIC Windows. Check out the help resource at http://www.jose.it-berater.org/CWindow/CWindowFramework.html and get the code from http://www.planetsquires.com/protect/forum/index.php?topic=4061.0 Paul, Can you provide a simple example of CWindow ...

Plus there are lots of people using freeBASIC for scientific modeling... I am an experimental physicist and I use FB for almost everything, from data acquisition to modelling and numerical calculations. I had used Matlab, LabView etc., however, it turned out that I am much more productive with Free...
