Re: Using FreeBASIC in the classroom?

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...

Re: Part 3 Action "the GUI library"

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...

Re: Part 3 Action "the GUI library"

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 (...

Re: Part 3 Action "the GUI library"

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.

Re: Part 3 Action "the GUI library"

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...

Re: Point in a polygon

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

Re: How to write tutorials for beginners ?

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?...

Re: How to write tutorials for beginners ?

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 ...

Re: exemple buttons and msgbox

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...
