[Gmath-devel] GMatH News and Questions

[Hassan A. <au...@cr...>]

 Hi all,

 Well it's been a waiting period for GmatH. I am still waiting for a 
working gtkhtml widget and its python bindings. 

 The plan is to have html-based integrated help within each session. 
For instance yacas for now uses lynx to show help, I plan on making it 
use an internal gtkhtml widget to show it and show the contents of 
this help. Same thing with Numerical Python. 

 On another front I am still discovering all the facets of gtkplot. It 
really is cool as it allows for instance realtime plots among other 
things. I still don't know if it is possible to edit the plots on the 
fly for legends, labels and captions. 

 What I really want is to be able for instance to plot something, then 
edit the paper sheet where it is, add other plots (easy), write some 
text, etc.... Ideally it would be stripped down math-word processor 
where you can type some text add some formulas and such then print the 
sheet as an eps and insert it into your article, presentation ....

 Now comes the questions period. I am trying to implement among other 
things real-time plotting. You would create a function that returns a 
point/curve at given intervals and then the RTPlot command would take 
this as its arguments, and add the plot accordingly with proper 
identification. If you have points depending, it would just plot the 
thing and join the points if needed. If you are plotting curves that 
depend on time, then it would the curves in normal x,y coords and add 
a legend to each one, say time t=0, t=5, t=10 etc... Of course this 
has some limits, the number of colors you have on your system.

 Now comes the real questions:

 -Anyone knows how to get the rgb list of colors on your system, or 
the gnome strings associated with them?

 -Anyone knows what should happen if you wanted to interrupt the 
process for any reason?
 Would you want it to save its state, then maybe restart after 
corrections, dump everything, have the choices but then which choices? 
Any suggestions (reasonable) accepted!
