Hi
Sorry that it took so long.
Basicaly the idea of the program is nice. But IMHO the code needs quite some more \
work/love. I think this comes from porting the old program to c++/qt, so there is \
still old code in it. I hope i don't discourage you by that many positions. I didn't \
check everithing but i think you get the idea.
My english is pretty bad, so if something isn't clear ask.

No variable should be public. Make them private.
If another class needs that value, make a function to get or set the value. That way \
you have a nice api. Also indicate with a prefix (m_) that those varaibles are \
members of that class.

void titrationCalculator::plot()
the plot function does far more then plot.
Trying to split it in i.e dataGathering, axis, calculation, formating output or so, \
might help reading and maintain the code. For instantce, it's hard to find out where \
the actual calculation takes place.
If you really need it i can do it, but it will make the code really confuse, because \
the plot drawing is done in different steps and they depend from the result of the \
previous step.

QImage image(width, height, QImage::Format_Indexed8);
Why do you use the QImage class for the plot? QGraphicsView or kplot would imho have \
much more comfort. Check also the code from the other kdeedu plot programs to see how \
they do it. To generate an image (pixmap in this case) you can always do
pix = QPixmap::grabWidget(m_myPlotWidget);
Well, the plot is not very interesting... I added it just because it seems ugly to me \
an analitic program that doesn't show the result in a graphical way. The only \
interesting informations came from the notes box. The plot gives just an idea of what \
you have found, but in a laboratory relation you don't need it. Anyway, I could use \
kplot, if you want.

I am not sure if that method eats unnessery RAM. Acessing the tableWidget directly \

do you realy need to convert the QString to char? (QList?)
Yes because I need to read one character at a time, QList make things more complex.

Use QString() insteat of "".

Thats the second thime you do this.
Makeing a function that gets the data from tableWidget and put it in a QList of some \
sort would make the code cleaner. It's another table. Anyway I settled it up.

QMessageBox::information(this, "IceeQt Rapid Help", "There are two ways to \
use IceeQt:\n\nTheorical Equations\n Here you can fill the table with the equations \
you have previously obtained for the chemical equilibria. FOR EXAMPLE if you have \
this reaction A + B -> C + D then you will have the equation K=(C*D)/(A*B) so you \
must write 'K' in the Parameter column and '(C*D)/(A*B)' in the Value column. If you \
want to assign a known value to a parameter you can simply write the numeric value in \
the Value field. FOR EXAMPLE you can use the system \nA=(C*D)/(B*K) \nK=10^-3 \nC=OH \
\nOH=(10^-14)/H \nH=10^-4 \nB=6*(10^-2) \nThen you have to write D as X axis and A as \
Y axis: so you will find out how the concentration of A change in function of D \
concentration.\nPlease don't use parenthesis for exponents: 10^-3 is correct, while \
10^(-3) is wrong. \n\nExperimental Values\n You can use this program to draw the plot \
of your experimental data obtained during a titration and find out the volume of \
equivalence. It's strongly recommended to insert a even number of points, because of \
the best fit algorithm, sorted by volume (the X axis value).\n\nPlot\n The plot shows \
in red the curve that cames from theorical equations, in blue the experimental \
points, and in green the aproximated curve for experimental points.");
Adding a html (or somthing else) file somewhere and loading it here would be nice. \
that way the help can be edited without changing the source code.
I decided to remove it... its' better to include this text into the kalzium guide.

some default values would help understand the programm. if everthing is empty it's \
not easy to "just" try the program out.
I included it into the "Example" button code so it fills the tables with the example \

</div> If you really need it i can do it, but it will make the code really confuse, \
because the plot drawing is done in different steps and they depend from the result \

use the QImage class for the plot? QGraphicsView or kplot would imho have much more \
comfort. Check also the code from the other kdeedu plot programs to see how they do \
it. To generate an image (pixmap in this case) you can always do
pix = QPixmap::grabWidget(m_myPlotWidget);
</pre>
</div>
Well, the plot is not very interesting... I added it just because it seems ugly to me \
an analitic program that doesn't show the result in a graphical way. The only \
interesting informations came from the notes box. The plot gives just an idea of what \
you have found, but in a laboratory relation you don't need it. Anyway, I could use \
kplot, if you want.<br>
