I'm developing a scientific calculator but I have some problem with the symbol.
For example I found the code for drawing raise to second (\262) and thrid (\263).
But I need the code for representing the symbols of:
- cube root
- greek pi
- ^ -1
- subscript a
Thanks to everybody.
Maybe, it'll be better if you will render the symbols as images.
This symbol are represent in a push button. How can I insert the image on the button?
http://www.unicode.org/charts/ has charts with all the symbols defined by unicode. Qt handles unicode, so any of them works, provided your font contains the symbol.
One way to get an image on your button, is to use QToolButton instead of QPushButton. You can use a QAction to represent the operation (root, cube root, etc.) or constant (pi, e, etc.). You can associate an image with a QAction, and it will be rendered on your tool button automatically.
I've got some fonts which has this especial function (mathematical fonts) ... Images (for me) aren't good solution, but in any way you will need to do a lot of positioning (indexes, powers of number, roots, sums, prods, and so on...)
I think a great library of fonts (but with fees: http://new.myfonts.com/search/tag:math/fonts/)
MS Word (2007+) uses this font: http://www.microsoft.com/typography/fonts/family.aspx?FID=360

What are you talking about? Positioning? How? What kind of positioning do you think needs doing if you just want to put it on a button?
Example: If you have a small index under function how you can get it there?
On button? No. I mean on a "paper". It will be clickable as in Word 2003 (MS Equation 3.0) ?
It's quite a lot of work, but I hope it will come out. :)
That is a different issue, Peppy. You are confusion the discussion. The topic starter was after buttons:

It is for that purpose that I suggest to use images. If you want to create editable formulas in some kind of editor, you are dealing with quite another topic.
Oh, I am sorry...Yes, that way, should be better to use images (but IMHO it's still better to use fonts :-D :-D )
