variables and formulas

hi,
how do you use variable and formulas in qt.

any help would appreciated.

Hi, could you elaborate?

I have been working with vb.net and have written several calculators for my use, such as celcius to farhrenheit converter and when you double click the control button on the designer form a second one pops up to write the code to do the conversion, how to do this is not apparent to me in QT, also how do you assign variables in QT(example: let a=5).

thank you for your response and taking time to answer my question:)

If you really don't know how to assign a value to a variable, you should learn C and C++ with a good book and don't try to start with Qt! :crying:
