Onward to the next type of problem!

Onward to the next type of problem!

The next step in the calculator is creating an option so that the user can switch between which type of calculation he/she wishes to solve. As I've mentioned before, stoichiometry contains a wide range of very diverse problems that change depending on the situation of the problem, which poses difficulty when trying to create a stable calculator. I've decided to only create two options for problems as far as this year is concerned:  two-reaction one-product (which has already been completed), and two-reaction two-product (which still needs to be created), as well as a button to be able to switch easily between the two types of problems. The button works similar to when you choose your gender when you create a new email. As one circle is selected, the other circle becomes unselected. Each circle will be labeled corresponding to the type of problem it represents. As you click on, and choose which problem you have, the GUI of the calculator changes so that you can solve that type of problem. If you were, let's say, to switch from the two-reaction one-product problem type to the two-reaction two-product problem type, the only thing the user would see visually would be added input boxes for another compound on the right side of the equation (another product). 

Currently, I am finishing up the button's code within the program, and will soon proceed to write the entire arithmetic for the two-product calculations. Again, if you have any questions over anything I'm doing, may it be general or meticulously specific, please don't hesitate to ask; I will try to post the video of the calculator in action by the end of the week.
