Project Name

SFML Calculator

Project Description

Simple Calculator made from scratch from SFML.
All assets are made by me with Inkscape.

Time Spent

It's been 3 weeks since I've starting;
However, not all my time is spent on this project.
It's only for fun, even though the project idea is trivial

How to install

• Make sure you have SFML 2.6 Installed.
• At the moment, this version only works on windows. (since of the clipboard logic).

1. Run cmake .. inside ./build folder.
2. Run ninja inside the ./build folder.
3. Run ./calculator.exe make sure you are inside the build folder or the assets wont load.

Usability Controls

Keyboard Inputs:

0-9   :   (Add a digit)     
.     :   (Add a decimal point)    
+     :   (Add operation)      
-     :   (Subtract operation)
*     :   (Multiply operation)
/     :   (Divide operation)

Enter     :   (Equate expression)
=    :   (Equate expression)           
CTRL + C  :   (Resets)        

Copying to clipboard:

- Just **click on the texts** (which aren't buttons) and it will be copied onto the clipboard.

Requirements

• ✅ Numbers now use long long and double long, and now use stringstream to deal with number overflowing. (Dealing it with myself is too confusing.)
• ✅ Texts shouldn't overflow, they should have a limit.
• ✅ Notifies the user they copied something.
• ✅ Texts that can be copied glow a light purple for interactivity.
• ✅ Feature to copy either the results text, or the input text to the os clipboard, through right clicking.
• ✅ Implement key inputs for user experience. CTRL-C to clear, press numbers, periods, etc.
• ✅ Buttons darken on hover.
• ✅ UI Looks decent.. not horrible.

Changes to be made

1. (!DONE) Clean up the main function (Encapsulate It)
2. (!DONE) Changes to the notification sprite.

• the position of the notification png, should be below the operator character.
• it should be an image rather than pure text.

3. (!Scrapped, I prefer the current structure) Create a base pure base class UIEntity, since currently all entities require hovering, clicking, and updating.
