Write a binary calculator with Qt framework. Use QtHelloWorld project as your base. You should implement four operations for binary values, which are addition (+), subtraction (-), multiplication (*), division (/). The calculator should support binary values within 16 bits. You can care about only the integer part of the result, but you have to deal with both positive and negative values. Also implement the clear function in the calculator to clean the previous result. You can use http://www.calculator.net/binary-calculator.html to verify the result.

Note:

The user should also be able to do the calculation only by the keyboard (without clicking any widget in your calculator).

Must be Clear function and the GUI
