Question

Use Matlab GUIDE to create a program with graphic user interfac(GUI). The program is designed to convert the temperature from Celsius to Fahrenheit and the opposite.

(Hint: use radio button)

Answer 1

# Hi i have solve this question using radio button if you have any query feel free to ask

# I have attach image file go through it

# Temperature Converter Program

from Tkinter import*

def submit():
entTemp = 0
entTemp = fahEntry.get()
Fahrenheit = 0
if var.get() == 1:
Fahrenheit = (int(entTemp) * 9/5) + 32
lalresult.set(Fahrenheit);

else:
fahToCel = (int(entTemp) - 32) * 5/9
lalresult.set(fahToCel);

# Program Starts from Here
root = Tk()
root.title("Temperature Converter")
mainframe = Frame(root)
mainframe.grid()
var = IntVar()
celTempVar = IntVar()
celTempVar.set(int(0))
fahTempVar = IntVar()
fahTempVar.set(int(0))
var.set(1)
lalresult = IntVar()

celLabel = Label (mainframe, text = "Enter Temperature : ", font = ("Arial", 16), fg = "black")
celLabel.grid(row = 2, column = 0, pady = 15, sticky = NW)

celLabelresultLbl = Label (mainframe, text = "Result : ", font = ("Arial",9) ,fg = "blue")
celLabelresultLbl.grid(row = 2, column = 1, pady = 50, padx = 35 , sticky = NW)

celLabel1 = Label (mainframe, text = "Result : ", font = ("Arial",9), textvariable = lalresult ,fg = "blue")
celLabel1.grid(row = 2, column = 1, pady = 50, padx = 105 , sticky = NW)

fahEntry = Entry (mainframe, width = 50, bd = 5, textvariable = fahTempVar)
fahEntry.grid(row = 2, column = 1, pady = 10, sticky = NW, padx = 30 )
radioButton = Radiobutton(root, text="Fahrenheit", variable = var , value=1 )
radioButton1 = Radiobutton(root, text="Celcius" , variable = var , value=2)
radioButton.grid(row = 1, pady = 5, sticky = NW, padx = 145 )
radioButton1.grid(row = 1, pady = 5, sticky = NW, padx = 250 )

submitButton = Button (mainframe, text = "Submit", font = ("Arial", 8, "bold"), relief = RAISED, bd=5, justify = CENTER, highlightbackground = "red", overrelief = GROOVE, activebackground = "green", activeforeground="blue", command = submit )
