hi. i've just been messing around with a few simple programs today to refresh my memory on C++. I decided to write a simple one and try to use a GUI development program to see if i can make a gui for it. now when you use the GUI developer to attach code to the widgets can you only attach a function for it to execute? Here is the simple program i was tryiing to make a GUI for.

(Toggle Plain Text)

#include <iostream>

using namespace std;

 int main()
{
	int NUM;
	
	cout << "Input a number: ";
	cin >> NUM;
	cout << "You entered " << NUM << "\n";
}

now because i know the input a number would be a input box would i have the first cout and cin in a function say input() and then have the widget use that function for the input box? Or is that an unecessary step? Thanks for any replies in advance.

I don't think I could help you, but it would probably help other potential helpers if you specified which GUI toolkit you were trying to use.

Windows Forms? Qt? Gtkmm?

Win API?

Look at the problem on at hand.

Your not going to be using cout and cin. So you need another way to input and output the data.

How about a label saying "Input your number: " and then a lineEdit and a pushbutton, and when it is pushed it pops up a message box saying "You enter <contents of lineEdit>".
