Linking label mouse info with radio buttons & variables between classes

[ebsaith]

Normal variables are created in my_qlabel class (point1, point2, result)
If radioButton.Checked() saves it to the corresponding array in mainWindow class

That info is stored in an array(initial point, end point, result)
same for other radio button(initial point, end point, diffCalculationResult) // stored in a different arrays as the 2 arrays will be written to 2 different files

Using getters & setters to send variables(my_qlabel) to arrays(mainWindow) as suggested(thanks)

Please check my code out:
Correct me where need be(most of it)

Created getters and setters in my_qlabel class

int my_qlabel::getStartPoint()
{
    return x1;
}
 
int my_qlabel::getEndPoint()
{
    return y1;
}
 
 
int my_qlabel::getOrientation()
{
    return theta;
}

int my_qlabel::getStartPoint()
{
    return x1;
}
 
int my_qlabel::getEndPoint()
{
    return y1;
}
 
 
int my_qlabel::getOrientation()
{
    return theta;
}

2)radioButtons 1& 2 not declared -> they are!
3)error in if statement with regards to radioButton
4) cannot call member functions of my_qlabel with out object

reX[reCounter] = my_qlabel::getStartPoint();
... in if statement above
