Good day,
Created class my_label(that creates points from user clicks and draws lines on label) with Help from #Santosh Reddy.

My New Problem:
Created 2 radio buttons on main window that will do different calculations on Qpoints depending of which radio button is checked
1)However those Qpoints are STORED in my_label class, I cant access those QPoints from mainWindow class.

2)Also I Cant test if(radioButton.isChecked()) in the .cpp my_label class since its in mainWindow class.

How do I go about doing this?
(do I use signals and slots -> if so how)

Kind Regards
