I´m making a GUI with an analysis page, where you can drag lines on different plots and get the differences in x position of the lines. I want to somehow display the difference on "PageOne" in a textbox or something similar. In the code below I´ve created global text widgets(at the very end of the code). The problem is that the text widget are also visible on the "StartPage". If I make the text widgets local variables to the PageOne Class I´m no longer able to insert data from the "DraggableLines" classes. So I´m a bit stuck at the moment. Can someone explain a good solution?
