Description:
 def resizeEvent(self, event):
 """Resize scene so that it fits the whole widget. Parameters event : instance of QtCore.QEvent not important Notes ----- This function overwrites Qt function, therefore the non-standard name. Argument also depends on Qt. The function is used to change the scale of view, so that the scene fits the whole scene. There are two problems that I could not fix: 1) how to give the width of the label in absolute width, 2) how to strech scene just enough that it doesn't trigger a scrollbar. However, it's pretty good as it is now. """
