Explain the role of polymorphism in user interface
What will be an ideal response?
Polymorphism is the ability of objects belonging to different classes to perform the same operation differently. The behavior of an editor is decided by the context; it is the application that decides how the editor must behave based on settings, prior user selections, and user actions. In a drawing application, mouse movements would not produce the same results every time: if you have selected the circle tool, holding the left mouse button and dragging the mouse would produce a circle but if you have selected the rectangle tool, the same action would result in a rectangle.
