CS1760 ADV OBJECT ORIENTED PROGRAMMING Task To use JavaFX's event-handling capabilities to draw, delete and move multiple polygons. Method Create a Java application with 3 Buttons and a container for the drawing. The 3 Buttons are: Draw Polygon: When clicked, the program goes into Draw mode. The user clicks to add a point and double-clicks to add a point and complete the polygon. As points are added the whole of the polygon should be displayed. Delete Polygon: The user first selects a polygon from the drawing pane and then when this button is clicked the polygon is removed. Clear Polygons: When this button is clicked, all polygons are deleted. To move a polygon the user clicks inside a polygon and drags it. When a polygon is selected, drawn or moved it should be displayed red, otherwise a polygon should be black. Since polygons may intersect, make sure that the selection process allows every polygon to be selected even if one is completely inside another It is very useful to use the setDisabled method for Buttons to control when the user can do certain things. For example, if no polygon is selected, the Delete button should not be enabled. Turning in the Assignment Create files Assign4.fxml, Assign4.java, Assign4Controller.java. Upload all java and class files to CourseWeb. If you want you can zip all the files into a folder before you upload. Also turn in a folder containing printouts of all source code and a completed Assignment Information Sheet This assignment is due on Monday 26 March. Other Points Use Ex17.java to help with the structure of the assignment. 2. You may need to code events for pressing, clicking, dragging, releasing the mouse. 3. Look at the Polygon class in JavaFX for useful methods. 3. Use method getClickCount0 in class MouseEvent to distinguish between one and two clicks
