public DotController_VersionForQuestion4(javax.swing.JFrame view,
                                         PolkaDotDataModel model)
Method Detail

mouseClicked

public void mouseClicked(java.awt.event.MouseEvent e)
This method causes the data model to be changed when a mouse click event is detected. What this method should do: if the user clicks on a polka dot, and if the polka dot's position is in the top half of the canvas (as determined on the basis of the polka dot's centre point), then the polka dot should increase in size by 10%. if the polka dot's position is in the bottom half of the canvas (as determined on the basis of the polka dot's centre point), then the polka dot should decrease in size by 10%. Hint: look at the services provided by the class PolkaDot
