问题
It seems to me that the chartMouseClicked method gets called only when the user left-clicks on a chart. What's being called when the user right-clicks on a chart and the popup menu is displayed? I want to do something in the background when the user right-clicks before the popup menu is displayed. Thanks!
回答1:
ChartPanel implements MouseListener to display the context menu. To accommodate disparate platforms, it checks isPopupTrigger() in both mousePressed() and mouseReleased(). You may need to override both methods.
