右键单击JFreeChart [英] Right-clicking on a JFreeChart

问题描述

在我看来，仅当用户在图表上单击鼠标左键时，才会调用chartMouseClicked方法.当用户右键单击图表并显示弹出菜单时，该怎么称呼?当用户在显示弹出菜单之前右键单击时，我想在后台执行某些操作.谢谢！

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!

推荐答案

ChartPanel 实现MouseListener以显示上下文菜单.为了适应不同的平台，它会在两者 mousePressed() 和 mouseReleased() .您可能需要覆盖这两种方法.

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.
