使用Python 3.2和tkinter.如何使Button-3(右键单击)选择鼠标光标悬停在Treeview小部件中的项目？我基本上希望Button-3事件以与当前单击左键相同的方式选择项目.

你们一半回答了自己的问题.刚刚对我的代码进行了编码和测试,因此在此处发布我的解决方案代码段并没有什么坏处.

def init(self):
    """initialise dialog"""
    # Button-3 is right click on windows
    self.tree.bind("<Button-3>", self.popup)

def popup(self, event):
    """action in event of button 3 on tree view"""
    # select row under mouse
    iid = self.tree.identify_row(event.y)
    if iid:
        # mouse pointer over item
        self.tree.selection_set(iid)
        self.contextMenu.post(event.x_root, event.y_root)            
    else:
        # mouse pointer not over item
        # occurs when items do not fill frame
        # no action required
        pass
