Question

我目前正在开发一个用户界面，我遇到了以下问题 - 当点击鼠标的右键时，我出现了一个上下文菜单 - 当我在Windows中运行界面时它完全正常，但是当我在Linux中运行它，我尝试单击鼠标右键 - 菜单消失得非常快，我只能在选择我需要的选项时将手指放在按钮上，然后小心地按下它，使用左侧按钮。这是我用于右键菜单的代码：

def rClicker(e):

try:

    def rClick_Select(e,apnd=0):
            e.widget.event_generate('<Control-a>')

    def rClick_Copy(e):
            e.widget.event_generate('<Control-c>')

    def rClick_Cut(e):
            e.widget.event_generate('<Control-x>')

    def rClick_Paste(e):
        e.widget.event_generate('<Control-v>')
        e.widget.focus()

    def rClick_Undo(e):
            e.widget.event_generate('<Control-z>')

    def rClick_Redo(e):
            e.widget.event_generate('<Control-y>')


    nclst=[

            (' Cut   ', lambda e=e: rClick_Cut(e)),
            (' Copy   ', lambda e=e: rClick_Copy(e)),
            (' Paste   ', lambda e=e: rClick_Paste(e)),
            (' Undo   ', lambda e=e: rClick_Undo(e)),
            (' Redo   ', lambda e=e: rClick_Redo(e)),
            (' Select All   ', lambda e=e: rClick_Select(e))
            ]

    rmenu = Menu(None, tearoff=0, takefocus=0)

    for (txt, cmd) in nclst:
        rmenu.add_command(label=txt, command=cmd)

    rmenu.tk_popup(e.x_root+40, e.y_root+10,entry="0")

except TclError:
    print ' - rClick menu, something wrong'
    pass

return "break"

def rClickbinder（r）：

try:
    for b in [ 'Text', 'Entry', 'Listbox', 'Label']: #
        r.bind_class(b, sequence='<Button-3>',
                         func=rClicker, add='')
except TclError:
    print ' - rClickbinder, something wrong'
    pass



    #bind context menu to a specific element
txt.bind('<Button-3>',rClicker, add='')
    #or bind it to any Text/Entry/Listbox/Label element
    #rClickbinder(master)

在Linux中运行GUI时，右键单击菜单消失得太快--Tkinter
