在控制中心中选择通知样式nodoka或coco-->弹出通知,是否正确显示计时器。
对于

   notify2
   
   
   def mess_callback():

定义初始化(self,parent,caption,msg,timeout=none,emergency=none):

否则:紧急程度=0

caps=notify2.get_server_caps()。
mess.set_timeout(timeout)毫秒
#如果没有下面的“添加动作”选项,则不会显示超时的倒计时。


通知(无,“错误2”,“此消息将在默认值后超时”,超时=-1)
通知(无,“注意”,“重要信息”,超时=20000,紧急=1)

notify2.uninit()取消注册


gi.需要_版本(“通知”,“0.7”)。



如果紧急:通过

img='/home/rolf/myapp.png'
mess=notify.notification.new(caption,msg,img)传递图像是可选的
混乱。设置紧急(紧急)0-低,1-正常,2-关键
如果超时!=0,大写为“actions”:


消息(无,“错误2”,“此消息将在默认值后超时”,timeout=-1)
消息(无,“注意”,“重要消息”,超时=20000,紧急=1)
   
    
在标准通知中。我只能假设移动到GTK+3实际上隐藏了计时器。它在那里,但几乎看不见。

在控制中心中选择通知样式nodoka或coco-->弹出通知,会正确显示计时器。

结束更新

使用标准通知模块notify2和Notify在gi.repository你只需要添加一个动作,即使你不打算使用它。

注意:我发现似乎没有任何书面的原因。

除了在通知中添加一个关闭按钮外,它还提供一个根据提供的超时时间减少的时钟面。

对于通知2以下内容:

import notify2

class Notify():
    def mess_callback():
        pass

    def __init__(self,parent,caption,msg,timeout=None,urgency=None):
        if timeout != None: pass
        else: timeout = 0 # message should not timeout

        if urgency: pass
        else: urgency = 0

        img = '/home/rolf/MyApp.png'
        caps = notify2.get_server_caps()    
        mess = notify2.Notification(caption,msg,img) # passing an image is optional
        mess.set_timeout(timeout) #milliseconds
        mess.set_urgency(urgency) #0-Low, 1-Normal, 2-Critical
        # Without the following `add_action` option, No countdown to the time out is shown
        if timeout != 0 and 'actions' in caps:
            mess.add_action("close","Close",self.mess_callback,None) #Show the countdown to close
        mess.show()

if __name__ == "__main__":
    notify2.init("MyApp") #Register MyApp

    Notify(None,"Error","This message is not timed and has to be manually cancelled")
    Notify(None,"Error 2","This message will timeout after the default value",timeout=-1)
    Notify(None,"Information","An Unimportant message",timeout=20000,urgency=0)
    Notify(None,"Attention","An Important message",timeout=20000,urgency=1)
    Notify(None,"Emergency","A Critical message",timeout=20000,urgency=2)

    notify2.uninit() #Un-register


使用通知在Gi.存储库

import gi
gi.require_version('Notify', '0.7')
from gi.repository import Notify

class Message():
    def mess_callback():
        pass

    def __init__(self,parent,caption,msg,timeout=None,urgency=None):
        if timeout != None: pass
        else: timeout = 0 # message should not timeout

        if urgency: pass
        else: urgency = 0

        img = '/home/rolf/MyApp.png'
        caps = Notify.get_server_caps()    
        mess = Notify.Notification.new(caption, msg, img) # passing an image is optional
        mess.set_timeout(timeout) #milliseconds
        mess.set_urgency(urgency) #0-Low, 1-Normal, 2-Critical
        # Without the following `add_action` option, No countdown to the time out is shown
        if timeout != 0 and 'actions' in caps:
            mess.add_action("close","Close",self.mess_callback,None) #Show the countdown to close
        mess.show()

if __name__ == "__main__":
    Notify.init("MyApp") #Register MyApp

    Message(None,"Error","This message is not timed and has to be manually cancelled")
    Message(None,"Error 2","This message will timeout after the default value",timeout=-1)
    Message(None,"Information","An Unimportant message",timeout=20000,urgency=0)
    Message(None,"Attention","An Important message",timeout=20000,urgency=1)
    Message(None,"Emergency","A Critical message",timeout=20000,urgency=2)
