我一直在尝试最小化托盘上的应用程序,一旦它返回到屏幕我就遇到了问题。
只要我没有最小化,我的应用程序就会正常关闭,一旦我最小化,我的OnExit()就不会执行。
这是我的代码;
import wx
class simpleapp_wx(wx.Frame):
def __init__(self,parent,id,title):
wx.Frame.__init__(self,parent,id,title, pos = wx.DefaultPosition, size = wx.Size( -1,-1 ))
self.parent = parent
self.initialize()
def initialize(self):
Main_Frame = wx.BoxSizer( wx.VERTICAL ) # Creates the Main box Sizer Parent
self.icon = wx.Icon('MainIcon.ico', wx.BITMAP_TYPE_ICO) # This gets an Icon for the application
self.SetIcon(self.icon) # This assigns the Icon
self.Bind(wx.EVT_CLOSE, self.close_window) # This closes the window
self.tbicon = wx.TaskBarIcon() # This assigns the Icon control that will be used when minimixed to tray
self.Bind(wx.EVT_ICONIZE, self.OnIconify) # This calls the function that minimizes to tray (Iconize = Minimize)
self.tbicon.Bind(wx.EVT_TASKBAR_LEFT_DCLICK, self.OnTaskBarActivate) # This is what return the application to the screen. TaskBar Left Double Click
BottomButtons = wx.StdDialogButtonSizer()
self.BottomButtonsClose = wx.Button( self, wx.ID_CLOSE, "Close" )
BottomButtons.AddButton( self.BottomButtonsClose )
BottomButtons.Realize();
self.BottomButtonsClose.Bind(wx.EVT_BUTTON, self.close_window) # Button click event handler
Main_Frame.Add( BottomButtons, -1, wx.EXPAND, 5 )
self.SetSizerAndFit(Main_Frame) # makes the Parent window size to all the items on screen
self.Layout()
def close_window (self, event):
self.Destroy() # Destroy the box on close
print "Destroy"
def OnTaskBarActivate(self, evt): # Return from the Taskbar
if self.IsIconized():
print "Return to Front"
self.Iconize(False) # Hide the icon from the Taskbar
self.Show() # Show the Main Window
self.Raise() #Raise the Main Window to the screen
self.tbicon.RemoveIcon() # Remove the Icon from the Taskbar
def OnIconify(self, evt):
if evt.Iconized():
print "Minimize to Tray"
self.Iconize(True) # Show the Icon on the Taskbar
self.Hide() # Hide the Main Window from the screen
self.tbicon.SetIcon(self.icon) #Set the Icon on the Taskbar
''' ------------------------------------------------------------------------------------------------------------
Bottom of the Button and Control Definitions;
-------------------------------------------------------------------------------------------------------------'''
class MyApp(wx.App):
def OnInit(self):
frame = simpleapp_wx(None, -1, "Minimize to Tray") # Call/assign the Main Frame
frame.Show(True) # Show the Frame
frame.Centre() # Center it on the screen
return True
def OnExit(self):
print "OnExit Destroy0"
self.Destroy()
print "OnExit Destroy1"
return False
app = MyApp(0)
app.MainLoop()
我现在只用Python / wxPython编写了大约一个月的代码,这是我第一次尝试最小化托盘。我很高兴,直到我的申请没有正确关闭。我在使用IsIconize时看了很多不同的例子,但我没看到我做错了什么。
感谢您的光临。

您需要在销毁框架之前删除tbicon对象。我第一次使用它时花了一段时间来弄清楚这一点。将以下内容放入您的关闭处理程序中:
self.tbIcon.RemoveIcon()
self.tbIcon.Destroy()
self.Destroy()
你会注意到我删除了图标然后将其销毁。我知道当我用2.8做的时候我必须要回来,但也许2.9不再需要tbicon.Destroy()了。你必须玩它才能看到。
