如何在wxpython / python中恢复最小化的窗口/框架

Question

I have 2 frames in a python script. Once the first one gets minimized, the second one shows. How do I get the original one to go from being minimized to restored after I close the second one.

Here is my code so far:

import wx
import wx.media
import os

class MainWindow(wx.Frame):

    def __init__(self,parent,id):
        wx.Frame.__init__(self,parent,id,'Music Player',size=(900,600), style=wx.MINIMIZE_BOX|wx.SYSTEM_MENU|wx.CAPTION|wx.CLOSE_BOX|wx.CLIP_CHILDREN)
        wx.Frame.CenterOnScreen(self)
        panel=wx.Panel(self)
        panel2=wx.Panel(panel,-1, (0,0), (160,600))
        ##wx.Frame.Maximize(self)
        panel.SetBackgroundColour('grey')
        panel2.SetBackgroundColour('black')

        ##MENU AND STATUS BAR
        status=self.CreateStatusBar()
        menubar=wx.MenuBar()
        file_menu=wx.Menu()
        help_menu=wx.Menu()

        ID_FILE_NEW = 1
        ID_FILE_LOAD = 2
        ID_FILE_EXIT = 3

        file_menu.Append(ID_FILE_NEW,"New Window","This will open a new window")
        file_menu.Append(ID_FILE_LOAD,"Load...", "This will let you choose a song to load")
        file_menu.Append(ID_FILE_EXIT,"Exit","This will exit the program")

        menubar.Append(file_menu,"File")
        self.SetMenuBar(menubar)

        self.Bind(wx.EVT_MENU, self.newWin, None, 1)
        self.Bind(wx.EVT_MENU, self.Load, None, 2)        
        self.Bind(wx.EVT_MENU, self.Close, None, 3)

##        heading = wx.StaticText(panel, -1, "Music Player",pos=(345,10))
        font1 = wx.Font(14, wx.DEFAULT, wx.NORMAL, wx.BOLD)
        font2 = wx.Font(14, wx.DEFAULT, wx.NORMAL, wx.BOLD)

Answer 1

the_app.SetTopWindow(wxFrameObject)
wxFrameObject.Maximize()

might work ... thats what we use

Answer 2

You should use myFrameObject.Raise() to make it come out of its minimized state. The wx.STAY_ON_TOP flag is for making the frame stay on top of all other frames when it's not minimized, but it won't do anything if you have minimized the frame.
