如何将pandas数据帧转换为一维数组？(How to convert a pandas dataframe into one dimensional array?)

 我认为这里发生的事情是第一次调用ShowModal()阻止应用程序级别（而不仅仅是帧级别）阻止第二个对话框完全初始化。 要解决此问题，我将调用Show()而不是ShowModal()并将wx.FRAME_FLOAT_ON_PARENT添加到对话框样式标志。 您还可以在对话框打开时对您不希望用户进行交互的程序部分调用Disable() 。 
 
 编辑：这是一个工作的例子： 
 
from threading import Thread
from time import sleep
import wx


class MainFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, title="TEST", size=(400, 400))
        self.Show()
        self.__someDialog = None
        self.__myThread = None

        self.__okButton = wx.Button(self, -1, "Press me")
        self.Bind(wx.EVT_BUTTON, self.__onOK)

        self.__myThread = Thread(target=self.__waitThenClose, name="Closer")
        self.__myThread.setDaemon(True)
        self.__myThread.start()

    def __onOK(self, evt):
        self.__someDialog = SomeDialog(self)
        self.__someDialog.ShowModal()

    def closeOpenDialogs(self, evt=None):
        lst = wx.GetTopLevelWindows()

        for i in range(len(lst) - 1, 0, -1):
            dialog = lst[i]
            if isinstance(dialog, wx.Dialog):
                print "Closing " + str(dialog)
                # dialog.Close(True)
                wx.CallAfter(dialog.Close)
                # sleep(1)
                # dialog.Destroy()

    def __waitThenClose(self):

        for x in range(0, 10):
            print "Sleeping..."
            sleep(1)

        wx.CallAfter(self.closeOpenDialogs)
        wx.CallAfter(self.Close, True)


class SomeDialog(wx.Dialog):
    def __init__(self, parent):
        wx.Dialog.__init__(self, parent, id=-1, title='Some Dialog')
        self.SetSize((300, 300))
        self.__anotherDialog = None
        self.__okButton = wx.Button(self, -1, "Press me")

        self.Bind(wx.EVT_BUTTON, self.__onOK)
        wx.EVT_CLOSE(self, self.__on_btn_cancel)

    def __onOK(self, evt):
        self.__anotherDialog = AnotherDialog(self)
        self.__anotherDialog.SetWindowStyleFlag(wx.FRAME_FLOAT_ON_PARENT|wx.DEFAULT_DIALOG_STYLE)
        self.__anotherDialog.Show()

    def __on_btn_cancel(self, event):
        event.Skip()
        self.EndModal(wx.ID_CANCEL)


class AnotherDialog(wx.Dialog):
    def __init__(self, parent):
        wx.Dialog.__init__(self, parent, id=-1, title='Another Dialog')
        self.SetSize((200, 200))
        wx.EVT_CLOSE(self, self.__on_btn_cancel)
        parent.Disable()

    def __on_btn_cancel(self, event):
        event.Skip()
        self.GetParent().Enable()
        # self.EndModal(wx.ID_CANCEL)


if __name__ == "__main__":

    app = wx.App()

    mainFrame = MainFrame()

    app.MainLoop()

I think what is happening here is that the first call to ShowModal() blocks the at the app level (not just the frame level) which is preventing the second dialog from becoming fully initialized. To work around this issue I would call Show() instead of ShowModal() and add wx.FRAME_FLOAT_ON_PARENT to the dialog style flags. You can also call Disable() on the parts of the program you don't want the user to interact with while the dialogs are open. 
 
EDIT: Here is a working example:
 
from threading import Thread
from time import sleep
import wx


class MainFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, title="TEST", size=(400, 400))
        self.Show()
        self.__someDialog = None
        self.__myThread = None

        self.__okButton = wx.Button(self, -1, "Press me")
        self.Bind(wx.EVT_BUTTON, self.__onOK)

        self.__myThread = Thread(target=self.__waitThenClose, name="Closer")
        self.__myThread.setDaemon(True)
        self.__myThread.start()

    def __onOK(self, evt):
        self.__someDialog = SomeDialog(self)
        self.__someDialog.ShowModal()

    def closeOpenDialogs(self, evt=None):
        lst = wx.GetTopLevelWindows()

        for i in range(len(lst) - 1, 0, -1):
            dialog = lst[i]
            if isinstance(dialog, wx.Dialog):
                print "Closing " + str(dialog)
                # dialog.Close(True)
                wx.CallAfter(dialog.Close)

                # dialog.Destroy()

    def __waitThenClose(self):

        for x in range(0, 10):
            print "Sleeping..."
            sleep(1)

        wx.CallAfter(self.closeOpenDialogs)
        wx.CallAfter(self.Close, True)

        self.__anotherDialog = AnotherDialog(self)
        self.__anotherDialog.SetWindowStyleFlag(wx.FRAME_FLOAT_ON_PARENT|wx.DEFAULT_DIALOG_STYLE)
        self.__anotherDialog.Show()

    def __on_btn_cancel(self, event):
        event.Skip()
        self.EndModal(wx.ID_CANCEL)


class AnotherDialog(wx.Dialog):
    def __init__(self, parent):
        wx.Dialog.__init__(self, parent, id=-1, title='Another Dialog')
        self.SetSize((200, 200))
        wx.EVT_CLOSE(self, self.__on_btn_cancel)
        parent.Disable()

    def __on_btn_cancel(self, event):
