Python 如何在带有子对话框的框架上应用MakeModel（）方法

我在Python27上使用WxPythonClassic。我的文件结构如下（见下面的代码片段）：-

frame.py=此文件包含frame和dialog的两个类（分别为MyFrame1和MyDialog1）

main.py=此文件导入上述类，并包含基于上述类的两个子类（分别为MyFrame2和MyDialog2）

现在保持文件结构如上所述，如何在对话框窗口打开时使框架窗口处于非活动状态

如何在上面的文件排列/结构上正确应用MakeModal（）方法？到目前为止，我发现的所有示例都使用了两个框架，而不是一个框架和一个对话框

frame.py

import wx

# ************ FRAME 1 ************ #
# ************ FRAME 1 ************ #
class MyFrame1 ( wx.Frame ):

    def __init__( self, parent ):
        wx.Frame.__init__ ( self, parent, id = wx.ID_ANY, title = wx.EmptyString, pos = wx.DefaultPosition, size = wx.Size( 500,300 ), style = wx.DEFAULT_FRAME_STYLE|wx.TAB_TRAVERSAL )

        self.SetSizeHintsSz( wx.DefaultSize, wx.DefaultSize )

        bSizer = wx.BoxSizer( wx.VERTICAL )

        self.child_button = wx.Button( self, wx.ID_ANY, u"Child Frame", wx.DefaultPosition, wx.DefaultSize, 0 )
        bSizer.Add( self.child_button, 0, wx.ALL|wx.ALIGN_CENTER_HORIZONTAL, 5 )


        self.SetSizer( bSizer )
        self.Layout()

        self.Centre( wx.BOTH )

        # Connect Events
        self.child_button.Bind( wx.EVT_BUTTON, self.On_child_button )

    def __del__( self ):
        pass


    # Virtual event handlers, overide them in your derived class
    def On_child_button( self, event ):
        event.Skip()



# ************ DIALOG 1 ************ #
# ************ DIALOG 1 ************ #
class MyDialog1 ( wx.Dialog ):

    def __init__( self, parent ):
        wx.Dialog.__init__ ( self, parent, id = wx.ID_ANY, title = wx.EmptyString, pos = wx.DefaultPosition, size = wx.Size( 300,200 ), style = wx.DEFAULT_DIALOG_STYLE )

        self.SetSizeHintsSz( wx.DefaultSize, wx.DefaultSize )


        self.Centre( wx.BOTH )

        # Connect Events
        self.Bind( wx.EVT_CLOSE, self.onClose )

    def __del__( self ):
        pass


    # Virtual event handlers, overide them in your derived class
    def onClose( self, event ):
        event.Skip()

import wx
from frame import MyFrame1, MyDialog1


class MyFrame2(MyFrame1):
    def __init__(self, parent):
        MyFrame1.__init__ (self, parent)

    def On_child_button( self, event ):
        MyDialog2(None).Show()


class MyDialog2(MyDialog1):
    def __init__(self, parent):
        MyDialog1.__init__ (self, parent)

    def onClose(self, event):
        self.Destroy()


app = wx.App(0)
MyFrame2(None).Show()
app.MainLoop()

main.py

import wx

        self.SetSizeHintsSz( wx.DefaultSize, wx.DefaultSize )

        bSizer = wx.BoxSizer( wx.VERTICAL )

        self.child_button = wx.Button( self, wx.ID_ANY, u"Child Frame", wx.DefaultPosition, wx.DefaultSize, 0 )

您不需要在框架上使用

MakeModal

，因为对话框已经内置了模态功能。只需调用对话框的

showmodel

方法，而不是

Show

方法

ShowModal

将创建一个嵌套的事件循环，因此在对话框完成之前，

ShowModal

不会返回，并且应用程序中其他窗口的输入将被阻止。典型的使用模式如下所示：

with MyDialog(self, foo, bar) as dlg:
    if dlg.ShowModal() == wx.ID_OK:
        # do something with dlg values

改为尝试ShowModal（）。
