wxpython - 一个框架，多个面板，模块化代码

Question

我正在开发一个相当大的GUI项目，因此使用wxpython来构建它。我有一个框架，多个具有自己功能的框架和一个导入gui组件以及其他外部函数的主文件。我决定保持gui / wxpython代码不同，以便更好地模块化代码。

我的主要问题是如何在单独的面板中执行这些功能，以及如何使用我的主python文件使它们工作。

以下是我的wxpython代码示例：

import wx

class MainFrame ( wx.Frame ):

    def __init__( self, parent ):
        wx.Frame.__init__ ( self, parent, id = wx.ID_ANY, title = wx.EmptyString, pos = wx.DefaultPosition, size = wx.Size( 800,600 ), style = wx.DEFAULT_FRAME_STYLE|wx.TAB_TRAVERSAL )

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

        bSizer1 = wx.BoxSizer( wx.VERTICAL )

        self.SetSizer( bSizer1 )
        self.Layout()

        self.panelOne = panel_one(self)
        self.panelTwo = panel_two(self)

        self.panelTwo.Hide()


        self.Centre( wx.BOTH )

    def __del__( self ):
        pass


class panel_one ( wx.Panel ):

    def __init__( self, parent ):
        wx.Panel.__init__ ( self, parent, id = wx.ID_ANY, pos = wx.DefaultPosition, size = wx.Size( 800,600 ), style = wx.TAB_TRAVERSAL )

        bSizer5 = wx.BoxSizer( wx.VERTICAL )

        self.m_button2 = wx.Button( self, wx.ID_ANY, u"MyButton", wx.DefaultPosition, wx.DefaultSize, 0 )
        bSizer5.Add( self.m_button2, 0, wx.ALL, 5 )

        self.SetSizer( bSizer5 )
        self.Layout()

        # Connect Events
        self.m_button2.Bind( wx.EVT_BUTTON, self.changeIntroPanel )

    def __del__( self ):
        pass


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



class panel_two ( wx.Panel ):


    def __init__( self, parent ):
        wx.Panel.__init__ ( self, parent, id = wx.ID_ANY, pos = wx.DefaultPosition, size = wx.Size( 800,600 ), style = wx.TAB_TRAVERSAL )

    ... some code in here ...

    def __del__( self ):
    pass

所以那些是我的gui组件。然后，在我的主文件中，我导入它并运行gui：

import gui

class MainApp(gui.MainFrame):
    def __init__(self, parent):
        gui.MainFrame.__init__(self, parent)

        self.panelOne = Panel1(self)
        self.panelTwo = Panel2(self)
        self.panelTwo.Hide()

class Panel1(gui.panel_one):
    def __init__(self, parent):
        gui.panel_one.__init__(self, parent)

    def changeIntroPanel( self, event ):
            if self.panelOne.IsShown():
                self.SetTitle("Panel Two Showing")
                self.PanelOne.Hide()
                self.PanelTwo.Show()
            else:
                self.SetTitle("Panel One Showing")
                self.PanelOne.Show()
                self.PanelTwo.Hide()
            self.Layout()


class Panel2(gui.panel_two):
    def __init__(self, parent):
        gui.panel_two.__init__(self, parent)

def main():
    app = wx.App()
    window = MainApp(None)
    window.Show(True)
    app.MainLoop()

if __name__ == '__main__':
    main()

正如您所知，我的想法是我想在我的主文件中执行所有实现。我将如何定义我在第一次在panel_one中定义的changeIntroPanel函数的功能？目前，我们的想法是隐藏panelOne并显示panelTwo。

之前我做过类似的事，但只有一帧。在这种情况下，它是微不足道的，因为所有函数都在MainFrame类中开始。在这种情况下，我发布的代码将完美运行。

感谢任何帮助。谢谢。

def OnInit(self, parent):用于wx.App，您需要def _ _init_ _(self, parent)。

关于__init__，请查看：Using inheritance in python
