使用wx.flatnotebook从标签页转换为标签页

Question

我有一个有两页的平面笔记本。我希望在第1页上的文本Ctrl中输入的文本显示在第2页上的文本Ctrl中，并按下按钮。当我添加'self.secondTab = SecondTab（self）'时，我得到另一个文本框叠加在第1页上，并且文本在按钮按下时转移到该框。有一些我错过的小东西，请帮忙。

import wx 
import wx.lib.agw.flatnotebook as fnb 

class FirstTab(wx.Panel): 
    def __init__(self, parent): 
     wx.Panel.__init__(self, parent, -1) 

     self.secondTab = SecondTab(self) 

     sizer = wx.BoxSizer(wx.VERTICAL) 
     self.txtOne = wx.TextCtrl(self, -1, style=wx.TE_PROCESS_ENTER) 
     self.btnOne = wx.Button(self, -1, "Transfer text to Tab 2") 
     self.Bind(wx.EVT_BUTTON, self.sendText, self.btnOne) 

     sizer = wx.BoxSizer(wx.VERTICAL) 
     sizer.Add(self.txtOne, 0, wx.ALL, 5) 
     sizer.Add(self.btnOne, 0, wx.ALL, 5) 
     self.SetSizer(sizer) 

    def sendText(self, event): 
     text = self.txtOne.GetValue() 
     self.secondTab.txtTwo.WriteText(text) 

class SecondTab(wx.Panel): 
    def __init__(self, parent): 

     wx.Panel.__init__(self, parent, -1) 

     self.parent = parent 
     sizer = wx.BoxSizer(wx.VERTICAL) 
     self.txtTwo = wx.TextCtrl(self, -1, style=wx.TE_PROCESS_ENTER) 

     sizer = wx.BoxSizer(wx.VERTICAL) 
     sizer.Add(self.txtTwo, 0, wx.ALL, 5) 

     self.SetSizer(sizer) 

class Frame(wx.Frame): 
    def __init__(self): 
     wx.Frame.__init__(self, None, -1,"Notebook", size=(300,300)) 

     panel = wx.Panel(self) 
     notebook = wx.Notebook(panel) 

     page1 = FirstTab(notebook) 
     page2 = SecondTab(notebook) 

     notebook.AddPage(page1, "Tab 1") 
     notebook.AddPage(page2, "Tab 2") 

     sizer = wx.BoxSizer() 
     sizer.Add(notebook, 1, wx.ALL|wx.EXPAND, 5) 
     panel.SetSizer(sizer) 
     self.Layout() 

if __name__ == "__main__": 
    app = wx.App() 
    frame = Frame() 
    frame.Show() 
    app.MainLoop() 

Answer 1

当你调用

self.secondTab = SecondTab(self) 

你正在构建SecondTab另一个类的实例。你不想这样做，你想引用你在Frame中构造的实例。

global frame #reference frame constructed in main 
frame.page1.txtTwo.WriteText(text) 

当然，你需要使帧全局，所以你可以修改它。

对于任何有兴趣的人，我通过使用pubsub克服了这个障碍。我跟着迈克·德里斯科尔的例子，从他的blog

import wx 
from wx.lib.pubsub import pub 

class Frame(wx.Frame): 
    def __init__(self): 
     wx.Frame.__init__(self, None, -1,"Notebook", size=(300,300)) 

     panel = wx.Panel(self) 
     notebook = wx.Notebook(panel) 

     page1 = FirstTab(notebook) 
     page2 = SecondTab(notebook) 

     notebook.AddPage(page1, "Tab 1") 
     notebook.AddPage(page2, "Tab 2") 

     sizer = wx.BoxSizer() 
     sizer.Add(notebook, 1, wx.ALL|wx.EXPAND, 5) 
     panel.SetSizer(sizer) 
     self.Layout() 


class FirstTab(wx.Panel): 
    def __init__(self, parent): 
     wx.Panel.__init__(self, parent, -1) 

     sizer = wx.BoxSizer(wx.VERTICAL) 
     self.txtOne = wx.TextCtrl(self, -1, style=wx.TE_PROCESS_ENTER) 
     self.btnOne = wx.Button(self, -1, "Transfer text to Tab 2") 
     self.Bind(wx.EVT_BUTTON, self.sendText, self.btnOne) 

     sizer = wx.BoxSizer(wx.VERTICAL) 
     sizer.Add(self.txtOne, 0, wx.ALL, 5) 
     sizer.Add(self.btnOne, 0, wx.ALL, 5) 
     self.SetSizer(sizer) 

    def sendText(self, event): 
     text = self.txtOne.GetValue() 
     pub.sendMessage("panelListener", message = text) 

class SecondTab(wx.Panel): 
    def __init__(self, parent): 
     wx.Panel.__init__(self, parent, -1) 
     pub.subscribe(self.myListener, "panelListener") 

     sizer = wx.BoxSizer(wx.VERTICAL) 
     self.txtTwo = wx.TextCtrl(self, -1, style=wx.TE_PROCESS_ENTER) 

     sizer = wx.BoxSizer(wx.VERTICAL) 
     sizer.Add(self.txtTwo, 0, wx.ALL, 5) 

     self.SetSizer(sizer) 

    def myListener(self, message): 
     self.txtTwo.WriteText(message) 

if __name__ == "__main__": 
    app = wx.App() 
    frame = Frame() 
    frame.Show() 
    app.MainLoop()
