Question

我有一个有两页的平面笔记本。我希望在按下按钮的第2页上的文本ctrl中显示第1页上的文本Ctrl中输入的文本。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，文本在按下按钮时转移到该框。有一些小我不知道，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

致电时

self.secondTab = SecondTab(self)

您正在构建SecondTab类的另一个实例。你不想这样做，你想引用你在Frame中构建的实例。

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

当然，您需要将帧设置为全局，因此您可以对其进行修改。

对于任何有兴趣的人，我通过使用pubsub克服了这个障碍。我跟随迈克·德里斯科尔的例子来自他的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()

使用wx.flatnotebook
