Wxpython 如何从 Panel2 获取 ComboBox 的 Panel1 的值
Wxpython How to get the ComboBox's value of Panel1 from Panel2
现在我有两个Panel Panelone 和Paneltwo 并且在Frame 中使用notebook
当我点击按钮时，我想 return Panelone 的值到 PanelTwo
喜欢
class PanelTwo(wx.panel):
def __init__(self,parent):
super(PanelTwo,self).__init__(parent)
self.choice1 = wx.ComboBox(self,value=**the Panelone Value**,choices=,style=wx.CB_SORT, pos=(100, 5)) or
self.choice1.SetValue(the Panelone Value)
class Panelone(wx.panel):
def __init__(self,parent):
choicelist = ['1','2','3','5','6']
super(Panelone,self).__init__(parent)
self.choice = wx.ComboBox(self,value="1",choices=choicelist,style=wx.CB_SORT, pos=(100, 5))
self.btn = wx.Button(self, label="Summit",pos=(250, 10), size=(80, 50))
self.Bind(wx.EVT_BUTTON, self.BtnCheck, self.btn)
def BtnCheck(self,event):
**When I click the button, I want to return the value of Panelone to PanelTwo**
class Game(wx.Frame):
def __init__(self, parent, title):
super(Game, self).__init__(parent, title=title, size=(900, 700))
self.InitUI()
def InitUI(self):
nb = wx.Notebook(self)
nb.AddPage(PanelOne(nb), "PanelOne")
nb.AddPage(PanelTwo(nb), "PanelTwo")
self.Centre()
self.Show(True)
首先，如果你正在学习，我建议你使用WxGlade来构建你的图形界面。你的代码是纯粹的意大利面条，充满了语法错误:(.
对于您的示例，它非常简单，因为所有元素都属于同一个文件并且位于同一个 class.
例如：
#!/usr/bin/env python
# -*- coding: UTF-8 -*-
import wx
# THE MAIN FRAME:
class MainFrame(wx.Frame):
def __init__(self, *args, **kwds):
kwds["style"] = kwds.get("style", 0) | wx.DEFAULT_FRAME_STYLE
wx.Frame.__init__(self, *args, **kwds)
self.SetSize((734, 501))
# The main notebook:
self.main_notebook = wx.Notebook(self, wx.ID_ANY)
# Notebook's panels:
self.panel1 = wx.Panel(self.main_notebook, wx.ID_ANY)
self.panel2 = wx.Panel(self.main_notebook, wx.ID_ANY)
# Content of panel1:
self.choiceFruits = wx.Choice(self.panel1, wx.ID_ANY, choices=[])

但这并不常见。通常每个面板将在其自己的 class 内的单独文件中。在这种情况下，您必须将主框架的引用传递给每个面板，然后我们使用这个引用来访问主框架上的元素（例如，另一个面板）。
