響應StaticBox？

Question

我想創建某種日誌框來流化python應用程序的控制檯輸出。

爲了在用戶界面內更好的出現，我想將TextCtrl放入StaticBox，理想情況下在用戶調整主框架時將其展開。我已經嘗試添加GridBagSizer，它允許使用AddGrowableCol(index)和AddGrowableRow(index)方法。然而讓行「可增長」有沒有影響，這是只是在一瞬間水平工作：

#!/usr/bin/python 
# -*- coding: utf-8 -*- 

import wx 

class Example(wx.Frame): 

    def __init__(self, parent, title):  
     super(Example, self).__init__(parent, title=title, 
      size=(450, 350)) 

     self.InitUI() 
     self.Centre() 
     self.Show()  

    def InitUI(self): 

     self.main_sizer = wx.GridBagSizer(5, 5) 

     # Create the grouping box and sizer for the outline 
     self.box = wx.StaticBox(self, -1, "Logging") 
     self.bsizer = wx.StaticBoxSizer(self.box, wx.VERTICAL) 

     # Create the sizer and place controls within box 
     self.gbs = wx.GridBagSizer(5,5) 

     self.log_ctrl = wx.TextCtrl(self, size=(-1, 200), style=wx.TE_MULTILINE|wx.VSCROLL) 
     self.gbs.Add(self.log_ctrl, (0,0), flag=wx.EXPAND|wx.ALL, border=10) 

     # Place the control inside group box 
     self.bsizer.Add(self.gbs, flag=wx.EXPAND) 
     self.gbs.AddGrowableCol(0) 

     # Adding to the main sizer 
     self.main_sizer.Add(self.bsizer, pos=(0, 0), span=(1, 30), flag=wx.EXPAND|wx.BOTTOM) 
     self.main_sizer.AddGrowableCol(0) 

     # Place the static group box sizer within the border frame 
     # Creating a border that the static box will sit inside 
     self.border = wx.BoxSizer() 
     self.border.Add(self.main_sizer, 1000, wx.ALL, 15) 
     self.SetSizerAndFit(self.border) 


if __name__ == '__main__': 

    app = wx.App() 
    Example(None, title="Example") 
    app.MainLoop() 

問：是否有添加wx.TextCtrl元素爲wx.StaticBox的任何巧妙的方式爲了填充主窗口垂直以及橫向什麼時候展開呢？

     self.SetSizerAndFit(self.border) 

• 首先，你忘了做AddGrowableRow，這是顯而易見的。
• 其次，self.gbs必須有比例= 1（或更多），否則它不會增長。
• 最後，您的主尺寸不會在邊框內展開。

此外，我已將self.box作爲self.log_ctrl的父級，它應該是從wx 2.9.1開始的正確方法。

在您的例子中，GridBagSizers是完全沒有必要的：

def InitUI(self): 
     # Create the grouping box and sizer for the outline 
     self.box = wx.StaticBox(self, -1, "Logging") 
     self.bsizer = wx.StaticBoxSizer(self.box, wx.VERTICAL) 

     self.log_ctrl = wx.TextCtrl(self.box, size=(-1, 200), style=wx.TE_MULTILINE|wx.VSCROLL) 
     self.bsizer.Add(self.log_ctrl, proportion=1, flag=wx.EXPAND|wx.ALL, border=10) 

     # Place the static group box sizer within the border frame 
     # Creating a border that the static box will sit inside 
     self.border = wx.BoxSizer() 
     self.border.Add(self.bsizer, proportion=1, flag=wx.ALL | wx.EXPAND, border=15) 
     self.SetSizerAndFit(self.border)
