响应式StaticBox？

Question

我想创建一些日志框来流式传输python应用程序的控制台输出。

为了在UI中获得更好的外观，我想将TextCtrl扔进StaticBox，并在用户调整主框架大小时理想地展开它。我已经尝试添加GridBagSizer，允许使用AddGrowableCol(index)和AddGrowableRow(index)方法。然而，使行“可增长”没有任何效果，而目前只能水平工作：

#!/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()

问题：是否有任何聪明的方法可以将wx.TextCtrl元素添加到wx.StaticBox以便填充主窗口 vertical 扩展时为水平？

         self.SetSizerAndFit(self.border)

• 首先，你忘了做AddGrowableRow，这是显而易见的。
• 其次，self.gbs必须具有比例= 1（或更多），否则它将不会增长。
• 最后，您的主sizer不会在边框内展开。

另外，我已经将self.box作为self.log_ctrl的父级，这应该是自wx 2.9.1以来的正确方法。

在您的示例中，GridBagSizer完全没必要：

    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)
