响应式静态框？

Question

我想创建某种日志框来流式传输 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 放入 StaticBox 中，并理想地在用户调整主框架大小时扩展它。我已经尝试添加一个 GridBagSizer 允许使用 AddGrowableCol(index) 和 AddGrowableRow(index) 方法。然而，使行 'growable' 没有效果，它 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： 有什么巧妙的方法可以将 wx.TextCtrl 元素添加到 wx.StaticBox 以填充主 window 垂直和水平展开时一样吗?

         self.SetSizerAndFit(self.border)

首先，您显然忘记了执行 AddGrowableRow。
其次，self.gbs必须有比例=1（或更多），否则它不会增长。
最后，您的主 sizer 不会在边界内展开。

此外，我已经将 self.box 设置为 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，GridBagSizers 完全没有必要：

    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)
