我想创建某种日志来流式处理python应用程序的控制台输出。

为了使UI中的外观更好,我想将TextCtrl放入StaticBox中,并在用户调整主框架大小时理想地将其展开。我已经尝试添加允许使用GridBagSizerAddGrowableCol(index)方法的AddGrowableRow(index)。但是,使该行“可增长”没有任何效果,并且目前只能水平运行:

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:是否有任何巧妙的方法将wx.TextCtrl元素添加到wx.StaticBox,以便在扩展主窗口时既可以垂直又可以水平填充?

最佳答案

首先,您忘了执行AddGrowableRow,这很明显。
其次,self.gbs必须具有比例= 1(或更大),否则它将不会增长。
最后,您的主尺寸调整器不会在边界内扩展。


另外,我将self.box设置为self.log_ctrl的父级,这应该是自wx 2.9.1起正确的方法。

在您的示例中,GridBagSizers是完全不必要的:

    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)
