python - wxPython GUI BoxSizers

Question

好的，我有一个正在编码的应用程序，我正在尝试使布局更简单:

注意文本是如何左对齐的，输入框是如何对齐的，我在 wxPython 演示代码中看到了这一点，但它们都使用了 flexgrid sizer，而我试图只使用 BoxSizers(因为它们更简单并且因为我只了解一点 sizer，甚至在使用 BoxSizers 时遇到困难，在 6 个月内我会遇到更困难的时间)

我曾尝试将输入和文本放在两个垂直尺寸器中，然后将它们放在水平尺寸器中，但没有用，因为文本未与输入对齐。我也尝试过这样做，并且还让每个文本、输入配对都放在一个 sizer 中，甚至更糟。有什么建议吗？

这是一个仅使用 BoxSizers 的简单示例:

import wx

class MyForm(wx.Frame):

    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, "Tutorial")

        # Add a panel so it looks the correct on all platforms
        panel = wx.Panel(self, wx.ID_ANY)

        # create the labels
        lblOne = wx.StaticText(panel, label="labelOne", size=(60,-1))
        lblTwo = wx.StaticText(panel, label="lblTwo", size=(60,-1))
        lblThree = wx.StaticText(panel, label="lblThree", size=(60,-1))

        # create the text controls
        txtOne = wx.TextCtrl(panel)
        txtTwo = wx.TextCtrl(panel)
        txtThree = wx.TextCtrl(panel)

        # create some sizers
        mainSizer = wx.BoxSizer(wx.VERTICAL)
        lineOneSizer = wx.BoxSizer(wx.HORIZONTAL)
        lineTwoSizer = wx.BoxSizer(wx.HORIZONTAL)
        lineThreeSizer = wx.BoxSizer(wx.HORIZONTAL)

        # add widgets to sizers
        lineOneSizer.Add(lblOne, 0, wx.ALL|wx.ALIGN_LEFT, 5)
        lineOneSizer.Add(txtOne, 0, wx.ALL, 5)
        lineTwoSizer.Add(lblTwo, 0, wx.ALL|wx.ALIGN_LEFT, 5)
        lineTwoSizer.Add(txtTwo, 0, wx.ALL, 5)
        lineThreeSizer.Add(lblThree, 0, wx.ALL|wx.ALIGN_LEFT, 5)
        lineThreeSizer.Add(txtThree, 0, wx.ALL, 5)

        mainSizer.Add(lineOneSizer)
        mainSizer.Add(lineTwoSizer)
        mainSizer.Add(lineThreeSizer)

        panel.SetSizer(mainSizer)

# Run the program
if __name__ == "__main__":
    app = wx.App(False)
    frame = MyForm()
    frame.Show()
    app.MainLoop()

但这有点乱，所以这里有一个重构版本:

import wx

class MyForm(wx.Frame):

    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, "Tutorial")

        # create the main sizer
        self.mainSizer = wx.BoxSizer(wx.VERTICAL)

        # Add a panel so it looks the correct on all platforms
        self.panel = wx.Panel(self, wx.ID_ANY)

        lbls = ["labelOne", "lblTwo", "lblThree"]
        for lbl in lbls:
            self.buildLayout(lbl)
        self.panel.SetSizer(self.mainSizer)

    #----------------------------------------------------------------------
    def buildLayout(self, text):
        """"""
        lblSize = (60,-1)
        lbl = wx.StaticText(self.panel, label=text, size=lblSize)
        txt = wx.TextCtrl(self.panel)

        sizer = wx.BoxSizer(wx.HORIZONTAL)
        sizer.Add(lbl, 0, wx.ALL|wx.ALIGN_LEFT, 5)
        sizer.Add(txt, 0, wx.ALL, 5)
        self.mainSizer.Add(sizer)

# Run the program
if __name__ == "__main__":
    app = wx.App(False)
    frame = MyForm()
    frame.Show()
    app.MainLoop()
