Question

这是我的代码的一个最小示例，它本身应该运行 -- 运行原样，一切都按我想要的方式布置，3 行节点均匀分布：

import wx

def createBoxes():
    outVSizer = wx.BoxSizer(wx.VERTICAL)
    outHSizer = wx.BoxSizer(wx.HORIZONTAL)
    outVSizer.AddStretchSpacer(1)
    outHSizer.AddStretchSpacer(1)
    sizer = wx.FlexGridSizer(rows=3, cols=3, vgap=35, hgap=20)

    box = {}
    boxSizer = {}
    text = wx.StaticText(panel, wx.ID_ANY, "This is a test")
    for i in range(6):
        box[i] = wx.StaticBox(panel, wx.ID_ANY, "testBox", size=(0,100))
        #boxSizer[i] = wx.StaticBoxSizer(box[i], wx.VERTICAL)
        #boxSizer[i].Add(text, proportion = 1, flag=wx.ALIGN_CENTER)
        sizer.Add(box[i], flag=wx.EXPAND)
    sizer.AddGrowableCol(0,1)
    sizer.AddGrowableCol(1,1)
    sizer.AddGrowableCol(2,1)

    outHSizer.Add(sizer, flag=wx.EXPAND, proportion=15)
    outHSizer.AddStretchSpacer(1)
    outVSizer.Add(outHSizer, flag=wx.EXPAND, proportion=15)
    panel.SetSizer(outVSizer)

app = wx.App()
frame = wx.Frame(None, size=(500,500))
panel = wx.Panel(frame)
createBoxes()
frame.Show()
app.MainLoop()

但是，当我取消注释这两个注释行并将其后的行更改为：

sizer.Add(boxSizer[i], flag=wx.EXPAND)

布局变得狭窄，节点垂直重叠等。我不知道我在这里做错了什么，有没有人有建议？

Answer 1

这是获得某些结果所需的最少更改：

    # text = wx.StaticText(panel, wx.ID_ANY, "This is a test")
    for i in range(6):
        box[i] = wx.StaticBox(panel, wx.ID_ANY, "testBox", size=(0,100))
        # change I
        text = wx.StaticText(panel, wx.ID_ANY, "This is a test")
        boxSizer[i] = wx.StaticBoxSizer(box[i], wx.VERTICAL)
        boxSizer[i].Add(text, proportion = 1, flag=wx.ALIGN_CENTER)
        # sizer.Add(box[i], flag=wx.EXPAND)
        # change II
        sizer.Add(boxSizer[i], flag=wx.EXPAND)

您已将 text 添加到六个不同的 sizer（这不是一个好主意）。其次，您必须将 StaticBoxSizer 和 而不是 静态框添加到父 sizer。

下一个问题是sizer设置了flag=wxEXPAND，但没有比例。因此它永远不会改变大小。

Answer 2

将文本小部件添加到 6 个不同的 sizer 从来都不是一个好主意。我建议为每个 sizer 创建一个 StaticText 的新实例。重叠的原因是你在使用StaticBoxsizers的时候需要增加你的vgap。

这是代码的更新版本：

import wx

def createBoxes():
    outVSizer = wx.BoxSizer(wx.VERTICAL)
    outHSizer = wx.BoxSizer(wx.HORIZONTAL)
    outVSizer.AddStretchSpacer(1)
    outHSizer.AddStretchSpacer(1)
    sizer = wx.FlexGridSizer(rows=3, cols=3, vgap=55, hgap=20)

    box = {}
    boxSizer = {}
    #text = wx.StaticText(panel, wx.ID_ANY, "This is a test")
    for i in range(6):
        box[i] = wx.StaticBox(panel, wx.ID_ANY, "testBox", size=(0,100))
        text = wx.StaticText(panel, wx.ID_ANY, "This is a test")
        boxSizer[i] = wx.StaticBoxSizer(box[i], wx.VERTICAL)
        boxSizer[i].Add(text, proportion = 1, flag=wx.ALIGN_CENTER)
        sizer.Add(boxSizer[i], flag=wx.EXPAND)
    sizer.AddGrowableCol(0,1)
    sizer.AddGrowableCol(1,1)
    sizer.AddGrowableCol(2,1)

    outHSizer.Add(sizer, flag=wx.EXPAND, proportion=15)
    outHSizer.AddStretchSpacer(1)
    outVSizer.Add(outHSizer, flag=wx.EXPAND, proportion=15)
    panel.SetSizer(outVSizer)

app = wx.App()
frame = wx.Frame(None, size=(500,500))
panel = wx.Panel(frame)
createBoxes()
frame.Show()
app.MainLoop()
