wxPython — StaticBox Sizer 调整 Static Box 的大小

Question

这是我的代码应该自行运行的最小示例 - 按原样运行，一切都按照我想要的方式布置，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注释行之后的行更改为：

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

布局变得局促，节点垂直重叠等。 我不知道我在这里做错了什么，有人有建议吗？

Answer 1

将文本小部件添加到 6 个不同的大小器从来都不是一个好主意。我建议为每个大小器创建一个新的 StaticText 实例。重叠的原因是您在使用StaticBoxsizers时需要增加vgap。

下面是代码的更新版本：

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()

Answer 2

这将是

获得一些结果所需的最小更改：

    # 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添加到六个不同的大小器（这不是一个好主意）。其次，您必须将StaticBoxSizer而不是静态框添加到父大小器中。

下一个问题是，对于sizer，flag=wxEXPAND是设定的，但没有比例。因此，它永远不会改变大小。
