wxPython：wx.SpinCtrl边框管理

Question

我正在尝试在 wxPython 中创建一个基本的日期选择器/日历。到目前为止我已经成功了 将所有必要的小部件添加到我的网格中，但我正在努力获取它们 定位正确。虽然有很多事情我不完全明白， 我对 wx.SpinCtrl 小部件感到特别沮丧，它似乎是 被巨大的边界包围，尽管没有具体说明。任何人都可以 告诉我如何删除这个？我希望旋转控制只有几个像素 距框架顶部的距离与文本“二月”的像素数相同 从控件的底部。我尝试了各种方法，但似乎没有一个 有什么影响。

import wx
import calendar

MONTH_NAME_AS_KEY = {"January":1, "February":2, "March":3, "April":4, "May":5, "June":6,
                 "July":7, "August":8, "September":9, "October":10, "November":11,
                 "December":12}

def getMonthNumber(nameAsString):
    return MONTH_NAME_AS_KEY.get(nameAsString)


class Example(wx.Frame):

    def __init__(self, parent, title): 
        super(Example, self).__init__(parent, title=title,size=(300, 350))

        self.InitUI() 
        self.Centre() 
        self.Show()

    def InitUI(self):

        self.panel = wx.Panel(self)

        mainSizer = wx.BoxSizer(wx.VERTICAL)

        fgs = wx.FlexGridSizer(rows=2, cols=2)

        # fgs 1: blank space
        filler = wx.StaticText(self.panel, -1, label="")
        fgs.Add(filler)

        # fgs 2: creating containers
        vSizer = wx.BoxSizer(wx.VERTICAL)
        yearNavigationBox = wx.BoxSizer(wx.HORIZONTAL)
        monthNavigationBox = wx.BoxSizer(wx.HORIZONTAL)

        # year navigation
        sc = wx.SpinCtrl(self.panel,-1, "", size=(70,70))
        sc.SetRange(1980,2060)
        sc.SetValue(2011)

        yearNavigationBox.Add(sc, wx.ALL, wx.EXPAND|wx.TOP)

        # month navigation
        monthDown = wx.StaticText(self.panel, -1, label="<")    
        monthUp = wx.StaticText(self.panel, -1, label=">")      


        monthName = wx.StaticText(self.panel, wx.ID_ANY, label="February")  

        monthNavigationBox.Add(monthDown)
        monthNavigationBox.Add(monthName)
        monthNavigationBox.Add(monthUp)

        vSizer.Add(yearNavigationBox)
        vSizer.Add(monthNavigationBox)

        fgs.Add(vSizer)

        # fgs 3: the date of the month writ large
        date = wx.StaticText(self.panel, wx.ID_ANY, label='31', style=wx.ALIGN_CENTER)
        dateFont = wx.Font(150, wx.DEFAULT, wx.NORMAL, wx.BOLD)
        date.SetFont(dateFont)

        fgs.Add(date)


        # fgs 4: the date grid
        dateSquareSizer = wx.GridSizer(rows=6, cols=7, hgap=1, vgap=6)

        dayFont = wx.Font(10, wx.DEFAULT, wx.NORMAL, wx.BOLD)
        days = ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"]
        for item in days:
            day = wx.StaticText(self.panel, wx.ID_ANY, label=item)
            day.SetFont(dayFont)
            dateSquareSizer.Add(day)    

        y = 2012
        m = getMonthNumber(monthName.GetLabel())    

        gridData = list(calendar.Calendar().itermonthdays(y, m))
        while len(gridData)<43: gridData.append(0)

        for i in gridData:
            if i == 0: i=""
            square = wx.StaticText(self.panel, wx.ID_ANY, label=str(i))
            square.SetFont(dayFont)
            dateSquareSizer.Add(square, wx.ID_ANY)      

        fgs.Add(dateSquareSizer)

        mainSizer.Add(fgs, wx.ALL, 2)

        self.panel.SetSizer(mainSizer)
        mainSizer.Fit(self)

看起来您的 sizer 的 Add 签名不太正确。它应该是 sizer.Add(widget,ratio,flags,border)

你一直在跳过比例并且根本没有指定边框。如果您这样做：

yearNavigationBox.Add(sc, 0, wx.EXPAND|wx.TOP, 5)

它将把微调器放置在框架顶部下方 5 个像素处（或者在此之前添加的任何小部件）。您还有其他一些地方跳过比例标志并将其他随机内容放在其位置。你会想要经历并改变它。这里有一些教程：
