wxpython listctrl和fix列宽

Question

我正在试着在我的面板中使“桌子”看起来很好。我遇到的问题是，表填充了面板，但所有内容都在左边。我希望每列都是相同的大小和跨度的整个面板。我已经看到了列表ctrlautowidthmixin，但不确定如何利用它。下面是我的代码：

        self.Analysis = scrolled.ScrolledPanel(self.Notebook3, -1)

        # Set Up Analysis Page (Page has four panels -- I care about Top left one)
        self.AnalysisUL = wx.Panel(self.Analysis,-1, style=wx.BORDER_NONE)
        self.AnalysisUR = wx.Panel(self.Analysis,-1, style=wx.BORDER_NONE)
        self.AnalysisLL = wx.Panel(self.Analysis,-1, style=wx.BORDER_NONE)
        self.AnalysisLR = wx.Panel(self.Analysis,-1, style=wx.BORDER_NONE)

        # Top Left Box (Analyze Button and Projected Points Total)
        self.Picks_Left = wx.ListCtrl(self.AnalysisUL,-1,style=wx.LC_REPORT | wx.BORDER_NONE)
        self.Picks_Left.InsertColumn(1,'col1')
        self.Picks_Left.InsertColumn(2,'col2',format=wx.LIST_FORMAT_CENTRE)
        self.Picks_Left.InsertColumn(3,'col3',format=wx.LIST_FORMAT_CENTRE)
        self.Picks_Left.InsertColumn(4,'col4',format=wx.LIST_FORMAT_CENTRE)

        self.Picks_Left.SetColumnWidth(0,-2)
        self.Picks_Left.SetColumnWidth(1,-2)
        self.Picks_Left.SetColumnWidth(2,-2)
        self.Picks_Left.SetColumnWidth(3,-2)

        # Sizer
        vbox_UL = wx.BoxSizer(wx.VERTICAL)

        #Title for Table
        fontUL = wx.Font(14, wx.DEFAULT, wx.NORMAL, wx.BOLD)
        self.UL_text = wx.StaticText(self.AnalysisUL, -1, 'Title')
        self.UL_text.SetFont(fontUL)

        vbox_UL.Add(self.UL_text, 0, wx.CENTER|wx.ALL,20)
        vbox_UL.Add(self.Picks_Left,1,wx.EXPAND|wx.ALL,3)
        self.AnalysisUL.SetSizer(vbox_UL)

同样，表跨越面板，但我的所有列都向左移动。另外，我不想手动设置列大小（除非我可以获取面板大小，然后除以我拥有的列数——因为该程序将在具有不同分辨率的计算机上使用）。我尝试过这种方法，但似乎无法得到正确的面板尺寸。我用GetSize（）和GetClientSize（）得到的数字都太小了。在

Answer 1

我认为GetSize()方法的问题可能是在sizer的效果发生之前调用它，所以在sizer调整其大小以适应面板之前，它返回了ListCtrl的原始大小。在代码的最后一行之后尝试以下代码：

table_width = self.Picks_Left.GetSize()[0] #GetSize returns (width, height) tuple
num_col = self.Picks_Left.GetColumnCount()
col_width = table_width/num_col
for i in range(0, num_col):
    self.Picks_Left.SetColumnWidth(i, col_width)

Answer 2

您应该使用RowColSizer，这非常适合您的请求。下面是一个小演示如何使用它：

import  wx  
import  wx.lib.rcsizer  as rcs

class TestPanel(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent, -1)

        sizer = rcs.RowColSizer()

        text = "This sizer lays out it's items by row and column "\
               "that are specified explicitly when the item is \n"\
               "added to the sizer.  Grid cells with nothing in "\
               "them are supported and column- or row-spanning is \n"\
               "handled as well.  Growable rows and columns are "\
               "specified just like the wxFlexGridSizer."

        sizer.Add(wx.StaticText(self, -1, text), row=1, col=1, colspan=5)

        sizer.Add(wx.TextCtrl(self, -1, "(3,1)"), flag=wx.EXPAND, row=3, col=1)
        sizer.Add(wx.TextCtrl(self, -1, "(3,2)"), row=3, col=2)
        sizer.Add(wx.TextCtrl(self, -1, "(3,3)"), row=3, col=3)
        sizer.Add(wx.TextCtrl(self, -1, "(3,4)"), row=3, col=4)
        sizer.Add(
            wx.TextCtrl(self, -1, "(4,2) span:(2,2)"), 
            flag=wx.EXPAND, row=4, col=2, rowspan=2, colspan=2
            )

        sizer.Add(wx.TextCtrl(self, -1, "(6,4)"), row=6, col=4)
        sizer.Add(wx.TextCtrl(self, -1, "(7,2)"), row=7, col=2)
        sizer.Add(wx.TextCtrl(self, -1, "(8,3)"), row=8, col=3)
        sizer.Add(
            wx.TextCtrl(self, -1, "(10,1) colspan: 4"), 
            flag=wx.EXPAND, pos=(10,1), colspan=4
            )

        sizer.Add(
            wx.TextCtrl(self, -1, "(3,5) rowspan: 8, growable col", style=wx.TE_MULTILINE),
            flag=wx.EXPAND, pos=(3,5), size=(8,1)
            )

        box = wx.BoxSizer(wx.VERTICAL)
        box.Add(wx.Button(self, -1, "A vertical box"), flag=wx.EXPAND)
        box.Add(wx.Button(self, -1, "sizer put in the"), flag=wx.EXPAND)
        box.Add(wx.Button(self, -1, "RowColSizer at (12,1)"), flag=wx.EXPAND)
        sizer.Add(box, pos=(12,1))

        sizer.Add(
            wx.TextCtrl(self, -1, "(12,2) align bottom"), 
            flag=wx.ALIGN_BOTTOM, pos=(12,2)
            )

        sizer.Add(
            wx.TextCtrl(self, -1, "(12,3) align center"), 
            flag=wx.ALIGN_CENTER_VERTICAL, pos=(12,3)
            )

        sizer.Add(wx.TextCtrl(self, -1, "(12,4)"),pos=(12,4))
        sizer.Add(
            wx.TextCtrl(self, -1, "(12,5) full border"), 
            flag=wx.EXPAND|wx.ALL, border=15, pos=(12,5)
            )

        sizer.AddGrowableCol(5)
        sizer.AddGrowableRow(9)

        sizer.AddSpacer(10,10, pos=(1,6))
        sizer.AddSpacer(10,10, pos=(13,1))

        self.SetSizer(sizer)
        self.SetAutoLayout(True)


app = wx.App()
frame = wx.Frame(None, -1)
pn = TestPanel(frame)
frame.Show()
frame.Maximize()
app.MainLoop()

同样的请求也可以通过使用aui的更奇特的方式来实现

希望它能帮到你。在
