python - wxpython listctrl 并修复列宽

Question

我试图在我的面板中使“表格”看起来不错。我遇到的这个问题是表格填满了面板，但一切都在左边。我想让每一列的大小相同，并跨越面板的整个宽度。我见过 ListCtrlAutoWidthMixin 但不确定如何利用它。这是我在代码中的内容：

        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，表格跨越面板，但我的所有列都向左移动。此外，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）。我已经尝试过这种方法，但似乎无法获得正确的面板尺寸。我用 GetSize() 和 GetClientSize() 得到的数字都太小了。

谢谢你的帮助！

Answer 1

我认为该GetSize()方法的问题可能是您在大小调整器的效果发生之前调用它，因此它在大小调整器调整大小以适合面板之前返回 ListCtrl 的原始大小。在代码的最后一行之后尝试此代码：

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

You should use the RowColSizer, which is quite fit for your request. Here is a small demo how to use it:

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)
