wxpython listctrl and fix column widths

Question

I am trying to make a "table" look good within my panel. This issue I'm having is that the table fills up the panel but everything is to the left. I would like to have each column be the same size and span the entire width of the panel. I have seen the ListCtrlAutoWidthMixin but am not sure how I could utilize this. Here is what I have in code:

        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)

Again, the table spans the panel, but all my columns are shifted to the left. Also, I do not want to set the column size manually (unless I can grab the panel size and then divide by the number of columns I have -- since the program will be used on computers with different resolutions). I have tried this approach but cannot seem to get the correct size of the panels. The numbers I get with GetSize() and GetClientSize() are all too small.

Thanks for any help!

Answer 1

I think the trouble with the GetSize() approach might have been that you were calling it before the effects of the sizer took place, so it was returning the original size of the ListCtrl before the sizer resized it to fit the panel. Try this code after the last line of your code:

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)
