Question

I’ve been creating an app using wxPython. I’d like to display some data using ListCtrl and I’d like the colums occuping maximum space. This is: the maximum size available is divided between the rows I have. I’ve tried this but it doesn’t work (this is the panel where listctrl is):

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

    width = self.GetParent().GetClientSize().width/5
    coches = vehiculos()    
    gris = wx.Color(220,220,220)

    self.lista = wx.ListCtrl(self, style=wx.LC_REPORT|wx.LC_HRULES|wx.LC_VRULES)
    self.lista.InsertColumn(0, "Matricula", width=width)
    self.lista.InsertColumn(1, "Tipo", width=width)
    self.lista.InsertColumn(2, "Matriculacion", width=width)
    self.lista.InsertColumn(3, "Ult. ITV", width=width)
    self.lista.InsertColumn(4, "Prox. ITV", width=width)

    i = 0   
    for data in coches:
        index = self.lista.InsertStringItem(i, data[0])
            self.lista.SetStringItem(index, 1, str(data[1]))
            self.lista.SetStringItem(index, 2, str(data[2]))
        self.lista.SetStringItem(index, 3, str(data[3]))
        self.lista.SetStringItem(index, 4, str(prox(data[1],data[2],data[3])))
        if((index+1) % 2 == 0):
            self.lista.SetItemBackgroundColour(index,gris)
        i += 1

    self.sizer = wx.BoxSizer(wx.HORIZONTAL)
    self.sizer.Add(self.lista, 1, wx.EXPAND|wx.ALL)
    self.SetSizer(self.sizer)

    self.Bind(wx.EVT_SIZE, self.OnResize)

def OnResize(self, event):
        width = self.GetParent().GetClientSize().width/5
    self.lista.SetColumnWidth(0, width)
    self.lista.SetColumnWidth(1, width)
    self.lista.SetColumnWidth(2, width)
    self.lista.SetColumnWidth(3, width)
    self.lista.SetColumnWidth(4, width)

Now, it doesn’t even occupy full window, it only shows a small square on top left corner. If I comment “self.Bind(wx.EVT_SIZE…” line, it shows full screen, but columns are small.

Thank you in advance!!!

What you are missing is event.Skip() call in the OnResize function. Some details about event propagation can be found here http://wiki.wxpython.org/EventPropagation. Alternatively you could use self.Layout().
