Problems with wx.ListCtrl

Here is a snippet

    self.list_ctrl = wx.ListCtrl(self, size=(-1,100),
                     style=wx.LC_ICON|wx.LC_ALIGN_LEFT
                     )
    il = wx.ImageList(16,16,True)
    png = wx.ArtProvider.GetBitmap(wx.ART_FILE_OPEN,wx.ART_OTHER, (16,16))
    il.Add(png)
    self.list_ctrl.AssignImageList(il,wx.IMAGE_LIST_NORMAL)


    sizer = wx.BoxSizer(wx.VERTICAL)
    sizer.Add(self.list_ctrl, 0, wx.ALL|wx.EXPAND, 5)
    self.SetSizer(sizer)

    self.list_ctrl.InsertImageStringItem(0,"1",0)
    self.list_ctrl.InsertImageStringItem(1,"2",0)

My problem is that the icons appear to the top of the text which should not happen because I put wx.LC_ALIGN_LEFT in the style. I would like the icons to appear left of the text.

Another problem is that, I want one element per row. In my code it is almost like one element per column.

Can anyone help me with any of these problems? Thanks.

Looking at the wxPython demo for the ListCtrl, it looks like they use SetImageList() instead of AssignImageList(). Not sure what the difference is though. I don't see where you're inserting any text though. You'd need to use SetStringItem to put text in the other columns from what I can see.

EDIT: Code from wxPython Demo package, ListCtrl demo:

self.il = wx.ImageList(16, 16)

self.idx1 = self.il.Add(images.Smiles.GetBitmap())
self.sm_up = self.il.Add(images.SmallUpArrow.GetBitmap())
self.sm_dn = self.il.Add(images.SmallDnArrow.GetBitmap())

And then we add data / images to the widget

def PopulateList(self):
    if 0:
        # for normal, simple columns, you can add them like this:
        self.list.InsertColumn(0, "Artist")
        self.list.InsertColumn(1, "Title", wx.LIST_FORMAT_RIGHT)
        self.list.InsertColumn(2, "Genre")
    else:
        # but since we want images on the column header we have to do it the hard way:
        info = wx.ListItem()
        info.m_mask = wx.LIST_MASK_TEXT | wx.LIST_MASK_IMAGE | wx.LIST_MASK_FORMAT
        info.m_image = -1
        info.m_format = 0
        info.m_text = "Artist"
        self.list.InsertColumnInfo(0, info)

        info.m_format = wx.LIST_FORMAT_RIGHT
        info.m_text = "Title"
        self.list.InsertColumnInfo(1, info)

        info.m_format = 0
        info.m_text = "Genre"
        self.list.InsertColumnInfo(2, info)

    items = musicdata.items()
    for key, data in items:
        index = self.list.InsertImageStringItem(sys.maxint, data[0], self.idx1)
        self.list.SetStringItem(index, 1, data[1])
        self.list.SetStringItem(index, 2, data[2])
        self.list.SetItemData(index, key)
