Question

Trying to write string to a ListCtrl , I don’t understand the logic completely. Is this the proper way?

    self.rightPanel = wx.ListCtrl(spliter, -1, style=wx.LC_REPORT)
    self.rightPanel.InsertColumn(0, 'LineNumber')
    self.rightPanel.InsertColumn(1, 'log')
    self.rightPanel.SetColumnWidth(0, 8)
    self.rightPanel.SetColumnWidth(1, 80)

def writeConsole(self,str):
    item = wx.ListItem()
    item.SetText(str)
    item.SetTextColour(wx.RED)
    item.SetBackgroundColour(wx.BLACK)                    
    index = self.rightPanel.GetItemCount()        
    self.rightPanel.InsertItem(item)
    self.rightPanel.SetStringItem(index, 0, str(index))
    self.rightPanel.SetStringItem(index, 1, item.GetText())

1-Why text is not displayed in color ?
2-Why there are 2 different methods for display text in ListCtrl?

   ListCtrl.InsertItem()
   ListCtrl.SetStringItem()

I think InsertItem just loads the item to list.SetString but displays the item content.(Not Sure)

Answer 1

SetTextColour() and SetBackgroundColour() are methods of the entire listctrl, not of items.
For items you should use (valid only for report mode):

GetItemTextColour(idx_item)
SetItemTextColour(idx_item, col)

InsertItem(index, item) (item here is an instance of wx.ListItem) is one of the InsertItem() methods to add a new row on a ListCtrl.

SetStringItem(index, col, label, imageId=-1) (where index and col parameters are the row and column indexes for a cell) allows setting strings in any selected column. Other insert methods work only for the first column.
