Listctrl + images + wxpython

Salut,
   je voudrais savoir comment il est possible d'ajouter des images ou icones dans une listCtrl en wxpython. Je
sais comment mettre du texte mais par contre je ne sais pas comment inserer une image. Donc si vous avez des idées merci de m'en faire part

Re : Listctrl + images + wxpython

Pour voir ça tu peux installer les exemples de wxpython via tes dépôts :

sudo apt-get install wx2.6-examples

Et en l'occurence le code qui t'interesse :

import  wx
import  images

#----------------------------------------------------------------------

class TestVirtualList(wx.ListCtrl):
    def __init__(self, parent, log):
        wx.ListCtrl.__init__(
            self, parent, -1, 
            style=wx.LC_REPORT|wx.LC_VIRTUAL|wx.LC_HRULES|wx.LC_VRULES
            )

        self.log = log

        self.il = wx.ImageList(16, 16)
        self.idx1 = self.il.Add(images.getSmilesBitmap())
        self.SetImageList(self.il, wx.IMAGE_LIST_SMALL)


        self.InsertColumn(0, "First")
        self.InsertColumn(1, "Second")
        self.InsertColumn(2, "Third")
        self.SetColumnWidth(0, 175)
        self.SetColumnWidth(1, 175)
        self.SetColumnWidth(2, 175)

        self.SetItemCount(1000000)

        self.attr1 = wx.ListItemAttr()
        self.attr1.SetBackgroundColour("yellow")

        self.attr2 = wx.ListItemAttr()
        self.attr2.SetBackgroundColour("light blue")

        self.Bind(wx.EVT_LIST_ITEM_SELECTED, self.OnItemSelected)
        self.Bind(wx.EVT_LIST_ITEM_ACTIVATED, self.OnItemActivated)
        self.Bind(wx.EVT_LIST_ITEM_DESELECTED, self.OnItemDeselected)


    def OnItemSelected(self, event):
        self.currentItem = event.m_itemIndex
        self.log.WriteText('OnItemSelected: "%s", "%s", "%s", "%s"\n' %
                           (self.currentItem,
                            self.GetItemText(self.currentItem),
                            self.getColumnText(self.currentItem, 1),
                            self.getColumnText(self.currentItem, 2)))

    def OnItemActivated(self, event):
        self.currentItem = event.m_itemIndex
        self.log.WriteText("OnItemActivated: %s\nTopItem: %s\n" %
                           (self.GetItemText(self.currentItem), self.GetTopItem()))

    def getColumnText(self, index, col):
        item = self.GetItem(index, col)
        return item.GetText()

    def OnItemDeselected(self, evt):
        self.log.WriteText("OnItemDeselected: %s" % evt.m_itemIndex)


    #---------------------------------------------------
    # These methods are callbacks for implementing the
    # "virtualness" of the list...  Normally you would
    # determine the text, attributes and/or image based
    # on values from some external data source, but for
    # this demo we'll just calculate them
    def OnGetItemText(self, item, col):
        return "Item %d, column %d" % (item, col)

    def OnGetItemImage(self, item):
        if item % 3 == 0:
            return self.idx1
        else:
            return -1

    def OnGetItemAttr(self, item):
        if item % 3 == 1:
            return self.attr1
        elif item % 3 == 2:
            return self.attr2
        else:
            return None

    win = TestVirtualList(nb, log)
    return win

This example demonstrates the ListCtrl's Virtual List features. A Virtual list
can contain any number of cells, but data is not loaded into the control itself.
It is loaded on demand via virtual methods <code>OnGetItemText(), OnGetItemImage()</code>,
and <code>OnGetItemAttr()</code>. This greatly reduces the amount of memory required
without limiting what can be done with the list control itself.

<html>
<body>
This class encapsulates a platform-independent image. An image can be created 
from data, or using <code>wxBitmap.ConvertToImage</code>. An image can be loaded from 
a file in a variety of formats, and is extensible to new formats via image 
format handlers. Functions are available to set and get image bits, so it can 
be used for basic image manipulation.

<p>The following image handlers are available. wxBMPHandler is always installed 
by default. To use other image formats, install the appropriate handler or use
<code>wx.InitAllImageHandlers()</code>.

<p>
<table>    
<tr><td width=25%>wxBMPHandler</td>  <td>For loading and saving, always installed.</td></tr>
<tr><td>wxPNGHandler</td>  <td>For loading and saving.</td>  </tr>
<tr><td>wxJPEGHandler</td>  <td>For loading and saving.</td>  </tr>
<tr><td>wxGIFHandler</td>  <td>Only for loading, due to legal issues.</td>  </tr>
<tr><td>wxPCXHandler</td>  <td>For loading and saving.</td>  </tr>
<tr><td>wxPNMHandler</td>  <td>For loading and saving.</td>  </tr>
<tr><td>wxTIFFHandler</td>  <td>For loading and saving.</td>  </tr>
<tr><td>wxIFFHandler</td>  <td>For loading only.</td>  </tr>
<tr><td>wxXPMHandler</td>  <td>For loading and saving.</td> </tr> 
<tr><td>wxICOHandler</td>  <td>For loading and saving.</td>  </tr>
<tr><td>wxCURHandler</td>  <td>For loading and saving.</td>  </tr>
<tr><td>wxANIHandler</td>  <td>For loading only.</td> </tr>
</table>

<p>When saving in PCX format, wxPCXHandler will count the number of different 
colours in the image; if there are 256 or less colours, it will save as 8 bit, 
else it will save as 24 bit.

<p>Loading PNMs only works for ASCII or raw RGB images. When saving in PNM format, 
wxPNMHandler will always save as raw RGB.

Re : Listctrl + images + wxpython

Bon j'ai essayé de le faire marcher mais j'ai toujours un probleme. En effet, les images ne s'affichent toujours pas pourtant je fais comme c'est montré dans les exemples:

import  wx

class Configuration(wx.Frame):
	def __init__(self):
		wx.Frame.__init__(self, parent = None, id = -1, title = u"Preference",style=wx.DEFAULT_FRAME_STYLE,size=(400,400))

		bmp = wx.Image('bitmaps/image.bmp', wx.BITMAP_TYPE_BMP).ConvertToBitmap()
		gif = wx.Image('bitmaps/image.gif', wx.BITMAP_TYPE_GIF).ConvertToBitmap()
		png = wx.Image('bitmaps/image.png', wx.BITMAP_TYPE_PNG).ConvertToBitmap()
		jpg = wx.Image('bitmaps/image.jpg', wx.BITMAP_TYPE_JPEG).ConvertToBitmap()

		self.list = wx.ListCtrl(self, -1, style=wx.LC_REPORT)
		
		self.list.il = wx.ImageList(16, 16)
		self.list.idx1 = self.list.il.Add(bmp)
		self.list.idx2 = self.list.il.Add(gif)
		self.list.idx3 = self.list.il.Add(png)
		self.list.idx4 = self.list.il.Add(jpg)
		
		print self.list.SetImageList(self.list.il, wx.IMAGE_LIST_NORMAL)
		[i][b]self.list.InsertImageItem(?, ?)  // Je pense qu'il faut utiliser cette fonction[/i][/b]
		self.list.InsertColumn(0, "First")
		self.list.InsertColumn(1, "Second")
		self.list.InsertColumn(2, "Third")
		self.list.SetColumnWidth(0, 175)
		self.list.SetColumnWidth(1, 175)
		self.list.SetColumnWidth(2, 175)
		self.list.InsertStringItem(0, "ligne0 colonne0")
		self.list.SetStringItem(0, 1,"ligne0 colonne1")
		self.list.SetStringItem(0, 2,"ligne0 colonne2")
		
class Fenetre(wx.App):
	def OnInit(self):
		fen = Configuration()
		fen.Show(True)
		self.SetTopWindow(fen)
		return True

app = Fenetre()
app.MainLoop()
