Problema con combobox

[razpeitia]

Tienes que usar un StaticBitmap en vez de un BitmapButton

Aqui hay un ejemplo no me funciono a mi pero con unos cuantos cambios lo hice jalar.

Código Python:

import wx, os
 
class TestFrame(wx.Frame):
    def __init__(self, *args, **kwargs):
 
        wx.Frame.__init__(self, *args, **kwargs)
        # there needs to be an "Images" directory with one or more jpegs in it in the
        # current working directory for this to work
        self.jpgs = GetJpgList("image") # get all the jpegs in the Images directory
        self.CurrentJpg = 0
 
        self.MaxSize = (200, 400)
 
        b = wx.Button(self, label= "Display next")
        self.Bind(wx.EVT_BUTTON, self.DisplayNext)
        # starting with an EmptyBitmap, the real one will get put there
        # by the call to .DisplayNext()
        self.Image = wx.StaticBitmap(self, bitmap=wx.EmptyBitmap(*self.MaxSize))
        self.DisplayNext()
 
        # Using a Sizer to handle the layout: I never like to use absolute postioning
        box = wx.BoxSizer(wx.VERTICAL)
        box.Add(b, 0, wx.CENTER|wx.ALL, 10)
 
        # adding stretchable space before and after centers the image.
        box.Add((1,1),1)
        box.Add(self.Image, 0, wx.ALIGN_CENTER_HORIZONTAL|wx.ALL|wx.ADJUST_MINSIZE, 10)
        box.Add((1,1),1)
 
        #self.SetSizerAndFit(box)
 
        wx.EVT_CLOSE(self, self.OnCloseWindow)
 
    def DisplayNext(self, event=None):
        # load the image
        Img = wx.Image(self.jpgs[self.CurrentJpg], wx.BITMAP_TYPE_JPEG)
 
        # scale the image, preserving the aspect ratio
        W = Img.GetWidth()
        H = Img.GetHeight()
        if W > H:
            NewW = self.MaxSize[0]
            NewH = self.MaxSize[0] * H / W
        else:
            NewH = self.MaxSize[0]
            NewW = self.MaxSize[0] * W / H
        Img = Img.Scale(NewW,NewH)
 
        # convert it to a wx.Bitmap, and put it on the wx.StaticBitmap
        self.Image.SetBitmap(wx.BitmapFromImage(Img))
 
        # You can fit the frame to the image, if you want.
        self.Fit()
 
        self.CurrentJpg += 1
        if self.CurrentJpg > len(self.jpgs) -1:
            self.CurrentJpg = 0
 
    def OnCloseWindow(self, event):
        self.Destroy()
 
 
def GetJpgList(dir):
    jpgs = [f for f in os.listdir(dir) if f[-4:] == ".jpg"]
    print "JPGS are:", jpgs
 
    return [os.path.join(dir, f) for f in jpgs]
 
class App(wx.App):
    def OnInit(self):
        frame = TestFrame(None, title="wxBitmap Test")
        frame.Show(True)
        return True
 
if __name__ == "__main__":
    app = App(redirect=False)
    app.MainLoop()
