Thanks. I am not sure about what does your “window” mean. In face, I changed the codes in the wxpython demo.

wxGTK requires that the window be created before you can
set its shape, so delay the call to SetWindowShape until
this event.

On wxMSW and wxMac the window has already been created, so go for it.

Shaped Window
Top level windows now have a SetShape method that lets you set a
non-rectangular shape for the window using a wxRegion. All pixels
outside of the region will not be drawn and the window will not be
sensitive to the mouse in those areas either.
“”"
if name == ‘main’:
import sys,os
import run
run.main([‘’, os.path.basename(sys.argv[0])] + sys.argv[1:])
And my problem is:
The shapedwindow is ok for me, but it looks a little dirty, you can see this by picture “compare.jpg”
The left picture is PS picture, and the right picture is my shapedwindow.
As you know, the picture is ok if we open it with other photogram view tools.
Best Wishes,

Hi usr root,
I think what you’re looking for is:
window.SetShape(wx.RegionFromBitmap(self.bmp))
though, I use this call on a wx.Frame in my app as opposed to a ShapedWindow, so I can’t guarantee it’ll work for you.

Hi All,
I used the shapedwindow in wxpython to show my picture, but the the picture frame appeared dirty.
Anyone can tell me what’s my problem?
The codes I changed in the shapewindow demo:
self.bmp = images.Vippi.GetBitmap()
To
self.bmp = wx.Image(opj(‘bitmaps/test/xianshi6.png’), wx.BITMAP_TYPE_PNG).ConvertToBitmap()
self.bmp.SetMask(wx.Mask(self.bmp, wx.BLACK))
The attached files are the picture files:
xianshi6.png – a boy I drawed it in photoshop, and saved as “png”
xianshi5.png – I used it to test the black background,it also has the same problem
compare.jpg – it’s the contrast picture.
what can I do to make the frame just like what I have drawn in PhotoShop?
Thanks!
