I want to set a non-rectangular shape for the window, but it always fails.
My code and picture is in accessory.
Please help~

I got the png from photoshop, the part out of the shape is transparent. If this png file doesn’t meet requirement, which kind of png files should I use and How can I get them?
Thanks~

wx.RegionFromBitmap uses the bitmap's mask to determine the shape of the region, however your image does not have a mask, it has an alpha-channel instead. There are a couple ways to get a mask for your image programatically (wx.Bitmap.SetMaskColour, wx.Image.ConvertAlphaToMask) or you can modify the source image so it has a mask (aka 1-bit alpha instead of 8-bit, every pixel either fully opaque or fully transparent) or just use an image format that doesn't support alpha.
