Hi,
I've got a bit of a problem with Alpha icon support. I am trying to get
alpha blending working in my application, in a toolbar and a
shortcutbar.
Initially, I was using Toolkit Pro 8.6, and had the following situation:
- alpha icons load fine under Windows XP
- alpha icons are not displayed under Windows 2000/NT, and the
application falls back to my default non-alphablended
toolbars/shortcut bar (XTPImageManager()->IsAlphaIconsSupported()
returns FALSE)
To try to make the program display correctly on 2000/NT, I upgraded to
Toolkit Pro 8.7. However, now I have the following behaviour:
- alpha icons are not displayed under Windows XP, and the
application falls back to my default non-alphablended
toolbars/shortcut bar (even though XTPImageManager()->IsAlphaIconsSupported() returns TRUE!)
- Under 2000/NT, toolbar icons fall back to their non-alphablended
defaults, and shortcutbar icons disappear entirely (just empty space!)
Clearly it's not a fault with my code only, since it happens with the
demo programs, such as ShortCutBar and GUI_WinZip. (Even the
pre-compiled demos downloaded from this site are the same, so it's not
an error in my compile environment, either.) As per the
recommendation in another post, I have tried both 16- and 24-bit
graphics, which made no difference.
So, how can I make this work? And why do the ShortCutBar and
GUI_WinZip demos I downloaded not display correctly on any of the Win2K
boxes here?
Thanks,
Dean
