Button glyphs are painted incorrectly

created 18 years ago

After upgrade to version 28 the TcxButton does not paint the glyph correctly when the glyph is loaded at run-time.
The following worked correctly before version 28:
ImageList.GetBitmap(IMAGE_MODEL_RUN, btnRun.Glyph);
If the glyph is pre-loaded at design-time it works fine.
Steps to Reproduce:
Add TcxButton to form. Do NOT assign glyph at design-time. Add code to load glyph in form's FormCreate event.

    Dear Scot,
    We are a bit overloaded with support queries after releasing the new build 28. Thus, there may be some delays in answering your requests. We do our best to process them in a timely manner. Please bear with us.
    Thanks,

      Hi Scot,
      After implementing Suggestion ID: CS18368, TcxButton - Add support for 32-bit bitmaps with alpha channel, button glyphs loaded from an image list should contain correct alpha channel information. To get proper images from image lists, call the TcxImageList.GetImage method instead of the ImageList.GetBitmap method. Said differently, please modify the code as follows:

      Delphi
      ImageList.GetImage(IMAGE_MODEL_RUN, btnRun.Glyph);

      Please try this solution and let us know your results.
      Thanks,
      Alex

        Alternatively, you can call the TcxImageList.GetImageInfo class function (in case ImageList is not a TcxImageList descendant) as shown in the following code snippet:

        Delphi
        TcxImageList.GetImageInfo(ImageList.Handle, IMAGE_MODEL_RUN, btnRun.Glyph, nil);

        Thanks,
        Alex
