OK - yes you can do that, but that class will not help you.
You can attach an image to any button - the attached fluid example file
shows how that might work.
You will need to provide two small PNG files to use for this, both 40x40
pixels, one called "up.png" and the other called "dn.png", then use
fluid to generate the C++ source files from this example.
Fluid will convert the PNG data into XPM data embedded in the source
files, and the example should then show the image in place of the
button.
For the best effect, try PNG images with a transparent background.
Hopefully that will be what you are wanting.
