我可以将SVG图像用作按钮图标吗？

Question

Is this possible at all? I call Image.createSVG(...) and receive an Image object without any errors. I then call Button.setIcon() . But there's no icon on the button.

You need to check Image.isSVGSupported() which currently will always return false.

Back in the day J2ME supported SVG thru one of the JSR's. No platform since has supported SVG natively with the exception of the web so this doesn't work on any of the modern platforms and we didn't bother implementing this even for the JavaScript port.

In the future we'd like to have a more efficient/portable way of supporting SVG eg: https://github.com/codenameone/CodenameOne/issues/1890
