I can't get my svg file to render it's alpha mask.

maxIcon16.svg:
Qt Code: 
  1. <svg baseProfile="tiny" viewBox="0 0 16 16" xmlns="http://www.w3.org/2000/svg">
  2. <defs>
  3. <mask id="maskedRect1">
  4. <path d="m4,2h10v10h-10z" fill="#fff"/>
  5. <path d="m5,3h8v8h-8z"/>
  6. <path d="m3,5h8v8h-8z"/>
  7. </mask>
  8. <mask id="maskedRect2">
  9. <path d="m2,4h10v10h-10z" fill="#fff"/>
  10. <path d="m3,5h8v8h-8z"/>
  11. </mask>
  12. </defs>
  13. <title>Maximized</title>
  14. <path d="m4,2h10v10h-10z" mask="url(#maskedRect1)"/>
  15. <path d="m2,4h10v10h-10z" mask="url(#maskedRect2)"/>
  16. </svg>

  13.     widget.setMinimumSize(QSize(128, 128))
  14.     widget.show()

  16.     sys.exit(app.exec_())

I went about it using QPixmap and QIcon as well but without any luck...

Here's the same svg only with size constraints and in a slightly more readable syntax:

maxIcon16_RAW.svg:

  2. <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.0//EN" "http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd">

  18. </svg>

I wrote the svg using a text editor so I can't be 100% sure it's not the svg it's self. But it's just a simple mask and it loads just fine in firefox and illustrator...
