Qt MML Widget Overview

QtMmlWidget implements the Presentation Markup subset of the MathML 2.0 specification with the following exceptions:

• the widget has no concept of the width of the document it is in. Hence specifying the width of an mtable element as a percentage of the document width has no effect;
• mtable doesn't support cells that span multiple rows or columns;
• mtable doesn't support the mlabeledtr element;
• operators ignore the displaystyle attribute;
• mpadded has no support for negative padding;
• mspace doesn't support the linebreak attribute;
• no support for the menclose element.
• no support for the mmultiscripts element.

QtMmlWidget relies on the presence of a Unicode font for rendering mathematical symbols. In particular, the font should contain characters in the ranges:

• 02100-021FF Letter-like Symbols, Number Forms, Arrows,
• 02200-022FF Mathematical Operators,
• 02900-029FF Supplemental Arrows, Miscellaneous Mathematical Symbols,
• 02A00-02AFF Supplemental Mathematical Operators.
