This page will summarize ideas about creating MathML rendering and editing widget for KDE. There are several approaches to create such widget:
Implement MathML support for WebCore
From #webkit: "making WebKit do some minimal MathML rendering is probably a rather quick project, making a complete MathML renderer is probably not. building an editor on top of WebKit (or any other rendering engine which can display mathml) is probably not a very short project either. fixing up WebKit so that when it's in editing mode it knows how to edit mathML is also not a short project"
- All WebCore-powered browsers will benefit from this
- MathML will be naturally integrated into HTML widget
- WebCore is too heavy for some applications which just need to show a formula or to show many formulas in different widgets
- WebCore may be not suitable for applications which want to embed the formula in something else
Rendering code in KFormula does not heavily depend on KOffice libs and can be separated from it.
- Sharing code with KFormula
- Formula editor can also be taken from KFormula
- AFAIK KFormula code is not strictly MathML-specific, it just can load from/save to MathML
- KFormula has its own DOM model
Implement QT backend for GtkMathView
GtkMathView has clear backend/engine/frontend separation, backend for QT and frontend for QT DOM can be easily implemented. Dependency on GTK is optional so it won't be a problem.
- Very easy to implement
- More code sharing - more testing, more developers
- QT-style DOM for MathML can also be easily implemented
- Formula editor will be slightly harder to implement
- "Gtk" in the name, but I think we can live with it ;-)
