< Projects | Edu This page will summarize ideas about creating MathML rendering and editing widget for KDE. There are several approaches to create such widget: Contents 1 Implement MathML support for WebCore 1.1 Props 1.2 Cons 2 Separate KFormula code into shared library 2.1 Props 2.2 Cons 3 Implement QT backend for GtkMathView 3.1 Props 3.2 Cons 4 Other possibilities and thoughts 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" Props All WebCore-powered browsers will benefit from this MathML will be naturally integrated into HTML widget Cons 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 WebKit is not a Qt/KDE dependency yet. Separate KFormula code into shared library Rendering code in KFormula does not heavily depend on KOffice libs and can be separated from it. Props Sharing code with KFormula Formula editor can also be taken from KFormula Cons AFAIK KFormula code is not strictly MathML-specific, it just can import and export to MathML KFormula has its own DOM model We don't know how difficult can be the port from KOffice 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. Props Very easy to implement More code sharing - more testing, more developers QT-style DOM for MathML can also be easily implemented Cons Formula editor will be slightly harder to implement "Gtk" in the name, but I think we can live with it ;-) We add a dependency to KDEEdu/KDE (or wherever this code would sit) Other possibilities and thoughts Maybe we should create it for khtml first and then port it to webkit (that mostly depends on how kde is going to deal with them) Maybe we could create a library that can be used from khtml/webkit and also that we can use to create the mathml expression editor widget Retrieved from "https://techbase.kde.org/index.php?title=Projects/Edu/mathMLRender&oldid=14290" This page was last edited on 2 October 2007, at 21:59.
