/**
|
||
|
|
* @libdoc A formula editor library.
|
||
|
|
*
|
||
|
|
* The kformula editor library. There are three classes you might be interested in.
|
||
|
|
* First there is the @ref Document . It is, you guess it, the document.
|
||
|
|
* Next there is the @ref Container . It represents one formula. Each
|
||
|
|
* formula belongs to a document and a document might have any number of formulas.
|
||
|
|
* For this reason the formula should be considered as part of the document.
|
||
|
|
* The last class is
|
||
|
|
* @ref KFormulaWidget . This one is a widget that serves as view.
|
||
|
|
* You can create any number of views for each formula.
|
||
|
|
*
|
||
|
|
* The document contains functions like load/save and the undo stack as well as
|
||
|
|
* everything you need to edit the formula.
|
||
|
|
* The view provides the interface for cursor movement. Additional there is basic
|
||
|
|
* key handling (for keys that probably shouldn't be actions). However every function
|
||
|
|
* is a slot so you can use actions as well.
|
||
|
|
*
|
||
|
|
* That's all you need to know to use it. But anyway:
|
||
|
|
* At its heart this library contains formula elements. Each element is a child
|
||
|
|
* of @ref BasicElement . The elements are meant to be selfcontained and thus
|
||
|
|
* extendable.
|
||
|
|
* A formula consists of a tree of those elements.
|
||
|
|
*
|
||
|
|
* To be able to work on the element tree in a generic way there is a
|
||
|
|
* @ref FormulaCursor . Every edit operation goes through it. This way
|
||
|
|
* the cursor separetes the element tree from the outside world.
|
||
|
|
*
|
||
|
|
* If you want to edit the formula you ask the document (@ref Container )
|
||
|
|
* to create and execute a @ref Command . The commands use the currently
|
||
|
|
* active cursor to do their editing. Each command can be undone.
