/** \brief subclass representing one symbol (e.g. \c \\alpha , \c \\cdot ...) node in the syntax tree
|
|
* \ingroup jkqtmathtext_items
|
|
*
|
|
* All supported symbols are stored in the static table symbols, which is filled by fillSymbolTable().
|
|
* The latter function is also the customization point for new symbols:
|
|
* - For each symbol, the instruction name is stored as key, e.g. for \c \\alpha the key \c "alpha" is stored.
|
|
* - for each instruction a SymbolFullProps describes the symbol and stores how to draw it.
|
|
* - Each symbol has global properties (GlobalSymbolFlags, e.g. how to treat it's with etz.) and a set of representations.
|
|
* Each representation is for one font-encoding (JKQTMathTextFontEncoding, i.e. Unicode, WinSymbol or Standard)
|
|
* - each encoding representation SymbolProps specifies a text to represent the symol in SymbolProps::symbol and
|
|
* can have additional flags, properties etc.
|
|
* .
|
|
*
|
|
* Font Lookup for symbols works as follows in JKQTMathTextSymbolNode:
|
|
* - if a character is found in the current (or to be used) font, it is taken from there (the font is specified in
|
|
* SymbolFullProps::fontType)
|
|
* - if the character is not found, it is looked for in the fallback fonts MTEFallbackGreek and MTEFallbackSymbols
|
|
* - as a last resort, some symbols can be created otherwise, so if neither of the two options above
|
|
* contain the required symbol, the symbol might be synthesized otherwise, or a rectangle with the size of "X" is drawn instead
|
|
* .
