Detailed Description

subclass representing one symbol (e.g. \alpha , \cdot ...) node in the syntax tree

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 \alpha the key "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

Member Enumeration Documentation

◆ GlobalSymbolFlags

enum JKQTMathTextSymbolNode::GlobalSymbolFlags : uint64_t

Enumerator
NoGLobalSymbolFlags	indicates that no properties are activated
ExtendWidthInMathmode	this symbol has an extended width, when used within a moth-environment/in math-mode
SmallExtendWidthInMathmode	like ExtendWidthInMathmode but adds a smaller whitespace
MakeWhitespaceHalf	symbol uses whitespaces in its text (SymbolProps::symbol). These should be typeset as half-spaces
IntLikeSymbolCorrection	symbols, like `\int`,\iint,... require a correction in x-direction for subsequent sub-/superscripts ... this flag marks such symbols
SubSuperscriptBelowAboveSymbol	symbols, like `\int`,\iint,... if appearing in math-mode cause typesetting following sub-/superscripts below/above the symbol, not besides it.
SubscriptCorrection	symbols, like `\nabla`,... require a subscript correction in x-direction for subsequent subscripts ... this flag marks such symbols

DrawRightHBar	indicates whether to draw a bar on the right half of the character, above the xHeight, implements an italic-correction
FlipSymbolUpDown	indicates to flip the given symbol upside-down
FlipSymbolLeftRight	indicates to flip the given symbol left-right
RotateSymbol90	indicates to rotate the symbol 90 degree
DrawSlash	indicates to overdraw a slash (e.g. to combine 0 and / to form \varnothing )
DrawBackSlash	indicates to overdraw a backslash
DrawVertLine	indicates to overdraw a centered vertical line (slightly tilted if italic)
HeightIsAscent	if true, the height of the symbol equals the ascent of the font
