\subsection page_whatsnew_TRUNK_OVERVIEW trunk: Overview
Changes, compared to \ref page_whatsnew_V4_0_0 "v4.0.0" include:
- General:
- CLEANUP (BREAKING) of library structure
- NEW: Using precompiled headers in CMake-build to speed up build times
- NEW/BREAKING: split jkqtcommon into basic tools and jkqtcommon_statistics_and_math for advanced math tools not used by all libs
- JKQTPlotter:
- FIXED issue described in #62: Fix custom labels draw, because giving exactly two label-strings did not display all of them, thanks to user:FalsinSoft
- FIXED issue #70: Typo in jkqtplotter/CMakeLists.txt, thanks to user:tedlinlab
- FIXED issue #80: Bug with multiple inheritance with Q_GDAGET with CLANG, thanks to user:igormironchik, caused by QTBUG-104874
- FIXED: styling was not properly applied to coordinate axes of colorbars outside the plot
- IMPROVED: QT6-compatibility by removing deprecated warnings
- NEW: JKQTPFilledCurveXGraph and JKQTPFilledCurveYGraph can now plot wiggle plots with different fill styles above and below the baseline (feature request #68 Wiggle Plots from user:xichaoqiang
- NEW/BREAKING CHANGE: data tooltip can now also be shown when "just" moving the mouse (so far this was only possible when dragging the mouse with a button pressed). This also removes JKQtPlotter::getActMouseLeftAsToolTip() and adds JKQtPlotter::getActMouseMoveToolTip() instead! Also the default toolbars and context menus changed!
- NEW: new "seaborn" style for plots
- NEW/BREAKING CHANGE: changed JKQTPColorDerivationMode into a struct, which extends its capabilities above the previously available few enum-items
- NEW: added debug-feature to show boxes around text in the plot
- BREAKING: Print-Support can now be switched off with a CMAKE-option JKQtPlotter_BUILD_FORCE_NO_PRINTER_SUPPORT=ON. This also switches off PDF and SVG export, partly solves issue #81, many thanks to user:sufuk for contributing part of the code and supplying the idea!
- JKQTMathText:
- FIXED: JKQTMathText added a little whitespace before and after the LaTeX-string. This was removed as it disturbed the layout of text in plots
- FIXED: height-calculation of frac-like instructions: before the ascent and descent were equal, even if the numerator and denominator have different heights
- FIXED: strikeoutPos was not correctly calculated in sub-/superscript node
- FIXED: symbol spacing in math mode (and text mode)
- FIXED/IMPROVED: JKQTMathText renders several LaTeX strings better (simple braces in math mode, \c +-*... as symbols with proper sizes in math mode, added some missing instruction aliases, improved size of \\vec and \\hat, corrrected fonts usage for \\mathrm
- FIXED: \c \\sum and \c \\prod used the wrong symbol in XITS-mode
- IMPROVED: high-dpr-support in JKQTMathText
- IMPROVED: typesetting of sub-/supercripts, especially for large math operators and braces
- MODIFIED: brace node now calculates the extension of the child height above or below the strikeoutPos, in order to center braces around the strikeoutPos
- IMPROVED: improved drawing of parantheses, square brackets ... , underbrace/overbrace
- IMPROVED: added x-correction for sub/superscript above/below/besides integrals
- IMPROVED: rendering of sqrt
- IMPROVED: rendering and size calculation of decorations
- IMPROVED: tokenizing and parsing of text in text-mode: now a lot of accents with commands like \c \\\"a, \c \\'e and variants (e.g. \c {\\\"a}, \c \\\"{a}, ...) are supported now
- IMPROVED/BREAKING: refactored symbol node JKQTMathTextSymbolNode and changed font-lookup!
- IMPROVED/NEW/BREAKING: refactored whitespace-processing node JKQTMathTextWhitespaceNode, now all major LaTeX whitespace commands are supported properly
- IMPROVED/NEW/BREAKING: refactored LaTeX parser in JKQTMathText
- REMOVED/BREAKING: \c \\v[a-zA-Z] and shorthand for \c \\vec{a-zA-Z} was removed, implementation of \c \\bbR,\c \\bbC,... changed
- MODIFIED/BREAKING: new options interface for JKQTMathText::parse()
- EMOVED/BREAKING: removed JKQTMathtext::unparsedNode
- IMPROVED/REWORKED rendering of text in text- and math-mode. Now it is more consistent with the output of LaTeX itself
- IMPROVED/REWORKED rendering of blackboard font: now several different rendering modes can be selected using JKQTMathText::setFontBlackboradMode()
- BREAKING/REWORKED: The \\verb!...!-command now works the same as in LaTeX
- BREAKING/CLEANUP: cleanup: Removed Parameter prevNodeSize from JKQTMathTextNode::draw() and JKQTMathTextNode::getSize()/JKQTMathTextNode::getSizeInternal(), since it is only really necessary for JKQTMathTextSubscriptNode and JKQTMathTextSuperscriptNode
- BREAKING/CLEANUP: using JKQTMathTextNodeSize for all size-calculation functions and got rid of all functions that take the output parameters with call-by-reference, additional information can be outut by local size-classes that derive from JKQTMathTextNodeSize, see e.g. JKQTMathTextSymbolNode::NodeSize and JKQTMathTextSymbolNode::getSymbolSize()
- NEW: JKQTMathTextVerticalListNode allows to typeset a vertical list of lines
- NEW: JKQTMathText::parse() by default allows linebreaks in the LaTeX string to be parsed. This can be switched off by a parameter
- NEW: added functions to set the font-size in pixels (as alternative to the existing functions that set them in points), implements request #76 from user:igormironchik
- NEW: reworked drawing of decorations: improved appearance and positioning!
- NEW: additional method JKQTMathtext::getSizeDetail() that returns all size-properties as a convenient struct, also added matching varinat JKQTMathTextNode::getSize()
- NEW: additional method JKQTMathtext::drawIntoPixmap(), JKQTMathtext::drawIntoPicture(), JKQTMathtext::drawIntoImage() which returns a QPixmap, QPicture and QImage respectively that contains the render result of the currently parsed markup
- NEW: array/tabular-environments have limited support for formatting string like \c l|r|c and for \c \\hline , \c \\hdashline , \c \\toprule , \c \\midrule , \c \\bottomrule
- NEW: reworked code structure: broke up large, single CPP-files into several smaller files!
- NEW: reworked node class tree: inserted base-class nodes for single-child, dual-child!
- NEW: improved frac-rendering: font-scaling takes nesting-level into account, overall-rendering, sizes, if a brace surrounds a frac, the heights are equal above and below to center the brace , ...

The only exceptions are ellipses (and the derived arcs,pies,chords), which are always drawn as mathematical curves
