b0df7a1fd7 NEW/BREAKING: provide general targets JKQTPlotter5/6::JKQTPlotter5/6, JKQTPlotter5/6::JKQTMathText5/6, ... which are independent of the type of build (shared/static) 
NEW/BREAKING: refactor CMake-Code, so static/dynamic switch is done via <code>BUILD_SHARED_LIBS</code>, which retires <code>JKQtPlotter_BUILD_STATIC_LIBS</code>, <code>JKQtPlotter_BUILD_SHARED_LIBS</code> and removes the capability to build static and shared libraries in one location (fixes issue #104)
NEW: prepareed library for CMake's <a href="https://cmake.org/cmake/help/latest/module/FetchContent.html">FetchContent</a>-API
NEW: the different sub-libraries JKQTPlotter, JKQTFastPlotter (DEPRECATED), JKQTMath, JKQTMathText can be activated/deactivated with CMake options JKQtPlotter_BUILD_LIB_JKQTPLOTTER, JKQtPlotter_BUILD_LIB_JKQTFASTPLOTTER, JKQtPlotter_BUILD_LIB_JKQTMATHTEXT, JKQtPlotter_BUILD_LIB_JKQTMATH

09e07cb12a NEW/REWORKED: extended the set of functions like JKQTMathTextGetTightBoundingRect(): These use an internal, thread-safe cache and capsule calls to QFontMetricsF-instances. This significantly improves speed in (parallelized) plotting. 2024-01-08 17:16:31 +01:00

9662ed2d69 MODIFIED: Synchronization of JKQTMathText and JKQTBasePlotter over threads: using read/write lockers now and removed some unnecessary mutexes by using a kind of singleton pattern 2024-01-05 23:26:47 +01:00

aa2fcb108d NEW/REWORKED JKQTBasePlottercan be used is re-entrant, i.e. different instances can be used from different threads in parallel (although there is significant overhead due to shared caches between the threads!). 
NEW added multithreaded example to demonstrate using JKQTBasePlotter in several parallel threads
