Cross-platform GUI Library in C for Windows, Linux and MacOS.
This is a fork of the GraphApp GUI library found at http://enchantia.com/software/graphapp/ It is a cross-platform GUI Library in C for Windows, Linux and MacOS but is easily adapted to C++. See the "Graphapp and C PlusPlus.txt" file for info about using this library with C++. This version of GraphApp has been updated to create 64-bit binaries on Windows, Linux and MacOS. If you want 32-bit Windows binaries, then download the original archive from Enchantia and build your binaries from those sources. MacOS users will need to ensure that they've installed XQuartz or other X window manager on the Mac in order to build and run the binaries properly. Pre-compiled Windows binaries and a static library for Windows users can be found in the "Windows Binaries" folder of this repository. This fork has also been successfully compiled using cygwin and Visual Studio versions 2010 thru 2019. Successful builds have also been completed under MacOS using the XCode command line tools and on Ubuntu 22.10. A progress-bar indicator has also been added to this fork which is not present in the original library.
The file dialogs that are part of GraphApp are very rudimentary and very ugly. I recommend using TinyFileDialogs found here:https://sourceforge.net/projects/tinyfiledialogs/files/ which also provide native file dialogs for the target system.
A complete reference manual can be found online at: http://enchantia.com/software/graphapp/doc/manual/index.html or in the https://github.com/ferrellsl/Graphapp/blob/master/graphapp_manual.pdf file in the root of this repository.

Windows Build:
To build Windows binaries from source using Visual Studio, open a Visual Studio x64 native tools command prompt. Go to the GraphApp directory and run the Build_MSVC.bat found there. Successful builds have been tested on Visual Studio 2010 thru 2019.
Linux Build:
Do not run the configure script. Linux users simply need to open a terminal window and move to the GraphApp/src folder and type: make
This will build the link library. To build some of the examples, just type make followed by the name of the example you want to build such as the alldemo example: make alldemo or the fastline example by typing: make fastline
Successful builds have been accomplished on Ubuntu 16 thru Ubuntu 22.10. I have not attempted builds on any other Linux distros.
MacOS Build
MacOS users will need to install the XCode command line tools prior to compiling. There is a MacOS makefile located in the src folder. Delete the Linux makefile and rename makefile.MacOS to makefile and then run make from the src folder. MacOS users will also need an XWindows manager such as XQuartz which can be found here: https://www.xquartz.org/
Custom Soft Fonts and UTF8 Fonts
GraphApp will use your system fonts by default but if you want UTF8 and custom soft fonts you'll want to copy the fonts folders found in the archive under GraphApp/fonts to a folder called "graphappfonts" in the root of the drive where you expect to run your binaries. This location can be changed or customized by editing line number 39 of fontutil.c found in the src/utility folder and rebuilding the library. Some of the examples and demos such as "blend" and "alldemo" will fail to run unless you've copied the aforementioned fonts to the location mentioned earlier.
