### simply include all necessary files
If you use QMake and simply want to include all necessary files into your project, include one of these `PRI`-files into your QMake Project:
- `jkqtplotter.pri` contains all files in this library, including `JKQtFastPlotter` and `JKQtMathText`
- `jkqtplotter.pri` contains all files in this library, including `JKQtFastPlotter` and `JKQTmathText`
- `jkqtfastplotter.pri` contains only those files from this directory which are necessary to build `JKQtFastPlotter`
- `jkqtmathtext.pri` contains only those files from this directory which are necessary to build `JKQtMathText`
- `jkqtmathtext.pri` contains only those files from this directory which are necessary to build `JKQTmathText`
### Build static libraries
In the directory [`../staticlib`](../staticlib) you will find several Project files that build a static library of the full JKQtPlotter (including JKQtFastPlotter and JKMathText), or of subsets of this library. You can then link against these libs in your project.

The class is designed to be as robust as possible and will still return some output, even if the equation contains some errors.
Nevertheless, several errors are detected while parsing. You can get a list of error messages using get_error_list() after calling parse().
Also parse() will return \c false if an error occured while parsing.
