Opening header files

To open a header file, right-click the file's name in the Outline view (for example, stdio.h) and choose Open in the context menu.

Many of the enhanced source navigation (including opening header files) and code development accelerators available in the C/C++ editor are extracted from the source code. To enable these features and provide the most accurate data representation, you must configure the project with the include paths and define directives used to compile the source.

For QNX projects, the include paths and define directives are set automatically based on the compiler and architecture. You can set additional values in the QNX C/C++ Project properties.

For C/C++ Makefile projects, you must define the values yourself through the project's properties, as explained in "Setting the include paths and define directives".
