wxUSE Preprocessor Symbols

This section documents the wxUSE preprocessor symbols used in the wxWidgets source, grouped by category (and sorted by alphabetical order inside each category).

These symbols are always defined and whether the given feature is active or not depends on their value: if defined as `1`, feature is active, otherwise it is disabled. Because of this these symbols should always be tested using #if and not #ifdef.

# Most Important Symbols

This table summarizes some of the global build features affecting the entire library:

wxUSE_STL | Container classes and wxString are implemented using standard classes and provide the same standard API.
wxUSE_STD_STRING | wxString is implemented using std::[w]string and can be constructed from it (but provides wxWidgets-compatible API, in particular is implicitly convertible to `char*` and not std::[w]string).
wxUSE_STD_IOSTREAM | Standard C++ classes are used instead of or in addition to wx stream classes.
wxUSE_UNICODE | Compiled with Unicode support (default in wxWidgets 3.0, non-Unicode build will be deprecated in the future).
wxUSE_UNICODE_WCHAR | wxString uses wchar_t buffer for internal storage (default under MSW).
wxUSE_UNICODE_UTF8 | wxString uses UTF-8 for internal storage (default under Unix and Mac systems).
wxUSE_UTF8_LOCALE_ONLY | Library supports running only under UTF-8 (and C) locale. This eliminates the code necessary for conversions from the other locales and reduces the library size; useful for embedded systems.
wxUSE_GUI | Use the GUI classes; if set to 0 only non-GUI classes are available.
