◆ NormalizePath() [1/2]

wxString NormalizePath ( const wxFileName &  aFilePath,
const ENV_VAR_MAP aEnvVars,
const wxString &  aProjectPath 
)

Normalize a file path to an environmental variable, if possible.

Parameters
aFilePathis the full file path (path and file name) to be normalized.
aEnvVarsis an optional map of environmental variables to try substitution with.
aProjectPathis an optional string to normalize the file path to the project path.
Returns
Normalized full file path (path and file name) if succeeded or the input path if the path could not be normalized.
