| 3 | The path list is a convenient way of storing a number of directories, and |
| 4 | when presented with a filename without a directory, searching for an existing file |
| 5 | in those directories. Storing the filename only in an application's files and |
| 6 | using a locally-defined list of directories makes the application and its files more |
| 7 | portable. |
| 8 | |
| 9 | Use the {\it wxFileNameFromPath} global function to extract the filename |
| 10 | from the path. |

| 27 | \membersection{wxPathList::wxPathList} |
| 28 | |
| 29 | \func{}{wxPathList}{\void} |
| 30 | |
| 31 | Constructor. |
| 32 | |
| 33 | \membersection{wxPathList::AddEnvList} |
| 34 | |
| 35 | \func{void}{AddEnvList}{\param{const wxString\& }{env\_variable}} |
| 36 | |
| 37 | Finds the value of the given environment variable, and adds all paths |
| 38 | to the path list. Useful for finding files in the PATH variable, for |
| 39 | example. |
| 40 | |
| 41 | \membersection{wxPathList::Add} |
| 42 | |
| 43 | \func{void}{Add}{\param{const wxString\& }{path}} |
| 44 | |
| 45 | Adds the given directory to the path list, but does not |
| 46 | check if the path was already on the list (use wxPathList::Member) |
| 47 | for this). |
| 48 | |
| 49 | \membersection{wxPathList::EnsureFileAccessible} |
| 50 | |
| 51 | \func{void}{EnsureFileAccessible}{\param{const wxString\& }{filename}} |
| 52 | |
| 53 | Given a full filename (with path), ensures that files in the same path |
| 54 | can be accessed using the pathlist. It does this by stripping the |
| 55 | filename and adding the path to the list if not already there. |
| 56 | |
| 57 | \membersection{wxPathList::FindAbsoluteValidPath} |
| 58 | |
| 59 | \func{wxString}{FindAbsoluteValidPath}{\param{const wxString\& }{file}} |
| 60 | |
| 61 | Searches for a full path for an existing file by appending {\it file} to |
| 62 | successive members of the path list. If the file exists, a temporary |
| 63 | pointer to the absolute path is returned. |
| 64 | |
| 65 | \membersection{wxPathList::FindValidPath} |
| 66 | |
| 67 | \func{wxString}{FindValidPath}{\param{const wxString\& }{file}} |
| 68 | |
| 69 | Searches for a full path for an existing file by appending {\it file} to |
| 70 | successive members of the path list. If the file exists, a temporary |
| 71 | pointer to the full path is returned. This path may be relative to the current |
| 72 | working directory. |
| 73 | |
| 74 | \membersection{wxPathList::Member} |
| 75 | |
| 76 | \func{bool}{Member}{\param{const wxString\& }{file}} |
| 77 | |
| 78 | TRUE if the path is in the path list (ignoring case). |
