\section{\class{wxDir}}\label{wxdir}
|
||
|
|
|
||
|
|
wxDir is a portable equivalent of Unix {open/read/close}dir functions which
|
||
|
|
allow enumerating of the files in a directory. wxDir allows enumerate files as
|
||
|
|
well as directories.
|
||
|
|
|
||
|
|
Example of use:
|
||
|
|
|
||
|
|
\begin{verbatim}
|
||
|
|
wxDir dir(wxGetCwd());
|
||
|
|
|
||
|
|
if ( !dir.IsOpened() )
|
||
|
|
{
|
||
|
|
// deal with the error here - wxDir would already log an error message
|
||
|
|
// explaining the exact reason of the failure
|
||
|
|
return;
|
||
|
|
}
|
||
|
|
|
||
|
|
puts("Enumerating object files in current directory:");
|
||
|
|
|
||
|
|
wxString filename;
|
||
|
|
|
||
|
|
bool cont = dir.GetFirst(&filename, filespec, flags);
|
||
|
|
while ( cont )
|
||
|
|
{
|
||
|
|
printf("%s\n", filename.c_str());
|
||
|
|
|
||
|
|
cont = dir.GetNext(&filename);
|
||
|
|
}
|
||
|
|
\end{verbatim}
|
||
|
|
|
||
|
|
\wxheading{Derived from}
|
||
|
|
|
||
|
|
No base class
|
||
|
|
|
||
|
|
\wxheading{Constants}
|
||
|
|
|
||
|
|
These flags define what kind of filenames is included in the list of files
|
||
|
|
enumerated by GetFirst/GetNext
|
||
|
|
|
||
|
|
{\small
|
||

\membersection{wxDir::Exists}\label{wxdirexists}
|
||
|
|
|
||
|
|
\func{static bool}{Exists}{\param{const wxString\& }{dir}}
|
||
|
|
|
||
|
|
Test for existence of a directory with the given name
|
||
|
|
|
||
|
|
\membersection{wxDir::wxDir}\label{wxdirwxdir}
|
||
|
|
|
||
|
|
\func{}{wxDir}{\void}
|
||
|
|
|
||
|
|
Default constructor, use \helpref{Open()}{wxdiropen} afterwards.
|
||
|
|
|
||
|
|
\func{}{wxDir}{\param{const wxString\& }{dir}}
|
||
|
|
|
||
|
|
Opens the directory for enumeration, use \helpref{IsOpened()}{wxdirisopened}
|
||
|
|
to test for errors.
|
||
|
|
|
||
|
|
\membersection{wxDir::\destruct{wxDir}}\label{wxdirdtor}
|
||
|
|
|
||
|
|
\func{}{\destruct{wxDir}}{\void}
|
||
|
|
|
||
|
|
Destructor cleans up the associated ressources. It is not virtual and so this
|
||
|
|
class is not meant to be used polymorphically.
|
||
|
|
|
||
|
|
\membersection{wxDir::Open}\label{wxdiropen}
|
||
|
|
|
||
|
|
\func{bool}{Open}{\param{const wxString\& }{dir}}
|
||
|
|
|
||
|
|
Open the directory for enumerating, returns TRUE on success or FALSE if an
|
||
|
|
error occured.
|
||
|
|
|
||
|
|
\membersection{wxDir::IsOpened}\label{wxdirisopened}
|
||
|
|
|
||
|
|
\constfunc{bool}{IsOpened}{\void}
|
||
|
|
|
||
|
|
Returns TRUE if the directory was successfully opened by a previous call to
|
||
|
|
\helpref{Open}{wxdiropen}.
|
||
|
|
|
||
|
|
\membersection{wxDir::GetFirst}\label{wxdirgetfirst}
|
||
|
|
|
||
|
|
\constfunc{bool}{GetFirst}{\param{wxString* }{filename}, \param{const wxString\& }{filespec = wxEmptyString}, \param{int }{flags = wxDIR\_DEFAULT}}
|
||
|
|
|
||
|
|
Start enumerating all files matching {\it filespec} (or all files if it is
|
||
|
|
empty) and flags, return TRUE on success.
|
||
|
|
|
||
|
|
\membersection{wxDir::GetNext}\label{wxdirgetnext}
|
||
|
|
|
||
|
|
\constfunc{bool}{GetNext}{\param{wxString* }{filename}}
|
||
|
|
|
||
|
|
Continue enumerating files satisfying the criteria specified by the last call
|
||
|
|
to \helpref{GetFirst}{wxdirgetfirst}.
