MIME type under Unix, but under Windows it corresponds more to an extension than
to MIME type (in fact, several extensions may correspond to a file type). This
object may be created in several different ways: the program might know the file
The objects of this class are never created by the application code but are
returned by \helpref{wxMimeTypesManager::GetFileTypeFromMimeType}{wxmimetypesmanagergetfiletypefrommimetype} and
\helpref{wxMimeTypesManager::GetFileTypeFromExtension}{wxmimetypesmanagergetfiletypefromextension} methods.

-A brief remainder about what the MIME types are (see the RFC 1341 for more

-"text/plain") where the category is a basic indication of what a file is

+\membersection{MessageParameters class}\label{wxfiletypemessageparameters}
One of the most common usages of MIME is to encode an e-mail message. The MIME
type of the encoded message is an example of a {\it message parameter}. These
\begin{verbatim}
// provide the message parameters for the MIME type manager
-class MailMessageParamaters : public wxFileType::MessageParameters
+class MailMessageParameters : public wxFileType::MessageParameters
{
public:
- MailMessageParamaters(const wxString& filename,
+ MailMessageParameters(const wxString& filename,
const wxString& mimetype)
: wxFileType::MessageParameters(filename, mimetype)
{
\end{verbatim}
Now you only need to create an object of this class and pass it to, for example,
-\helpref{GetOpenCommand}{wxfiletypegetopencommand} like this:
+\rtfsp\helpref{GetOpenCommand}{wxfiletypegetopencommand} like this:
\begin{verbatim}
wxString command;
{
// we don't know how to handle such files...
}
-
\end{verbatim}
{\bf Windows:} As only the file name is used by the program associated with the
ever derive from MessageParameters class for a Windows-only program.
\membersection{wxFileType::wxFileType}\label{wxfiletypewxfiletype}

\func{}{wxFileType}{\void}
The default constructor is private because you should never create objects of
-this type: they are only returned by
-\helpref{wxMimeTypesManager}{wxmimetypesmanager} methods.

\membersection{wxFileType::\destruct{wxFileType}}\label{wxfiletypedtor}
-\func{}{\destruct{wxFileType}{\void}
+
+\func{}{\destruct{wxFileType}}{\void}
The destructor of this class is not virtual, so it should not be derived from.
\membersection{wxFileType::GetMimeType}\label{wxfiletypegetmimetype}
-\func{bool}{GetMimeType}{\param{wxString *}{mimeType}}
+
+\func{bool}{GetMimeType}{\param{wxString*}{ mimeType}}
If the function returns TRUE, the string pointed to by {\it mimeType} is filled
with full MIME type specification for this file type: for example, "text/plain".
+\membersection{wxFileType::GetMimeTypes}\label{wxfiletypegetmimetypes}
+
+\func{bool}{GetMimeType}{\param{wxArrayString\&}{ mimeTypes}}
+
+Same as \helpref{GetMimeType}{wxfiletypegetmimetype} but returns array of MIME
+types. This array will contain only one item in most cases but sometimes,
+notably under Unix with KDE, may contain more MIME types. This happens when
+one file extension is mapped to different MIME types by KDE, mailcap and
+mime.types.
+
\membersection{wxFileType::GetExtensions}\label{wxfiletypegetextensions}
-\func{bool}{GetExtensions}{\param{wxArrayString \&}{extensions}}
+
+\func{bool}{GetExtensions}{\param{wxArrayString\&}{ extensions}}
If the function returns TRUE, the array {\it extensions} is filled
with all extensions associated with this file type: for example, it may
function in the first place.
\membersection{wxFileType::GetIcon}\label{wxfiletypegeticon}
-\func{bool}{GetIcon}{\param{wxIcon *}{icon}}
+
+\func{bool}{GetIcon}{\param{wxIcon*}{ icon}}
If the function returns TRUE, the icon associated with this file type will be
created and assigned to the {\it icon} parameter.
-{\bf Unix:} This function always returns FALSE under Unix.
+{\bf Unix:} MIME manager gathers information about icons from GNOME
+and KDE settings and thus GetIcon's success depends on availability
+of these desktop environments.
\membersection{wxFileType::GetDescription}\label{wxfiletypegetdescription}
-\func{bool}{GetDescription}{\param{wxString *}{desc}}
+
+\func{bool}{GetDescription}{\param{wxString*}{ desc}}
If the function returns TRUE, the string pointed to by {\it desc} is filled
with a brief description for this file type: for example, "text document" for
the "text/plain" MIME type.
\membersection{wxFileType::GetOpenCommand}\label{wxfiletypegetopencommand}
-\func{bool}{GetOpenCommand}{\param{wxString *}{command},\param{MessageParameters \&}{params}}
+
+\func{bool}{GetOpenCommand}{\param{wxString*}{ command}, \param{MessageParameters\&}{ params}}
If the function returns TRUE, the string pointed to by {\it command} is filled
with the command which must be executed (see \helpref{wxExecute}{wxexecute}) in
retrieved from \helpref{MessageParameters}{wxfiletypemessageparameters} class.
\membersection{wxFileType::GetPrintCommand}\label{wxfiletypegetprintcommand}
-\func{bool}{GetPrintCommand}{\param{wxString *}{command},\param{MessageParameters \&}{params}}
+
+\func{bool}{GetPrintCommand}{\param{wxString*}{ command},\param{MessageParameters\&}{ params}}
If the function returns TRUE, the string pointed to by {\it command} is filled
with the command which must be executed (see \helpref{wxExecute}{wxexecute}) in
retrieved from \helpref{MessageParameters}{wxfiletypemessageparameters} class.
\membersection{wxFileType::ExpandCommand}\label{wxfiletypeexpandcommand}
-\func{static wxString}{ExpandCommand}{\param{const wxString \&}{command},\param{MessageParameters \&}{params}}
+
+\func{static wxString}{ExpandCommand}{\param{const wxString\&}{ command}, \param{MessageParameters\&}{ params}}
This function is primarly intended for GetOpenCommand and GetPrintCommand
usage but may be also used by the application directly if, for example, you want
to use some non default command to open the file.
The function replaces all occurences of
+
\twocolwidtha{7cm}
\begin{twocollist}\itemsep=0pt
\twocolitem{format specificator}{with}
\twocolitem{\%t}{the MIME type}
\twocolitem{\%\{param\}}{the value of the parameter {\it param}}
\end{twocollist}
+
using the MessageParameters object you pass to it.
If there is no '\%s' in the command string (and the string is not empty), it is
Unlike all other functions of this class, there is no error return for this
function.
