==========================================================================================================================================
|phoenix_title| **wx.MemoryFSHandler**
==========================================================================================================================================
This :ref:`wx.FileSystem` handler can store arbitrary data in memory stream and make them accessible via an URL.
It is particularly suitable for storing bitmaps from resources or included XPM files so that they can be used with HTML or :ref:`wx.html2.WebView`.
Filenames are prefixed with ``"memory:"`` , e.g. ``"memory:myfile.html"`` .
Example:
::
def OnAbout(self, event):
bcur = wx.BeginBusyCursor()
wx.FileSystem.AddHandler(wx.MemoryFSHandler)
wx.MemoryFSHandler.AddFile("logo.pcx", wx.Bitmap("logo.pcx", wx.BITMAP_TYPE_PCX))
wx.MemoryFSHandler.AddFile("about.htm",
"About: "
"")
dlg = wx.Dialog(self, -1, _("About"))
topsizer = wx.BoxSizer(wx.VERTICAL)
html = wx.html.HtmlWindow(dlg, size=wx.Size(380, 160), style=wx.HW_SCROLLBAR_NEVER)
html.SetBorders(0)
html.LoadPage("memory:about.htm")
html.SetSize(html.GetInternalRepresentation().GetWidth(),
html.GetInternalRepresentation().GetHeight())
topsizer.Add(html, 1, wx.ALL, 10)
topsizer.Add(wx.StaticLine(dlg, -1), 0, wx.EXPAND | wx.LEFT | wx.RIGHT, 10)
topsizer.Add(wx.Button(dlg, wx.ID_OK, "Ok"),
0, wx.ALL | wx.ALIGN_RIGHT, 15)
dlg.SetAutoLayout(True)
dlg.SetSizer(topsizer)
topsizer.Fit(dlg)
dlg.Centre()
dlg.ShowModal()
wx.MemoryFSHandler.RemoveFile("logo.pcx")
wx.MemoryFSHandler.RemoveFile("about.htm")

:meth:`~wx.MemoryFSHandler.__init__` Constructor.
:meth:`~wx.MemoryFSHandler.AddFile` Adds a file to the list of the files stored in memory.
:meth:`~wx.MemoryFSHandler.AddFileWithMimeType` Like :meth:`~MemoryFSHandler.AddFile` , but lets you explicitly specify added file's MIME type.
:meth:`~wx.MemoryFSHandler.RemoveFile` Removes a file from memory ``FS`` and frees the occupied memory.

.. class:: wx.MemoryFSHandler(FileSystemHandler)
**Possible constructors**::
MemoryFSHandler()
This FileSystem handler can store arbitrary data in memory stream
and make them accessible via an URL.
.. method:: __init__(self)
Constructor.
.. staticmethod:: AddFile(*args, **kw)
|overload| Overloaded Implementations:
**~~~**
**AddFile** `(filename, image, type)`
Adds a file to the list of the files stored in memory.
Stored data (bitmap, text or raw data) will be copied into private memory stream and available under name ``"memory:"`` + `filename`.
:param `filename`:
:type `filename`: string
:param `image`:
:type `image`: wx.Image
:param `type`:
:type `type`: wx.BitmapType
.. note::
you must use a `type` value (aka image format) that wxWidgets can save (e.g. ``JPG``, ``PNG``, see :ref:`wx.Image` documentation)!
.. seealso:: :meth:`AddFileWithMimeType`
**~~~**
**AddFile** `(filename, bitmap, type)`
Adds a file to the list of the files stored in memory.
Stored data (bitmap, text or raw data) will be copied into private memory stream and available under name ``"memory:"`` + `filename`.
:param `filename`:
:type `filename`: string
:param `bitmap`:
:type `bitmap`: wx.Bitmap
:param `type`:
:type `type`: wx.BitmapType
.. note::
you must use a `type` value (aka image format) that wxWidgets can save (e.g. ``JPG``, ``PNG``, see :ref:`wx.Image` documentation)!
.. seealso:: :meth:`AddFileWithMimeType`
**~~~**
**AddFile** `(filename, textdata)`
Adds a file to the list of the files stored in memory.
Stored data (bitmap, text or raw data) will be copied into private memory stream and available under name ``"memory:"`` + `filename`.
:param `filename`:
:type `filename`: string
:param `textdata`:
:type `textdata`: string
.. note::
you must use a `type` value (aka image format) that wxWidgets can save (e.g. ``JPG``, ``PNG``, see :ref:`wx.Image` documentation)!
.. seealso:: :meth:`AddFileWithMimeType`
**~~~**
**AddFile** `(filename, binarydata)`
Add a file from raw data in a python buffer compatible object.
**~~~**
.. staticmethod:: AddFileWithMimeType(*args, **kw)
|overload| Overloaded Implementations:
**~~~**
**AddFileWithMimeType** `(filename, textdata, mimetype)`
Like :meth:`AddFile` , but lets you explicitly specify added file's MIME type.
This version should be used whenever you know the MIME type, because it makes accessing the files faster.
:param `filename`:
:type `filename`: string
:param `textdata`:
:type `textdata`: string
:param `mimetype`:
:type `mimetype`: string
.. versionadded:: 2.8.5
.. seealso:: :meth:`AddFile`
**~~~**
**AddFileWithMimeType** `(filename, binarydata, mimetype)`
Add a file from raw data in a python buffer compatible object.
**~~~**
.. staticmethod:: RemoveFile(filename)
Removes a file from memory ``FS`` and frees the occupied memory.
:param `filename`:
:type `filename`: string
