	6	\section{\class{wxMemoryFSHandler}}\label{wxmemoryfshandler}
	7
	8	This \helpref{wxFileSystem}{wxfilesystem} handler can store arbitrary
	9	data in memory stream and make them accessible via URL. It is particularly
	10	suitable for storing bitmaps from resources or included XPM files so that
	11	they can be used with wxHTML.
	12
	13	Filenames are prefixed with "memory:", e.g. "memory:myfile.html".
	14
	15	Example:
	16
	17	\begin{verbatim}
	18	#ifndef __WXMSW__
	19	#include "logo.xpm"
	20	#endif
	21
	22	void MyFrame::OnAbout(wxCommandEvent&)
	23	{
	24	wxBusyCursor bcur;
	25	wxFileSystem::AddHandler(new wxMemoryFSHandler);
	26	wxMemoryFSHandler::AddFile("logo.pcx", wxBITMAP(logo), wxBITMAP_TYPE_PCX);
	27	wxMemoryFSHandler::AddFile("about.htm",
	28	"<html><body>About: "
	29	"<img src=\"memory:logo.pcx\"></body></html>");
	30
	31	wxDialog dlg(this, -1, wxString(_("About")));
	32	wxBoxSizer *topsizer;
	33	wxHtmlWindow *html;
	34	topsizer = new wxBoxSizer(wxVERTICAL);
	35	html = new wxHtmlWindow(&dlg, -1, wxDefaultPosition,
	36	wxSize(380, 160), wxHW_SCROLLBAR_NEVER);
	37	html->SetBorders(0);
	38	html->LoadPage("memory:about.htm");
	39	html->SetSize(html->GetInternalRepresentation()->GetWidth(),
	40	html->GetInternalRepresentation()->GetHeight());
	41	topsizer->Add(html, 1, wxALL, 10);
	42	topsizer->Add(new wxStaticLine(&dlg, -1), 0, wxEXPAND \| wxLEFT \| wxRIGHT, 10);
	43	topsizer->Add(new wxButton(&dlg, wxID_OK, "Ok"),
	44	0, wxALL \| wxALIGN_RIGHT, 15);
	45	dlg.SetAutoLayout(true);
	46	dlg.SetSizer(topsizer);
	47	topsizer->Fit(&dlg);
	48	dlg.Centre();
	49	dlg.ShowModal();

	52	wxMemoryFSHandler::RemoveFile("about.htm");

	78
	79	\func{static void}{AddFile}{\param{const wxString\& }{filename}, \param{const wxBitmap\& }{bitmap}, \param{long }{type}}
	80
	81	Add file to list of files stored in memory. Stored
	82	data (bitmap, text or raw data)
	83	will be copied into private memory stream and available under
	84	name "memory:" + \arg{filename}.
	85
	86	The \arg{type} argument is one of {\tt wxBITMAP\_TYPE\_XXX} constants.
	87	Note that you must use a \arg{type} value (aka image format)
	88	that wxWidgets can save (e.g. JPG, PNG, see \helpref{wxImage
	89	documentation}{wximage})!

	101
	102	Like \helpref{AddFile}{wxmemoryfshandleraddfile}, but lets you explicitly
	103	specify added file's MIME type. This version should be used whenever you know
	104	the MIME type, because it makes accessing the files faster.
