7
8This \helpref{wxFileSystem}{wxfilesystem} handler can store arbitrary
9data in memory stream and make them accessible via URL. It is particularly
10suitable for storing bitmaps from resources or included XPM files so that
11they can be used with wxHTML.
12
13Filenames are prefixed with "memory:", e.g. "memory:myfile.html".
14
15Example:
16
17\begin{verbatim}
18#ifndef __WXMSW__
19#include "logo.xpm"
20#endif
21
22void 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();

77
78Constructor.

83
84\func{static void}{AddFile}{\param{const wxString\& }{filename}, \param{const wxBitmap\& }{bitmap}, \param{long }{type}}
85
86Add file to list of files stored in memory. Stored
87data (bitmap, text or raw data)
88will be copied into private memory stream and available under
89name "memory:" + \arg{filename}.
90
91The \arg{type} argument is one of {\tt wxBITMAP\_TYPE\_XXX} constants.
92Note that you must use a \arg{type} value (aka image format)
93that wxWidgets can save (e.g. JPG, PNG, see \helpref{wxImage
94documentation}{wximage})!

106
107Like \helpref{AddFile}{wxmemoryfshandleraddfile}, but lets you explicitly
108specify added file's MIME type. This version should be used whenever you know
109the MIME type, because it makes accessing the files faster.
