\section{\class{wxMemoryFSHandler}}\label{wxmemoryfshandler}
|
|
|
|
This \helpref{wxFileSystem}{wxfilesystem} handler can store arbitrary
|
|
data in memory stream and make them accessible via URL. It is particularly
|
|
suitable for storing bitmaps from resources or included XPM files so that
|
|
they can be used with wxHTML.
|
|
|
|
Filenames are prefixed with "memory:", e.g. "memory:myfile.html".
|
|
|
|
Example:
|
|
|
|
\begin{verbatim}
|
|
#ifndef __WXMSW__
|
|
#include "logo.xpm"
|
|
#endif
|
|
|
|
void MyFrame::OnAbout(wxCommandEvent&)
|
|
{
|
|
wxBusyCursor bcur;
|
|
wxFileSystem::AddHandler(new wxMemoryFSHandler);
|
|
wxMemoryFSHandler::AddFile("logo.pcx", wxBITMAP(logo), wxBITMAP_TYPE_PCX);
|
|
wxMemoryFSHandler::AddFile("about.htm",
|
|
"<html><body>About: "
|
|
"<img src=\"memory:logo.pcx\"></body></html>");
|
|
|
|
wxDialog dlg(this, -1, wxString(_("About")));
|
|
wxBoxSizer *topsizer;
|
|
wxHtmlWindow *html;
|
|
topsizer = new wxBoxSizer(wxVERTICAL);
|
|
html = new wxHtmlWindow(&dlg, -1, wxDefaultPosition,
|
|
wxSize(380, 160), wxHW_SCROLLBAR_NEVER);
|
|
html->SetBorders(0);
|
|
html->LoadPage("memory:about.htm");
|
|
html->SetSize(html->GetInternalRepresentation()->GetWidth(),
|
|
html->GetInternalRepresentation()->GetHeight());
|
|
topsizer->Add(html, 1, wxALL, 10);
|
|
topsizer->Add(new wxStaticLine(&dlg, -1), 0, wxEXPAND | wxLEFT | wxRIGHT, 10);
|
|
topsizer->Add(new wxButton(&dlg, wxID_OK, "Ok"),
|
|
0, wxALL | wxALIGN_RIGHT, 15);
|
|
dlg.SetAutoLayout(true);
|
|
dlg.SetSizer(topsizer);
|
|
topsizer->Fit(&dlg);
|
|
dlg.Centre();
|
|
dlg.ShowModal();
|
|
|
|
wxMemoryFSHandler::RemoveFile("logo.pcx");
|

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

\membersection{wxMemoryFSHandler::RemoveFile}\label{wxmemoryfshandlerremovefile}
|
|
|
|
\func{static void}{RemoveFile}{\param{const wxString\& }{filename}}
|
|
|
|
Remove file from memory FS and free occupied memory.
