phoenix_title wx.MemoryFSHandler

This 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 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",
                               "<html><body>About: "
                               "<img src=\"memory:logo.pcx\"></body></html>")

    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")

static 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.

Parameters:

Note

you must use a type value (aka image format) that wxWidgets can save (e.g. JPG, PNG, see wx.Image documentation)!
