@class wxMemoryFSHandler
|
|
@wxheader{fs_mem.h}
|
|
|
|
This 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:
|
|
|
|
@code
|
|
#ifndef __WXMSW__
|
|
#include "logo.xpm"
|
|
#endif
|
|

|
|

|
|
"htmlbodyAbout: "
|
|
"img src=\"memory:logo.pcx\"/body/html");
|

|

|
|

|
|
