This wxFileSystem handler can store arbitrary data in memory stream and make
|
|
|
|
|
them accessible via an URL.

2008-05-10 09:44:43 +00:00
|
|
|
It is particularly suitable for storing bitmaps from resources or included XPM
|
2012-09-11 09:26:58 +00:00
|
|
|
files so that they can be used with wxHTML or wxWebView.
|

|
|
|
|
|
|
|
|
Filenames are prefixed with @c "memory:", e.g. @c "memory:myfile.html".

This version should be used whenever you know the MIME type, because it
