◆ CanRead()

virtual bool wxHtmlFilter::CanRead ( const wxFSFile file) const

bool MyFilter::CanRead(const wxFSFile& file)
{
return (file.GetMimeType() == "application/x-ugh");
}
This class represents a single file opened by wxFileSystem.
Definition: filesys.h:204
const wxString & GetMimeType() const
Returns the MIME type of the content of this file.

◆ ReadFile()

virtual wxString wxHtmlFilter::ReadFile ( const wxFSFile file) const
pure virtual

Reads the file and returns string with HTML document.

Example:

wxString MyImgFilter::ReadFile(const wxFSFile& file)
{
return "<html><body><img src=\"" + file.GetLocation() +
"\"></body></html>";
}
const wxString & GetLocation() const
Returns full location of the file, including path and protocol.
String class for passing textual data to or receiving it from wxWidgets.
