virtual wxString wxHtmlTagHandler::GetSupportedTags

(

)

[pure virtual]

Returns list of supported tags.

The list is in uppercase and tags are delimited by ','. Example: "I,B,FONT,P"

virtual bool wxHtmlTagHandler::HandleTag

(

const wxHtmlTag &

tag

)

[pure virtual]

This is the core method of each handler.

It is called each time one of supported tags is detected. tag contains all necessary info (see wxHtmlTag for details).

例:

        bool MyHandler::HandleTag(const wxHtmlTag& tag)
        {
            ...
            // change state of parser (e.g. set bold face)
            ParseInner(tag);
            ...
            // restore original state of parser
        }

You shouldn't call ParseInner() if the tag is not paired with an ending one.

Returns:

true if ParseInner() was called, false otherwise.

void wxHtmlTagHandler::ParseInner

(

const wxHtmlTag &

tag

)

[protected]

This method calls parser's wxHtmlParser::DoParsing method for the string between this tag and the paired ending tag:

        ...<A HREF="x.htm">Hello, world!</A>...

In this example, a call to ParseInner() (with tag pointing to A tag) will parse 'Hello, world!'.

virtual void wxHtmlTagHandler::SetParser

(

wxHtmlParser *

parser

)

[virtual]

Assigns parser to this handler.

Each instance of handler is guaranteed to be called only from the parser.
