@class wxRichTextHTMLHandler
|
|
@headerfile richtexthtml.h wx/richtext/richtexthtml.h
|
|
|
|
Handles HTML output (only) for wxRichTextCtrl content.
|
|
|
|
The most flexible way to use this class is to create a temporary object and call
|
|
its functions directly, rather than use wxRichTextBuffer::SaveFile or
|
|
wxRichTextCtrl::SaveFile.
|
|
|
|
Image handling requires a little extra work from the application, to choose an
|
|
appropriate image format for the target HTML viewer and to clean up the
|
|
temporary images
|
|
later. If you are planning to load the HTML into a standard web browser, you can
|
|
specify the handler flag wxRICHTEXT_HANDLER_SAVE_IMAGES_TO_BASE64 (the default)
|
|
and no extra work is required: the images will be written with the HTML.
|
|
|
|
However, if you want wxHTML compatibility, you will need to use
|
|
wxRICHTEXT_HANDLER_SAVE_IMAGES_TO_MEMORY
|
|
or wxRICHTEXT_HANDLER_SAVE_IMAGES_TO_FILES. In this case, you must either call
|
|
wxRichTextHTMLHandler::DeleteTemporaryImages before
|
|
the next load operation, or you must store the image
|
|
locations and delete them yourself when appropriate. You can call
|
|
wxRichTextHTMLHandler::GetTemporaryImageLocations to
|
|
get the array of temporary image names.
