## Constructor & Destructor Documentation

wxRichTextFileHandler::wxRichTextFileHandler | ( | const wxString & | name = `wxEmptyString`,
|  | const wxString & | ext = `wxEmptyString`,
|  | int | type = `0`
| ) |  |
| inline

Creates a file handler object.

## Member Function Documentation

virtual bool wxRichTextFileHandler::CanHandle | ( | const wxString & | filename | ) | const
| virtual

Returns true if we handle this filename (if using files).

By default, checks the extension.

virtual bool wxRichTextFileHandler::CanLoad | ( |  | ) | const
| inlinevirtual

Returns true if we can load using this handler.

Reimplemented in wxRichTextPlainTextHandler, and wxRichTextXMLHandler.

virtual bool wxRichTextFileHandler::CanSave | ( |  | ) | const
| inlinevirtual

Returns true if we can save using this handler.

Reimplemented in wxRichTextPlainTextHandler, and wxRichTextXMLHandler.

virtual bool wxRichTextFileHandler::DoLoadFile | ( | wxRichTextBuffer * | buffer,
|  | wxInputStream & | stream
| ) |  |
| protectedpure virtual

Override to load content from stream into buffer.

Implemented in wxRichTextPlainTextHandler, and wxRichTextXMLHandler.

virtual bool wxRichTextFileHandler::DoSaveFile | ( | wxRichTextBuffer * | buffer,
|  | wxOutputStream & | stream
| ) |  |
| protectedpure virtual

Override to save content to stream from buffer.

Implemented in wxRichTextPlainTextHandler, wxRichTextHTMLHandler, and wxRichTextXMLHandler.

const wxString& wxRichTextFileHandler::GetEncoding | ( |  | ) | const
| inline

Returns the encoding to use when saving a file.

If empty, a suitable encoding is chosen.

wxString wxRichTextFileHandler::GetExtension | ( |  | ) | const
| inline

Returns the default extension to recognise.

int wxRichTextFileHandler::GetFlags | ( |  | ) | const
| inline

Returns flags controlling how loading and saving is done.

wxString wxRichTextFileHandler::GetName | ( |  | ) | const
| inline

Returns the name of the handler.

int wxRichTextFileHandler::GetType | ( |  | ) | const
| inline

Returns the handler type.

virtual bool wxRichTextFileHandler::IsVisible | ( |  | ) | const
| inlinevirtual

Returns true if this handler should be visible to the user.

bool wxRichTextFileHandler::LoadFile | ( | wxRichTextBuffer * | buffer,
|  | wxInputStream & | stream
| ) |  |
| inline

Loads the buffer from a stream.

Not all handlers will implement file loading.

virtual bool wxRichTextFileHandler::LoadFile | ( | wxRichTextBuffer * | buffer,
|  | const wxString & | filename
| ) |  |
| virtual

Loads the buffer from a file.

bool wxRichTextFileHandler::SaveFile | ( | wxRichTextBuffer * | buffer,
|  | wxOutputStream & | stream
| ) |  |
| inline

Saves the buffer to a stream.

Not all handlers will implement file saving.

virtual bool wxRichTextFileHandler::SaveFile | ( | wxRichTextBuffer * | buffer,
|  | const wxString & | filename
| ) |  |
| virtual

Saves the buffer to a file.

void wxRichTextFileHandler::SetEncoding | ( | const wxString & | encoding | ) |
| inline

Sets the encoding to use when saving a file.

If empty, a suitable encoding is chosen.

void wxRichTextFileHandler::SetExtension | ( | const wxString & | ext | ) |
| inline

Sets the default extension to recognise.

void wxRichTextFileHandler::SetFlags | ( | int | flags | ) |
| inline

Sets flags that change the behaviour of loading or saving.

See the documentation for each handler class to see what flags are relevant for each handler.

You call this function directly if you are using a file handler explicitly (without going through the text control or buffer LoadFile/SaveFile API). Or, you can call the control or buffer's SetHandlerFlags function to set the flags that will be used for subsequent load and save operations.

void wxRichTextFileHandler::SetName | ( | const wxString & | name | ) |
| inline

Sets the name of the handler.

void wxRichTextFileHandler::SetType | ( | int | type | ) |
| inline

Sets the handler type.

virtual void wxRichTextFileHandler::SetVisible | ( | bool | visible | ) |
| inlinevirtual

Sets whether the handler should be visible to the user (via the application's load and save dialogs).
