Creates a file handler object.

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

By default, checks the extension.

Returns the encoding to use when saving a file.

If empty, a suitable encoding is chosen.

Returns the default extension to recognise.

Returns flags controlling how loading and saving is done.

Returns the name of the handler.

Returns the handler type.

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

Loads the buffer from a stream.

Not all handlers will implement file loading.

Loads the buffer from a file.

Saves the buffer to a stream.

Not all handlers will implement file saving.

Saves the buffer to a file.

Sets the encoding to use when saving a file.

If empty, a suitable encoding is chosen.

Sets the default extension to recognise.

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.

Sets the name of the handler.

Sets the handler type.

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