## Implemented Interfaces

InfTextFixlineBuffer implements InfBuffer and InfTextBuffer.

## Includes

    #include <libinftext/inf-text-fixline-buffer.h>

## Description

This class is a wrapper around another InfTextBuffer. It makes sure that the number of trailing empty lines in the underlying buffer is always fixed to a given number while it itself keeps track of the missing or additional lines. This can be used for example to keep the number of empty lines fixed on the client side even if lines are added and removed within a text session.

## Functions

### inf_text_fixline_buffer_new ()

    InfTextFixlineBuffer *
    inf_text_fixline_buffer_new (InfIo *io,
                                 InfTextBuffer *buffer,
                                 guint n_lines);

Creates a new InfTextFixlineBuffer which keeps the number of trailing lines of the given underlying buffer fixed to `n_lines` .

#### Parameters

io | A InfIo object to schedule timeouts. |
buffer | The underlying buffer for which to keep a fixed line count. |
n_lines | The number of lines to be kept fixed. |

#### Returns

A InfTextFixlineBuffer.

## Types and Values

### struct InfTextFixlineBuffer

    struct InfTextFixlineBuffer;

InfTextFixlineBuffer is an opaque data type. You should only access it via the public API functions.

### struct InfTextFixlineBufferClass

    struct InfTextFixlineBufferClass {
      GObjectClass parent_class;
    };
