## Description

InfTextGtkViewport is a helper object which, as long as it is alive, draws the location of the cursor of remote users into the scrollbar of a GtkScrolledWindow containing a GtkTextView.

The function `inf_text_gtk_viewport_set_active_user()` can be used to skip drawing the location of the user working locally on the document, if there is any.

See InfTextGtkView for drawing the cursor and selected region of remote users into a GtkTextView.

## Functions

### inf_text_gtk_viewport_new ()

    InfTextGtkViewport *
    inf_text_gtk_viewport_new (GtkScrolledWindow *scroll,
                               InfUserTable *user_table);

Creates a new InfTextGtkViewport for `scroll` . This draws the position of remote user's cursors into the scrollbars of `scroll` .

[constructor]

#### Parameters

scroll | A GtkScrolledWindow. |
user_table | The InfUserTable for the text session displayed in `viewport` . |

#### Returns

A new InfTextGtkViewport.

[transfer full]

### inf_text_gtk_viewport_get_scrolled_window ()

    GtkScrolledWindow *
    inf_text_gtk_viewport_get_scrolled_window
                                   (InfTextGtkViewport *viewport);

Returns the underlying GtkScrolledWindow.

#### Parameters

viewport | A InfTextGtkViewport. |

#### Returns

The InfTextGtkViewport's GtkScrolledWindow.

[transfer none]

### inf_text_gtk_viewport_get_user_table ()

    InfUserTable *
    inf_text_gtk_viewport_get_user_table (InfTextGtkViewport *viewport);

Returns the InfUserTable containing the users of the session the InfTextGtkViewport's GtkScrolledWindow is displaying.

#### Parameters

viewport | A InfTextGtkViewport. |

#### Returns

The InfTextGtkViewport's InfUserTable.

[transfer none]

### inf_text_gtk_viewport_set_active_user ()

    void
    inf_text_gtk_viewport_set_active_user (InfTextGtkViewport *viewport,
                                           InfTextUser *user);

Sets the user for which perspective to draw the viewport. The cursor position for teh active user is not draws since it is assumed that the viewport's "real" scrollbars match the active user's position.

#### Parameters

viewport | A InfTextGtkViewport. |
user | A user from `viewport` 's user table, or `NULL`. | [allow-none]

### inf_text_gtk_viewport_get_active_user ()

    InfTextUser *
    inf_text_gtk_viewport_get_active_user (InfTextGtkViewport *viewport);
