## Implemented Interfaces

TeplTab implements AtkImplementorIface, GtkBuildable, GtkOrientable and TeplTabGroup.

## Includes

    #include <tepl/tepl.h>

## Description

TeplTab is meant to be the content of one tab in the text editor (if the text editor has a Tabbed Document Interface). It is a GtkGrid container that contains the TeplView and can contain one or several GtkInfoBar's. Since it is a GtkGrid, an application can of course add any other widget to it.

To create a new GtkInfoBar, it is recommended to use TeplInfoBar (but TeplTab doesn't enforce it).

By default:

- TeplTab has a vertical GtkOrientation.

- The main child widget of TeplTab is a GtkScrolledWindow which contains the TeplView.

- GtkInfoBar's are added on top of the GtkScrolledWindow.

The way that the TeplView is packed into the TeplTab is customizable with the ::pack_view virtual function. Similarly, the way that GtkInfoBar's are added can be customized with ::pack_info_bar.

### TeplTabGroup implementation

TeplTab implements the TeplTabGroup interface, for a group of only one tab. It is useful for text editors that open each file in a separate window, or for applications that don't require to open more than one file. But the `tepl_tab_group_append_tab()` operation is not supported, so some higher-level features of Tepl don't work with TeplTab as the TeplTabGroup of the window. This will maybe be improved in the future by creating automatically a new window.

## Functions

### tepl_tab_new ()

    TeplTab *
    tepl_tab_new (void);

Creates a new TeplTab with a new TeplView. The new TeplView can be retrieved afterwards with `tepl_tab_get_view()`.

a new TeplTab.

Since: 3.0

### tepl_tab_new_with_view ()

    TeplTab *
    tepl_tab_new_with_view (TeplView *view);

### tepl_tab_get_buffer ()

    TeplBuffer *
    tepl_tab_get_buffer (TeplTab *tab);

A convenience function that calls `gtk_text_view_get_buffer()` on the “view” associated with the `tab` .

the TeplBuffer of the “view”.

[transfer none]

Since: 3.0

the TeplGotoLineBar widget belonging to `tab` .

[transfer none]

Since: 5.0

### tepl_tab_add_info_bar ()

    void
    tepl_tab_add_info_bar (TeplTab *tab,
                           GtkInfoBar *info_bar);

Attaches `info_bar` to `tab` .

This function calls the ::pack_info_bar virtual function.

#### Parameters

info_bar | a GtkInfoBar. |

Since: 1.0

### tepl_tab_load_file ()

    void
    tepl_tab_load_file (TeplTab *tab,
                        GFile *location);

Unconditionally loads a file in `tab` , regardless if there are unsaved changes in the GtkTextBuffer. The previous buffer content is lost.

This function is asynchronous, there is no way to know when the file loading is finished.

#### Parameters

tab | a TeplTab. |
location | a GFile. |

Since: 4.0

### tepl_tab_save_async ()

    void
    tepl_tab_save_async (TeplTab *tab,

                         gpointer user_data);

Saves asynchronously the content of the `tab` . The “location” must not be `NULL`.

See the GAsyncResult documentation to know how to use this function.

#### Parameters

tab | a TeplTab. |
callback | a GAsyncReadyCallback to call when the request is satisfied. | [scope async]
user_data | user data to pass to `callback` . |

Since: 4.0

### tepl_tab_save_finish ()

    gboolean
    tepl_tab_save_finish (TeplTab *tab,
                          GAsyncResult *result);

Finishes a tab saving started with `tepl_tab_save_async()`.

#### Parameters

tab | a TeplTab. |
result | a GAsyncResult. |

#### Returns

whether the tab was saved successfully.

Since: 4.0

### tepl_tab_save_async_simple ()

    void
    tepl_tab_save_async_simple (TeplTab *tab);

The same as `tepl_tab_save_async()`, but without callback.

This function is useful when you don't need to know:

- when the operation is finished;

- and whether the operation ran successfully.

#### Parameters

tab | a TeplTab. |

Since: 4.0

### tepl_tab_save_as_async ()

    void
    tepl_tab_save_as_async (TeplTab *tab,

                            gpointer user_data);

Shows a GtkFileChooser to save the `tab` to a different location, creates an appropriate TeplFileSaver and asynchronously runs it.

See the GAsyncResult documentation to know how to use this function.

#### Parameters

tab | a TeplTab. |
callback | a GAsyncReadyCallback to call when the request is satisfied. | [scope async]

## Types and Values

### struct TeplTab

    struct TeplTab;

### struct TeplTabClass

    struct TeplTabClass {
    	GtkGridClass parent_class;

    	/* Vfuncs */

    	void (* pack_view)		(TeplTab  *tab,
    					 TeplView *view);

    	void (* pack_info_bar) (TeplTab    *tab,
    					 GtkInfoBar *info_bar);

    	void (* pack_goto_line_bar) (TeplTab         *tab,
    					 TeplGotoLineBar *goto_line_bar);

    	/* Signals */

    	void (* close_request) (TeplTab *tab);
    };

#### Members

`pack_view` () | Virtual function pointer to add the TeplView in the TeplTab container. Called only once at object construction time, when the “view” property is set. By default the TeplView is added to a GtkScrolledWindow and the GtkScrolledWindow is added to the TeplTab with `gtk_container_add()`. |
`pack_info_bar` () | Virtual function pointer to add a GtkInfoBar in the TeplTab container. By default the GtkInfoBar is inserted just above the GtkScrolledWindow containing the TeplView. |
`pack_goto_line_bar` () | Virtual function pointer to add a TeplGotoLineBar in the TeplTab container. By default the TeplGotoLineBar is added at the bottom. |
`close_request` () | For the “close-request” signal. |

## Property Details

### The `“view”` property

      “view”                     TeplView *

The TeplView contained in the tab. When this property is set, the ::pack_view virtual function is called.

Owner: TeplTab

Flags: Read / Write / Construct Only

Since: 3.0

## Signal Details

### The `“close-request”` signal

    void
    user_function (TeplTab *tab,
                   gpointer user_data)

The ::close-request signal is emitted when there is a request to close the TeplTab, for example if the user clicks on a close button.

The default object method handler does the following:

- If the buffer is not modified (according to `gtk_text_buffer_get_modified()`), close the tab.

- Else, show a message dialog to propose to save the file before closing.

To override the default object method handler, either override the virtual function in a TeplTab subclass or connect to the signal and call `g_signal_stop_emission_by_name()`.

#### Parameters

tab | the TeplTab emitting the signal. |
user_data | user data set when the signal handler was connected. |

Flags: Run Last

Since: 3.0
