## Description

## Functions

### gtk_label_new ()

    GtkWidget *
    gtk_label_new (const gchar *str);

Creates a new label with the given text inside it. You can pass `NULL` to get an empty label widget.

#### Parameters

str | The text of the label |

#### Returns

the new GtkLabel

### gtk_label_set_text ()

    void
    gtk_label_set_text (GtkLabel *label,
                        const gchar *str);

Sets the text within the GtkLabel widget. It overwrites any text that was there before.

This will also clear any previously set mnemonic accelerators.

#### Parameters

label | a GtkLabel |
str | The text you want to set |

### gtk_label_set_attributes ()

    void
    gtk_label_set_attributes (GtkLabel *label,
                              PangoAttrList *attrs);

Sets a PangoAttrList; the attributes in the list are applied to the label text.

The attributes set with this function will be applied and merged with any other attributes previously effected by way of the “use-underline” or “use-markup” properties. While it is not recommended to mix markup strings with manually set attributes, if you must; know that the attributes will be applied to the label after the markup string is parsed.

#### Parameters

label | a GtkLabel |
attrs | a PangoAttrList |

### gtk_label_set_markup ()

    void
    gtk_label_set_markup (GtkLabel *label,
                          const gchar *str);

Parses `str` which is marked up with the Pango text markup language, setting the label's text and attribute list based on the parse results. If the `str` is external data, you may need to escape it with `g_markup_escape_text()` or `g_markup_printf_escaped()`:

    1
    2
    3
    4
    5
    char *markup;

    markup = g_markup_printf_escaped ("<span style=\"italic\">%s</span>", str);
    gtk_label_set_markup (GTK_LABEL (label), markup);
    g_free (markup);

#### Parameters

label | a GtkLabel |
str | a markup string (see Pango markup format) |

### gtk_label_set_markup_with_mnemonic ()

    void
    gtk_label_set_markup_with_mnemonic (GtkLabel *label,
                                        const gchar *str);

Parses `str` which is marked up with the Pango text markup language, setting the label's text and attribute list based on the parse results. If characters in `str` are preceded by an underscore, they are underlined indicating that they represent a keyboard accelerator called a mnemonic.

The mnemonic key can be used to activate another widget, chosen automatically, or explicitly using `gtk_label_set_mnemonic_widget()`.

#### Parameters

label | a GtkLabel |
str | a markup string (see Pango markup format) |

### gtk_label_set_pattern ()

    void
    gtk_label_set_pattern (GtkLabel *label,
                           const gchar *pattern);

### gtk_label_set_justify ()

    void
    gtk_label_set_justify (GtkLabel *label,
                           GtkJustification jtype);

Sets the alignment of the lines in the text of the label relative to each other. `GTK_JUSTIFY_LEFT` is the default value when the widget is first created with `gtk_label_new()`. If you instead want to set the alignment of the label as a whole, use `gtk_misc_set_alignment()` instead. `gtk_label_set_justify()` has no effect on labels containing only a single line.

#### Parameters

label | a GtkLabel |
jtype | a GtkJustification |

### gtk_label_set_ellipsize ()

    void
    gtk_label_set_ellipsize (GtkLabel *label,
                             PangoEllipsizeMode mode);

Sets the mode used to ellipsize (add an ellipsis: "...") to the text if there is not enough space to render the entire string.

#### Parameters

label | a GtkLabel |
mode | a PangoEllipsizeMode |

Since: 2.6

### gtk_label_set_width_chars ()

    void
    gtk_label_set_width_chars (GtkLabel *label,
                               gint n_chars);

Sets the desired width in characters of `label` to `n_chars` .

#### Parameters

label | a GtkLabel |
n_chars | the new desired width, in characters. |

Since: 2.6

### gtk_label_set_max_width_chars ()

    void
    gtk_label_set_max_width_chars (GtkLabel *label,
                                   gint n_chars);

Sets the desired maximum width in characters of `label` to `n_chars` .

#### Parameters

label | a GtkLabel |
n_chars | the new desired maximum width, in characters. |

Since: 2.6

### gtk_label_get ()

    void
    gtk_label_get (GtkLabel *label,
                   gchar **str);

`gtk_label_get` is deprecated and should not be used in newly-written code.

### gtk_label_parse_uline ()

    guint
    gtk_label_parse_uline (GtkLabel *label,
                           const gchar *string);

`gtk_label_parse_uline` is deprecated and should not be used in newly-written code.

### gtk_label_set_line_wrap ()

    void
    gtk_label_set_line_wrap (GtkLabel *label,
                             gboolean wrap);

Toggles line wrapping within the GtkLabel widget. `TRUE` makes it break lines if text exceeds the widget's size. `FALSE` lets the text get cut off by the edge of the widget if it exceeds the widget size.

Note that setting line wrapping to `TRUE` does not make the label wrap at its parent container's width, because GTK+ widgets conceptually can't make their requisition depend on the parent container's size. For a label that wraps at a specific position, set the label's width using `gtk_widget_set_size_request()`.

#### Parameters

label | a GtkLabel |
wrap | the setting |

### gtk_label_set_line_wrap_mode ()

    void
    gtk_label_set_line_wrap_mode (GtkLabel *label,
                                  PangoWrapMode wrap_mode);

If line wrapping is on (see `gtk_label_set_line_wrap()`) this controls how the line wrapping is done. The default is `PANGO_WRAP_WORD` which means wrap on word boundaries.

#### Parameters

label | a GtkLabel |
wrap_mode | the line wrapping mode |

Since: 2.10

### gtk_label_get_layout_offsets ()

    void
    gtk_label_get_layout_offsets (GtkLabel *label,
                                  gint *x,
                                  gint *y);

Obtains the coordinates where the label will draw the PangoLayout representing the text in the label; useful to convert mouse events into coordinates inside the PangoLayout, e.g. to take some action if some part of the label is clicked. Of course you will need to create a GtkEventBox to receive the events, and pack the label inside it, since labels are a GTK_NO_WINDOW widget. Remember when using the PangoLayout functions you need to convert to and from pixels using `PANGO_PIXELS()` or PANGO_SCALE.

#### Parameters

label | a GtkLabel |
x | location to store X offset of layout, or `NULL`. | [out][allow-none]
y | location to store Y offset of layout, or `NULL`. | [out][allow-none]

### gtk_label_get_mnemonic_keyval ()

    guint
    gtk_label_get_mnemonic_keyval (GtkLabel *label);

If the label has been set so that it has an mnemonic key this function returns the keyval used for the mnemonic accelerator. If there is no mnemonic set up it returns GDK_VoidSymbol.

#### Parameters

label | a GtkLabel |

#### Returns

GDK keyval usable for accelerators, or GDK_VoidSymbol

### gtk_label_get_selectable ()

    gboolean
    gtk_label_get_selectable (GtkLabel *label);

Gets the value set by `gtk_label_set_selectable()`.

#### Parameters

label | a GtkLabel |

#### Returns

`TRUE` if the user can copy text from the label

### gtk_label_get_text ()

    const gchar *
    gtk_label_get_text (GtkLabel *label);

Fetches the text from a label widget, as displayed on the screen. This does not include any embedded underlines indicating mnemonics or Pango markup. (See `gtk_label_get_label()`)

#### Parameters

label | a GtkLabel |

#### Returns

the text in the label widget. This is the internal string used by the label, and must not be modified.

### gtk_label_new_with_mnemonic ()

    GtkWidget *
    gtk_label_new_with_mnemonic (const gchar *str);

Creates a new GtkLabel, containing the text in `str` .

If characters in `str` are preceded by an underscore, they are underlined. If you need a literal underscore character in a label, use '__' (two underscores). The first underlined character represents a keyboard accelerator called a mnemonic. The mnemonic key can be used to activate another widget, chosen automatically, or explicitly using `gtk_label_set_mnemonic_widget()`.

If `gtk_label_set_mnemonic_widget()` is not called, then the first activatable ancestor of the GtkLabel will be chosen as the mnemonic widget. For instance, if the label is inside a button or menu item, the button or menu item will automatically become the mnemonic widget and be activated by the mnemonic.

#### Parameters

str | The text of the label, with an underscore in front of the mnemonic character |

#### Returns

the new GtkLabel

### gtk_label_select_region ()

    void
    gtk_label_select_region (GtkLabel *label,
                             gint start_offset,
                             gint end_offset);

Selects a range of characters in the label, if the label is selectable. See `gtk_label_set_selectable()`. If the label is not selectable, this function has no effect. If `start_offset` or `end_offset` are -1, then the end of the label will be substituted.

#### Parameters

label | a GtkLabel |
start_offset | start offset (in characters not bytes) |
end_offset | end offset (in characters not bytes) |

### gtk_label_set_mnemonic_widget ()

    void
    gtk_label_set_mnemonic_widget (GtkLabel *label,
                                   GtkWidget *widget);

If the label has been set so that it has an mnemonic key (using i.e. `gtk_label_set_markup_with_mnemonic()`, `gtk_label_set_text_with_mnemonic()`, `gtk_label_new_with_mnemonic()` or the "use_underline" property) the label can be associated with a widget that is the target of the mnemonic. When the label is inside a widget (like a GtkButton or a GtkNotebook tab) it is automatically associated with the correct widget, but sometimes (i.e. when the target is a GtkEntry next to the label) you need to set it explicitly using this function.

The target widget will be accelerated by emitting the GtkWidget::mnemonic-activate signal on it. The default handler for this signal will activate the widget if there are no mnemonic collisions and toggle focus between the colliding widgets otherwise.

#### Parameters

label | a GtkLabel |
widget | the target GtkWidget. | [allow-none]

### gtk_label_set_selectable ()

    void
    gtk_label_set_selectable (GtkLabel *label,

#### Parameters

label | a GtkLabel |
setting | `TRUE` to allow selecting text in the label |

### gtk_label_set_text_with_mnemonic ()

    void

                                      const gchar *str);

Sets the label's text from the string `str` . If characters in `str` are preceded by an underscore, they are underlined indicating that they represent a keyboard accelerator called a mnemonic. The mnemonic key can be used to activate another widget, chosen automatically, or explicitly using `gtk_label_set_mnemonic_widget()`.

#### Parameters

label | a GtkLabel |
str | a string |

### gtk_label_get_attributes ()

    PangoAttrList *
    gtk_label_get_attributes (GtkLabel *label);

Gets the attribute list that was set on the label using `gtk_label_set_attributes()`, if any. This function does not reflect attributes that come from the labels markup (see `gtk_label_set_markup()`). If you want to get the effective attributes for the label, use pango_layout_get_attribute (gtk_label_get_layout (label)).

#### Parameters

label | a GtkLabel |

The current position of the insertion cursor in chars.

Flags: Read

Allowed values: >= 0

Default value: 0

### The `“ellipsize”` property

      “ellipsize”                PangoEllipsizeMode

The preferred place to ellipsize the string, if the label does not have enough room to display the entire string, specified as a PangoEllisizeMode.

Note that setting this property to a value other than `PANGO_ELLIPSIZE_NONE` has the side-effect that the label requests only enough space to display the ellipsis "...". In particular, this means that ellipsizing labels do not work well in notebook tabs, unless the tab's “tab-expand” property is set to `TRUE`. Other ways to set a label's width are `gtk_widget_set_size_request()` and `gtk_label_set_width_chars()`.

Flags: Read / Write

Default value: PANGO_ELLIPSIZE_NONE

Since: 2.6

### The `“justify”` property

      “justify”                  GtkJustification

The alignment of the lines in the text of the label relative to each other. This does NOT affect the alignment of the label within its allocation. See GtkMisc::xalign for that.

Flags: Read / Write

Default value: GTK_JUSTIFY_LEFT

### The `“label”` property

      “label”                    gchar *

The text of the label.

Flags: Read / Write

Default value: ""

### The `“max-width-chars”` property

      “max-width-chars”          gint

The desired maximum width of the label, in characters. If this property is set to -1, the width will be calculated automatically, otherwise the label will request space for no more than the requested number of characters. If the “width-chars” property is set to a positive value, then the "max-width-chars" property is ignored.

Flags: Read / Write

Allowed values: >= -1

Default value: -1

Since: 2.6

### The `“mnemonic-keyval”` property

      “mnemonic-keyval”          guint

Default value: 0

### The `“single-line-mode”` property

      “single-line-mode”         gboolean

Whether the label is in single line mode. In single line mode, the height of the label does not depend on the actual text, it is always set to ascent + descent of the font. This can be an advantage in situations where resizing the label because of text changes would be distracting, e.g. in a statusbar.

Flags: Read / Write

Default value: FALSE

Since: 2.6

### The `“track-visited-links”` property

      “track-visited-links”      gboolean

Set this property to `TRUE` to make the label track which links have been clicked. It will then apply the ::visited-link-color color, instead of ::link-color.

Flags: Read / Write

Default value: TRUE

Since: 2.18

### The `“use-markup”` property

Flags: Read / Write

Default value: FALSE

### The `“width-chars”` property

      “width-chars”              gint

The desired width of the label, in characters. If this property is set to -1, the width will be calculated automatically, otherwise the label will request either 3 characters or the property value, whichever is greater. If the "width-chars" property is set to a positive value, then the “max-width-chars” property is ignored.

Flags: Read / Write

Allowed values: >= -1

Default value: -1

Since: 2.6

### The `“wrap”` property

      “wrap”                     gboolean

If set, wrap lines if the text becomes too wide.

Flags: Read / Write

Default value: FALSE

### The `“wrap-mode”` property

      “wrap-mode”                PangoWrapMode

If line wrapping is on (see the “wrap” property) this controls how the line wrapping is done. The default is `PANGO_WRAP_WORD`, which means wrap on word boundaries.

Flags: Read / Write

Default value: PANGO_WRAP_WORD

Since: 2.10

## Signal Details

### The `“activate-current-link”` signal

    void
    user_function (GtkLabel *label,
                   gpointer  user_data)

A keybinding signal which gets emitted when the user activates a link in the label.

Applications may also emit the signal with `g_signal_emit_by_name()` if they need to control activation of URIs programmatically.

The default bindings for this signal are all forms of the Enter key.

#### Parameters

label | The label on which the signal was emitted |
user_data | user data set when the signal handler was connected. |

Flags: Action

Since: 2.18

### The `“activate-link”` signal

    gboolean
    user_function (GtkLabel *label,
                   gchar    *uri,
                   gpointer  user_data)

The signal which gets emitted to activate a URI. Applications may connect to it to override the default behaviour, which is to call `gtk_show_uri()`.

#### Parameters

label | The label on which the signal was emitted |
uri | the URI that is activated |
user_data | user data set when the signal handler was connected. |

#### Returns

`TRUE` if the link has been activated

Flags: Run Last

Since: 2.18

### The `“copy-clipboard”` signal

    void
    user_function (GtkLabel *label,
                   gpointer  user_data)

The ::copy-clipboard signal is a

keybinding signal

which gets emitted to copy the selection to the clipboard.

The default binding for this signal is Ctrl-c.

#### Parameters

label | the object which received the signal |
user_data | user data set when the signal handler was connected. |

Flags: Action

### The `“move-cursor”` signal

    void
    user_function (GtkLabel       *entry,
                   GtkMovementStep step,
                   gint            count,
                   gboolean        extend_selection,
                   gpointer        user_data)

The ::move-cursor signal is a

keybinding signal

which gets emitted when the user initiates a cursor movement. If the cursor is not visible in `entry` , this signal causes the viewport to be moved instead.

Applications should not connect to it, but may emit it with `g_signal_emit_by_name()` if they need to control the cursor programmatically.

The default bindings for this signal come in two variants, the variant with the Shift modifier extends the selection, the variant without the Shift modifer does not. There are too many key combinations to list them all here.

- Arrow keys move by individual characters/lines
- Ctrl-arrow key combinations move by words/paragraphs
- Home/End keys move to the ends of the buffer

#### Parameters

entry | the object which received the signal |
step | the granularity of the move, as a GtkMovementStep |
count | the number of `step` units to move |
extend_selection | `TRUE` if the move should extend the selection |
user_data | user data set when the signal handler was connected. |

Flags: Action

### The `“populate-popup”` signal

    void
    user_function (GtkLabel *label,
                   GtkMenu  *menu,
                   gpointer  user_data)

The ::populate-popup signal gets emitted before showing the context menu of the label. Note that only selectable labels have context menus.

If you need to add items to the context menu, connect to this signal and append your menuitems to the `menu` .

#### Parameters

label | The label on which the signal is emitted |
menu | the menu that is being populated |
user_data | user data set when the signal handler was connected. |
