## Description

The GtkLabel widget displays a small amount of text. As the name implies, most labels are used to label another widget such as a GtkButton, a GtkMenuItem, or a GtkOptionMenu.

### Mnemonics

Labels may contain mnemonics. Mnemonics are underlined characters in the label, used for keyboard navigation. Mnemonics are created by providing a string with an underscore before the mnemonic character, such as `"_File"`, to the functions `gtk_label_new_with_mnemonic()` or `gtk_label_set_text_with_mnemonic()`.

Mnemonics automatically activate any activatable widget the label is inside, such as a GtkButton; if the label is not inside the mnemonic's target widget, you have to tell the label about the target using `gtk_label_set_mnemonic_widget()`. Here's a simple example where the label is inside a button:

      /* Pressing Alt+H will activate this button */
      button = gtk_button_new ();
      label = gtk_label_new_with_mnemonic ("_Hello");
      gtk_container_add (GTK_CONTAINER (button), label);

There's a convenience function to create buttons with a mnemonic label already inside:

      /* Pressing Alt+H will activate this button */
      button = gtk_button_new_with_mnemonic ("_Hello");

To create a mnemonic for a widget alongside the label, such as a GtkEntry, you have to point the label at the entry with `gtk_label_set_mnemonic_widget()`:

      /* Pressing Alt+H will focus the entry */
      entry = gtk_entry_new ();
      label = gtk_label_new_with_mnemonic ("_Hello");
      gtk_label_set_mnemonic_widget (GTK_LABEL (label), entry);

### Markup (styled text)

To make it easy to format text in a label (changing colors, fonts, etc.), label text can be provided in a simple markup format. Here's how to create a label with a small font:

      label = gtk_label_new (NULL);
      gtk_label_set_markup (GTK_LABEL (label), "<small>Small text</small>");

(See complete documentation of available tags in the Pango manual.)

The markup passed to `gtk_label_set_markup()` must be valid; for example, literal </>/& characters must be escaped as &lt;, &gt;, and &amp;. If you pass text obtained from the user, file, or a network to `gtk_label_set_markup()`, you'll want to escape it with `g_markup_escape_text()` or `g_markup_printf_escaped()`.

Markup strings are just a convenient way to set the PangoAttrList on a label; `gtk_label_set_attributes()` may be a simpler way to set attributes in some cases. Be careful though; PangoAttrList tends to cause internationalization problems, unless you're applying attributes to the entire string (i.e. unless you set the range of each attribute to [0, G_MAXINT)). The reason is that specifying the start_index and end_index for a PangoAttribute requires knowledge of the exact string being displayed, so translations will cause problems.

### Selectable labels

Labels can be made selectable with `gtk_label_set_selectable()`. Selectable labels allow the user to copy the label contents to the clipboard. Only labels that contain useful-to-copy information — such as error messages — should be made selectable.

### Text layout

A label can contain any number of paragraphs, but will have performance problems if it contains more than a small number. Paragraphs are separated by newlines or other paragraph separators understood by Pango.

Labels can automatically wrap text if you call `gtk_label_set_line_wrap()`.

`gtk_label_set_justify()` sets how the lines in a label align with one another. If you want to set how the label as a whole aligns in its available space, see `gtk_misc_set_alignment()`.

## Details

### GtkLabel

    typedef struct _GtkLabel GtkLabel;

This should not be accessed directly. Use the accessor functions as described below.

### 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.

`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.

`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 ignored if the "use_underline" property or the "use_markup" property is `TRUE`.

`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()`:

    char *markup;

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

`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()`.

`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);

The pattern of underlines you want under the existing text within the GtkLabel widget. For example if the current text of the label says "FooBarBaz" passing a pattern of "___ ___" will underline "Foo" and "Baz" but not "Bar".

`label` : | The GtkLabel you want to set the pattern to.
`pattern` : | The pattern as described above.

### 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.

`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.

`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`.

`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`.

`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);

### Warning

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

Gets the current string of text within the GtkLabel and writes it to the given `str` argument. It does not make a copy of this string so you must not write to it.

`label` : | The GtkLabel widget you want to get the text from.
`str` : | The reference to the pointer you want to point to the text.

### gtk_label_parse_uline ()

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

### Warning

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

Parses the given string for underscores and converts the next character to an underlined character. The last character that was underlined will have its lower-cased accelerator keyval returned (i.e. "_File" would return the keyval for "f". This is probably only used within the Gtk+ library itself for menu items and such.

`label` : | The GtkLabel you want to affect.
`string` : | The string you want to parse for underlines.
Returns : | The lowercase keyval of the last character underlined.

### 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.

`label` : | a GtkLabel
`wrap` : | the setting

### gtk_label_set

    #define  gtk_label_set           gtk_label_set_text

### Warning

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

Aliases `gtk_label_set_text()`. Probably used for backward compatibility with Gtk+ 1.0.x.

### 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.

`label` : | a GtkLabel
`x` : | location to store X offset of layout, or `NULL`
`y` : | location to store Y offset of layout, or `NULL`

### 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.

`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()`.

`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()`)

`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.

`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.

`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 "mnemonic_activate" 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.

`label` : | a GtkLabel
`widget` : | the target GtkWidget

### gtk_label_set_selectable ()

    void        gtk_label_set_selectable        (GtkLabel *label,

Selectable labels allow the user to select text from the label, for copy-and-paste.

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

### gtk_label_set_text_with_mnemonic ()

    void        gtk_label_set_text_with_mnemonic
                                                (GtkLabel *label,
                                                 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()`.

`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)).

`label` : | a GtkLabel
Returns : | the attribute list, or `NULL` if none was set.

### gtk_label_get_justify ()

### gtk_label_get_layout ()

    PangoLayout* gtk_label_get_layout           (GtkLabel *label);

Gets the PangoLayout used to display the label. The layout is useful to e.g. convert text positions to pixel positions, in combination with `gtk_label_get_layout_offsets()`. The returned layout is owned by the label so need not be freed by the caller.

`label` : | a GtkLabel
Returns : | the PangoLayout for this label

### gtk_label_get_line_wrap ()

    gboolean    gtk_label_get_line_wrap         (GtkLabel *label);

`angle` : | the angle that the baseline of the label makes with the horizontal, in degrees, measured counterclockwise

Since 2.6

## Property Details

### The "`angle`" property

      "angle"                gdouble               : Read / Write

The angle that the baseline of the label makes with the horizontal, in degrees, measured counterclockwise. An angle of 90 reads from from bottom to top, an angle of 270, from top to bottom. Ignored if the label is selectable, wrapped, or ellipsized.

Allowed values: [0,360]

Default value: 0

Since 2.6

### The "`attributes`" property

      "attributes"           PangoAttrList         : Read / Write

A list of style attributes to apply to the text of the label.

### The "`cursor-position`" property

      "cursor-position"      gint                  : Read

The current position of the insertion cursor in chars.

Allowed values: >= 0

Default value: 0

### The "`ellipsize`" property

      "ellipsize"            PangoEllipsizeMode    : Read / Write

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 don't work well in notebook tabs, unless the tab's ::tab-expand property is set to `TRUE`. Other means to set a label's width are `gtk_widget_set_size_request()` and `gtk_label_set_width_chars()`.

Default value: PANGO_ELLIPSIZE_NONE

Since 2.6

### The "`justify`" property

      "justify"              GtkJustification      : Read / Write

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.

Default value: GTK_JUSTIFY_LEFT

### The "`label`" property

      "label"                gchararray            : Read / Write

The text of the label.

Default value: NULL

### The "`max-width-chars`" property

      "max-width-chars"      gint                  : Read / Write

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.

Allowed values: >= -1

Default value: -1

Since 2.6

### The "`mnemonic-keyval`" property

      "mnemonic-keyval"      guint                 : Read

The mnemonic accelerator key for this label.

Default value: 16777215

### The "`mnemonic-widget`" property

      "mnemonic-widget"      GtkWidget             : Read / Write

The widget to be activated when the label's mnemonic key is pressed.

### The "`pattern`" property

      "pattern"              gchararray            : Write

A string with _ characters in positions correspond to characters in the text to underline.

Default value: NULL

### The "`selectable`" property

### The "`single-line-mode`" property

      "single-line-mode"     gboolean              : Read / Write

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.

Default value: FALSE

Since 2.6

### The "`use-markup`" property

      "use-markup"           gboolean              : Read / Write

The text of the label includes XML markup. See pango_parse_markup().

Default value: FALSE

### The "`use-underline`" property

      "use-underline"        gboolean              : Read / Write

If set, an underline in the text indicates the next character should be used for the mnemonic accelerator key.

Default value: FALSE

### The "`width-chars`" property

      "width-chars"          gint                  : Read / Write

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.

Allowed values: >= -1

Default value: -1

Since 2.6

### The "`wrap`" property

      "wrap"                 gboolean              : Read / Write
