/// Displays a small amount of text.
///
/// Most labels are used to label another widget (such as an [`Entry`][crate::Entry]).
///
/// ![An example GtkLabel](label.png)
///
/// ## Shortcuts and Gestures
///
/// [`Label`][crate::Label] supports the following keyboard shortcuts, when the cursor is
/// visible:
///
/// - <kbd>Shift</kbd>+<kbd>F10</kbd> or <kbd>Menu</kbd> opens the context menu.
/// - <kbd>Ctrl</kbd>+<kbd>A</kbd> or <kbd>Ctrl</kbd>+<kbd>/</kbd>
/// selects all.
/// - <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>A</kbd> or
/// <kbd>Ctrl</kbd>+<kbd>\</kbd> unselects all.
///
/// Additionally, the following signals have default keybindings:
///
/// - [`activate-current-link`][struct@crate::Label#activate-current-link]
/// - [`copy-clipboard`][struct@crate::Label#copy-clipboard]
/// - [`move-cursor`][struct@crate::Label#move-cursor]
///
/// ## Actions
///
/// [`Label`][crate::Label] defines a set of built-in actions:
///
/// - `clipboard.copy` copies the text to the clipboard.
/// - `clipboard.cut` doesn't do anything, since text in labels can't be deleted.
/// - `clipboard.paste` doesn't do anything, since text in labels can't be
/// edited.
/// - `link.open` opens the link, when activated on a link inside the label.
/// - `link.copy` copies the link to the clipboard, when activated on a link
/// inside the label.
/// - `menu.popup` opens the context menu.
/// - `selection.delete` doesn't do anything, since text in labels can't be
/// deleted.
/// - `selection.select-all` selects all of the text, if the label allows
/// selection.
///
/// ## CSS nodes
///
/// ```text
/// label
/// ├── [selection]
/// ├── [link]
/// ┊
/// ╰── [link]
/// ```
///
/// [`Label`][crate::Label] has a single CSS node with the name label. A wide variety
/// of style classes may be applied to labels, such as .title, .subtitle,
/// .dim-label, etc. In the [`ShortcutsWindow`][crate::ShortcutsWindow], labels are used with the
/// .keycap style class.
///
/// If the label has a selection, it gets a subnode with name selection.
///
/// If the label has links, there is one subnode per link. These subnodes
/// carry the link or visited state depending on whether they have been
/// visited. In this case, label node also gets a .link style class.
///
/// ## GtkLabel as GtkBuildable
///
/// The GtkLabel implementation of the GtkBuildable interface supports a
/// custom `<attributes>` element, which supports any number of `<attribute>`
/// elements. The `<attribute>` element has attributes named “name“, “value“,
/// “start“ and “end“ and allows you to specify `Pango::Attribute`
/// values for this label.
///
/// An example of a UI definition fragment specifying Pango attributes:
///
/// ```xml
/// <object class="GtkLabel">
/// <attributes>
/// <attribute name="weight" value="PANGO_WEIGHT_BOLD"/>
/// <attribute name="background" value="red" start="5" end="10"/>
/// </attributes>
/// </object>
/// ```
///
/// The start and end attributes specify the range of characters to which the
/// Pango attribute applies. If start and end are not specified, the attribute is
/// applied to the whole text. Note that specifying ranges does not make much
/// sense with translatable attributes. Use markup embedded in the translatable
/// content instead.
///
/// ## Accessibility
///
/// [`Label`][crate::Label] uses the [enum@Gtk.AccessibleRole.label] role.
///
/// ## 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 [`with_mnemonic()`][Self::with_mnemonic()] or
/// [`set_text_with_mnemonic()`][Self::set_text_with_mnemonic()].
///
/// Mnemonics automatically activate any activatable widget the label is
/// inside, such as a [`Button`][crate::Button]; if the label is not inside the
/// mnemonic’s target widget, you have to tell the label about the target
/// using [`set_mnemonic_widget()`][Self::set_mnemonic_widget()].
///
/// Here’s a simple example where the label is inside a button:
///
/// **⚠️ The following code is in c ⚠️**
///
/// ```c
/// // Pressing Alt+H will activate this button
/// GtkWidget *button = gtk_button_new ();
/// GtkWidget *label = gtk_label_new_with_mnemonic ("_Hello");
/// gtk_button_set_child (GTK_BUTTON (button), label);
/// ```
///
/// There’s a convenience function to create buttons with a mnemonic label
/// already inside:
///
/// **⚠️ The following code is in c ⚠️**
///
/// ```c
/// // Pressing Alt+H will activate this button
/// GtkWidget *button = gtk_button_new_with_mnemonic ("_Hello");
/// ```
///
/// To create a mnemonic for a widget alongside the label, such as a
/// [`Entry`][crate::Entry], you have to point the label at the entry with
/// [`set_mnemonic_widget()`][Self::set_mnemonic_widget()]:
///
/// **⚠️ The following code is in c ⚠️**
///
/// ```c
/// // Pressing Alt+H will focus the entry
/// GtkWidget *entry = gtk_entry_new ();
/// GtkWidget *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:
/// **⚠️ The following code is in c ⚠️**
///
/// ```c
/// GtkWidget *label = gtk_label_new (NULL);
/// gtk_label_set_markup (GTK_LABEL (label), "<small>Small text</small>");
/// ```
///
/// (See the Pango manual for complete documentation] of available
/// tags, `parse_markup()`)
///
/// The markup passed to [`set_markup()`][Self::set_markup()] must be valid XML; for example,
/// literal `<`, `>` and `&` characters must be escaped as `<`, `>`, and `&`.
/// If you pass text obtained from the user, file, or a network to
/// [`set_markup()`][Self::set_markup()], you’ll want to escape it with
/// `markup_escape_text()` or `markup_printf_escaped()`.
///
/// Markup strings are just a convenient way to set the [`pango::AttrList`][crate::pango::AttrList]
/// on a label; [`set_attributes()`][Self::set_attributes()] may be a simpler way to set
/// attributes in some cases. Be careful though; [`pango::AttrList`][crate::pango::AttrList] 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 `Pango::Attribute` requires knowledge of the exact
/// string being displayed, so translations will cause problems.
///
/// ## Selectable labels
///
/// Labels can be made selectable with [`set_selectable()`][Self::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 [`set_wrap()`][Self::set_wrap()].
///
/// [`set_justify()`][Self::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 the [`halign`][struct@crate::Widget#halign] and
/// [`valign`][struct@crate::Widget#valign] properties.
///
/// The [`width-chars`][struct@crate::Label#width-chars] and [`max-width-chars`][struct@crate::Label#max-width-chars]
/// properties can be used to control the size allocation of ellipsized or
/// wrapped labels. For ellipsizing labels, if either is specified (and less
/// than the actual text size), it is used as the minimum width, and the actual
/// text size is used as the natural width of the label. For wrapping labels,
/// width-chars is used as the minimum width, if specified, and max-width-chars
/// is used as the natural width. Even if max-width-chars specified, wrapping
/// labels will be rewrapped to use all of the available width.
///
/// ## Links
///
/// GTK supports markup for clickable hyperlinks in addition to regular Pango
/// markup. The markup for links is borrowed from HTML, using the `<a>` tag
/// with “href“, “title“ and “class“ attributes. GTK renders links similar to
/// the way they appear in web browsers, with colored, underlined text. The
/// “title“ attribute is displayed as a tooltip on the link. The “class“
/// attribute is used as style class on the CSS node for the link.
///
/// An example of inline links looks like this:
///
/// **⚠️ The following code is in c ⚠️**
///
/// ```c
/// const char *text =
/// "Go to the "
/// "<a href=\"https://www.gtk.org\" title=\"<i>Our</i> website\">"
/// "GTK website</a> for more...";
/// GtkWidget *label = gtk_label_new (NULL);
/// gtk_label_set_markup (GTK_LABEL (label), text);
/// ```
///
/// It is possible to implement custom handling for links and their tooltips
/// with the [`activate-link`][struct@crate::Label#activate-link] signal and the
/// [`current_uri()`][Self::current_uri()] function.
///
/// ## Properties
///
///
/// #### `attributes`
/// A list of style attributes to apply to the text of the label.
///
/// Readable | Writeable
///
///
/// #### `ellipsize`
/// The preferred place to ellipsize the string, if the label does
/// not have enough room to display the entire string.
///
/// Note that setting this property to a value other than
/// [enum.Pango.EllipsizeMode.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-expand`][struct@crate::NotebookPage#tab-expand] child property is set to true.
///
/// Other ways to set a label's width are [`WidgetExt::set_size_request()`][crate::prelude::WidgetExt::set_size_request()]
/// and [`Label::set_width_chars()`][crate::Label::set_width_chars()].
///
/// Readable | Writeable
///
///
/// #### `extra-menu`
/// A menu model whose contents will be appended to the context menu.
///
/// Readable | Writeable
///
///
/// #### `justify`
/// 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 [`xalign`][struct@crate::Label#xalign] for that.
///
/// Readable | Writeable
///
///
/// #### `label`
/// The contents of the label.
///
/// If the string contains Pango markup (see `parse_markup()`),
/// you will have to set the [`use-markup`][struct@crate::Label#use-markup] property to
/// true in order for the label to display the markup attributes. See also
/// [`Label::set_markup()`][crate::Label::set_markup()] for a convenience function that sets both
/// this property and the [`use-markup`][struct@crate::Label#use-markup] property at the
/// same time.
///
/// If the string contains underlines acting as mnemonics, you will have to
/// set the [`use-underline`][struct@crate::Label#use-underline] property to true in order
/// for the label to display them.
///
/// Readable | Writeable
///
///
/// #### `lines`
/// The number of lines to which an ellipsized, wrapping label
/// should be limited.
///
/// This property has no effect if the label is not wrapping or ellipsized.
///
/// Set this property to -1 if you don't want to limit the number of lines.
///
/// Readable | Writeable
///
///
/// #### `max-width-chars`
/// The desired maximum width of the label, in characters.
///
/// If this property is set to -1, the width will be calculated automatically.
///
/// See the section on [text layout](class.Label.html#text-layout) for details
/// of how [`width-chars`][struct@crate::Label#width-chars] and [`max-width-chars`][struct@crate::Label#max-width-chars]
/// determine the width of ellipsized and wrapped labels.
///
/// Readable | Writeable
///
///
/// #### `mnemonic-keyval`
/// The mnemonic accelerator key for the label.
///
/// Readable
///
///
/// #### `mnemonic-widget`
/// The widget to be activated when the labels mnemonic key is pressed.
///
/// Readable | Writeable
///
///
/// #### `natural-wrap-mode`
/// Select the line wrapping for the natural size request.
///
/// This only affects the natural size requested. For the actual wrapping
/// used, see the [`wrap-mode`][struct@crate::Label#wrap-mode] property.
///
/// The default is [enum@Gtk.NaturalWrapMode.inherit], which inherits
/// the behavior of the [`wrap-mode`][struct@crate::Label#wrap-mode] property.
///
/// Readable | Writeable
///
///
/// #### `selectable`
/// Whether the label text can be selected with the mouse.
///
/// Readable | Writeable
///
///
/// #### `single-line-mode`
/// 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.
///
/// Readable | Writeable
///
///
/// #### `tabs`
/// Custom tabs for this label.

///
/// #### `use-markup`

/// #### `width-chars`
/// The desired width of the label, in characters.
///
/// If this property is set to -1, the width will be calculated automatically.

/// Readable | Writeable
///
///
/// #### `wrap-mode`
/// Controls how the line wrapping is done.
///
/// This only affects the formatting if line wrapping is on (see the
/// [`wrap`][struct@crate::Label#wrap] property). The default is [enum@Pango.WrapMode.word],
/// which means wrap on word boundaries.
///
/// For sizing behavior, also consider the [`natural-wrap-mode`][struct@crate::Label#natural-wrap-mode]
/// property.
