Detailed Description

A widget that displays a small to medium amount of text.

A simple setable widget for holding a Glib::ustring.

The Label widget looks like this:

label1.png

Constructor & Destructor Documentation

virtual Gtk::Label::~Label ( )
virtual
Gtk::Label::Label ( )
Gtk::Label::Label ( const Glib::ustring label,
bool  mnemonic = false 
)
explicit
Gtk::Label::Label ( const Glib::ustring label,
float  xalign,
float  yalign,
bool  mnemonic = false 
)

This constructor is a shortcut for often used code when you want to create a label with alignment different than default one.

Gtk::Label label(text, x, y, mnemonic);

is equivalent to:

Gtk::Label label(text, mnemonic);
label.set_alignment(x, y);
Gtk::Label::Label ( const Glib::ustring label,
AlignmentEnum  xalign,
AlignmentEnum  yalign = ALIGN_CENTER,
bool  mnemonic = false 
)

This constructor is a shortcut for often used code when you want to create a label with alignment different than default one.

Gtk::Label label(text, x, y, mnemonic);

is equivalent to:

Gtk::Label label(text, mnemonic);
label.set_alignment(x, y);

Member Function Documentation

double Gtk::Label::get_angle ( ) const

Gets the angle of rotation for the label.

See set_angle().

Since gtkmm 2.6:
Returns
The angle of rotation for the label.
Pango::AttrList Gtk::Label::get_attributes ( ) const

Gets the attribute list that was set on the label using set_attributes(), if any.

This function does not reflect attributes that come from the labels markup (see set_markup()). If you want to get the effective attributes for the label, use pango_layout_get_attribute (gtk_label_get_layout (label)).

Returns
The attribute list, or nullptr if none was set.
Glib::ustring Gtk::Label::get_current_uri ( ) const

Returns the URI for the currently active link in the label.

The active link is the one under the mouse pointer or, in a selectable label, the link in which the text cursor is currently positioned.

This function is intended for use in a Gtk::Label::signal_activate_link() handler or for use in a Gtk::Widget::signal_query_tooltip() handler.

Since gtkmm 2.18:
Returns
The currently active URI. The string is owned by GTK+ and must not be freed or modified.
Pango::EllipsizeMode Gtk::Label::get_ellipsize ( ) const

Returns the ellipsizing position of the label.

See set_ellipsize().

Since gtkmm 2.6:
Returns
Pango::EllipsizeMode.
Justification Gtk::Label::get_justify ( ) const

Returns the justification of the label.

See set_justify().

Returns
Gtk::Justification.
Glib::ustring Gtk::Label::get_label ( ) const

Fetches the text from a label widget including any embedded underlines indicating mnemonics and Pango markup.

(See get_text()).

Returns
The text of the label widget..
Glib::RefPtr<Pango::Layout> Gtk::Label::get_layout ( )

Gets the Pango::Layout used to display the label.

The layout is useful to e.g. convert text positions to pixel positions, in combination with get_layout_offsets().

Returns
The Pango::Layout for this label.
Glib::RefPtr<const Pango::Layout> Gtk::Label::get_layout ( ) const

Gets the Pango::Layout used to display the label.

The layout is useful to e.g. convert text positions to pixel positions, in combination with get_layout_offsets().

Returns
The Pango::Layout for this label.
void Gtk::Label::get_layout_offsets ( int &  x,
int &  y 
) const

Obtains the coordinates where the label will draw the Pango::Layout representing the text in the label; useful to convert mouse events into coordinates inside the Pango::Layout, e.g. to take some action if some part of the label is clicked.

Of course you will need to create a Gtk::EventBox to receive the events, and pack the label inside it, since labels are a Gtk::NO_WINDOW widget. Remember when using the Pango::Layout functions you need to convert to and from pixels using PANGO_PIXELS() or Pango::SCALE.

Parameters
xLocation to store X offset of layout, or nullptr.
yLocation to store Y offset of layout, or nullptr.
bool Gtk::Label::get_line_wrap ( ) const

Returns whether lines in the label are automatically wrapped.

See set_line_wrap().

Returns
true if the lines of the label are automatically wrapped.
Pango::WrapMode Gtk::Label::get_line_wrap_mode ( ) const

Returns line wrap mode used by the label.

See set_line_wrap_mode().

Since gtkmm 2.10:
Returns
true if the lines of the label are automatically wrapped.
int Gtk::Label::get_max_width_chars ( ) const

Retrieves the desired maximum width of label, in characters.

See set_width_chars().

Since gtkmm 2.6:
Returns
The maximum width of the label in characters.
guint Gtk::Label::get_mnemonic_keyval ( ) const

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.

Returns
GDK keyval usable for accelerators, or #GDK_VoidSymbol.
Widget* Gtk::Label::get_mnemonic_widget ( )

Retrieves the target of the mnemonic (keyboard shortcut) of this label.

See set_mnemonic_widget().

Returns
The target of the label's mnemonic, or nullptr if none has been set and the default algorithm will be used.
const Widget* Gtk::Label::get_mnemonic_widget ( ) const

Retrieves the target of the mnemonic (keyboard shortcut) of this label.

See set_mnemonic_widget().

Returns
The target of the label's mnemonic, or nullptr if none has been set and the default algorithm will be used.
bool Gtk::Label::get_selectable ( ) const

Gets the value set by set_selectable().

Returns
true if the user can copy text from the label.
bool Gtk::Label::get_selection_bounds ( int &  start,
int &  end 
) const

Gets the selected range of characters in the label, returning true if there's a selection.

Parameters

bool Gtk::Label::get_use_markup ( ) const

Returns whether the label's text is interpreted as marked up with the Pango text markup language.

See set_use_markup().

Returns
true if the label's text will be parsed for markup.
bool Gtk::Label::get_use_underline ( ) const

Returns whether an embedded underline in the label indicates a mnemonic.

See set_use_underline().

Returns
true whether an embedded underline in the label indicates the mnemonic accelerator keys.

void Gtk::Label::select_region ( int  start_offset,
int  end_offset 
)

Selects a range of characters in the label, if the label is selectable.

See 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
start_offsetStart offset (in characters not bytes).
end_offsetEnd offset (in characters not bytes).
void Gtk::Label::select_region ( int  start_offset)

Selects a range of characters in the label, from start_offset to the end, if the label is selectable.

See gtk_label_set_selectable(). If the label is not selectable, this function has no effect.

Parameters
start_offsetStart offset (in characters not bytes)
void Gtk::Label::set_angle ( double  angle)

Sets the angle of rotation for the label.

An angle of 90 reads from from bottom to top, an angle of 270, from top to bottom. The angle setting for the label is ignored if the label is selectable, wrapped, or ellipsized.

Since gtkmm 2.6:
Parameters
angleThe angle that the baseline of the label makes with the horizontal, in degrees, measured counterclockwise.
void Gtk::Label::set_attributes ( Pango::AttrList attrs)

Sets a Pango::AttrList; the attributes in the list are applied to the label text.

<note>The attributes set with this function will be applied and merged with any other attributes previously effected by way of the Gtk::Label::property_use_underline() or Gtk::Label::property_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.</note>

Parameters
attrsA Pango::AttrList.
void Gtk::Label::set_ellipsize ( Pango::EllipsizeMode  mode)

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

Since gtkmm 2.6:
Parameters
modeA Pango::EllipsizeMode.
void Gtk::Label::set_justify ( Justification  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 new(). If you instead want to set the alignment of the label as a whole, use Gtk::Misc::set_alignment() instead. set_justify() has no effect on labels containing only a single line.

Parameters
jtypeA Gtk::Justification.
void Gtk::Label::set_label ( const Glib::ustring str)

Sets the text of the label.

The label is interpreted as including embedded underlines and/or Pango markup depending on the values of the Gtk::Label::property_use_underline()" and Gtk::Label::property_use_markup() properties.

Parameters
strThe new text to set for the label.
void Gtk::Label::set_line_wrap ( bool  wrap = true)

Toggles line wrapping within the Gtk::Label 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
wrapThe setting.
void Gtk::Label::set_line_wrap_mode ( Pango::WrapMode  wrap_mode)

If line wrapping is on (see set_line_wrap()) this controls how the line wrapping is done.

The default is Pango::WRAP_WORD which means wrap on word boundaries.

Since gtkmm 2.10:
Parameters
wrap_modeThe line wrapping mode.
void Gtk::Label::set_markup ( const Glib::ustring 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 Glib::markup_escape_text() or Glib::markup_printf_escaped():

[C example ellipted]

Parameters
strA markup string (see Pango markup format).
void Gtk::Label::set_markup_with_mnemonic ( const Glib::ustring 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 set_mnemonic_widget().

Parameters
strA markup string (see Pango markup format).
void Gtk::Label::set_max_width_chars ( int  n_chars)

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

Since gtkmm 2.6:
Parameters
n_charsThe new desired maximum width, in characters.
void Gtk::Label::set_mnemonic_widget ( Widget widget)

If the label has been set so that it has an mnemonic key (using i.e. set_markup_with_mnemonic(), set_text_with_mnemonic(), 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 Gtk::Button or a Gtk::Notebook tab) it is automatically associated with the correct widget, but sometimes (i.e. when the target is a Gtk::Entry 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
widgetThe target Gtk::Widget.
void Gtk::Label::set_pattern ( const Glib::ustring pattern)
void Gtk::Label::set_selectable ( bool  setting = true)

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

Parameters
settingtrue to allow selecting text in the label.
void Gtk::Label::set_single_line_mode ( bool  single_line_mode = true)

Sets whether the label is in single line mode.

Since gtkmm 2.6:
Parameters
single_line_modetrue if the label should be in single line mode.
void Gtk::Label::set_text ( const Glib::ustring str)

Doesn't use markup.

void Gtk::Label::set_text_with_mnemonic ( const Glib::ustring 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 set_mnemonic_widget().

Parameters
strA string.
void Gtk::Label::set_track_visited_links ( bool  track_links = true)

Sets whether the label should keep track of clicked links (and use a different color for them).

Since gtkmm 2.18:
Parameters
track_linkstrue to track visited links.
void Gtk::Label::set_use_markup ( bool  setting = true)

Sets whether the text of the label contains markup in Pango's text markup language.

See set_markup().

Parameters
settingtrue if the label's text should be parsed for markup.
void Gtk::Label::set_use_underline ( bool  setting = true)

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

Parameters
settingtrue if underlines in the text indicate mnemonics.
void Gtk::Label::set_width_chars ( int  n_chars)

Sets the desired width in characters of label to n_chars.

Since gtkmm 2.6:
Parameters
n_charsThe new desired width, in characters.
