Member Function Documentation
double Gtk::Label::get_angle | ( | ) | const |
Gets the angle of rotation for the label.
See set_angle().
{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
0
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.
{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().
@newin{2,6} @return Pango::EllipsizeMode.
Justification Gtk::Label::get_justify | ( | ) | const |
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:
-
x Location to store X offset of layout, or 0
.y Location to store Y offset of layout, or 0
.
bool Gtk::Label::get_line_wrap | ( | ) | const |

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_offset Start offset (in characters not bytes). end_offset End 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_offset Start 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.
{2,6}
- Parameters:
-
angle The 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:
-
attrs A 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.
{2,6}
- Parameters:
-
mode A 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:
-
jtype A 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:
-
str The 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:
-
wrap The 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.
{2,10}
- Parameters:
-
wrap_mode The 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:
-
str A 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:
-
str A 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.
{2,6}
- Parameters:
-
n_chars The 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:
-
widget The target Gtk::Widget.
void Gtk::Label::set_pattern | ( | const Glib::ustring & | pattern | ) |
The pattern of underlines you want under the existing text within the Gtk::Label widget.
For example if the current text of the label says "FooBarBaz" passing a pattern of "___ ___" will underline "Foo" and "Baz" but not "Bar".
- Parameters:
-
pattern The pattern as described above.
void Gtk::Label::set_selectable | ( | bool | setting = true | ) |
Selectable labels allow the user to select text from the label, for copy-and-paste.
- Parameters:
-
setting true
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.
{2,6}
- Parameters:
-
single_line_mode true
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:
-
str A 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).
{2,18}
- Parameters:
-
track_links true
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:
-
setting true
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:
-
setting true
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.
{2,6}
- Parameters:
-
n_chars The new desired width, in characters.
Glib::SignalProxy1< bool,const Glib::ustring& > Gtk::Label::signal_activate_link | ( | ) |
- Slot Prototype:
bool on_my_activate_link(const Glib::ustring& uri)
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().
{2,18}
- Parameters:
-
uri The URI that is activated.
- Returns:
true
if the link has been activated.
Glib::SignalProxy1< void,Menu* > Gtk::Label::signal_populate_popup | ( | ) |
- Slot Prototype:
void on_my_populate_popup(Menu* menu)
The signal_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:
-
menu The menu that is being populated.
