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.

| 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.
| start_offset | Start offset (in characters not bytes) |
| 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.
| start_offset | Start offset (in characters not bytes). | |
| end_offset | End 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.
| 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.
The attributes set with this function will be ignored if the "use_underline" property or the "use_markup" property is true.
| 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.
| 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.
| 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 label->use_underline and label->use_markup.
| 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.
| wrap | The setting. |
| void Gtk::Label::set_line_wrap_mode | ( | Pango::WrapMode | wrap_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()<!-- -->:
char *markup; <!-- --> markup = g_markup_printf_escaped ("<span style=\"italic\">%s</span>", str); gtk_label_set_markup (GTK_LABEL (label), markup); g_free (markup);
| 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().
| 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 .
| 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 "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.
| widget | The 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.
| 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.
| single_line_mode | true if the label should be in single line mode. |
| void Gtk::Label::set_text | ( | const Glib::ustring & | str | ) |
Sets the text within the Gtk::Label widget.
It overwrites any text that was there before.
This will also clear any previously set mnemonic accelerators.
| str | The text you want to set. |
| 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().
| str | A string. |
| 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().
| 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.
| 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 .
| n_chars | The new desired width, in characters. |
| Glib::SignalProxy1<void,Menu*> Gtk::Label::signal_populate_popup | ( | ) |
void on_my_populate_popup(Menu* menu)
| Gtk::Label* wrap | ( | GtkLabel * | object, | |
| bool | take_copy = false | |||
| ) | [related] |
A Glib::wrap() method for this object.
| object | The C instance. | |
| take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref. |
