Detailed Description

Gtk::Inscription is a widget to show text in a predefined area.

You likely want to use Gtk::Label instead as this widget is intended only for a small subset of use cases. The main scenario envisaged is inside lists such as Gtk::ColumnView.

While a Gtk::Label sizes itself depending on the text that is displayed, Gtk::Inscription is given a size and inscribes the given text into that space as well as it can.

Users of this widget should take care to plan behaviour for the common case where the text doesn't fit exactly in the allocated space.

Since gtkmm 4.8:

Glib::PropertyProxy_WriteOnly< Glib::ustring > Gtk::Inscription::property_markup ( )

Utility property that sets both the property_text() and property_attributes() properties, mainly intended for use in GtkBuilder ui files to ease translation support and bindings.

This function uses pango_parse_markup() to parse the markup into text and attributes. The markup must be valid. If you cannot ensure that, consider using pango_parse_markup() and setting the two properties yourself.

◆ property_min_chars() [1/2]

Glib::PropertyProxy< unsigned int > Gtk::Inscription::property_min_chars ( )

The number of characters that should fit into the inscription at minimum.

This influences the requested width, not the width actually given to the widget, which might turn out to be larger.

Note that this is an approximate character width, so some characters might be wider and some might be thinner, so do not expect the number of characters to exactly match.

If you set this property to 0, the inscription will not request any width at all and its width will be determined entirely by its surroundings.

Since gtkmm 4.8:

Default value: 3

Returns: A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

◆ property_min_chars() [2/2]

Glib::PropertyProxy_ReadOnly< unsigned int > Gtk::Inscription::property_min_chars ( ) const

The number of characters that should fit into the inscription at minimum.

This influences the requested width, not the width actually given to the widget, which might turn out to be larger.

Note that this is an approximate character width, so some characters might be wider and some might be thinner, so do not expect the number of characters to exactly match.

If you set this property to 0, the inscription will not request any width at all and its width will be determined entirely by its surroundings.

Since gtkmm 4.8:

Default value: 3

Returns: A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

◆ property_min_lines() [1/2]

Glib::PropertyProxy< unsigned int > Gtk::Inscription::property_min_lines ( )

The number of lines that should fit into the inscription at minimum.

This influences the requested height, not the height actually given to the widget, which might turn out to be larger.

Note that this is an approximate line height, so if the text uses things like fancy Unicode or attribute that influence the height, the text might not fit.

If you set this property to 0, the inscription will not request any height at all and its height will be determined entirely by its surroundings.

Since gtkmm 4.8:

Default value: 1

Returns: A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

◆ property_min_lines() [2/2]

Glib::PropertyProxy_ReadOnly< unsigned int > Gtk::Inscription::property_min_lines ( ) const

The number of lines that should fit into the inscription at minimum.

This influences the requested height, not the height actually given to the widget, which might turn out to be larger.

Note that this is an approximate line height, so if the text uses things like fancy Unicode or attribute that influence the height, the text might not fit.

If you set this property to 0, the inscription will not request any height at all and its height will be determined entirely by its surroundings.

Since gtkmm 4.8:

Default value: 1

Returns: A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

◆ property_nat_chars() [1/2]

Glib::PropertyProxy< unsigned int > Gtk::Inscription::property_nat_chars ( )

The number of characters that should ideally fit into the inscription.

This influences the requested width, not the width actually given to the widget. The widget might turn out larger as well as smaller.

If this property is set to a value smaller than property_min_chars(), that value will be used. In particular, for the default value of 0, this will always be the case.

Since gtkmm 4.8:

Default value: 0

Returns: A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

◆ property_nat_chars() [2/2]

Glib::PropertyProxy_ReadOnly< unsigned int > Gtk::Inscription::property_nat_chars ( ) const

The number of characters that should ideally fit into the inscription.

This influences the requested width, not the width actually given to the widget. The widget might turn out larger as well as smaller.

Since gtkmm 4.8:

Default value: 0

Returns: A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.
