Expand description

Trait containing all TextTag methods.

Implementors

TextTag

Required methods

This is supported on crate feature v3_20 only.

Emits the signal::TextTagTable::tag-changed signal on the TextTagTable where the tag is included.

The signal is already emitted when setting a TextTag property. This function is useful for a TextTag subclass.

size_changed

whether the change affects the TextView layout.

Emits the “event” signal on the TextTag.

event_object

object that received the event, such as a widget

event

the event

iter

location where the event was received

Returns

result of signal emission (whether the event was handled)

Get the tag priority.

Returns

The tag’s priority.

Sets the priority of a TextTag. Valid priorities start at 0 and go to one less than TextTagTableExt::size(). Each tag in a table has a unique priority; setting the priority of one tag shifts the priorities of all the other tags in the table to maintain a unique priority for each tag. Higher priority tags “win” if two tags both set the same text attribute. When adding a tag to a tag table, it will be assigned the highest priority in the table by default; so normally the precedence of a set of tags is the order in which they were added to the table, or created with gtk_text_buffer_create_tag(), which adds the tag to the buffer’s table automatically.

priority

the new priority

Whether the margins accumulate or override each other.

When set to true the margins of this tag are added to the margins of any other non-accumulative margins present. When set to false the margins override one another (the default).

Whether the margins accumulate or override each other.

When set to true the margins of this tag are added to the margins of any other non-accumulative margins present. When set to false the margins override one another (the default).

Background color as a gdk::RGBA.

Background color as a gdk::RGBA.

Whether font fallback is enabled.

When set to true, other fonts will be substituted where the current font is missing glyphs.

Whether font fallback is enabled.

When set to true, other fonts will be substituted where the current font is missing glyphs.

Font description as string, e.g. "Sans Italic 12".

Note that the initial value of this property depends on the internals of pango::FontDescription.

Note that the initial value of this property depends on the internals of pango::FontDescription.

OpenType font features, as a string.

OpenType font features, as a string.

Foreground color as a gdk::RGBA.

Foreground color as a gdk::RGBA.

Whether this text is hidden.

Note that there may still be problems with the support for invisible text, in particular when navigating programmatically inside a buffer containing invisible segments.

Whether this text is hidden.

Note that there may still be problems with the support for invisible text, in particular when navigating programmatically inside a buffer containing invisible segments.

The language this text is in, as an ISO code. Pango can use this as a hint when rendering the text. If not set, an appropriate default will be used.

Note that the initial value of this property depends on the current locale, see also default_language().

The paragraph background color as a string.

The paragraph background color as a gdk::RGBA.

This property modifies the color of strikeouts. If not set, strikeouts will use the forground color.

This property modifies the color of strikeouts. If not set, strikeouts will use the forground color.

If the property::TextTag::strikethrough-rgba property has been set.

If the property::TextTag::strikethrough-rgba property has been set.

This property modifies the color of underlines. If not set, underlines will use the forground color.

If property::TextTag::underline is set to pango::Underline::Error, an alternate color may be applied instead of the foreground. Setting this property will always override those defaults.

If property::TextTag::underline is set to pango::Underline::Error, an alternate color may be applied instead of the foreground. Setting this property will always override those defaults.

If the property::TextTag::underline-rgba property has been set.

If the property::TextTag::underline-rgba property has been set.

The ::event signal is emitted when an event occurs on a region of the buffer marked with this tag.

object

the object the event was fired from (typically a TextView)

event

the event which triggered the signal

iter

a TextIter pointing at the location the event occurred

Returns

true to stop other handlers from being invoked for the event. false to propagate the event further.
