§`font_desc`

a pango::FontDescription

Source

fn set_font_name(&self, font_name: Option<&str>)

Sets the font used by a Text. The font_name string must either be None, which means that the font name from the default Backend will be used; or be something that can be parsed by the pango::FontDescription::from_string function, like:

  // Set the font to the system's Sans, 10 points
  text_set_font_name (text, "Sans 10");

  // Set the font to the system's Serif, 16 pixels
  text_set_font_name (text, "Serif 16px");

  // Set the font to Helvetica, 10 points
  text_set_font_name (text, "Helvetica 10");

§`font_name`

a font name, or None to set the default font name

Source

fn set_justify(&self, justify: bool)

§`justify`

whether the text should be justified

Source

fn set_line_alignment(&self, alignment: Alignment)

Sets the way that the lines of a wrapped label are aligned with respect to each other. This does not affect the overall alignment of the label within its allocated or specified width.

§`wrap_mode`

the line wrapping mode

Source

fn set_markup(&self, markup: Option<&str>)

Sets markup as the contents of a Text.

This is a convenience function for setting a string containing Pango markup, and it is logically equivalent to:

  /&ast; the order is important &ast;/
  text_set_text (TEXT (actor), markup);
  text_set_use_markup (TEXT (actor), true);

§`markup`

a string containing Pango markup. Passing None is the same as passing “” (the empty string)

Source

fn set_preedit_string( &self, preedit_str: Option<&str>, preedit_attrs: Option<&AttrList>, cursor_pos: u32, )

Sets, or unsets, the pre-edit string. This function is useful for input methods to display a string (with eventual specific Pango attributes) before it is entered inside the Text buffer.

The preedit string and attributes are ignored if the Text actor is not editable.

This function should not be used by applications

§`preedit_str`

the pre-edit string, or None to unset it

§`preedit_attrs`

the pre-edit string attributes

§`cursor_pos`

the cursor position for the pre-edit string

§`selectable`

whether the Text actor should be selectable

Source

fn set_selected_text_color(&self, color: Option<&InternalColor>)

Sets the selected text color of a Text actor.

If color is None, the selected text color will be the same as the selection color, which then falls back to cursor, and then text color.

§`color`

the selected text color, or None to unset it

Source

fn set_selection(&self, start_pos: isize, end_pos: isize)

Selects the region of text between start_pos and end_pos.

This function changes the position of the cursor to match start_pos and the selection bound to match end_pos.

§`start_pos`

start of the selection, in characters

§`end_pos`

end of the selection, in characters

Source

fn set_selection_bound(&self, selection_bound: i32)

the position of the end of the selection, in characters

Source

fn set_selection_color(&self, color: Option<&InternalColor>)

Sets the color of the selection of a Text actor.

If color is None, the selection color will be the same as the cursor color, or if no cursor color is set either then it will be the same as the text color.

§`color`

the color of the selection, or None to unset it

Source

fn set_single_line_mode(&self, single_line: bool)

Sets whether a Text actor should be in single line mode or not. Only editable Texts can be in single line mode.

A text actor in single line mode will not wrap text and will clip the visible area to the predefined size. The contents of the text actor will scroll to display the end of the text if its length is bigger than the allocated width.

When setting the single line mode the Text:activatable property is also set as a side effect. Instead of entering a new line character, the text actor will emit the Text::activate signal.

§`single_line`

whether to enable single line mode

Source

fn set_text(&self, text: Option<&str>)

Sets the contents of a Text actor.

If the Text:use-markup property was set to true it will be reset to false as a side effect. If you want to maintain the Text:use-markup you should use the TextExt::set_markup function instead

§`text`

the text to set. Passing None is the same as passing “” (the empty string)

Source

fn set_use_markup(&self, setting: bool)

Sets whether the contents of the Text actor contains markup in Pango’s text markup language</link>.

Setting Text:use-markup on an editable Text will not have any effect except hiding the markup.

§`setting`

true if the text should be parsed for markup.

Source

fn get_property_cursor_color_set(&self) -> bool

Will be set to true if Text:cursor-color has been set.

Source

fn get_property_selected_text_color_set(&self) -> bool

Will be set to true if Text:selected-text-color has been set.

Source

fn get_property_selection_color_set(&self) -> bool

Will be set to true if Text:selection-color has been set.

Source

fn connect_activate<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId

The ::activate signal is emitted each time the actor is ‘activated’ by the user, normally by pressing the ‘Enter’ key. The signal is emitted only if Text:activatable is set to true.

Source

fn connect_cursor_changed<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId

The ::cursor-changed signal is emitted whenever the cursor position or size changes.

Source

fn connect_delete_text<F: Fn(&Self, i32, i32) + 'static>( &self, f: F, ) -> SignalHandlerId

This signal is emitted when text is deleted from the actor by the user. It is emitted before self_ text changes.

§`start_pos`

the starting position

§`end_pos`

the end position

Source

fn emit_delete_text(&self, start_pos: i32, end_pos: i32)

Source

fn connect_text_changed<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId

The ::text-changed signal is emitted after actor’s text changes

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
