Implementations

impl TextBuilder

pub fn activates_default(self, activates_default: bool) -> Self

Whether to activate the default widget when Enter is pressed.

pub fn attributes(self, attributes: &AttrList) -> Self

A list of Pango attributes to apply to the text of the Text.

This is mainly useful to change the size or weight of the text.

The PangoAttribute’s start_index and end_index must refer to the EntryBuffer text, i.e. without the preedit string.

pub fn buffer<P: IsA<EntryBuffer>>(self, buffer: &P) -> Self

The EntryBuffer object which stores the text.

pub fn enable_emoji_completion(self, enable_emoji_completion: bool) -> Self

Whether to suggest Emoji replacements.

A menu model whose contents will be appended to the context menu.

pub fn im_module(self, im_module: &str) -> Self

Which IM (input method) module should be used for this self.

See IMMulticontext.

Setting this to a non-None value overrides the system-wide IM module setting. See the property::Settings::gtk-im-module property.

pub fn input_hints(self, input_hints: InputHints) -> Self

Additional hints that allow input methods to fine-tune their behaviour.

pub fn input_purpose(self, input_purpose: InputPurpose) -> Self

The purpose of this text field.

This property can be used by on-screen keyboards and other input methods to adjust their behaviour.

Note that setting the purpose to InputPurpose::Password or InputPurpose::Pin is independent from setting property::Text::visibility.

pub fn invisible_char(self, invisible_char: u32) -> Self

The character to used when masking contents (in “password mode”).

pub fn invisible_char_set(self, invisible_char_set: bool) -> Self

Whether the invisible char has been set for the Text.

pub fn max_length(self, max_length: i32) -> Self

Maximum number of characters that are allowed.

Zero indicates no limit.

pub fn overwrite_mode(self, overwrite_mode: bool) -> Self

If text is overwritten when typing in the Text.

pub fn placeholder_text(self, placeholder_text: &str) -> Self

pub fn propagate_text_width(self, propagate_text_width: bool) -> Self

Whether the widget should grow and shrink with the content.

pub fn tabs(self, tabs: &TabArray) -> Self

A list of tabstops to apply to the text of the Text.

pub fn truncate_multiline(self, truncate_multiline: bool) -> Self

When true, pasted multi-line text is truncated to the first line.

pub fn visibility(self, visibility: bool) -> Self

If false, the text is masked with the “invisible char”.

pub fn can_focus(self, can_focus: bool) -> Self

Whether the widget or any of its descendents can accept the input focus.

This property is meant to be set by widget implementations, typically in their instance init function.

pub fn can_target(self, can_target: bool) -> Self

Whether the widget can receive pointer events.

pub fn css_classes(self, css_classes: Vec<String>) -> Self

A list of css classes applied to this widget.

pub fn css_name(self, css_name: &str) -> Self

pub fn cursor(self, cursor: &Cursor) -> Self

The cursor used by widget.

pub fn focus_on_click(self, focus_on_click: bool) -> Self

Whether the widget should grab focus when it is clicked with the mouse.

This property is only relevant for widgets that can take focus.

pub fn focusable(self, focusable: bool) -> Self

Whether this widget itself will accept the input focus.

pub fn halign(self, halign: Align) -> Self

How to distribute horizontal space if widget gets extra space.

pub fn has_tooltip(self, has_tooltip: bool) -> Self

Enables or disables the emission of the ::query-tooltip signal on widget.

A value of true indicates that widget can have a tooltip, in this case the widget will be queried using signal::Widget::query-tooltip to determine whether it will provide a tooltip or not.

pub fn height_request(self, height_request: i32) -> Self

Override for height request of the widget.

If this is -1, the natural request will be used.

pub fn hexpand(self, hexpand: bool) -> Self

Whether to expand horizontally.

pub fn hexpand_set(self, hexpand_set: bool) -> Self

Whether to use the hexpand property.

pub fn layout_manager<P: IsA<LayoutManager>>(self, layout_manager: &P) -> Self

This property is meant to be set by widget implementations, typically in their instance init function.

pub fn margin_bottom(self, margin_bottom: i32) -> Self

Margin on bottom side of widget.

This property adds margin outside of the widget’s normal size request, the margin will be added in addition to the size from WidgetExt::set_size_request() for example.

pub fn margin_end(self, margin_end: i32) -> Self

Margin on end of widget, horizontally.

This property supports left-to-right and right-to-left text directions.

pub fn margin_start(self, margin_start: i32) -> Self

Margin on start of widget, horizontally.

This property supports left-to-right and right-to-left text directions.

pub fn margin_top(self, margin_top: i32) -> Self

Margin on top side of widget.

This property adds margin outside of the widget’s normal size request, the margin will be added in addition to the size from WidgetExt::set_size_request() for example.

pub fn name(self, name: &str) -> Self
