Struct conrod::widget::text_edit::TextEdit

pub struct TextEdit<'a> { /* fields omitted */ }

A widget for displaying and mutating multi-line text, given as a String.

By default the text is wrapped via the first whitespace before the line exceeds the TextEdit's width, however a user may change this using the .wrap_by_character method.

Methods

impl<'a> TextEdit<'a>

fn new(text: &'a str) -> Self

Construct a TextEdit widget.

fn wrap_by_whitespace(self) -> Self

The TextEdit will wrap text via the whitespace that precedes the first width-exceeding character.

This is the default setting.

fn wrap_by_character(self) -> Self

By default, the TextEdit will wrap text via the whitespace that precedes the first width-exceeding character.

Calling this method causes the TextEdit to wrap text at the first exceeding character.

fn left_justify(self) -> Self

Align the text to the left of its bounding Rect's x axis range.

fn center_justify(self) -> Self

Align the text to the middle of its bounding Rect's x axis range.

fn right_justify(self) -> Self

Align the text to the right of its bounding Rect's x axis range.

fn align_text_bottom(self) -> Self

Align the text to the left of its bounding Rect's y axis range.

fn align_text_y_middle(self) -> Self

Align the text to the middle of its bounding Rect's y axis range.

fn align_text_top(self) -> Self

Align the text to the right of its bounding Rect's y axis range.

fn align_text_middle(self) -> Self

Align the text to the middle of its bounding Rect.

fn font_id(self, font_id: Id) -> Self

Specify the font used for displaying the text.

fn font_size(self, font_size: FontSize) -> Self

Build the type's self.$($assignee).+ with the given $Type.

fn justify(self, justify: Justify) -> Self

Build the type's self.$($assignee).+ with the given $Type.

fn y_align_text(self, y_align_text: Align) -> Self

Build the type's self.$($assignee).+ with the given $Type.

fn line_wrap(self, line_wrap: Wrap) -> Self

Build the type's self.$($assignee).+ with the given $Type.

fn line_spacing(self, line_spacing: Scalar) -> Self

Build the type's self.$($assignee).+ with the given $Type.

fn restrict_to_height(self, restrict_to_height: bool) -> Self

Build the type's self.$($assignee).+ with the given $Type.

Trait Implementations

impl<'a> Widget for TextEdit<'a>

type State = State

State to be stored within the Uis widget cache.

type Style = Style

Every widget is required to have its own associated Style type. This type is intended to contain high-level styling information for the widget that can be optionally specified by a user of the widget.

type Event = Option<String>

The type of event yielded by the widget, returned via the Widget::set function.

fn init_state(&self, id_gen: Generator) -> Self::State

Return the initial State of the Widget.

fn style(&self) -> Self::Style

Return the styling of the widget.

fn default_y_dimension(&self, ui: &Ui) -> Dimension

The default height of the widget.

fn update(self, args: UpdateArgs<Self>) -> Self::Event

Update the state of the TextEdit.

fn default_x_position(&self, ui: &Ui) -> Position

The default Position for the widget along the x axis.

fn default_y_position(&self, ui: &Ui) -> Position

The default Position for the widget along the y axis.

fn default_x_dimension(&self, ui: &Ui) -> Dimension

The default width for the Widget.

fn drag_area(
    &self,
    _dim: Dimensions,
    _style: &Self::Style,
    _theme: &Theme
) -> Option<Rect>

If the widget is draggable, implement this method and return the position and dimensions of the draggable space. The position should be relative to the center of the widget.

fn kid_area(&self, args: KidAreaArgs<Self>) -> KidArea

The area on which child widgets will be placed when using the Place Position methods.

fn is_over(&self) -> IsOverFn

Returns either of the following:

fn parent(self, parent_id: Id) -> Self

Set the parent widget for this Widget by passing the WidgetId of the parent.

fn no_parent(self) -> Self

Specify that this widget has no parent widgets.

fn place_on_kid_area(self, b: bool) -> Self

Set whether or not the Widget should be placed on the kid_area.

fn graphics_for(self, id: Id) -> Self

Indicates that the Widget is used as a non-interactive graphical element for some other widget.

fn floating(self, is_floating: bool) -> Self

Set whether or not the widget is floating (the default is false). A typical example of a floating widget would be a pop-up or alert window.

fn crop_kids(self) -> Self

Indicates that all widgets who are children of this widget should be cropped to the kid_area of this widget.

fn scroll_kids(self) -> Self

Makes the widget's KidArea scrollable.

fn scroll_kids_vertically(self) -> Self

Makes the widget's KidArea scrollable.

fn scroll_kids_horizontally(self) -> Self

Set whether or not the widget's KidArea is scrollable (the default is false).

fn and<F>(self, build: F) -> Self where
    F: FnOnce(Self) -> Self, 

A builder method that "lifts" the Widget through the given build function.

fn and_mut<F>(self, mutate: F) -> Self where
    F: FnOnce(&mut Self), 

A builder method that mutates the Widget with the given mutate function.

fn and_if<F>(self, cond: bool, build: F) -> Self where
    F: FnOnce(Self) -> Self, 

A method that conditionally builds the Widget with the given build function.

fn and_then<T, F>(self, maybe: Option<T>, build: F) -> Self where
    F: FnOnce(Self, T) -> Self, 

A method that optionally builds the Widget with the given build function.

fn set<'a, 'b>(self, id: Id, ui_cell: &'a mut UiCell<'b>) -> Self::Event

Note: There should be no need to override this method.
