Struct rstk::label::TkLabel

pub struct TkLabel {
    pub id: String,
}

Refers to a label widget

Fields

id: String

Implementations

impl TkLabel

pub fn anchor(&self, value: Anchor)

Position of information with respect to internal margins.

e.g. the space allocated to the label can be larger than its text needs, so an Anchor value of E (east) will display the text against the right-margin.

pub fn background(&self, colour: &str)

Specifies the background colour.

Colours are specified as a string, by either:

• name - using one of the values in the tk colours list
• rgb - as a 6-digit hexadecimal value in form “#RRGGBB”

pub fn justify(&self, value: Justify)

Alignment of text within widget.

pub fn relief(&self, value: Relief)

Style of border around label.

pub fn wrap_length(&self, length: u64)

Sets the maximum line length, in pixels. When set, displayed text is separated into lines, not exceeding the given length.

Trait Implementations

impl Clone for TkLabel

fn clone(&self) -> TkLabel

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TkLabel

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TkLabel

fn eq(&self, other: &TkLabel) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TkGridLayout for TkLabel

fn grid(&self) -> GridLayout

Creates a GridLayout instance for placing this widget within its parent.

fn grid_configure(&self, option: &str, value: &str)

Sets properties for widget layout directly through Tk: see Tk manual for options.

fn grid_forget(&self)

Removes this widget from layout.

impl TkLabelOptions for TkLabel

fn compound(&self, value: Compound)

Sets how to arrange the image relative to the text.

fn font(&self, definition: &TkFont)

Sets the font to use for text.

fn foreground(&self, colour: &str)

Sets the foreground (text) colour.

fn image(&self, image: &TkImage)

Sets an image to display on the widget.

fn padding(&self, values: &[u64])

Sets space around the widget. Takes an array of up to four values, specifying the number of pixels on the different sides:

fn text(&self, value: &str)

Sets the text label for the widget.

fn underline(&self, index: u64)

Underlines the character at the given index position.

fn width(&self, value: i64)

Sets the width of the widget, in characters

impl TkPackLayout for TkLabel

fn pack(&self) -> PackLayout

Creates a PackLayout instance for placing this widget within its parent

fn pack_configure(&self, option: &str, value: &str)

Sets properties for widget layout

fn pack_forget(&self)

Removes this widget from layout

impl TkWidget for TkLabel

fn id(&self) -> &str

Returns the widget’s id reference - used within tk

fn bind(&self, pattern: &str, command: impl Fn(TkEvent) + Send + 'static)

fn cget(&self, option: &str) -> String

Retrieve the value of a configuration option as a string.

fn configure(&self, option: &str, value: &str)

Used to change properties of a widget. This function can be used to directly configure the widget using an option-value string pair:

fn destroy(&self)

Destroys a widget and its children.

fn winfo(&self, option: &str) -> String

winfo retrieves information about widget.

fn focus(&self)

Makes this widget the focus window (e.g. for key presses)

fn position_x(&self) -> u64

Returns the widget x position in pixels, within its parent.

fn position_y(&self) -> u64

Returns the widget y position in pixels, within its parent.

fn widget_height(&self) -> u64

Returns the widget height in pixels.

fn widget_width(&self) -> u64

Returns the widget width in pixels.

fn mouse_position(&self) -> (i64, i64)

fn screen_width_mm(&self) -> u64

Width of screen of widget in millimetres.

fn lower(&self)

Lowers the widget in stacking order.

fn raise(&self)

Raises the widget in stacking order.

fn grid_configure_column(&self, index: u64, option: &str, value: &str)

Sets property for a given column of the grid layout contained within this widget.

fn grid_configure_row(&self, index: u64, option: &str, value: &str)

Sets property for a given row of the grid layout contained within this widget.
