Implementations

impl<'a> Button<'a>

pub fn new(text: impl Into<WidgetText>) -> Button<'a>

pub fn image(image: impl Into<Image<'a>>) -> Button<'a>

Creates a button with an image. The size of the image as displayed is defined by the provided size.

pub fn image_and_text( image: impl Into<Image<'a>>, text: impl Into<WidgetText> ) -> Button<'a>

Creates a button with an image to the left of the text. The size of the image as displayed is defined by the provided size.

pub fn opt_image_and_text( image: Option<Image<'a>>, text: Option<WidgetText> ) -> Button<'a>

pub fn wrap_mode(self, wrap_mode: TextWrapMode) -> Button<'a>

Set the wrap mode for the text.

By default, crate::Ui::wrap_mode will be used, which can be overridden with crate::Style::wrap_mode.

pub fn wrap(self) -> Button<'a>

pub fn truncate(self) -> Button<'a>

Set Self::wrap_mode to TextWrapMode::Truncate.

pub fn fill(self, fill: impl Into<Color32>) -> Button<'a>

Override background fill color. Note that this will override any on-hover effects. Calling this will also turn on the frame.

pub fn stroke(self, stroke: impl Into<Stroke>) -> Button<'a>

Override button stroke. Note that this will override any on-hover effects. Calling this will also turn on the frame.

pub fn small(self) -> Button<'a>

Make this a small button, suitable for embedding into text.

pub fn frame(self, frame: bool) -> Button<'a>

Turn off the frame

pub fn sense(self, sense: Sense) -> Button<'a>

By default, buttons senses clicks. Change this to a drag-button with Sense::drag().

pub fn min_size(self, min_size: Vec2) -> Button<'a>

Set the minimum size of the button.

pub fn rounding(self, rounding: impl Into<Rounding>) -> Button<'a>

Set the rounding of the button.

pub fn shortcut_text(self, shortcut_text: impl Into<WidgetText>) -> Button<'a>

Show some text on the right side of the button, in weak color.

Designed for menu buttons, for setting a keyboard shortcut text (e.g. Ctrl+S).

The text can be created with crate::Context::format_shortcut.
