[−][src]Struct fui::cursive::views::Button
Simple text label with a callback when
A button shows its content in a single line and has a fixed size.
Examples
let quit_button = Button::new("Quit", |s| s.quit());
Methods
impl Button
[src]
pub fn new<F, S>(label: S, cb: F) -> Button where
F: 'static + Fn(&mut Cursive),
S: Into<String>,
[src]
F: 'static + Fn(&mut Cursive),
S: Into<String>,
Creates a new button with the given content and callback.
pub fn new_raw<F, S>(label: S, cb: F) -> Button where
F: 'static + Fn(&mut Cursive),
S: Into<String>,
[src]
F: 'static + Fn(&mut Cursive),
S: Into<String>,
Creates a new button without angle brackets.
pub fn set_callback<F>(&mut self, cb: F) where
F: Fn(&mut Cursive) + 'static,
[src]
F: Fn(&mut Cursive) + 'static,
Sets the function to be called when the button is pressed.
Replaces the previous callback.
pub fn disable(&mut self)
[src]
Disables this view.
A disabled view cannot be selected.
pub fn disabled(self) -> Button
[src]
Disables this view.
Chainable variant.
pub fn enable(&mut self)
[src]
Re-enables this view.
pub fn set_enabled(&mut self, enabled: bool)
[src]
Enable or disable this view.
pub fn is_enabled(&self) -> bool
[src]
Returns true
if this view is enabled.
pub fn label(&self) -> &str
[src]
Returns the label for this button.
Includes brackets.
Examples
let button = Button::new("Quit", |s| s.quit()); assert_eq!(button.label(), "<Quit>");
pub fn set_label<S>(&mut self, label: S) where
S: Into<String>,
[src]
S: Into<String>,
Sets the label to the given value.
This will include brackets.
pub fn set_label_raw<S>(&mut self, label: S) where
S: Into<String>,
[src]
S: Into<String>,
Sets the label exactly to the given value.
This will not include brackets.
