Struct cursive::views::EditView
[−]
[src]
pub struct EditView { /* fields omitted */ }
Input box where the user can enter and edit text.
Examples
From the edit example.
let mut siv = Cursive::new(); // Create a dialog with an edit text and a button. // The user can either hit the <Ok> button, // or press Enter on the edit text. siv.add_layer( Dialog::new() .title("Enter your name") .padding((1, 1, 1, 0)) .content( EditView::new() .on_submit(show_popup) .with_id("name") .fixed_width(20), ) .button("Ok", |s| { let name = s.call_on_id( "name", |view: &mut EditView| view.get_content(), ).unwrap(); show_popup(s, &name); }), ); fn show_popup(s: &mut Cursive, name: &str) { if name.is_empty() { s.add_layer(Dialog::info("Please enter a name!")); } else { let content = format!("Hello {}!", name); s.pop_layer(); s.add_layer(Dialog::around(TextView::new(content)) .button("Quit", |s| s.quit())); } }
Methods
impl EditView
[src]
pub fn new() -> Self
[src]
Creates a new, empty edit view.
pub fn set_secret(&mut self, secret: bool)
[src]
If secret
is true
, the content won't be displayed in clear.
Only *
will be shown.
pub fn secret(self) -> Self
[src]
Hides the content of the view.
Only *
will be shown.
pub fn set_filler<S: Into<String>>(&mut self, filler: S)
[src]
Sets the character to fill in blank space.
Defaults to "_".
pub fn filler<S: Into<String>>(self, filler: S) -> Self
[src]
Sets the character to fill in blank space.
Chainable variant.
Examples
let edit = EditView::new().filler(" ");
pub fn disable(&mut self)
[src]
Disables this view.
A disabled view cannot be selected.
pub fn disabled(self) -> Self
[src]
Disables this view.
Chainable variant.
pub fn enable(&mut self)
[src]
Re-enables this view.
pub fn set_style(&mut self, style: ColorStyle)
[src]
Sets the style used for this view.
When the view is enabled, the style will be reversed.
Defaults to ColorStyle::Secondary
.
pub fn style(self, style: ColorStyle) -> Self
[src]
Sets the style used for this view.
When the view is enabled, the style will be reversed.
Chainable variant.
pub fn set_on_edit_mut<F>(&mut self, callback: F) where
F: FnMut(&mut Cursive, &str, usize) + 'static,
[src]
F: FnMut(&mut Cursive, &str, usize) + 'static,
Sets a mutable callback to be called whenever the content is modified.
callback
will be called with the view
content and the current cursor position.
Warning: this callback cannot be called recursively. If you somehow trigger this callback again in the given closure, it will be ignored.
If you don't need a mutable closure but want the possibility of
recursive calls, see set_on_edit
.
pub fn set_on_edit<F>(&mut self, callback: F) where
F: Fn(&mut Cursive, &str, usize) + 'static,
[src]
F: Fn(&mut Cursive, &str, usize) + 'static,
Sets a callback to be called whenever the content is modified.
callback
will be called with the view
content and the current cursor position.
This callback can safely trigger itself recursively if needed
(for instance if you call on_event
on this view from the callback).
If you need a mutable closure and don't care about the recursive
aspect, see set_on_edit_mut
.
pub fn on_edit_mut<F>(self, callback: F) -> Self where
F: FnMut(&mut Cursive, &str, usize) + 'static,
[src]
F: FnMut(&mut Cursive, &str, usize) + 'static,
Sets a mutable callback to be called whenever the content is modified.
Chainable variant. See set_on_edit_mut
.
pub fn on_edit<F>(self, callback: F) -> Self where
F: Fn(&mut Cursive, &str, usize) + 'static,
[src]
F: Fn(&mut Cursive, &str, usize) + 'static,
Sets a callback to be called whenever the content is modified.
Chainable variant. See set_on_edit
.
pub fn set_on_submit_mut<F>(&mut self, callback: F) where
F: FnMut(&mut Cursive, &str) + 'static,
[src]
F: FnMut(&mut Cursive, &str) + 'static,
Sets a mutable callback to be called when <Enter>
is pressed.
callback
will be given the content of the view.
Warning: this callback cannot be called recursively. If you somehow trigger this callback again in the given closure, it will be ignored.
If you don't need a mutable closure but want the possibility of
recursive calls, see set_on_submit
.
pub fn set_on_submit<F>(&mut self, callback: F) where
F: Fn(&mut Cursive, &str) + 'static,
[src]
F: Fn(&mut Cursive, &str) + 'static,
Sets a callback to be called when <Enter>
is pressed.
callback
will be given the content of the view.
This callback can safely trigger itself recursively if needed
(for instance if you call on_event
on this view from the callback).

aspect, see set_on_submit_mut
.
pub fn on_submit_mut<F>(self, callback: F) -> Self where
F: FnMut(&mut Cursive, &str) + 'static,
[src]
F: FnMut(&mut Cursive, &str) + 'static,
Sets a mutable callback to be called when <Enter>
is pressed.
Chainable variant.
pub fn on_submit<F>(self, callback: F) -> Self where
F: Fn(&mut Cursive, &str) + 'static,
[src]
F: Fn(&mut Cursive, &str) + 'static,
Sets a callback to be called when <Enter>
is pressed.
Chainable variant.
pub fn set_enabled(&mut self, enabled: bool)
[src]
