[−][src]Struct cursive::views::TextArea
Multi-lines text editor.
A TextArea
will attempt to grow vertically and horizontally
dependent on the content. Wrap it in a BoxView
to
constrain its size.
Methods
impl TextArea
[src]
pub fn new() -> Self
[src]
Creates a new, empty TextArea.
pub fn get_content(&self) -> &str
[src]
Retrieves the content of the view.
pub fn cursor(&self) -> usize
[src]
Returns the position of the cursor in the content string.
pub fn set_cursor(&mut self, cursor: usize)
[src]
Moves the cursor to the given position.
Panics
This method panics if cursor
is not the beginning of a character in
the content string.
pub fn set_content<S: Into<String>>(&mut self, content: S)
[src]
Sets the content of the view.
pub fn content<S: Into<String>>(self, content: S) -> Self
[src]
Sets the content of the view.
Chainable variant.
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 enabled(self) -> Self
[src]
Re-enables this view.
Chainable variant.
pub fn is_enabled(&self) -> bool
[src]
Returns true
if this view is enabled.
