Implementations

impl DateInputState

pub fn new<S: AsRef<str>>(pattern: S) -> Result<Self, Error>

pub fn new_loc<S: AsRef<str>>(pattern: S, locale: Locale) -> Result<Self, Error>

pub fn format(&self) -> &str

chrono format string.

pub fn locale(&self) -> Locale

chrono locale.

pub fn set_format<S: AsRef<str>>(&mut self, pattern: S) -> Result<(), Error>

chrono format string.

generates a mask according to the format and overwrites whatever set_mask() did.

pub fn set_format_loc<S: AsRef<str>>( &mut self, pattern: S, locale: Locale, ) -> Result<(), Error>

chrono format string.

generates a mask according to the format and overwrites whatever set_mask() did.

pub fn set_focused(&mut self, focus: bool)

Renders the widget in focused style.

This flag is not used for event-handling.

pub fn is_focused(&mut self) -> bool

Renders the widget in focused style.

This flag is not used for event-handling.

pub fn set_invalid(&mut self, invalid: bool)

Renders the widget in invalid style.

pub fn get_invalid(&self) -> bool

Renders the widget in invalid style.

pub fn clear(&mut self)

Reset to empty.

pub fn offset(&self) -> usize

Offset shown.

pub fn set_offset(&mut self, offset: usize)

Offset shown. This is corrected if the cursor wouldn’t be visible.

pub fn cursor(&self) -> usize

Cursor position

pub fn set_cursor(&mut self, cursor: usize, extend_selection: bool) -> bool

Set the cursor position, reset selection.

pub fn set_default_cursor(&mut self)

Place cursor at decimal separator, if any. 0 otherwise.

pub fn anchor(&self) -> usize

Selection anchor.

pub fn default_value(&self) -> String

Create a default value according to the mask.

pub fn value(&self) -> Result<NaiveDate, ParseError>

Parses the text according to the given pattern.

pub fn set_value(&mut self, date: NaiveDate)

Set the date value.

pub fn is_empty(&self) -> bool

Empty

pub fn len(&self) -> usize

Length in grapheme count.

pub fn has_selection(&self) -> bool

Selection

pub fn selection(&self) -> Range<usize>

Selection

pub fn set_selection(&mut self, anchor: usize, cursor: usize) -> bool

Selection

pub fn select_all(&mut self)

Select all text.

pub fn selected_value(&self) -> &str

Selection

pub fn insert_char(&mut self, c: char) -> bool

Insert a char at the current position.

pub fn delete_range(&mut self, range: Range<usize>) -> bool

Remove the selected range. The text will be replaced with the default value as defined by the mask.

pub fn delete_next_word(&mut self) -> bool

Deletes the next word.

pub fn delete_prev_word(&mut self) -> bool

Deletes the given range.

pub fn delete_prev_char(&mut self) -> bool

Delete the char before the cursor.

pub fn delete_next_char(&mut self) -> bool

Delete the char after the cursor.

pub fn move_to_next_word(&mut self, extend_selection: bool) -> bool

pub fn move_to_prev_word(&mut self, extend_selection: bool) -> bool

pub fn move_to_next(&mut self, extend_selection: bool) -> bool

Move to the next char.

pub fn move_to_prev(&mut self, extend_selection: bool) -> bool

Move to the previous char.

pub fn move_to_line_start(&mut self, extend_selection: bool) -> bool

Start of line

pub fn move_to_line_end(&mut self, extend_selection: bool) -> bool

End of line

pub fn to_screen_col(&self, pos: usize) -> Option<u16>

Converts a grapheme based position to a screen position relative to the widget area.

pub fn from_screen_col(&self, x: usize) -> Option<usize>

Converts from a widget relative screen coordinate to a grapheme index. x is the relative screen position.

pub fn set_screen_cursor( &mut self, cursor: isize, extend_selection: bool, ) -> bool

Set the cursor position from a screen position relative to the origin of the widget. This value can be negative, which selects a currently not visible position and scrolls to it.

pub fn screen_cursor(&self) -> Option<(u16, u16)>

Screen position of the cursor for rendering.
