Struct CCursorRange

Source

pub struct CCursorRange {
    pub primary: CCursor,
    pub secondary: CCursor,
    pub h_pos: Option<f32>,
}

Expand description

A selected text range (could be a range of length zero).

The selection is based on character count (NOT byte count!).

Fields§

§primary: CCursor

When selecting with a mouse, this is where the mouse was released. When moving with e.g. shift+arrows, this is what moves. Note that the two ends can come in any order, and also be equal (no selection).

§secondary: CCursor

When selecting with a mouse, this is where the mouse was first pressed. This part of the cursor does not move when shift is down.

§h_pos: Option<f32>

Saved horizontal position of the cursor.

Implementations§

Source §

impl CCursorRange

Source

pub fn one(ccursor: CCursor) -> Self

The empty range.

Source

pub fn two(min: impl Into<CCursor>, max: impl Into<CCursor>) -> Self

Source

pub fn select_all(galley: &Galley) -> Self

Select all the text in a galley

Source

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

The range of selected character indices.

Source

pub fn is_empty(&self) -> bool

True if the selected range contains no characters.

Source

pub fn contains(&self, other: Self) -> bool

Is self a super-set of the other range?

Source

pub fn single(&self) -> Option<CCursor>

If there is a selection, None is returned. If the two ends are the same, that is returned.

Source

pub fn is_sorted(&self) -> bool

Source

pub fn sorted_cursors(&self) -> [CCursor; 2]

returns the two ends ordered

Source

pub fn sorted(&self) -> [CCursor; 2]

👎Deprecated: Use self.sorted_cursors instead.

Source

pub fn slice_str<'s>(&self, text: &'s str) -> &'s str

Source

pub fn on_key_press( &mut self, os: OperatingSystem, galley: &Galley, modifiers: &Modifiers, key: Key, ) -> bool

Check for key presses that are moving the cursor.

Returns true if we did mutate self.

Source

pub fn on_event( &mut self, os: OperatingSystem, event: &Event, galley: &Galley, _widget_id: Id, ) -> bool

Check for events that modify the cursor range.

Returns true if such an event was found and handled.
