Struct pango::TabArray

pub struct TabArray(_);

A TabArray struct contains an array of tab stops. Each tab stop has an alignment and a position.

Implementations

impl TabArray

pub fn new(initial_size: i32, positions_in_pixels: bool) -> TabArray

Creates an array of initial_size tab stops. Tab stops are specified in pixel units if positions_in_pixels is true, otherwise in Pango units. All stops are initially at position 0.

initial_size

Initial number of tab stops to allocate, can be 0

positions_in_pixels

whether positions are in pixel units

Returns

the newly allocated TabArray, which should be freed with pango_tab_array_free().

pub fn is_positions_in_pixels(&mut self) -> bool

Returns true if the tab positions are in pixels, false if they are in Pango units.

Returns

whether positions are in pixels.

pub fn size(&mut self) -> i32

Gets the number of tab stops in self.

Returns

the number of tab stops in the array.

pub fn tab(&mut self, tab_index: i32) -> (TabAlign, i32)

Gets the alignment and position of a tab stop.

tab_index

tab stop index

Returns

alignment

location to store alignment, or None

location

location to store tab position, or None

pub fn resize(&mut self, new_size: i32)

Resizes a tab array. You must subsequently initialize any tabs that were added as a result of growing the array.

new_size

new size of the array

pub fn set_tab(&mut self, tab_index: i32, alignment: TabAlign, location: i32)

Sets the alignment and location of a tab stop. alignment must always be TabAlign::Left in the current implementation.

tab_index

the index of a tab stop

alignment

tab alignment

location

tab location in Pango units

Trait Implementations
