Struct zng_wgt_grid::column::Column

pub struct Column(/* private fields */);

W Grid column definition.

This widget is layout to define the actual column width, it is not the parent of the cells, only the width and align properties affect the cells.

See the Grid::columns property for more details.

Shorthand

The Column! macro provides a shorthand init that sets the width, grid::Column!(1.lft()) instantiates a column with width of 1 leftover.

Implementations

impl Column

pub fn widget_new() -> Self

Start building a new instance.

pub fn widget_type() -> WidgetType

Gets the widget type info.

impl Column

pub fn max_width(&self, max: impl IntoVar<Length>)

P Column max width.

pub fn min_width(&self, min: impl IntoVar<Length>)

P Column min width.

pub fn width(&self, width: impl IntoVar<Length>)

P Column width.

impl Column

pub fn is_even(&self, state: impl IntoVar<bool>)

P If the column index is even.

Column index is zero-based, so the first column is even, the next is_odd.

impl Column

pub fn is_odd(&self, state: impl IntoVar<bool>)

P If the column index is odd.

Column index is zero-based, so the first column is_even, the next one is odd.

impl Column

pub fn is_first(&self, state: impl IntoVar<bool>)

P If the column is the first.

impl Column

pub fn is_last(&self, state: impl IntoVar<bool>)

P If the column is the last.

impl Column

pub fn get_index(&self, state: impl IntoVar<usize>)

P Get the column index.

The column index is zero-based.

impl Column

pub fn get_index_len(&self, state: impl IntoVar<(usize, usize)>)

P Get the column index and number of columns.

impl Column

pub fn get_rev_index(&self, state: impl IntoVar<usize>)

P Get the column index, starting from the last column at 0.

Methods from Deref<Target = WidgetBase>

pub fn widget_builder(&mut self) -> &mut WidgetBuilder

Returns a mutable reference to the widget builder.

pub fn widget_when(&mut self) -> Option<&mut WhenInfo>

Returns a mutable reference to the when block if called inside a when block.

pub fn widget_take(&mut self) -> WidgetBuilder

Takes the widget builder, finishing the widget macro build.

After this call trying to set a property using self will panic, the returned builder can still be manipulated directly.

pub fn widget_build(&mut self) -> impl UiNode

Build the widget.

After this call trying to set a property will panic.

pub fn widget_importance(&mut self) -> &mut Importance

Returns a mutable reference to the importance of the next property assigns, unsets or when blocks.

Note that during the widget_intrinsic call this is Importance::WIDGET and after it is Importance::INSTANCE.

pub fn start_when_block( &mut self, inputs: Box<[WhenInput]>, state: Box<dyn VarBoxed<bool>>, expr: &'static str, location: SourceLocation, )

Start building a when block, all properties set after this call are pushed in the when block.

pub fn end_when_block(&mut self)

End the current when block, all properties set after this call are pushed in the widget.

pub fn id(&self, id: impl IntoValue<WidgetId>)

c Unique ID of the widget instance.

Note that the id can convert from a &'static str unique name.

Trait Implementations

impl Deref for Column

type Target = WidgetBase

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for Column

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
