Struct zng_wgt_grid::row::Row

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

W Grid row definition.

This widget is layout to define the actual row height, it is not the parent of the cells, only the height property affect the cells.

See the Grid::rows property for more details.

Shorthand

The Row! macro provides a shorthand init that sets the height, grid::Row!(1.lft()) instantiates a row with height of 1 leftover.

Implementations

impl Row

pub fn widget_new() -> Self

Start building a new instance.

pub fn widget_type() -> WidgetType

Gets the widget type info.

impl Row

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

P Row max height.

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

P Row min height.

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

P Row height.

impl Row

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

P If the row index is even.

Row index is zero-based, so the first row is even, the next is_odd.

impl Row

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

P If the row index is odd.

Row index is zero-based, so the first row is_even, the next one is odd.

impl Row

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

P If the row is the first.

impl Row

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

P If the row is the last.

impl Row

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

P Get the row index.

The row index is zero-based.

impl Row

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

P Get the row index and number of rows.

impl Row

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

P Get the row index, starting from the last row 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 Row

type Target = WidgetBase

The resulting type after dereferencing.

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

Dereferences the value.

impl DerefMut for Row

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

Mutably dereferences the value.
