This widget defines properties that position and size widgets in a Grid!.

See the Grid::cells property for more details.

Implementations

impl Cell

pub fn widget_new() -> Cell

Start building a new instance.

pub fn widget_type() -> WidgetType

Gets the widget type info.

impl Cell

pub fn column(&self, col: impl IntoVar<usize>)

P Cell column index.

If set to usize::MAX the cell is positioned based on the logical index.

Is 0 by default.

This property sets the INFO_ID.

See also the at property to bind both indexes at the same time.

impl Cell

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

P Cell row index.

If set to usize::MAX the cell is positioned based on the logical index.

Is 0 by default.

This property sets the INFO_ID.

See also the at property to bind both indexes at the same time.

impl Cell

pub fn at(&self, column_row: impl IntoVar<(usize, usize)>)

P Cell column and row indexes.

If set to AT_AUTO the cell is positioned based on the logical index.

Is (0, 0) by default.

This property sets the INFO_ID.

See also the column or row properties to bind each index individually.

impl Cell

pub fn column_span(&self, span: impl IntoVar<usize>)

P Cell column span.

Number of cells this one spans over horizontally, starting from the column index and spanning to the right.

Is 1 by default, the index is clamped between 1..max where max is the maximum number of valid columns to the right of the cell column index.

Note that the cell will not influence the column width if it spans over multiple columns.

This property sets the INFO_ID.

See also the span property to bind both spans at the same time.

impl Cell

pub fn row_span(&self, span: impl IntoVar<usize>)

P Cell row span.

Number of cells this one spans over vertically, starting from the row index and spanning down.

Is 1 by default, the index is clamped between 1..max where max is the maximum number of valid rows down from the cell column index.

Note that the cell will not influence the row height if it spans over multiple rows.

This property sets the INFO_ID.

See also the span property to bind both spans at the same time.

impl Cell

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

P Cell column and row span.

Is (1, 1) by default.

This property sets the INFO_ID.

See also the column_span or row_span properties to bind each index individually.

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.
