Crate ferroui_treedatagrid_core 

The framework-neutral part of FerroUI’s TreeDataGrid, ported from the TreeDataGrid.Core project of TreeDataGrid (https://github.com/wieslawsoltes/TreeDataGrid): sources of flat and hierarchical data, their columns and rows, sorting, expansion, and row and cell selection. The control that shows them is ferroui-controls-treedatagrid (docs/porting/treedatagrid.md).

Modules

accessor

Accessors: what the reference reads from Expression<Func<TModel, TValue>>, without expression trees. A column’s value is read by a getter, written by an optional setter, named for change notifications, and observed along the objects of its path (Utils/PropertyPathObserver.cs).

items_source_view

TreeDataGridItemsSourceView.cs: the view of a collection of models that the rows and the selection read and listen to.

model_collection

The collections of models a source shows: the reference’s IEnumerable<TModel>, which the sources and the selection treat as an IList that may implement INotifyCollectionChanged.

models

Models/: columns, rows and the notifying bases.

selection

Selection/: the tree selection model and the row and cell selection of a source.

utils

Utils/.

Macros

impl_column_base

Implements IColumn for a type that holds a ColumnBase in the field base.

index_path

new IndexPath(a, b, ...).

Structs

CellIndex

A cell of a TreeDataGrid source: the index of its column in the source’s columns and the hierarchical index of its row’s model in the data.

FlatTreeDataGridSource

A source of a flat grid: one row per model.

GridLength

A length that is a size in pixels, a weighted share of the remaining space (*) or determined by the content (Auto).

HierarchicalTreeDataGridSource

A source of a tree with columns: the rows of the root models, each expandable to the rows of its children through the expander column.

IndexPath

A path of indexes into a hierarchy: one index for a row of a flat source or a root row, one more per level below. The empty path (IndexPath::UNSELECTED, the default) is no row.

RowMoveEffects

The effects of a move of rows ([Flags] RowMoveEffects).

Enums

GridUnitType

The unit of a GridLength.

RowDropPosition

Where a dragged row is dropped relative to the target row.

Traits

ITreeDataGridSource

A source of a tree data grid, untyped (ITreeDataGridSource).

ITreeDataGridSourceOf

A source of models of M (ITreeDataGridSource<TModel>).

Functions

downcast_source

The source of a shared source as the concrete source type T.

register_types

Registers the markup metadata of the enumerations of the crate and their nullable forms with the untyped value conversions. Cheap and idempotent; the control crate calls it from its register_types.

Type Aliases

RowEventHandler

A handler of the row events of a hierarchical source.
