public interface IColumn<I extends IAnyGroup>
extends IHeaderElement<IColumn<I>>, IChildable<IColumn<I>,I>

Immutable Column component

A single column in a IColumns component. Each child of the IColumn component is placed in each successive cell of the grid. The column with the most child elements determines the number of rows in each column.

The use of column is mainly to define attributes for each cell in the grid.

Support @Action

Name	Action Type
onSort	ActionData: SortData Denotes user has sorted the row of this column.
onGroup	ActionData: SortData Denotes user has grouped all the cells under a column. [ZK PE]
onUngroup	ActionData: SortData Denotes user has ungrouped all the cells under a column. [ZK EE]

Field Detail

DEFAULT

static final IColumn<IAnyGroup> DEFAULT

Constant for default attributes of this immutable component.

Method Detail

getWidgetClass

default java.lang.String getWidgetClass()

Returns the client widget class.

Default: "zul.grid.Column"

Specified by:

getWidgetClass in interface IComponent<I extends IAnyGroup>

Returns:

getSortDirection

default java.lang.String getSortDirection()

Returns the sort direction.

Default: "natural".

withSortDirection

IColumn<I> withSortDirection(java.lang.String sortDirection)

Returns a copy of this immutable component with the specified sortDirection.

Sets the sort direction. This does not sort the data, it only serves as an indicator as to how the grid is sorted. (unless the grid has IGrid.isAutosort() attribute for model case)

Parameters:

sortDirection - One of "ascending", "descending" and "natural"

Default: "natural".

Returns:

A modified copy of the this object

withSortDirection

default IColumn<I> withSortDirection(IColumn.SortDirection sortDirection)

Returns a copy of this immutable component with the specified sortDirection.

Sets the sort direction. This does not sort the data, it only serves as an indicator as to how the grid is sorted. (unless the grid has IGrid.isAutosort() attribute for model case)

Parameters:

sortDirection - One of IColumn.SortDirection

Default: IColumn.SortDirection.NATURAL.

Returns:

A modified copy of the this object
