Field Details

DEFAULT

static final ITreecol<IAnyGroup> DEFAULT

Constant for default attributes of this immutable component.

Method Details

getWidgetClass

default String getWidgetClass()

Returns the client widget class.

Default: "zul.sel.Treecol"

Specified by:

getWidgetClass in interface IComponent<I extends IAnyGroup>

getSortDirection

default String getSortDirection()

Returns the sort direction.

Default: "natural".

withSortDirection

ITreecol<I> withSortDirection(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 tree is sorted. (unless the tree has ITree.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 ITreecol<I> withSortDirection(ITreecol.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 tree is sorted. (unless the tree has ITree.isAutosort() attribute for model case)

Parameters:

sortDirection - One of ITreecol.SortDirection

Default: ITreecol.SortDirection.NATURAL.

Returns:

A modified copy of the this object

getMaxlength

default int getMaxlength()

Returns the maximal length of each item's label.

Default: 0 (no limit).

withMaxlength

ITreecol<I> withMaxlength(int maxlength)

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

Sets the maximal length of each item's label.

Default: 0 (no limit).

Notice that maxlength will be applied to this header and all listcell of the same column.

Parameters:

maxlength - One of ITreecol.SortDirection

Default: 0.

Returns:

A modified copy of the this object

getSortAscending

@Nullable
Comparator<?> getSortAscending()

Returns the ascending sorter, or null if not available.

Default: null

withSortAscending

ITreecol<I> withSortAscending(@Nullable
 Comparator<?> sortAscending)

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

Sets the ascending sorter, or null for no sorter for the ascending order.

Parameters:

sortAscending - The comparator used to sort the ascending order.

Default: null.

Returns:

A modified copy of the this object

withSortAscending

default ITreecol<I> withSortAscending(String sortAscending)
                               throws ClassNotFoundException,
InstantiationException,
IllegalAccessException

Returns a copy of this immutable component with the specified sortAscending class name.

Sets the ascending sorter with the class name, or null for no sorter for the ascending order.
