Returns:

the number of columns to be displayed on one row

setColumnsCount

@StudioProperty
@Positive
void setColumnsCount(int columnsCount)

Sets the number of columns to be displayed on one row. The default value is taken from UiComponentProperties.getFilterColumnsCount().

getPropertiesFilterPredicate

@Nullable
Predicate<MetaPropertyPath> getPropertiesFilterPredicate()

Returns:

a properties filter predicate

setPropertiesFilterPredicate

void setPropertiesFilterPredicate(@Nullable
 Predicate<MetaPropertyPath> propertiesFilterPredicate)

Sets a predicate that tests whether a property with the given path should be available for filtering.

Parameters:

propertiesFilterPredicate - a predicate to set

addPropertiesFilterPredicate

void addPropertiesFilterPredicate(Predicate<MetaPropertyPath> propertiesFilterPredicate)

Adds a predicate to the current properties filter predicate. The result predicate is a composed predicate that represents a short-circuiting logical AND of given predicate and current properties filter predicate.

Parameters:

propertiesFilterPredicate - a predicate to add

getDataLoader

DataLoader getDataLoader()

Returns:

a DataLoader related to the filter

setDataLoader

@StudioProperty(type=DATALOADER_REF)
void setDataLoader(DataLoader dataLoader)

Sets a DataLoader related to the filter.

Parameters:

dataLoader - a DataLoader to set

isAutoApply

boolean isAutoApply()

Returns:

true if the filter should be automatically applied to the DataLoader when the value component value is changed

setAutoApply

@StudioProperty
void setAutoApply(boolean autoApply)

Sets whether the filter should be automatically applied to the DataLoader when the value component value is changed.

Parameters:

autoApply - true if the filter should be automatically applied to the DataLoader when the value component value is changed

apply

void apply()

Applies the current configuration.

getCaptionPosition

SupportsCaptionPosition.CaptionPosition getCaptionPosition()

Specified by:

getCaptionPosition in interface SupportsCaptionPosition

Returns:

caption position of filter child components

setCaptionPosition

void setCaptionPosition(SupportsCaptionPosition.CaptionPosition position)

Sets caption position of filter child components.

• SupportsCaptionPosition.CaptionPosition.LEFT - component captions will be placed in a separate column on the left side of the components
• SupportsCaptionPosition.CaptionPosition.TOP - component captions will be placed above the components

Specified by:

setCaptionPosition in interface SupportsCaptionPosition

Parameters:

position - caption position of filter child components

getCaptionWidth

float getCaptionWidth()

Returns:

caption width of filter child components

getCaptionWidthSizeUnit

SizeUnit getCaptionWidthSizeUnit()

Returns:

caption width size unit of filter child components

setCaptionWidth

void setCaptionWidth(String width)

Sets caption width of filter child components.

Parameters:

width - caption width of filter child components

addConfiguration

DesignTimeConfiguration addConfiguration(String id,
 @Nullable
 String name)

Adds design-time configuration with given id and name. A configuration is a set of FilterComponents. The configuration does not store a reference to all components, but stores a reference only to the root element LogicalFilterComponent from which the rest FilterComponents can be obtained. The root LogicalFilterComponent is generated with a LogicalFilterComponent.Operation.AND operation.

The configuration defined in XML is a DesignTimeConfiguration.

Parameters:

id - a configuration id. Must be unique within this filter

name - a configuration name

Returns:

DesignTimeConfiguration

See Also:

• LogicalFilterComponent

addConfiguration

DesignTimeConfiguration addConfiguration(String id,
 @Nullable
 String name,
 LogicalFilterComponent.Operation rootOperation)

Adds design-time configuration with given id and name. A configuration is a set of FilterComponents. The configuration does not store a reference to all components, but stores a reference only to the root element LogicalFilterComponent from which the rest FilterComponents can be obtained. The root LogicalFilterComponent is generated with a given operation.

The configuration defined in XML is a DesignTimeConfiguration.

Parameters:

id - a configuration id. Must be unique within this filter

name - a configuration name

rootOperation - an operation of root LogicalFilterComponent

Returns:

DesignTimeConfiguration
