setChangeOnDrag

public void setChangeOnDrag(java.lang.Boolean changeOnDrag)

Should this sliderItem update its value and fire change handlers while the user is actively dragging the slider.

Parameters:

changeOnDrag - Default value is true

getChangeOnDrag

public java.lang.Boolean getChangeOnDrag()

Should this sliderItem update its value and fire change handlers while the user is actively dragging the slider.

Returns:

Boolean

public java.lang.Boolean getRoundValues()

Specifies whether the slider value should be rounded to the nearest integer. If set to false, values will be rounded to a fixed number of decimal places controlled by roundPrecision.

Returns:

Boolean

See Also:

Number - Slider Example

setShouldSaveValue

public void setShouldSaveValue(java.lang.Boolean shouldSaveValue)

Should this item's value be saved in the form's values and hence returned from form.getValues()?

shouldSaveValue:false is used to mark formItems which do not correspond to the underlying data model and should not save a value into the form's values. Example includes visual separators, password re-type fields, or checkboxes used to show/hide other form items.

A shouldSaveValue:false item should be given a value either via defaultValue or by calling form.setValue(item, value) or formItem.setValue(value). Providing a value via form.values or form.setValues() will automatically switch the item to shouldSaveValue:true.

Note that

• if an item is shouldSaveValue true, but has no name, a warning is logged, and shouldSaveValue will be set to false.

Overrides:

setShouldSaveValue in class CanvasItem

Parameters:

shouldSaveValue - Default value is true

getShouldSaveValue

public java.lang.Boolean getShouldSaveValue()

Should this item's value be saved in the form's values and hence returned from form.getValues()?

shouldSaveValue:false is used to mark formItems which do not correspond to the underlying data model and should not save a value into the form's values. Example includes visual separators, password re-type fields, or checkboxes used to show/hide other form items.

A shouldSaveValue:false item should be given a value either via defaultValue or by calling form.setValue(item, value) or formItem.setValue(value). Providing a value via form.values or form.setValues() will automatically switch the item to shouldSaveValue:true.

Note that

• if an item is shouldSaveValue true, but has no name, a warning is logged, and shouldSaveValue will be set to false.

Overrides:

getShouldSaveValue in class CanvasItem

Returns:

Boolean

getSlider

public Canvas getSlider()

This item is an autoChild generated Canvas displayed by the SliderItem and is an instance of Slider by default. It is customizable via the standard com.smartgwt.client.types.AutoChild pattern, by customizing sliderProperties and sliderConstructor.

For an overview of how to use and configure AutoChildren, see Using AutoChildren.

Returns:

Canvas

setVertical

public void setVertical(java.lang.Boolean vertical)

Indicates whether this is a vertical or horizontal slider.

Parameters:

vertical - Default value is false

See Also:

Slider Example

getVertical

public java.lang.Boolean getVertical()

Indicates whether this is a vertical or horizontal slider.

Returns:

Boolean

See Also:

Slider Example

setDefaultProperties

public static void setDefaultProperties(SliderItem sliderItemProperties)

Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties of the class instance passed to this function. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

Parameters:

sliderItemProperties - properties that should be used as new defaults when instances of this class are created

getValueAsFloat

public java.lang.Float getValueAsFloat()

Return the value tracked by this form item.

Returns:

value of this element
