                           Canvas defaults)

Changes the defaults for Canvas AutoChildren named autoChildName.

Parameters:

autoChildName - name of an AutoChild to customize the defaults for.

defaults - Canvas defaults to apply. These defaults override any existing properties without destroying or wiping out non-overridden properties.

changeAutoChildDefaults

public static void changeAutoChildDefaults(java.lang.String autoChildName,
                           FormItem defaults)

Changes the defaults for FormItem AutoChildren named autoChildName.

Parameters:

autoChildName - name of an AutoChild to customize the defaults for.

See Also:

AutoChildUsage

changePickerIconDefaults

public static void changePickerIconDefaults(FormItemIcon defaults)

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. Setting this attribute value to false will suppress any change notifications from the user dragging the slider thumb until the user releases the mouse at the final position. This can be useful to avoid repeatedly firing expensive operations such as server fetches while the user drags through a range of values.

Parameters:

changeOnDrag - 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. Setting this attribute value to false will suppress any change notifications from the user dragging the slider thumb until the user releases the mouse at the final position. This can be useful to avoid repeatedly firing expensive operations such as server fetches while the user drags through a range of values.

Returns:

Boolean

setDefaultValue

public void setDefaultValue(int defaultValue)

Default value for this sliderItems is 1.

Parameters:

defaultValue - defaultValue Default value is 1

getDefaultValue

public int getDefaultValue()

Default value for this sliderItems is 1.

Returns:

int

setMaxValue

public void setMaxValue(float maxValue)

The maximum slider value. The slider value is equal to maxValue when the thumb is at the top or right of the slider (unless flipValues is true, in which case the maximum value is at the bottom/left of the slider)

If this method is called after the component has been drawn/initialized: Sets the maximum value of the slider

Parameters:

maxValue - the new maximum value Note:Use Doubles rather Floats when manipulating decimal values. See gwtFloatVsDouble for details. Default value is 100

See Also:

Slider.setFlipValues(java.lang.Boolean), Number - Slider Example

getMaxValue

public float getMaxValue()

The maximum slider value. The slider value is equal to maxValue when the thumb is at the top or right of the slider (unless flipValues is true, in which case the maximum value is at the bottom/left of the slider)

Returns:

float

See Also:

Slider.getFlipValues(), Number - Slider Example

setMinValue

public void setMinValue(float minValue)

The minimum slider value. The slider value is equal to minValue when the thumb is at the bottom or left of the slider (unless flipValues is true, in which case the minimum value is at the top/right of the slider)

If this method is called after the component has been drawn/initialized: Sets the minimum value of the slider

Parameters:

minValue - the new minimum value Note:Use Doubles rather Floats when manipulating decimal values. See gwtFloatVsDouble for details. Default value is 1

See Also:

Slider.setFlipValues(java.lang.Boolean), Number - Slider Example

getMinValue

public float getMinValue()

The minimum slider value. The slider value is equal to minValue when the thumb is at the bottom or left of the slider (unless flipValues is true, in which case the minimum value is at the top/right of the slider)

Returns:

float

See Also:

Slider.getFlipValues(), Number - Slider Example

setNumValues

public void setNumValues(java.lang.Integer numValues)

The number of discrete values represented by slider. If specified, the range of valid values (between minValue and maxValue) will be divided into this many steps. As the thumb is moved along the track it will only select these values and appear to jump between the steps.

If this method is called after the component has been drawn/initialized: Sets the number of values for the slider

Parameters:

numValues - the new number of values Note:Use Doubles rather Floats when manipulating decimal values. See gwtFloatVsDouble for details. Default value is null

See Also:

Number - Slider Example

getNumValues

public java.lang.Integer getNumValues()

The number of discrete values represented by slider. If specified, the range of valid values (between minValue and maxValue) will be divided into this many steps. As the thumb is moved along the track it will only select these values and appear to jump between the steps.

Returns:

Integer

See Also:

Number - Slider Example

setRoundPrecision

public void setRoundPrecision(int roundPrecision)

If roundValues is false, the slider value will be rounded to this number of decimal places. If set to null the value will not be rounded

Parameters:

roundPrecision - roundPrecision Default value is 1

See Also:

Number - Slider Example

getRoundPrecision

public int getRoundPrecision()

If roundValues is false, the slider value will be rounded to this number of decimal places. If set to null the value will not be rounded

Returns:

int

See Also:

Number - Slider Example

setRoundValues

public void setRoundValues(java.lang.Boolean roundValues)

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.

Parameters:

roundValues - roundValues Default value is true

See Also:

Number - Slider Example

getRoundValues

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

public void setVertical(java.lang.Boolean vertical)

Indicates whether this is a vertical or horizontal slider.

Parameters:

vertical - 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 subsequent instances of this class will automatically have the default properties that were set when this method was called. 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 effect 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.

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
