Constructor Detail

NumberBox

public NumberBox(com.google.gwt.dom.client.InputElement element,
                 com.google.gwt.text.shared.Renderer<VALUE> renderer,
                 com.google.gwt.text.shared.Parser<VALUE> parser)

The constructor.

Parameters:

element - is the InputElement to wrap.

renderer - is the Renderer used to format the value.

parser - is the Parser used to parse the input as value.

Method Detail

getMinimumValue

public VALUE getMinimumValue()

This method gets the minimum value of this object. A legal value has to be greater or equal to this minimum.

Specified by:

getMinimumValue in interface AttributeReadMinimumValue<VALUE extends Number>

Returns:

the minimum allowed for value or null if unbounded.

setMinimumValue

public void setMinimumValue(VALUE minimum)

This method sets the minimum value of this object.
ATTENTION:
Changing the minimum value dynamically can invalidate the current value. This should be avoided as it may have undesired effects.

Specified by:

setMinimumValue in interface AttributeWriteMinimumValue<VALUE extends Number>

Parameters:

minimum - is the new maximum value to set. Use e.g. Integer.MAX_VALUE to unset.

getMaximumValue

public VALUE getMaximumValue()

This method gets the maximum value of this object. A legal value has to be less or equal to this maximum.

Specified by:

getMaximumValue in interface AttributeReadMaximumValue<VALUE extends Number>

Returns:

the maximum allowed for value or null if unbounded.

setMaximumValue

public void setMaximumValue(VALUE maximum)

This method sets the maximum value of this object.
ATTENTION:
Changing the maximum value dynamically can invalidate the current value. This should be avoided as it may have undesired effects.

Specified by:

setMaximumValue in interface AttributeWriteMaximumValue<VALUE extends Number>

Parameters:

maximum - is the new maximum value to set. Use e.g. Integer.MAX_VALUE to unset.
