public FieldLabel (String name, String text)

Parameters

name
text

Public Methods

public FieldLabel clone ()

public static FieldLabel fromJson (JSONObject json)

Parameters

json

public String getSerializedValue ()

Returns

• The value serialized into a string.

public String getText ()

Returns

• The text for this label.

public boolean setFromString (String text)

Sets the values of the field from a string.

This is used for setting values of all types of fields when loading a workspace from XML. It is also used, however, as the primary means of setting text fields (e.g., inputs, labels, dates).

There should be a concrete implementation for each field type.

Parameters

text	The text value for this field from the XML.

Returns

• True if the value was set, false otherwise.

public void setText (String newValue)

Sets the text for this label. Changes to the label will not be serialized by Blockly and should not be caused by user input. For user editable text fields use FieldInput instead.

Parameters

newValue

Protected Methods

protected void fireValueChanged (String oldText, String newText)

Notify Observers of change, without firing ChangeEvent nor as an event group, since labels are not really value fields for state changes.

Parameters

oldText	The original label text (not field value).
newText	The new label text (not field value).
