Class DataTypeSelectionEditor

  • All Implemented Interfaces:
    java.io.Serializable, javax.swing.CellEditor
    public class DataTypeSelectionEditor
extends javax.swing.AbstractCellEditor
    An editor that is used to show the DropDownSelectionTextField for the entering of data types by name and offers the user of a completion window. This editor also provides a browse button that when pressed will show a data type tree so that the user may browse a tree of known data types.

    The typical usage of this class is in conjunction with the DataTypeChooserDialog. The dialog uses this editor as part of its DataType selection process. Users seeking a dialog that allows users to choose DataTypes are encouraged to use that dialog. If you wish to add this editor to a widget directly, then see below.

    Stand Alone Usage
    In order to use this component directly you need to call getEditorComponent(). This will give you a Component for editing.

    In order to know when changes are made to the component you need to add a DocumentListener via the addDocumentListener(DocumentListener) method. The added listener will be notified as the user enters text into the editor's text field. Then, to determine when there is as valid DataType in the field you may call validateUserSelection().

    • Method Detail

      • setPreferredDataTypeManager

        public void setPreferredDataTypeManager​(DataTypeManager dataTypeManager)
        Sets the DataTypeManager to use when the chooser is forced to parse the given data type text to resolve the data type. If the users chooses a type, then this value is not used. Note that setting this value does not restrict the parser to just the given value, but rather the given value is the preferred manager and is thus searched first.
        Parameters:
        dataTypeManager - the preferred data type manager

      • getCellEditorValue

        public java.lang.String getCellEditorValueAsText()
        Returns the text value of the editor's text field.
        Returns:
        the text value of the editor's text field.

      • getEditorComponent

        public javax.swing.JComponent getEditorComponent()
        Returns the component that allows the user to edit.

      • setDefaultSelectedTreePath

        public void setDefaultSelectedTreePath​(javax.swing.tree.TreePath path)
        Sets the initially selected node in the data type tree that the user can choose to show.
        Parameters:
        path - The path to set

      • requestFocus
