    介紹JCalendar的新功能

    JCalendar new features in JComponentPack

    1. New property to control the action click count
    2. New client property to control the "today” button action behavior
    3. JCalendar works with AComboBox and add new calendar popup icon.

    1. New property to control the action click count

    JCalendar provides new property named “actionClickCount” since JComponentPack 1.1.0, use this property, you can set the mouse click count to fire the action event, JCalendar adds the following methods:
      JCalendar.getActionClickCount();
      JCalendar.setActionClickCount(int);

    2. New client property to control the "today” button action behavior

    With this new client property “JCalendar.todayButtonFireActionEventEnabled” since JComponentPack 1.1.0, the JCalendar can fire the action event when the today button clicked.

    The above new features is very important when JCalendar working with the AComboBox, the the popup JCalendar make visible, by using the above property, the popup can hidden when use click a "today” button or select a specified day.

    3. JCalendar works with AComboBox and add new calendar popup icon.

    When AComBoBox set a Date value , the popup icon automatically became a calendar icon, this is a nice feature since JComponentPack 1.1.0, see the screenshot for this feature:

    介紹JComponentPack產品中的JListView控件


    If you want to implements the Windows explorer like feature in Java swing application, the JListView component meets your requirements exactly.

    The JListView component support the 5 different view modes: small icon, large icon, list, thumbnails, details, all these view mode can change on the fly, the methods “JListView.setViewMode” can change the view mode of JListView component.

    The JListView component have the MVC design concept, a simple TableModel can be provided for it’s data, a simple CellProvider such IconProvider can be provided for it’s icon. Should write a DefaultCellRenderer subclass for its renderer and DefaultCellEditor subclass for it’s editor. The article “Introduce Cell Renderer” introduce why using the DefaultCellRenderer.

    The JListView component use a ListSelectionModel as it’s selection model, you can change the selection model’s mode, it support single selection, single interval selection, multiple interval selection, you can use the following methods to get the selected values:

          JListView.getSelectedValue(); // get the lead selection value
           JListView.getSelectedValues(); // get all selected values

    The JListView component provides several methods for it’s editing:
           JListView.isEditing(); // determines whether the JListView is being edited.
           JListView.cancelEditing(); // cancel current editing
           JListView.stopEditing(); // stop the current editing and apply the editing value
           JListView.startEditingAtIndex(); // start the editing at the specified index
           JListview.getEditingInex(); // get the current editing object’s index

    The com.zfqjava.swing.model and com.zfqjava.swing.cell package have the FileTableModel and FileProvider, it support the directory list and file icon directly, the following code can create a explorer like GUI:

           JListView listView = new JListView();
           listView.setListData(new FileTableModel(new File(System.getProperty("user.home"))));
           listView.setCellRenderer(new FileCellRenderer());
           listView.setCellEditor(new FileCellEditor());

    The JListView component also support row sorting, the TableModel you provided for JListView only need implements the ColumnSorter interface, it can support the row sorting automatically, we want to improve this area after upgrade the JRE version to 1.6.

    The JListView component provides several important client property:

    JListView.rowSelectionAllowed” allow the full row can be selected
    JListView.showVerticalLines” shows the vertical lines in details view mode.
    JListView.showHorizontalLines” shows the horizontal lines in details view mode.
    JListView.backgroundImage” sets the background image for JListView component.

    For details, you can view the JListView JavaDoc API documentation.

    The JListView also support the Drag and Drop, but in JComponentPack 1.1.0 and early version, implements this feature has trick and tips:

           // get JTable and JList
           BasicListViewUI ui = (BasicListViewUI)listView.getUI();
           JTable table = ui.getTable();
           JList list = ui.getList();
           table.setDragEnabled(true);
           list.setDragEnabled(true);
           TransferHandler th = new TransferHandler() {             
                  public int getSourceActions(JComponent c) {
                   return COPY;
            }
                  protected Transferable createTransferable(JComponent c) {
                      // just a test
                      Object o = listView.getSelectedValue();
                      if(o != null) {
                         return new StringSelection(o.toString());
                      }
                      return null;
                  }
               };
           table.setTransferHandler(th);
           list.setTransferHandler(th);

    In the upcoming version JComponentPack 1.2.0, we have improved this area, so in the new version, implements the drag and drop feature is very simple:

           listView.setDragEnabled(true);
    TransferHandler th = new TransferHandler() {
                  public int getSourceActions(JComponent c) {
                   return COPY;
            }

                  protected Transferable createTransferable(JComponent c) {
                      // just a test
                      Object o = listView.getSelectedValue();
                      if(o != null) {
                         return new StringSelection(o.toString());
                      }
                      return null;
                  }
               };
           listView. setTransferHandler(th);

    介紹JComponentPack產品中的單元格染色器和編輯器

    Introduce the cell renderer and editor in JComponentPack 1.1.0


    1. ObjectCellRenderer and it’s subclass such as DateCellRenderer, NumberCellRenderer is used by JDataGrid or JTable component, if you want to write a cell renderer for JDataGrid, you should extend ObjectCellRenderer.The ObjectCellEditor and it’s subclass is used by JDataGrid or JTable component.

    You can view these cell renderers in the com.zfqjava.swing.cell package before reinvent the wheel.
     The ObjectCellRenderer have the following subclass in com.zfqjava.swing.cell package:

    BigDecimalCellRenderer,
    BigIntegerCellRenderer,
    BooleanCellRenderer,
    DateCellRenderer,
    NumberCellRenderer,
    StreamCellRenderer,
    URLCellRenderer   
    The ObjectCellRenderer and ObjectCellEditor and it’s subclass are managed by CellManager object,
    The JDataGrid use the CellManger object to mange all it’s cell renderer and editor, so you can add the renderer and editor for CellManager, you can also remove or replace the cell renderer or editor in CellManger.

     Write a ObjectCellRenderer subclass is very simple, generally you only need override it’s “setValue(java.lang.Object value)”method.

     Writer a ObjectCellEditor subclass, you can override it’s three methods:

    protected  void  

     commitEdit()

    protected  Object  

    getValue()

    protected  void 

    setValue(Object value)

    If the editing have illegal value, you should override the “commitEdit()” method and throws a ParseException.
    You can use the method setValue(Object value) to save the edited value, and
    Override the method getValue() to return the new value.

    You can use the protected field “label” to set the text, alignment, font, etc.

    2. DefaultCellRenderer and it’s subclass such as FileCellRenderer is used by JListView component, DefaultCellEditor and it’s subclass such as FileCellEditor is used by JListView component, it works with the JListView component to provide the different view modes: small icon, large icon, list, thumbnails, details, so if you want to use JListView component, you can extend the DefaultCellRenderer.

    Write the DefaultCellRenderer and DefaultCellEditor is same as the ObjectCellRenderer and ObjectCellEditor, the different is you should use the protected field “iconLabel” and “textLabel” to set the icon and text.
