JCalendar new features in JComponentPack
- New property to control the action click count
- New client property to control the "today” button action behavior
- 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:
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:
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:
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);

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());

if(o != null) {
return new StringSelection(o.toString());
}
return null;
}
};
listView. setTransferHandler(th);
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:
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.
How to use DefaultFileFilter in JComponentPack
DefaultFileFilter provide a default file filter.
It also provides some useful methods, for example:
getExtensionNames()
Return all extension of this file filter as an array.
getExtensionName ()
Return the extension of the parameter.
It could accept 3 kinds of parameter, a File, a String, an URL.
getNameWithoutExtension(
String name)
Returns the file name without extension, for example the file "readme.txt" will return "readme", include the absolute path.
getPreferredExtensionName()
Returns the preferred extension of this file filter, actually is the
first extension of your extensions. It equal this operation
getExtensionNames()[0].
It inherits from FileFilter, have two Constructors to create a instance of the FileFilter.
DefaultFileFilter(String ext, String description)
The first parameter is extension, the second parameter is description of extension.
DefaultFileFilter(String[] ext, String description)
The first parameter are extensions, the second parameter is description of extensions.
Use JBasicChart in JComponentPack
JBasicChart provides a basic chart component.
It could draw 3 styles graph, for example: PIE, LINE, BAR.
The following code demonstrates how to use JBasicChart.
JBasicChart basicChart = new JBasicChart();
basicChart.setModel(createBasicChartModel());
basicChart.setChartType(ChartType.BAR);
private BasicChartModel createBasicChartModel_() {
double[] yaxis = {1.000, 3.000, 2, 4, 0, 3.000, 0.000, 0.000, -5.000, 4.000, 3.000};
int[] xaxis = {200701, 200612, 200611, 200610, 200609, 200608, 200607, 200606,200605, 200604, 200603};
DefaultBasicChartModel model = new DefaultBasicChartModel();
model.addSeries("a", yaxis);
for (int i = 0; i < xaxis.length; i++) {
model.setCategoryName("" + xaxis[i], i);
}
return model;
}
It is easy to use JBasicChart, you could use method setModel(model)
to change the data which displayed on the chart, and also you could use
method setChartType(type) to change the style of the chart, the
parameter type is one of the three
values(ChartType.BAR、ChartType.LINE、ChartType.PIE).
To change the data of the chart, you should learn more about DefaultBasicChartModel.
addSeries(String name,
double[] values),this method add a series values which will be y-axis
value, each value have a category name, use the method setCategoryName(String name, int categoryIndex) to set it.
addSeries(String name, double[] values, int index),when you saw this method, you should know this model could add multi-series values to it.
It also have some other methods which are easy to use, for example:
getCategoryCount()
getCategoryName(int categoryIndex)
getSeriesCount()
getSeriesName(int seriesIndex)
removeSeries(int index)
etc.
For more information, please see DefaultBasicChartModel and JBasicChart.
Use JWizardPane in JComponentPack
JWizardPane is a Java wizard component in JComponentPack.
JWizardPane usage:
Sample code
JWizardPane wizardPane = new JWizardPane();
//wizardPane.setLogoIcon(logoIcon);
//wizardPane.setLogoText(logoText);
//wizardPane.getControlButton(JWizardPane.FINISH_CONTROL).setVisible(false);
//wizardPane.getControlButton(JWizardPane.HELP_CONTROL).setVisible(false);
JPanel firstPage = new JPanel(); // firstPage: the page you want to show first.
JPanel secondPage = new JPanel();
JPanel thirdPage = new JPanel();
JPanel endPage = new JPanel();
wizardPane.addPage(firstPage);
wizardPane.addPage(secondPage);
wizardPane.addPage(thirdPage);
wizardPane.addPage(endPage);
wizardPane.showFrame(“title”);
If you want to do some operations on one page, you could implement
WizardPage interface, its methods will be called automatic when click
the Next and Finish button.
The WizardPage interface have two methods:
beforeAction(JWizardPane wizardPane, WizardAction arg0)
afterAction(JWizardPane wizardPane, WizardAction arg0)
Here is an example to implement beforeAction method.
@Override
public void beforeAction(JWizardPane wizardPane, WizardAction arg0) throws ActionVetoException
{
if (arg0 == WizardAction.NEXT || arg0 == WizardAction.FINISH) {
//write the code you want to do.
}
}
Also you could implement other operations use WizardListener, for more
information, please see WizardListener in the JComponentPack.
You could obtain the Button in the wizard panel use the method
getControlButton(int buttonType), parameter must be the following value.
JWizardPane.BACK_CONTROL, for back button
JWizardPane.NEXT_CONTROL, for next button
JWizardPane.FINISH_CONTROL, for finish button
JWizardPane.HELP_CONTROL, for help button
JWizardPane.CANCEL_CONTROL, for cancel button.
It have two way to show.one is showDialog,the other is showFrame.
showDialog(Component parent)
Pops up a dialog contains the JWizardPane and parented to parent with the dialog having a default title.
showDialog(Component parent, String title)
Pops up a dialog contains the JWizardPane and parented to parent with the dialog use the special title.
showFrame()
Pops up a frame contains the JWizardPane with the frame having a default title
showFrame(String title)
Pops up a frame contains the JWizardPane and with the frame use the special title.
If you want to pause the wizard page at current page, just throw a ActionVetoException is ok.
throw new ActionVetoException();
It also provide other functions, For more information, please see JWizardPane .
