【技术心得】在Eclipse RCP平台中使用Java AWT的部件

在Eclipse RCP中使用Java AWT的部件一般情况下很少会用到。特殊情况下使用也是有必要的，例如我在RCP程序中用JFreeChart显示图表的时候就会用到这种功能。示例代码如下：

public void createPartControl(Composite parent)

{

Composite awtComposite = new Composite(parent, SWT.EMBEDDED SWT.NO_BACKGROUND);

// a M$ Windows specific property that prevents some components from erasing

// their background, thus reducing window flickering (in theory :) )

try

{

System.setProperty("sun.awt.noerasebackground", "true");

} catch(NoSuchMethodError ignore){// Ignore this error}
// SWT-AWT Bridge

awtFrame = SWT_AWT.new_Frame(awtComposite);

awtPanel = new Panel(new BorderLayout())

{

public void update(Graphics g) { paint(g); } };
// Generate the Chart. Add the chart to the panel

chart = new JFreechartFactory...blabla

cp = new ChartPanel(chart);

awtFrame.add(cp);

}

以上代码片断在我的示例程序中运行成功。
