嵌套
对于外部世界,每个部件都是一个黑匣。部件可以使用 IPartFactory 来创建嵌套的子代,虽然它觉得这是适宜的,但它不会将这些子代直接暴露给外部世界。以下示例演示一个具有两个嵌套子代的视图。
/**
* Example view containing a nested error log on the left and a nested
property
* view on the right.
*
* @since 3.1
*/
public class TestCompositeView {
public TestCompositeView(Composite parent, IPartFactory factory)
throws CoreException {
//
Create PDE error log view
ContainerContext
logViewContext = new ContainerContext();
ISite
logView = factory.createView(
"org.eclipse.pde.runtime.LogView",
parent, logViewContext, null);
//
Create Property view
ContainerContext
emptyContext = new ContainerContext();
ISite
propertiesView = factory.createView(IPageLayout.ID_PROP_SHEET, parent, emptyContext,
null);
// Construct layout
GridLayout layout = new GridLayout();
layout.numColumns = 2;
parent.setLayout(layout);
// Arrange error log view
GridData data1 = new GridData(GridData.FILL_BOTH);
logView.getControl().setLayoutData(data1);
// Arrange properties view
GridData data2 = new GridData(GridData.FILL_BOTH);
propertiesView.getControl().setLayoutData(data2);
}
}
