我成功地向现有的IProject 添加了一个属性,尽管它没有实现IPropertySource(因此可以通过继承和覆盖getPropertyDescriptors 和getPropertyValue 方法来添加一些功能.
感谢 greg-449,我能够理解 StandardPropertiesAdapterFactory 的功能,它从 IProject(扩展了 IResource)生成了 ResourcePropertySource。
因此,解决所有这些问题的一种方法是使用AdvancedPropertySection 的子类来显示IProject 的属性...
这里是kewd:
我将ProjectExplorer 的视图ID 与plugin.xml 中的TabDescriptorProvider 关联起来:
<extension point="org.eclipse.ui.views.properties.tabbed.propertyContributor">
<propertyContributor
contributorId="org.eclipse.ui.navigator.ProjectExplorer"
tabDescriptorProvider="eb.tresos.bustools.connection.extraproperty.TabDescriptorProvider">
<propertyCategory
category="tabbedCategory">
</propertyCategory>
</propertyContributor>
</extension>
之后,我们定义TabDescriptorProvider,并将其链接到我们自定义的AdvancedPropertySection:
public class TabDescriptorProvider implements ITabDescriptorProvider {
@Override
public ITabDescriptor[] getTabDescriptors( IWorkbenchPart part, ISelection selection ) {
AbstractTabDescriptor[] tabs = new AbstractTabDescriptor[1];
tabs[0] = new TabDescriptor("Aww shucks, TabDescriptorTitle");
return tabs;
}
class TabDescriptor extends AbstractTabDescriptor {
String label;
/**
* Constructor
*
* @param label sets the label text of the tab
*/
TabDescriptor( String label ) {
this.label = label;
}
@SuppressWarnings("rawtypes")
@Override
public List getSectionDescriptors() {
List<SectionDescriptor> sList = new ArrayList<SectionDescriptor>();
sList.add( new SectionDescriptor( label ) );
return sList;
}
@Override
public String getCategory() {
//Stub
return "";
}
@Override
public String getId() {
//stub
return "";
}
@Override
public String getLabel() {
return "Resource";
}
}
class SectionDescriptor extends AbstractSectionDescriptor {
String section;
List<AbstractPropertySection> sectionTabs = new ArrayList<AbstractPropertySection>();
public SectionDescriptor( String section ) {
this.section = section;
}
/**
* SectionId
*/
@Override
public String getId() {
//stub
return "";
}
/**
* SectionClass
*/
@Override
public ISection getSectionClass() {
return new AuxiliaryProjectSection();
}
/**
* SectionTab
*/
@Override
public String getTargetTab() {
//stub
return "";
}
}
}
还有Section 本身:
public class AuxiliaryProjectSection extends AdvancedPropertySection {
@Override
public void setInput(IWorkbenchPart part, ISelection selection) {
if (selection instanceof StructuredSelection) {
Object firstElement = ((StructuredSelection)selection).getFirstElement();
if (firstElement instanceof IProject) {
final IProject theProject = (IProject) firstElement;
ISelection selection2 = new StructuredSelection(new ResourcePropertySource(theProject) {
@Override
public IPropertyDescriptor[] getPropertyDescriptors() {
ArrayList<IPropertyDescriptor> arrayList = new ArrayList<IPropertyDescriptor>();
IPropertyDescriptor[] array = {new PropertyDescriptor("ID-ul", "Labelul")};
arrayList.addAll(Arrays.asList(super.getPropertyDescriptors()));
arrayList.addAll(Arrays.asList(array));
return arrayList.toArray(new IPropertyDescriptor[0]);
}
@Override
public Object getPropertyValue(Object id) {
if (id.equals("ID-ul"))
return "Silly Value";
else
return super.getPropertyValue(id);
}
});
super.setInput(part, selection2);
} else {
super.setInput(part, selection);
}
}
}
}
再次感谢格雷格!
