java - Eclipse 项目属性/首选项页面 : How to find event of opening preference page in project property window(Eclipse)

Question

我想在页面打开时初始化首选项页面上的某些字段值我希望每次在项目属性窗口(Eclipse)中打开页面时都有它。

Answer 1

尝试实现属性更改监听器。

这可能有帮助-

public class MyFieldEditorPreferencePage extends PropertyPage {
private Text text;

public void initialize() {
    // TODO Auto-generated constructor stub
    IProject project = (IProject) getElement().getAdapter(IProject.class);

    final IPreferenceStore store = Activator
            .getImpaktPreferenceStore(project);

    store.addPropertyChangeListener(new IPropertyChangeListener() {

        @Override
        public void propertyChange(
                org.eclipse.jface.util.PropertyChangeEvent event) {
            // TODO Auto-generated method stub

            // TODO Auto-generated method stub

            if (text != null && !text.isDisposed())
                text.setText(store.getString("key"));

        }
    });

    setPreferenceStore(store);

}

@Override
protected Control createContents(Composite parent) {
    // TODO Auto-generated method stub

    initialize();
    GridLayout layout = new GridLayout(1, false);
    parent.setLayout(layout);
    GridData gridData = new GridData(SWT.FILL, SWT.FILL, true, true);

    Composite container = new Composite(parent, 0);
    container.setLayoutData(gridData);

    GridLayout containerLayout = new GridLayout(2, false);
    container.setLayout(containerLayout);
    Label lbl = new Label(container, 0);
    lbl.setText("Locale");

    text = new Text(container, SWT.BORDER);
    text.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false, 1, 1));

    text.setText(getPreferenceStore().getString("impakt.properties.locale"));

    return parent;
}

}
