首先,在ApplicationWorkbenchWindowAdvisor类的preWindowOpen()方法中注册我们自己定制的PresentationFactory.
Java
代码:
configurer.setPresentationFactory(new UnCloseableEditorPresentationFactory());
UnCloseableEditorPresentationFactory类继承WorkbenchPresentationFactory类,为了不影响别的GUI功能,我们只需要重写public StackPresentation createEditorPresentation(Composite parent, IStackPresentationSite site)方法中的关于设置TableFolder的部分,具体如下:
Java
代码:
DefaultTabFolder folder = new UnCloseableEditorFolder(parent, editorTabPosition | SWT.BORDER,
site.supportsState(IStackPresentationSite.STATE_MINIMIZED),
site.supportsState(IStackPresentationSite.STATE_MAXIMIZED));
…
该方法中其余部分代码,把父类的复制过来即可。
最后就是定义我们自己的UnCloseableEditorFolder了
Java代码:
public UnCloseableEditorFolder(Composite parent, int flags,boolean allowMin, boolean allowMax){
super(parent, flags, allowMin, allowMax);
}
@SuppressWarnings(“restriction”) public AbstractTabItem add(int index, int flags) {
return super.add(index, flags ^ SWT.CLOSE);
}
以上就是需要定制的代码,另外,UnCloseableEditorPresentationFactory类中,我们还可以public StackPresentation createEditorPresentation(Composite parent, IStackPresentationSite site)中定制StandardViewSystemMenu,从而去掉RCP中编辑器folder上的菜单中的close,closeall,new editor等菜单
Java代码:
class StandardEditorSystemMenu extends StandardViewSystemMenu {
/**
* @param site
*/
public StandardEditorSystemMenu(IStackPresentationSite site) {
super(site);
}
String getMoveMenuText() {
return WorkbenchMessages.EditorPane_moveEditor;
}
/* (non-Javadoc)
* @see org.eclipse.ui.internal.presentations.util.ISystemMenu#show(org.eclipse.swt.widgets.Control, org.eclipse.swt.graphics.Point, org.eclipse.ui.presentations.IPresentablePart) */
public void show(Control parent, Point displayCoordinates, IPresentablePart currentSelection) {
super.show(parent, displayCoordinates, currentSelection);
} }
以上就是个人从事RCP几年来一点小小的心得体会。
