在Eclipse RCP中使用导航历史记录 [英] Use Navigation History in Eclipse RCP
问题描述
我喜欢使用Eclipse在我的RCP应用程序中提供的导航历史。不幸的是,这个功能没有很好的记录其实我只是找到这个维基条目: http://wiki.eclipse.org/FAQ_How_do_I_hook_my_editor_to_the_Back_and_Forward_buttons%3F
I like to use the navigation history provided by Eclipse in my RCP Application. Unfortunately this feature isn't well documented. In fact I only found this Wiki entry: http://wiki.eclipse.org/FAQ_How_do_I_hook_my_editor_to_the_Back_and_Forward_buttons%3F
它提到可以在导航历史记录中标记每个编辑器,而无需指定位置。这就是我想要的。
It mentions that every editor can be marked in the navigation history, without having to specify a location. This is exactly what I want.
无论特定编辑器是否支持导航历史,markLocation都可以正常工作。如果编辑器不实现INavigationLocationProvider,则会添加历史记录条目,允许用户跳回该编辑器,但不返回任何特定位置。
Regardless of whether the specific editor has any support for navigation history, markLocation will work. If the editor doesn’t implement INavigationLocationProvider, a history entry will be added, allowing the user to jump back to that editor but without returning to any particular location.
我向我的应用程序添加了以下代码行,以便在每次打开新的编辑器时添加导航条目。
I added the following lines of code to my application in order to add a navigation entry each time a new Editor is opened.
IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
IEditorPart editor = page.openEditor( input, MyEditor.ID );
page.getNavigationHistory().markLocation( editor );
我的问题是代码不起作用。命令 org.eclipse.ui.navigate.backwardHistory
和 org.eclipse.ui.navigate.forwardHistory
My problem is that the code doesn't work. The toolbar icons for the commands org.eclipse.ui.navigate.backwardHistory
and org.eclipse.ui.navigate.forwardHistory
stay grayed out.
推荐答案
我找到了解决方案。为了在Eclipse RCP应用程序中使用导航历史记录,您必须在 ApplicationActionBarAdvisor
中添加以下代码行。
I have found the solution. In order to use the Navigation History in your Eclipse RCP application you have to add the following lines of code to your ApplicationActionBarAdvisor
.
/**
* Fills the cool bar with the main toolbars for the window.
* <p>
* The default implementation does nothing. Subclasses may override.
* </p>
*
* @param coolBar
* the cool bar manager
*/
protected void fillCoolBar( ICoolBarManager coolBar ) {
IToolBarManager navigation = new ToolBarManager( SWT.FLAT );
IAction backward = getAction( IWorkbenchCommandConstants.NAVIGATE_BACKWARD_HISTORY );
IAction forward = getAction( IWorkbenchCommandConstants.NAVIGATE_FORWARD_HISTORY );
navigation.add( backward );
navigation.add( forward );
coolBar.add( navigation );
}
/**
* Instantiates the actions used in the fill methods. Use
* {@link #register(IAction)} to register the action with the key binding
* service and add it to the list of actions to be disposed when the window
* is closed.
*
* @param window
* the window containing the action bars
*/
protected void makeActions( IWorkbenchWindow window ) {
IAction backward = ActionFactory.BACKWARD_HISTORY.create( window );
backward.setId( IWorkbenchCommandConstants.NAVIGATE_BACKWARD_HISTORY );
IAction forward = ActionFactory.FORWARD_HISTORY.create( window );
forward.setId( IWorkbenchCommandConstants.NAVIGATE_FORWARD_HISTORY );
register( backward );
register( forward );
}
