如何使用IResourceChangeListener检测文件重命名并动态设置EditorPart名称? [英] How to use an IResourceChangeListener to detect a file rename and set the EditorPart name dynamically?
问题描述
IResourceChangeListener
监听项目工作区中的更改,例如,如果编辑器零件文件名已更改。
IResourceChangeListener
listens to changes in project workspace for example if the editor part file name has changed.
我想知道如何访问特定的 EditorPart
并相应地更改其标题名称(例如,使用 .setPartName
),或者可能刷新编辑器,以便自动显示新名称。
I want to know how to access that particular EditorPart
and change its title name accordingly (e.g. with .setPartName
), or maybe the refresh the editor so that it shows the new name automatically.
理想的是,如果 IResourceChangeListener
具有重命名事件类型,但似乎不是情况。
Ideal would be if the IResourceChangeListener
has a Rename event type but does not seem to be the case.
参考问题。
推荐答案
IResourceChangeListener
使用 REMOVED
类型和 MOVED_TO
标志的组合重新命名/移动事件。您可以在 IResourceDelta
中使用
The IResourceChangeListener
does fire for rename/move events using a combination of the REMOVED
kind and a MOVED_TO
flag). You can test for that in the IResourceDelta
with
@Override
public void resourceChanged(final IResourceChangeEvent event)
{
IResourceDelta delta = event.getDelta();
// Look for change to our file
delta = delta.findMember(IPath of file being edited);
if (delta == null)
return;
if delta.getKind() == IResourceDelta.REMOVED
{
if ((delta.getFlags() & IResourceDelta.MOVED_TO) != 0)
{
IPath newPath = delta.getMovedToPath();
... handle new path
}
}
}
处理新路径的代码可能类似于:
The code to handle the new path might be something like:
IFile file = ResourcesPlugin.getWorkspace().getRoot().getFile(newPath);
if (file != null)
{
setInput(new FileEditorInput(file));
setPartName(newPath.lastSegment());
... anything else required
}
