Question

当我双击树查看器文件时，文件名应出现在下一个表单视图中

Sample.dat - ＆gt;双击 - ＆gt;应该出现名称Sample.dat和File相关属性。我创建了一个treeViewer文件，然后双击未显示名称的文件名。请帮助我注意这个，eclipse rcp，Juno，e4等。

您需要向树中添加点击侦听器

final Tree tree = new Tree(parent, SWT.BORDER);
tree.addMouseListener(new MouseListener(){
    public void mouseDoubleClick(MouseEvent e) {
        //get data of selected element
        //we use array[0], because we have not multiselect tree
        MyDataObject data = (MyDataObject) tree.getSelection()[0].getData();

        //now you need to pass "data" to your view with file info
        //I don't know how to do it in pre e4 RCP apps, so
        //please read this answer: https://stackoverflow.com/a/2227764/1030113
        //hope that helps

    }
    public void mouseDown(MouseEvent e) {}
    public void mouseUp(MouseEvent e) {}
});

//to test
TreeItem treeItem1 = new TreeItem(tree, SWT.NONE);
treeItem1.setText("some item 1");
treeItem1.setData(new MyDataObject("somedata 1"));

TreeItem treeItem2 = new TreeItem(tree, SWT.NONE);
treeItem2.setText("some item 2");
treeItem2.setData(new MyDataObject("somedata 2"));

我不知道如何在pre e4 RCP应用中的视图之间进行通信，但我在这里找到了一些有用的答案：https://stackoverflow.com/a/2227764/1030113

透视课...... private void setLayouts（IPageLayout layout）{ //范围0.05f至0.95f .... IFolderLayout explorerFolderLayout = layout.createFolder（“explorer”，IPageLayout.LEFT，0.25f，layout.getEditorArea（））;

explorerFolderLayout.addView（ExplorerView.ID）;

查看课程.. viewer.addDoubleClickListener（new IDoubleClickListener（）{

        @Override
        public void doubleClick(DoubleClickEvent event) {
            // TODO Auto-generated method stub

            IStructuredSelection selection = (IStructuredSelection) viewer.getSelection();

            FileName fn = null;
            FileNameContainer fnc = null;
            if (selection.isEmpty()) 
                return;

            List<Object> list = selection.toList();...

...
