如何执行“折叠全部折叠”在MATLAB编辑器中以编程方式？ [英] How to execute "collapse-all-folds" in the MATLAB editor programatically?

问题描述

我一直在努力解决主题中的问题比我想承认的要长一点。

I've been struggling with the problem in the subject for a bit longer than I'd like to admit.

我试图以编程方式执行相同的操作当用户点击查看> 全部折叠操作 $ c>按钮或右键单击编辑器窗口，然后代码折叠> 全部折叠。

I'm attempting to programatically execute the same Action that occurs when the user either clicks on the View > Collapse All button or right-clicks within the editor window and then Code Folding > Fold All.

到目前为止我尝试了什么：

• String 对应 Action ，可在 enum com.mathworks.mde.editor.ActionID 并且是：'collapse-all-folds'。


• 当 Action 激活时，似乎执行以下方法： org.netbeans.api.editor.fold。 FoldUtilities.collapseAll（...）（因此netbeans标签）。


• 此代码允许我获取 EditorAction的实例， ActionManager ， MatlabEditor ：

• The String that corresponds to the Action may be found in the enum com.mathworks.mde.editor.ActionID and is: 'collapse-all-folds'.
• When the Action activates, the following method seems to be executed: org.netbeans.api.editor.fold.FoldUtilities.collapseAll(...) (hence the netbeans tag).
• This code allows me to get instances of EditorAction, ActionManager, MatlabEditor:

jEd = com.mathworks.mlservices.MLEditorServices.getEditorApplication.getActiveEditor;
jAm = com.mathworks.mde.editor.ActionManager(jEd);
jAc = com.mathworks.mde.editor.EditorAction('collapse-all-folds');

我的问题是我找不到实际激活的方法行动。

My problem is that I can't find a way to actually activate the Action.

任何想法/替代品？

EDIT1 ：在这本书，我想我比以前更接近（但仍然不是那里）。引用本书：

EDIT1: After digging a bit in "the book", I think I came even closer than before (but still not quite there). Quoting from the book:

Java GUI组件通常使用 ActionMap 存储可运行的 Actions ，它们是由监听器在鼠标，键盘，属性或容器事件上调用的
。与对象方法不同，MATLAB不能直接调用 Actions 。

Java GUI components often use anActionMapto store runnableActionsthat are invoked by listeners on mouse, keyboard, property, or container events. Unlike object methods,Actionscannot be directly invoked by MATLAB.

<然后解释了一个大致涉及的解决方法：获取某种 Action 对象;创建 ActionEvent 并使用以下方法调用 Action 的 actionPerformed ActionEvent 作为参数，如下所示：

And then a workaround is explained which involves roughly: getting some sort of an Action object; creating an ActionEvent and invoking Action's actionPerformed with the ActionEvent as an argument, as implemented below:

import java.awt.event.*;
jEd = com.mathworks.mlservices.MLEditorServices.getEditorApplication.getActiveEditor;
jAm = com.mathworks.mde.editor.ActionManager(jEd);
jAc = jAm.getAction(com.mathworks.mde.editor.EditorAction('collapse-all-folds'));
jAe = ActionEvent(jAm, ActionEvent.ACTION_PERFORMED, '');
jAc.actionPerformed(jAe);

此代码运行没有错误 - 但是（似乎？）没有。我怀疑我在错误的对象上调用 ActionEvent 和 actionPerformed （ ActionManager 可能与此问题无关。）

This code runs without errors - but does (seemingly?) nothing. I suspect that I'm calling ActionEvent and actionPerformed on the wrong objects (ActionManager has possibly nothing to do with this problem at all).

PS

我知道有一个热键可以执行此操作（ Ctrl + = ），但这不是我正在寻找的（除非有一个模拟热键的命令:)）。

I know that there's a hotkey that does this (Ctrl + =), but this is not what I'm looking for (unless there's a command to simulate a hotkey press :) ).

推荐答案

经过不可估量的挖掘，试验和方式太多错误 - 我已经完成了！

After immeasurable digging, trial and way too much error - I've done it!

function FullyCollapseCurrentScript()

%// Get the relevant javax.swing.text.JTextComponent:
jTc = com.mathworks.mlservices.MLEditorServices ...
        .getEditorApplication.getActiveEditor.getTextComponent();
%// Get the FoldHierarchy for the JTextComponent:
jFh = org.netbeans.api.editor.fold.FoldHierarchy.get(jTc);
%// Finally, collapse every possible fold:
org.netbeans.api.editor.fold.FoldUtilities.collapseAll(jFh);

end

或压缩成单一，凌乱的命令：

or if compressed into a single, messy, command:

org.netbeans.api.editor.fold.FoldUtilities.collapseAll(...
org.netbeans.api.editor.fold.FoldHierarchy.get(com.mathworks. ...
mlservices.MLEditorServices.getEditorApplication.getActiveEditor. ...
getTextComponent()));

请注意，这适用于编辑器中当前打开的脚本。

Note that this works on the script currently open in the editor.
