自定义Eclipse内容辅助的关键绑定 [英] Key-Binding for a Custom Eclipse Content Assist

问题描述

我已经实现了一个内容辅助提议计算机作为eclipse插件（使用 org.eclipse.jdt.ui.javaCompletionProposalComputer ）。我现在想绑定它自己的组合键（否则自定义提案出现在提案列表的底部）。

我尝试这样做，通过扩展 org.eclipse.ui.bindings ，但这需要定义 org.eclipse.ui.commands ，一个处理程序，可能还有更多的东西。

似乎已经有一个命令为我的自定义内容辅助计算机创建，因为它出现在键绑定菜单（在 Windows-> Preferences-> Keys 中），但是我不知道这个命令的id是什么。如果该命令在运行时创建，那么我甚至可以在我的plugin.xml中引用它的 commandId

还有另一个更简单的方法吗？

解决方案

在尝试了许多不同的实现方式后，我发现： p>

1）与自定义完成提案计算机相关联的命令为 org.eclipse.jdt.ui.specific_content_assist.command ，它在 org.eclipse.jdt.ui 插件（由eclipse提供）插件的 plugin.xml 中定义。

2）这是一个参数化的命令，这意味着它需要一个commandParameter，具有 id = org.eclipse.jdt.ui.specific_content_assist.category_id 。该参数的值应为 javaCompletionProposalComputer 的 proposalCategory 的I​​D。

以下是我如何定义自定义键绑定的示例：

 < extension point =org .eclipse.ui.bindings> 
< key 
 sequence =CTRL + ALT + SPACE
 contextId =org.eclipse.ui.contexts.dialogAndWindow
 schemeId =org.eclipse.ui。 defaultAcceleratorConfiguration
 commandId =org.eclipse.jdt.ui.specific_content_assist.command> 
< parameter 
 id =org.eclipse.jdt.ui.specific_content_assist.category_id
 value =YOUR_PROPOSAL_CATEGORY_GOES_HERE/> 
< / key> 
< / extension> 
  

无需定义新的命令或处理程序！

I've implemented a content assist proposal computer as an eclipse plugin (using org.eclipse.jdt.ui.javaCompletionProposalComputer). I would now like to bind it to it's own key combination (otherwise the custom proposals appear at the bottom of the proposal list).

I tried doing this by extending org.eclipse.ui.bindings, but this requires defining org.eclipse.ui.commands, a handler, and possibly more things.

It seems that there is already a command created for my custom content assist computer, since it appears under the key binding menu (in Windows->Preferences->Keys), but I don't know what is the id of this command. If that command is created at runtime, then can I even refer to its commandId in my plugin.xml?

Is there another, simpler way of doing this?

解决方案

After experimenting with many different ways of implementing this I found that:

1) The command associated with custom completion proposal computers is org.eclipse.jdt.ui.specific_content_assist.command, and it is defined in the plugin.xml of the org.eclipse.jdt.ui plugin (provided by eclipse).

2) This is a parametrized command, which means it takes a commandParameter with id=org.eclipse.jdt.ui.specific_content_assist.category_id. The value of this parameter should be the id of the proposalCategory for your javaCompletionProposalComputer.

Here's an example of how I defined custom key-binding:

<extension point="org.eclipse.ui.bindings">   
    <key
        sequence="CTRL+ALT+SPACE"
        contextId="org.eclipse.ui.contexts.dialogAndWindow"
        schemeId="org.eclipse.ui.defaultAcceleratorConfiguration"
        commandId="org.eclipse.jdt.ui.specific_content_assist.command">
        <parameter
            id="org.eclipse.jdt.ui.specific_content_assist.category_id"
            value="YOUR_PROPOSAL_CATEGORY_GOES_HERE"/>
    </key>
</extension> 

No need to define a new command or handler!
