在我目前的项目中,我使用eclipse插件创建了弹出菜单。以下是 plugin.xml 的代码。
<?xml version="1.0" encoding="windows-1252"?>
<?eclipse version="3.0"?>
<plugin>
<extension point="org.eclipse.emf.ecore.generated_package">
<package
uri = "http://www.xtext.org/example/mydsl/MyDsl"
class = "org.xtext.example.mydsl.myDsl.MyDslPackage"
genModel = "model/generated/MyDsl.genmodel" />
</extension>
<extension
point="org.eclipse.ui.popupMenus">
<objectContribution
id="org.xtext.example.mydsl.contribution1"
objectClass="org.eclipse.core.resources.IFile">
<menu

</objectContribution>
当我在eclipse插件应用程序上运行时,它会显示如下弹出菜单。Click here for image。问题是,如图像所示,我有四个文件 vocab.mydsl,arch.mydsl,userinteraction.mydsl和deploy.mydsl 以及四个动作(Compile Vocab.mydsl,Compile Arch。弹出菜单下的mydsl,Compile Interaction.mydsl和Compile Deploy.mydsl)。现在,我希望自定义操作,当我点击 vocab.mydsl 时,它应仅显示Compile Vocab.mydsl 弹出菜单中的动作类似于我在arch.mydsl中单击时应该只显示Compile Arch.mydsl等。我已根据建议进行了更改,但它显示的错误如MESSAGE Plugin org.xtext.example.mydsl, extension org.eclipse.ui.popupMenus: Unknown extension tag found: visibleWhen
。我错过了什么吗?
修改
最后使用评论来解决部分问题。更新的plugin.xml文件的内容如下:
<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.4"?>
<plugin>
<extension
point="org.eclipse.ui.menus">
<menuContribution
allPopups="false"
locationURI="menu:org.eclipse.ui.main.menu">
<command
commandId="org.xtext.example.mydsl.popup.actions.CompileVocabSpec"
defaultHandler="org.xtext.example.mydsl.popup.actions.CompileVocabSpec"
label="Compile Vocab"
style="push">
<visibleWhen
checkEnabled="false">
<iterate
ifEmpty="false"
operator="or">
<test
property="org.eclipse.core.resources.name"
value="vocab.mydsl">
</test>
</iterate>
</visibleWhen>
</command>
<command
commandId="org.xtext.example.mydsl.popup.actions.CompileArchSpec"
defaultHandler="org.xtext.example.mydsl.popup.actions.CompileArchSpec"

</command>
</menuContribution>
</extension>
</plugin>
我对这个eclipse插件开发很新。当我解除 Compile Vocab命令而不是CompileVocabSpec.java
中提到的执行的操作时。 CompileVocabSpec.java
的内容如下:
package org.xtext.example.mydsl.popup.actions;
import org.eclipse.jface.action.IAction;
import org.eclipse.jface.viewers.ISelection;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.ui.IActionDelegate;
import org.eclipse.ui.IObjectActionDelegate;
import org.eclipse.ui.IWorkbenchPart;
public class CompileVocabSpec implements IObjectActionDelegate {
private Shell shell;
/**
* Constructor for Action1.
*/
public CompileVocabSpec() {
super();
}
/**
* @see IObjectActionDelegate#setActivePart(IAction, IWorkbenchPart)
*/
@Override
public void setActivePart(IAction action, IWorkbenchPart targetPart) {
shell = targetPart.getSite().getShell();
}
/**
* @see IActionDelegate#run(IAction)
*/
@Override
public void run(IAction action) {
String[] args = new String[3];
args[0] = "compile-vocab-spec";
args[1] = "C:/Template/";
// Call to Main method in ToolSuite
try {
// Main.main(args);
System.out.println("Compilation of Vocab");
} catch (Exception e) {
e.printStackTrace();
}
;
}
/**
* @see IActionDelegate#selectionChanged(IAction, ISelection)
*/
@Override
public void selectionChanged(IAction action, ISelection selection) {
}
}
这里当我解雇Compile Vocab命令时,它没有执行任何操作。我错过了什么吗?
答案 0 :(得分:2)
org.eclipse.ui.popupMenus
已被弃用且已存在很长时间。您只能设置整个objectContribution的可见性,我不认为您可以指定单个文件名。
org.eclipse.ui.menus
扩展点允许查看要控制的各个命令。
例如:
<extension
point="org.eclipse.ui.menus">
<menuContribution
allPopups="false"
locationURI="popup:org.eclipse.ui.popup.any">
<command
commandId="test.command"
label="Command Vocab"
style="push">
<visibleWhen
checkEnabled="false">
<iterate
ifEmpty="false"
operator="or">
<test
property="org.eclipse.core.resources.name"
value="vocab.mydsl">
</test>
</iterate>
</visibleWhen>
</command>
</menuContribution>
visibleWhen
元素将可见性限制在&#39; vocab.mydsl&#39;文件。
