在Eclipse RCP开发中,如果你的dependencies中包含了org.eclipse.ui.ide,在创建菜单栏是你会发现出现了多余的菜单项,例如"Convert Line Delimiters to"和"Last Edit Location"这两个菜单项。如何去掉这些多余的菜单项呢?
可以在你的ApplicationActionBarAdvisor类中添加如下代码(可以在makeActions方法中调用以下代码):
Java代码
/*
* 去掉因为导入依赖包(org.eclipse.ui.ide)而产生的多余的菜单项,一般
* 情况下包括三个

public void removeDuplicateAction()
{
ActionSetRegistry reg = WorkbenchPlugin.getDefault().getActionSetRegistry();
IActionSetDescriptor[] actionSets = reg.getActionSets();
// removing annoying gotoLastPosition Message.
String actionSetId = "org.eclipse.ui.edit.text.actionSet.navigation"; //$NON-NLS-1$
for (int i = 0; i <actionSets.length; i++)
{
if (!actionSets[i].getId().equals(actionSetId))
continue;
IExtension ext = actionSets[i].getConfigurationElement()
.getDeclaringExtension();
reg.removeExtension(ext, new Object[] { actionSets[i] });
}
// Removing convert line delimiters menu.
actionSetId = "org.eclipse.ui.edit.text.actionSet.convertLineDelimitersTo"; //$NON-NLS-1$
for (int i = 0; i <actionSets.length; i++)
{
if (!actionSets[i].getId().equals(actionSetId))
continue;
IExtension ext = actionSets[i].getConfigurationElement()

reg.removeExtension(ext, new Object[] { actionSets[i] });
}
actionSetId = "org.eclipse.ui.actionSet.openFiles";

continue;
IExtension ext = actionSets[i].getConfigurationElement()
.getDeclaringExtension();
reg.removeExtension(ext, new Object[] { actionSets[i] });
