马甲丁的记忆卡

IWorkbenchWindowConfigurer configurer = getWindowConfigurer();
Workbench workbench = (Workbench)configurer.getWindow().getWorkbench();
 
//        
WorkbenchKeyboard workbenchkeyboard = new WorkbenchKeyboard(workbench);        
workbenchkeyboard.openMultiKeyAssistShell();

当然workbench必需是被创建以后才可以

这样就可以show key assist出来啦～

<extension
         point="org.eclipse.ui.commands">
      <command
            categoryId="org.eclipse.ui.category.file"
            id="KeyAssist.test.save"
            name="Test Key Assist "/>
   </extension>
   <extension
         point="org.eclipse.ui.bindings">
      <key
            commandId="KeyAssist.test.save"
            contextId="org.eclipse.ui.contexts.dialogAndWindow"
            schemeId="org.eclipse.ui.defaultAcceleratorConfiguration"
            sequence="M1+Q"/>
   </extension>

定义多以上东东就可以显示自己的keyassit item啦。


终于研究出如何runtime modify keyassist了，记下这个util class

关于command这个东西，也有点bt,自定义的command会记录在runtime data里，so 第一次run可以看到的item第二次就看不到。需要在run的选项里选中clear workspace data
