Eclipse插件开发学习笔记【5】--- 给视图添加下拉菜单和按钮
Eclipse插件开发学习笔记【5】--- 给视图添加下拉菜单和按钮
我们采用上篇中的示例，需要在View2中添加两个按钮和下拉菜单中添加两项。
首先，新建一个继承ActionGroup类，AddActionGroup，具体代码如下：
/**

public void fillActionBars(IActionBars bars) {
if(bars == null) return;
IToolBarManager manager = bars.getToolBarManager();
manager.add(new Action1(){@Override
public void run() {
MessageDialog.openInformation(null, "", "Action1");
}
});
manager.add(new Action1(){@Override
public void run() {
MessageDialog.openInformation(null, "", "Action2");
}
});
}
public void fillContextMenu(IMenuManager menu) {
if(menu == null) return;
menu.add(new Action1(){@Override
public void run() {
MessageDialog.openInformation(null, "", "Action1");
}
});
menu.add(new Action1(){@Override
public void run() {
MessageDialog.openInformation(null, "", "Action2");
}
});
}
private class Action1 extends Action{
public Action1() {
ImageDescriptor img = WorkbenchImages.getImageDescriptor(IWorkbenchGraphicConstants.IMG_DTOOL_NEW_FASTVIEW);
setHoverImageDescriptor(img);
setText("Action1");
}
@Override
public void run() {
// TODO 自动生成的方法存根
super.run();
}
}
private class Action2 extends Action{
public Action2() {
ImageDescriptor img = WorkbenchImages.getImageDescriptor(IWorkbenchGraphicConstants.IMG_ETOOL_EDITOR_TRIMPART);
setHoverImageDescriptor(img);
setText("Action2");
}
@Override
public void run() {
// TODO 自动生成的方法存根
super.run();
}
}
}

点击运行，效果如图：
