因?yàn)門reeView要增加一個(gè)彈出菜單來
Java代碼
1 private void createContextMenu(Composite parent) {
2 MenuManager mgr = new MenuManager();
3 mgr.setRemoveAllWhenShown(true);
4 final EntityTreeView tree = this;
5 mgr.addMenuListener(new IMenuListener() {

11 if(incoming.size() >0 && incoming.getFirstElement() instanceof AbstractEntity){

31 if(selectedEntity instanceof CategoryModel){
32 if ("com.test.actions.RefreshViewActionDelegate".equals(pitem.getAction().getId())){

<extension

<viewContribution
id="com.test.EntityContribution"
targetID="com.test.View">
<action
class="com.etest.actions.AddActionDelegate"
icon="icons/action.gif"
id="com.etest.actions.AddActionDelegate"
label="Add"

style="push">
</action>
targetID指定那個(gè)View會(huì)獲取到這些action
如果指定一個(gè)toolbarPath
就會(huì)在NavigatorBar顯示這些action
