从 gwt 中的代码触发点击事件 [英] Firing click event from code in gwt

问题描述

我在 gwt 中创建了一个自定义小部件，它扩展了复合材料.我在其中使用了焦点面板.对于 FocusPanel，我添加了 ClickHandler.然后我添加了键盘监听器.现在按下 Enter 键它应该触发点击事件.可以有没有人帮我使用 GWT 中的代码触发点击事件?

I have created a custom widget in gwt which extends the composite.I am using focus panel in that.For FocusPanel I added ClickHandler.Then I have added keyboard listner.Now on press of Enter key it should trigger click event.Can any one help me to trigger click event by using code in GWT?

focusPanel.addKeyPressHandler(new KeyPressHandler() {
            public void onKeyPress(KeyPressEvent event) {
                if (event.getNativeEvent().getKeyCode() == KeyCodes.KEY_ENTER)        {
                    // TODO call onClick() method
                }
            }
        });

谢谢

推荐答案

我没有为点击事件做过这个，但我做过这样的变更事件.

I haven't done this for a click event, but I've done change events like this.

NativeEvent event = Document.get().createChangeEvent();
DomEvent.fireNativeEvent(event, this);

[createClickEvent](http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/dom/client/Document.html#createClickEvent(int,%20int,%20int,%20int,%20int,%20boolean,%20boolean,%20boolean,%20boolean)) 方法虽然需要更多的参数.

The [createClickEvent](http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/dom/client/Document.html#createClickEvent(int,%20int,%20int,%20int,%20int,%20boolean,%20boolean,%20boolean,%20boolean)) method takes a lot more parameters though.

public final NativeEvent createClickEvent(int detail,
                                          int screenX,
                                          int screenY,
                                          int clientX,
                                          int clientY,
                                          boolean ctrlKey,
                                          boolean altKey,
                                          boolean shiftKey,
                                          boolean metaKey)
