GWT：如何仅在按钮位于面板中时触发按钮单击事件？

[英]GWT: How can I only trigger the button click event when the button is in a panel?

原文 2012-10-04 19:59:03 6 1 java/ gwt

I have a button in a horizontal panel. 我在水平面板上有一个按钮。 Both the button and panel have click handler. 按钮和面板都有单击处理程序。

When I click the button, I only want the button click handler to work but not the panel one, but it triggers both. 当我单击按钮时，我只希望按钮单击处理程序起作用，而面板不希望它起作用，但是它将触发两者。

How can I avoid triggering the panel click handler? 如何避免触发面板点击处理程序？
