GWT - How to stop propagation from a child's event to its parent

Question

I'm building a GWT application with a Tree. Every tree items represent an object which has a boolean attribute that we can set through a checkbox displayed in the tree item itself.

I have a selection handler to do some stuff on my tree which gets called on click on every tree items.

What I want to do, is to prevent selection event to firing up when I'm clicking on the checkboxes ...

However, checkboxes don't have a SelectionHandler, so I tried to put a ClickEventHandler with event.stopPropagation(), but SelectionHandler is still getting called ...

EDIT: actually SelectionHandler is getting fired before ClickEventHandler anyway ...

Thanks in advance

Answer 1

You might consider following this method provided in the GWT documentation here . That should do the bit what you are interested in.

Answer 2

尝试为复选框使用单独的单击处理程序，并在其后使用event.StopProgation（）以防止事件冒泡。

Answer 3

为了在GWT中从孩子的事件停止传播到父母，您需要使用

event.stopPropagation();
