I'd like to dynamically insert a Widget into/next to a single TreeItem, whenever a TreeItem is selected, but event handlers on the Widget never fire when I do this.
My approach so far: I dynamically manipulate the DOM of a single TreeItem, when a selection event occurs. First I insert a DIV sibling, and then I insert the Widget into that placeholder. Something like this: Button b = new Button("Click me", new ClickHandler() { public void onClick(ClickEvent event) { Window.alert("I was clicked!"); } }); Element itemDiv = treeItem.getElement(); // the TreeItem's underlying element Element spanEdit = DOM.createSpan(); // a container, perhaps this is not necessary DOM.appendChild(itemDiv, spanEdit); DOM.appendChild(spanEdit, b.getElement()); The button appears in the TreeItem when the TreeItem is selected, but I am not able to generate any click events when I try to click on the button with the mouse. I've also tried replacing the Button with direct HTML, as follows: HTML h = new HTML("<a href='javascript:alert();'>Click me for alert</ a>"); Once inserted into the TreeItem, on mouseover the browser status bar shows the link target, but clicking on it does not generate a popup. My sense is that I need to do something else when I insert an Element into the DOM, to ensure that it participates in the event handling correctly. Yes? What else do I need to do? Perhaps the Tree's SelectionHandler is interfering - a mousedown on anything within a tree's node triggers a selection event and no other events are processed? Note: This used to work for me, using GWT 1.4.62, but even then only when the inserted Widget was a Button (for all other Widget's that I tried, the click event never reached the declared handler). Note: I would prefer to do all this without manipulating the DOM, but there is a bug in TreeItem, since early version of GWT, that prohibits me from dynamically removing and later replacing the TreeItem's content. http://code.google.com/p/google-web-toolkit/issues/detail?id=2297 Thanks for any help you can provide! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
