Re: onModuleLoad() Before Page Load
I'm not familiar with a lot of the things that you are using, however GWT has a method that it calls after the widget that the method is attached to is loaded. It's called onLoad(). Typically, when I've used it in the past, it's because I was extending a widget, say a Grid, and then I would override the onLoad() method. I'm not sure how you would implement it into a completely custom widget though. You might be able to put the iframe in a HTMLPanel or something, and call the onLoad() method. Either way, I think this may be what your looking for. Hope this helps!

Re: onModuleLoad() Before Page Load
Hi Ryan, This doesn't answer your question, but I was wondering why you had the velocity template initiate attaching your widgets to your spans? Another possibility is to have velocity write a list of span ids to a hidden span, and then have your GWT component (in a startup module) read that span and attach widgets to each span in turn. That's the way I do things.

Re: onModuleLoad() Before Page Load
Calling an onLoad() method for the widget would be called after the widget has loaded though. My problem is that I can't call my method from the script to tell it to create the widget in the first place. I need a way to make my HTML page know that it shouldn't do anything else until my script has finished loading so it can recognize my method. Also, the hidden iframe that is generated is all done behind the scenes by GWT, isn't it? So I can't really manipulate that in any way, I'm assuming.

Re: onModuleLoad() Before Page Load
My velocity template is in charge of dynamically creating my page. Basically I have a Velocity macro to create two DateBox widgets so that a date range may be input by a user. My macro is called whenever I am generating a page that requires a date range input. For the list of span ids, that would require all my widgets to be added in the same span, so be in the same place in the page. My page needs my widgets to be able to be embedded wherever I choose. The only way I could think of accomplishing this was creating a GWT JSNI method that takes a div id string as a parameter so it knows where to attach my widget.

Re: onModuleLoad() Before Page Load
Hi Ryan, I guess I wasn't clear about the span solution. What I mean is for the velocity template to build a span like this: span id=component-config style=display:nonecomp-111,comp-112,comp-113/span And then in the gwt component startup method, read the component- config span, split on commas, and attach components to each id found there (if it exists). Does that make a bit more sense? Dan On Aug 9, 9:56 am, Ryan McDonald ryan.mcdona...@gmail.com wrote: My velocity template is in charge of dynamically creating my page.

Re: onModuleLoad() Before Page Load
Ah, that makes more sense now, thanks. While that would work, I am trying to avoid having to hard-code a list of id's to attach my widget to. I would like my widget to be able to be reusable and not limited in the way it's used. My module contains a modified DateBox widget, and my Velocity Template creates two of them to create a date range input field. If I hard-code the list of span id's to attach my widget to, I would have to attach both DateBox widgets inside the Java code and eliminate the possibility of using only one DateBox widget in a field for just a plain date picker. If I do it in the Velocity Template, that can deal with how I lay my widget out which is the purpose of Velocity.
