Re: Create ImageResource from URL derived from DB?
I think Nolan wants to use APIs such as
http://www.gwtproject.org/javadoc/latest/com/google/gwt/cell/client/ButtonCellBase.html#setIcon(com.google.gwt.resources.client.ImageResource)that
expect an ImageResource.

If you want to define the background image of your GWT Button widget
(which is just a button or input element), use the DOM api and CSS to
set the background to the desired image url.
String urlToImage = http://www.foo.com/your-image.png;;
Button b = new Button();
b.getElement().getStyle().setProperty(background, url(' + urlToImage +
') no-repeat);
Here is a stackoverflow post that talks about setting background images on
input elements

I have a scenario where I'd like to allow the user to give me a URL to an
image that will then be used as the Icon of a certain button later on. The
only way I know how to create an ImageResource is via a client bundle and
setting @Source. Is there another way to do this?

Create ImageResource from URL derived from DB?
Is there a way to create an ImageResource from a URL? I have a scenario where I'd like to allow the user to give me a URL to an image that will then be used as the Icon of a certain button later on. The only way I know how to create an ImageResource is via a client bundle and setting @Source.

You can also just implement the interface (or use com.google.gwt.resources.client.impl.ImageResourcePrototype, but we don't guarantee forward-compatibility with future versions of GWT) The main issue is that the code that uses ImageResource might make use of the image size, so you'd have to return accurate values for the URL. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
