You can only do so if your Image comes from a class "imported" with an
<ui:with> *or* if you provide a @UiFactory method or
@UiField(provided=true) the imageButton field.
This would result in, either:
<ui:with field='res' type='com.company.myapp.client.SomeClass'
...
<my:MyImageButton upImage='${res.myImage}' />
or
<my:MyImageButton />
...
@UiFactory MyImageButton createMyImageButton() {
return new MyImageButton(myImage);
}
or
<my:MyImageButton field='imageButton' />
...
@UiField(provided=true) MyImageButton imageButton;
...
imageButton = new MyImageButton(myImage);
...
binder.createAndBindUi(this);
You could also replace the Image with an ImageResource so you can call
the image's resource from the ui.xml with an <ui:image/>:
<ui:image field='myImage' resource='path/to/myImage.png' />
...
<my:MyImageButton upImage='${myImage}' />
