Question

in my ui.xml, i have style like below

<ui:style src="../teststyle.css" />

if i want to programmatically use the style inside java file rather than ui.xml, in my widget how to call .setStyleName(..) as the css is obfuscated

Answer 1

You need to do the following steps to use the styles in your view class:

• Define a interface that extends CssResource in your view class

interface Style extends CssResource {

    String myStyle();

}

• Add a ui field of that type you just defined in your view class

@UiField
Style style;

• In your ui.xml add the type attribute to your <ui:style> element (the type must match the interface of step 1):

<ui:style type="com.example.MyView.Style">

• For each of the css classes you want to access in your view class you need to add a method to the Style interface (as done with myStyle())

• You can now access the style via the style field (style.myStyle())

Hope that helps.
