GWT：如何使用默认（标准）styles + 用户提供的 styles？

Question

I have some combobox that is defaulted to gwt-ListBox style. I need to use this style plus my own style that I wrote in module_name.css when I use cmbobox1.setStyleName("user-defined-style");

I find that the style gwt-ListBox is ignored.

Answer 1

Use:

void addStyleName(java.lang.String style) 

Adds a secondary or dependent style name to this object.

Answer 2

With complex widgets (those who have dependant styles) like DialogBox you should use:

void setStylePrimaryName(java.lang.String style)

to set base style and update all dependant styles.

Answer 3

When you use " setStyleName " you are replacing all styles of element. When you use " addStyleName " you're adding styles to existing styles.
