Method Detail

assertIndex

public static void assertIndex(int size,
               int index)

Make sure the index provided as input is inside the range of possible elements of a list.

Parameters:

size - the size of the list

index - the index to be checked

addStyle

public static void addStyle(com.google.gwt.user.client.ui.UIObject object,
            Object style)

When UIObject.addStyleName(String) is invoked with an empty style name, it raises an exception. In mdl, the absence of a selector is interpreted as the default option for the behavior. For this reason, we need an alternative to UIObject.addStyleName(String) that does not raise an exception when it encounter an empty css selector.

Parameters:

object - the widget to which the css selector will be applied

style - any Object with a Object.toString() method returning the css selector to be applied.

removeStyle

public static void removeStyle(com.google.gwt.user.client.ui.UIObject object,
               Object style)

Same behavior as addStyle(UIObject, Object) but for UIObject.removeStyleName(String).

Parameters:

object - the widget to which the css selector will be applied

style - any Object with a Object.toString() method returning the css selector to be applied.
