public class GWTUiDefaults
extends Object

Defines various usefil UI related values, such as preferred spacing between elements, difference in element sizes which allows aligning them etc. Currently, the implementation is tailored to Internet Explorer. To better support other browsers, it should detect the browser we're running in and use an appropriate delegate. Also, the implementation is not complete.

Returns the preferred vertical distance between related elements.

getUnrelatedVerticalDistance

public static int getUnrelatedVerticalDistance()

Returns the preferred vertical distance between unrelated elements.

getIconLabelGap

public static int getIconLabelGap()

Returns the gap between an icon image and its label.
