Example 17 with Motion

use of com.codename1.ui.animations.Motion in project CodenameOne by codenameone.

the class Component method growShrink.

/**
 * Grows or shrinks this component to its new preferred size, this method
 * essentially takes a component whose preferred size has changed and creates a "growing"
 * effect that lasts for the duration. Notice that some components (such as text areas)
 * don't report proper preferred size untill they are laid out once. Hence the first time
 * around a text area (or container containing a text area) will not produce the expected
 * effect. This can be solved by invoking revalidate before the call to this method only the
 * first time around!
 *
 * @param duration the duration in milliseconds for the grow/shrink animation
 */
