Example 6 with Form

use of com.codename1.ui.Form in project CodenameOne by codenameone.

the class LazyValueC method showForm.

/**
 * This method is equivalent to the internal navigation behavior, it adds
 * functionality such as the back command into the given form resource and
 * shows it. If the source command is the back command the showBack() method
 * will run.
 *
 * @param resourceName the name of the resource for the form to show
 * @param sourceCommand the command of the resource (may be null)
 * @return the form thats being shown, notice that you can still manipulate
 * some states of the form before it actually appears
