Examples with Button com.codename1.ui.Button used on opensource projects

Example 1 with Button

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

the class GenericListCellRenderer method extractLastClickedComponent.

/**
 * Allows partitioning the renderer into "areas" that can be clicked. When
 * receiving an action event in the list this method allows a developer to
 * query the renderer to "see" whether a button within the component was "touched"
 * by the user on a touch screen device.
 * This method will reset the value to null after returning a none-null value!
 *
 * @return a button or null
