Examples with Platform javafx.application.Platform used on opensource projects

Example 11 with Platform

use of javafx.application.Platform in project dwoss by gg-net.

the class UiCore method startJavaFx.

/**
 * Starts the Ui in JavaFx variant.
 * <p>
 * This also assumes two things:
 * <ul>
 * <li>The JavaFX Platform is already running (as a Stage already exists), most likely created through default lifecycle of javaFx</li>
 * <li>This Stage will always be open or the final to be closed, so implicitExit is ok</li>
 * </ul>
 *
 * @param <T>          type restriction.
 * @param primaryStage the primaryStage for the application, not yet visible.
 * @param builder      the build for the main ui.
