建设者

该类包含两个构造函数。

  • public ColorInput()：使用默认参数创建ColorInput的新实例。
  • public ColorInput(double x，double y，double width，double height，Paint paint)：使用指定的参数创建ColorInput的新实例。

例：

下面的示例说明ColorInput效果的工作。

package application;
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.effect.ColorInput;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
import javafx.stage.Stage;
public class ColorInputExample extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) throws Exception {
// TODO Auto-generated method stub
ColorInput color = new ColorInput();
color.setPaint(Color.RED);
color.setHeight(100);
color.setWidth(100);
color.setX(140);
color.setY(90);
Rectangle rect = new Rectangle();
rect.setEffect(color);
Group root = new Group();
Scene scene = new Scene(root,400,300);
root.getChildren().add(rect);
primaryStage.setScene(scene);
primaryStage.setTitle("ColorInput Example");
primaryStage.show();
}
}
