拾色器为您提供标准的调色板,您可以选择所需的颜色。您可以通过实例化javafx.scene.control.ColorPicker类来创建颜色选择器。
以下示例演示了ColorPicker的创建。
import javafx.application.Application; import javafx.geometry.Insets; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.control.ColorPicker; import javafx.scene.control.Label; import javafx.scene.layout.HBox; import javafx.scene.paint.Color; import javafx.scene.text.Font; import javafx.scene.text.FontPosture; import javafx.scene.text.FontWeight; import javafx.stage.Stage; public class ColorPickerExample extends Application { public void start(Stage stage) { //Setting the label Label label = new Label("Select Desired Color:"); Font font = Font.font("verdana", FontWeight.BOLD, FontPosture.REGULAR, 12); label.setFont(font); //Creating a Color picker ColorPicker picker = new ColorPicker(); //Creating a hbox to hold the pagination HBox hbox = new HBox(); hbox.setSpacing(20); hbox.setPadding(new Insets(25, 50, 50, 60)); hbox.getChildren().addAll(label, picker); //Setting the stage Group root = new Group(hbox); Scene scene = new Scene(root, 595, 300, Color.BEIGE); stage.setTitle("Color Picker"); stage.setScene(scene); stage.show(); } public static void main(String args[]){ launch(args); } }
输出结果
