在按钮上设置contentDisplayProperty 。
button.setContentDisplay(ContentDisplay.TOP);
这是一个可执行的示例:
import javafx.application.Application;
import javafx.event.*;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.*;
import javafx.scene.image.*;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class ButtonGraphicTest extends Application {
@Override public void start(final Stage stage) throws Exception {
final Label response = new Label();
final ImageView imageView = new ImageView(
new Image("http://icons.iconarchive.com/icons/eponas-deeway/colobrush/128/heart-2-icon.png")
);
final Button button = new Button("I love you", imageView);
button.setStyle("-fx-base: coral;");
button.setContentDisplay(ContentDisplay.TOP);
button.setOnAction(new EventHandler<ActionEvent>() {
@Override public void handle(ActionEvent event) {
response.setText("I love you too!");
}
});
final VBox layout = new VBox(10);
layout.setAlignment(Pos.CENTER);
layout.getChildren().addAll(button, response);
layout.setStyle("-fx-background-color: cornsilk; -fx-padding: 10; -fx-font-size: 20;");
stage.setScene(new Scene(layout));
stage.show();
}
public static void main(String[] args) { launch(args); }
}
