我想在TableCell中应用ControlsFx装饰,因此希望将它们应用于Label。
以下内容不适用于标签的装饰。应该吗?
import org.controlsfx.control.decoration.Decorator;
import org.controlsfx.control.decoration.GraphicDecoration;
import org.controlsfx.validation.decoration.GraphicValidationDecoration;
import javafx.application.Application;
import javafx.geometry.Pos;
import javafx.scene.Node;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.stage.Stage;
public class LabelDecoration extends Application {
private static final Image REQUIRED_IMAGE = new Image(GraphicValidationDecoration.class.getResource("/impl/org/controlsfx/control/validation/required-indicator.png").toExternalForm()); //$NON-NLS-1$
@Override
public void start(Stage primaryStage) throws Exception {
Label label = new Label("Test");
Node requiredDecoration = new ImageView( REQUIRED_IMAGE );
Decorator.addDecoration( label, new GraphicDecoration( requiredDecoration, Pos.TOP_LEFT ));
primaryStage.setScene( new Scene( label, 100, 100 ));
primaryStage.show();
}
public static void main(String[] args) {
launch( args );
}
}
答案 0 :(得分:1)
装饰器尝试将 DecorationPane 安装到场景中,但在您的情况下还不存在。
将 Decorator.addDecoration(...)行包装在 Platform.runLater(...)中,它会起作用。
