The following application:
public class Temp extends Application {
@Override
public void start(Stage primaryStage) {
StackPane root = new StackPane();
Rectangle rect = new Rectangle(10.0,10.0);
rect.setStyle("-fx-fill: red; -fx-border-style: solid; -fx-border-width: 5; -fx-border-color: black;");
root.getChildren().add(rect);
Scene scene = new Scene(root, 100, 100);
primaryStage.setScene(scene);
primaryStage.show();
}
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
}
produces the following window:
Why doesn't my rectangle have thick black borders?
No: Rectangle
does not support -fx-border
etc: only Region
and subclasses do.
So try
public class Temp extends Application {
@Override
public void start(Stage primaryStage) {
StackPane root = new StackPane();
Region rect = new Region();
rect.setStyle("-fx-background-color: red; -fx-border-style: solid; -fx-border-width: 5; -fx-border-color: black; -fx-min-width: 20; -fx-min-height:20; -fx-max-width:20; -fx-max-height: 20;");
root.getChildren().add(rect);
Scene scene = new Scene(root, 100, 100);
primaryStage.setScene(scene);
primaryStage.show();
}
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
}
Alternatively, you can implement your border using "nested backgrounds":
rect.setStyle("-fx-background-color: black, red; -fx-background-insets: 0, 5; -fx-min-width: 20; -fx-min-height:20; -fx-max-width:20; -fx-max-height: 20;");
And you can add borders to some sides only with
rect.setStyle("-fx-background-color: black, red; -fx-background-insets: 0, 5 5 0 0; -fx-min-width: 20; -fx-min-height:20; -fx-max-width:20; -fx-max-height: 20;");
Try this style instead:
rect.setStyle("-fx-fill: red; -fx-stroke: black; -fx-stroke-width: 5;");
