how to add same background color for all pane in javafx? - javafx-8

Question

I want to maintain single background color(black) for all panes, and for all views. i don't want write css for every view. i am using only vbox and hbox mostly. and very few table views. is there any easy way to write css once and apply to all. thank you in advance

Answer 1

You don't write a css for every view, you give every element the same style class.
Pane pane = new Pane();
pane.getStyleClass().add("bg-black-style");
Somewhere you need to add the stylesheet to the scene
scene.getStylesheets().add("css-file.css");
And in the css file
.bg-black-style {
-fx-background-color: black;
}
This way every thing that should look the same has it's style all in one place.

Answer 2

You can just use .pane in CSS class, and it will work for all the panes.
.pane{
-fx-background-color: black;
}
Same works with .button etc.

Answer 3

You can apply the style sheet to the entire application like this:
package hacks;
import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.ListView;
import javafx.scene.control.TextArea;
import javafx.scene.layout.FlowPane;
import javafx.stage.Stage;
import java.net.URL;
/**

* <br>
* CssStyle sets the style for the entire project
*/
public class CssStyle extends Application {
private String yourCss = "YourResource.css";
public CssStyle() {
try {
Application.setUserAgentStylesheet(getCss()); //null sets default style
} catch (NullPointerException ex) {
System.out.println(yourCss + " resource not found");
}
}
private Button button = new Button("Button Text");
private TextArea textArea = new TextArea("you text here");
private ObservableList<String> listItems = FXCollections.observableArrayList("one", "two", "three");
private ListView listView = new ListView<String>(listItems);
private FlowPane root = new FlowPane(button, textArea, listView);
private Scene scene = new Scene(root);
#Override
public void start(Stage primaryStage) throws Exception {
primaryStage.setScene(scene);
primaryStage.show();
}
private String getCss() throws NullPointerException {
ClassLoader classLoader = getClass().getClassLoader();
URL resource = classLoader.getResource(yourCss);
String asString = resource.toExternalForm(); //throws null
return asString;
}
}
