I'm adding a style class to an node if it's selected and then remove it if I select other item. Even if I remove the style class the style wont refresh so it wont go back to normal state:
admin_category_label.getStyleClass().remove(admin_category_label.getStyleClass().indexOf("selected"));
admin_category_label.getStyleClass().add("clear");
but the style will stay the same as class selected
This is a bug. It is reported here Removal of hovered style class, does not update styling. You may want to vote and watch it. As a workaround you should override css rules you touched/changed to be the same as default ones. Demo:
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.layout.StackPane;
import javafx.scene.layout.VBoxBuilder;
import javafx.stage.Stage;
public class StyleDemo extends Application {
@Override
public void start(Stage primaryStage) {
final Label lbl = new Label("Style Me");
lbl.getStyleClass().add("style1"); // initial style
Button btn = new Button("Change the style");
btn.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent arg0) {
lbl.getStyleClass().remove("style1");
lbl.getStyleClass().add("style2");
}
});
StackPane root = new StackPane();
root.getChildren().add(VBoxBuilder.create().spacing(20).children(lbl, btn).build());
Scene scene = new Scene(root, 300, 250);
scene.getStylesheets().add(this.getClass().getResource("style.css").toExternalForm());
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
and the style.css is:
.style1 {
-fx-text-fill: red;
-fx-border-color: green;
-fx-font-size: 20;
}
.style2 {
-fx-text-fill: blue;
-fx-border-color: red;
-fx-font-size: 15;
-fx-underline: true;
}
when the button is clicked the initially added style1 is removed and the style2 is added.
At least for Java 8, this works now. But instead of doing what the OP did, I would achieve the same like this:
admin_category_label.getStyleClass().remove("selected");
admin_category_label.getStyleClass().add("clear");
Looks a bit cleaner.
Remember, that your CSS selectors need to look like this:
.selected {
/* Styling attributes... */
}
.clear {
/* Styling attributes... */
}
