[英]JavaFX: Changing CSS file outside of Main class
There is a question related to this that was already answered but I would like to know how to change the CSS file outside of the main class and inside the controller or perhaps some more appropriate classes.有一个与此相关的问题已经得到解答,但我想知道如何在主 class 和 controller 或更多合适的类之外更改 CSS 文件。
package calc;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
public class Controller {
@FXML
private void skinSelector(ActionEvent event) {
// Where the magic happens!
}
}
This will probably help you.这可能会对您有所帮助。
main.fxml主文件
<Pane fx:id="rootPane" stylesheets="@theme1.css" styleClass="pane" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/11.0.1" xmlns:fx="http://javafx.com/fxml/1" fx:controller="sample.Controller">
<children>
<Button layoutX="200.0" layoutY="200.0" onAction="#press" text="Button" />
</children>
</Pane>
Controller.java Controller.java
public class Controller {
@FXML
private Pane rootPane;
@FXML
private void press(ActionEvent actionEvent) {
rootPane.getStylesheets().clear();
rootPane.getStylesheets().add(
getClass()
.getResource("theme2.css")
.toExternalForm()
);
}
}
theme1.css主题1.css
.pane{
-fx-background-color: red;
}
theme2.css主题2.css
.pane{
-fx-background-color: black;
}
