[英]JavaFX transparent stage and scene
我是JavaFX的新手,我試圖創建一個透明的場景並進行階段操作,問題是當我添加諸如圖像和標簽之類的節點時,該場景不再透明了,這是我的代碼
package application;
import javafx.application.Application;
import javafx.event.EventHandler;
import javafx.fxml.FXMLLoader;
import javafx.stage.Stage;
import javafx.stage.StageStyle;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.input.MouseEvent;
public class Main extends Application {
private double xOffset = 0;
private double yOffset = 0;
public void start(Stage primaryStage) throws Exception {
try{
Parent root ;
root = FXMLLoader.load(getClass().getResource("/View/Authentification.fxml"));
primaryStage.initStyle(StageStyle.TRANSPARENT);
Scene scene = new Scene(root);
scene.setFill(null);
root.setOnMousePressed(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent event) {
xOffset = event.getSceneX();
yOffset = event.getSceneY();
}
});
root.setOnMouseDragged(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent event) {
primaryStage.setX(event.getScreenX() - xOffset);
primaryStage.setY(event.getScreenY() - yOffset);
}
});
primaryStage.setScene(scene);
primaryStage.show();}
catch(Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
launch(args);
}
}
這是我的xml代碼:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.image.Image?>
<?import javafx.scene.image.ImageView?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.text.Font?>
<AnchorPane xmlns="http://javafx.com/javafx/8.0.111" xmlns:fx="http://javafx.com/fxml/1">
<AnchorPane layoutY="94.0" prefHeight="417.0" prefWidth="363.0" style="-fx-background-color: #3D4966;"/>
<AnchorPane layoutX="-1.0" prefHeight="82.0" prefWidth="363.0" style="-fx-background-color: #3D4966;">
<children>
<Label layoutX="280.0" layoutY="70.0" text="Fermer" textFill="#eee5e5">
<font>
<Font name="System Bold" size="12.0" />
</font>
</Label>
<ImageView layoutX="288.0" layoutY="22.0" pickOnBounds="true" preserveRatio="true">
<image>
<Image url="@../images/Shutdown.png" />
</image>
</ImageView>
<Label layoutX="146.0" layoutY="61.0" prefHeight="17.0" prefWidth="92.0" text="crée un compte" textFill="#eee5e5">
<font>
<Font name="System Bold" size="12.0" />
</font>
</Label>
<ImageView layoutX="167.0" layoutY="21.0" pickOnBounds="true" preserveRatio="true">
<image>
<Image url="@../images/Add_User.png" />
</image>
</ImageView>
<ImageView layoutX="50.0" layoutY="21.0" pickOnBounds="true" preserveRatio="true">
<image>
<Image url="@../images/User.png" />
</image>
</ImageView>
<Label layoutX="50.0" layoutY="62.0" text="Ce connecter" textFill="#eee5e5">
<font>
<Font name="System Bold" size="12.0" />
</font>
</Label>
</children>
</AnchorPane>
</AnchorPane>
我嘗試了很多其他代碼,但似乎無濟於事,這些是一些帶有節點的屏幕截圖
如果創建一個或多個控件(特別是Control
任何實例或子類),則默認樣式表將應用於場景。 這#ececec
場景根的背景色設置為非透明的“非常淺灰色”(基本上比#ececec
淺26.4%)。
(具體來說,默認樣式表包含以下內容:
.root {
/***************************************************************************
* *
* The main color palette from which the rest of the colors are derived. *
* *
**************************************************************************/
/* A light grey that is the base color for objects. Instead of using
* -fx-base directly, the sections in this file will typically use -fx-color.
*/
-fx-base: #ececec;
/* A very light grey used for the background of windows. See also
* -fx-text-background-color, which should be used as the -fx-text-fill
* value for text painted on top of backgrounds colored with -fx-background.
*/
-fx-background: derive(-fx-base,26.4%);
/* ... */
-fx-background-color: -fx-background;
}
可以在http://hg.openjdk.java.net/openjfx/9/rt/file/c734b008e3e8/modules/javafx.controls/src中找到默認樣式表(在撰寫本文時)的當前版本的源代碼。 /main/resources/com/sun/javafx/scene/control/skin/modena/modena.css )。
因此,您還需要使場景的根部透明。
您可以在FXML中使用內聯CSS來執行此操作:
<AnchorPane style="-fx-background-color: transparent ;" xmlns="http://javafx.com/javafx/8.0.111" xmlns:fx="http://javafx.com/fxml/1">
或使用Java:
Parent root ;
root = FXMLLoader.load(getClass().getResource("/View/Authentification.fxml"));
root.setStyle("-fx-background-color: transparent ;");
或者您可以在外部樣式表中執行此操作:
.root {
-fx-background-color: transparent ;
}
