We *_*org 10 css java webkit javafx javafx-webengine
我正在开发一个JavaFX应用程序,它包含很少的html,css,JS文件,这些文件由内部webkit浏览器呈现.现在,问题是我们在JavaFX提供的webkit浏览器中没有得到平滑渲染的CSS动画,但Firefox或chrome中的相同代码相当平滑.
此外,没有持久性可用(目前在Java中使用变量,并通过JS进行持久性通信).
我正在寻找的是有任何方法来集成一些无头浏览器,或一些设置,使CSS动画更顺畅.我遇到的唯一问题是JxBrowser,但对于个人使用来说太昂贵了.
代码:
public class Main extends Application {
private Scene scene;
MyBrowser myBrowser;
String completeText = "";
@Override
public void start(Stage primaryStage) throws Exception{
primaryStage.setTitle("Frontend");
java.net.CookieManager manager = new java.net.CookieManager();
java.net.CookieHandler.setDefault(manager);
myBrowser = new MyBrowser();
scene = new Scene(myBrowser, 1080, 1920);
primaryStage.setScene(scene);
primaryStage.setFullScreen(true);
primaryStage.show();
// @ being the escape character
scene.setOnKeyTyped(new EventHandler<KeyEvent>() {
@Override
public void handle(KeyEvent event) {
String text = event.getCharacter();
if (text.equals("0")) {
String tempText = completeText;
completeText = "";
processText(tempText);
}else {
completeText = completeText+text;
}
}
});
}
}
MyBrowser:
public class MyBrowser extends Region {
public MyBrowser() {
webEngine.getLoadWorker().stateProperty().addListener((observable, oldValue, newValue) -> {
if (newValue == Worker.State.SUCCEEDED) {
JSObject window = (JSObject) webEngine.executeScript("window");
window.setMember("app", this);
}
});
URL urlHello = getClass().getResource(hellohtml);
webEngine.load(urlHello.toExternalForm());
webView.setPrefSize(1080, 1920);
webView.setContextMenuEnabled(false);
getChildren().add(webView);
}
包含动画的CSS代码:
#ball-container.go #ball{
-webkit-animation: rotating-inverse 2s ease-out 0s 1 normal;
animation: rotating-inverse 2s ease-out 0s 1 normal;
}
#ball-container {
height: 102px;
width: 102px;
position: absolute;
top: -95px;
left: 480px;
-webkit-transition: all 0.9s ease-in-out 0s;
transition: all 0.9s ease-in-out 0s;
}
#ball-container.shake .ball-wrapper{
-webkit-animation: yAxis 0.9s ease-in-out;
animation: yAxis 0.9s ease-in-out;
}
谢谢.
尝试使用Java 8u112，根据您的代码我创建了一个工作示例（使用 Java JDK 8u112 64 位进行测试）：
import javafx.application.Application;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;
import javafx.stage.Stage;
public class Example extends Application
{
public static void main(String[] args)
{
launch(args);
}
class MyBrowser extends Parent
{
private WebEngine webEngine;
private WebView webView;
public MyBrowser()
{
webView = new WebView();
webEngine = webView.getEngine();
// Ugly (but easy to share) HTML content
String pageContents =
"<html>"
+ "<head>"
+ "<style>"
+ "@-webkit-keyframes mymove {"
+ "from {top: 0px;}"
+ "to {top: 50px;}"
+ "}"
+ ".box { "
+ "width: 150px; "
+ "position: relative; "
+ "height: 150px; "
+ "background: red; "
+ "margin-top: 35px; "
+ "margin-left: auto; "
+ "margin-right: auto; "
+ "-webkit-transition: background-color 2s ease-out; "
+ "-webkit-transition: all 1s ease-in-out; "
+ "}"
+".box:hover {"
+" background-color: green;"
+ "width:350px;"
+ "-webkit-animation: mymove 1s infinite;"
+"}"
+ "</style>"
+ "</head>"
+ "<body>"
+ "<div class='box'></div>"
+ "</body>"
+ "</html>";
webEngine.loadContent(pageContents);
webView.setContextMenuEnabled(false);
getChildren().add(webView);
}
}
private Scene scene;
MyBrowser myBrowser;
@Override
public void start(Stage primaryStage) throws Exception
{
primaryStage.setTitle("Frontend");
myBrowser = new MyBrowser();
scene = new Scene(myBrowser);
primaryStage.setScene(scene);
primaryStage.show();
}
}
我怀疑这是因为他们现在使用的是较新的 webkit JDK-8156698，但之前可能是一个错误（您可以查看8u112 错误修复列表）。
