因此,我對JavaFX相當陌生,並且正在嘗試使用透明背景和兩個紅色圓圈創建應用程序。當我將鼠標懸停在我的任務欄中的應用程序圖標上時,會出現圓圈(在小預覽窗口中),但不顯示在屏幕上。在屏幕上顯示畫布時遇到問題JavaFX
編輯:使用屏幕類而不是awt的東西修復它。
我的代碼是:
package com.razorrider7.touchgame;
import java.awt.GraphicsDevice;
import java.awt.GraphicsEnvironment;
import java.awt.Insets;
import java.awt.Rectangle;
import java.awt.Toolkit;
import java.io.File;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.canvas.Canvas;
import javafx.scene.canvas.GraphicsContext;
import javafx.scene.layout.Pane;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
import javafx.stage.StageStyle;
import com.razorrider7.touchgame.manager.SettingsManager;
public class TouchGame extends Application {
public static String dataFolder = System.getenv("APPDATA") + File.separator + "TouchGame";
@Override
public void start(Stage stage) throws Exception {
SettingsManager.setup();
initUI(stage);
}
private void initUI(Stage stage) {
stage.setResizable(false);
// Make the window transparent
stage.initStyle(StageStyle.TRANSPARENT);
Pane pane = new Pane();
double width = getBounds().getWidth(), height = getBounds().getHeight();
stage.setWidth(width);
stage.setHeight(height);
stage.setX(0);
stage.setY(0);
// Create new canvases for the left and right joysticks
Canvas joy1 = new Canvas(), joy2 = new Canvas();
joy1.setWidth(Math.rint(width/6));
joy1.setHeight(Math.rint(width/6));
joy2.setWidth(Math.rint(width/6));
joy2.setHeight(Math.rint(width/6));
joy1.setTranslateX(0);
joy1.setTranslateY(height - width/6);
joy2.setTranslateX(width - width/6);
joy2.setTranslateY(height - width/6);
// Draw the joysticks
drawJoy(joy1);
drawJoy(joy2);
pane.getChildren().add(joy1);
pane.getChildren().add(joy2);
Scene scene = new Scene(pane);
stage.setScene(scene);
stage.setTitle("TouchGame");
stage.setAlwaysOnTop(true);
stage.show();
}
private void drawJoy(Canvas canvas) {
GraphicsContext gc = canvas.getGraphicsContext2D();
gc.setStroke(Color.RED);
gc.setFill(Color.RED);
gc.fillOval(1, 1, canvas.getWidth() - 1, canvas.getHeight() - 1);
}
public Rectangle getBounds() {
GraphicsDevice gd = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();
Rectangle bounds = gd.getDefaultConfiguration().getBounds();
Insets insets = Toolkit.getDefaultToolkit().getScreenInsets(gd.getDefaultConfiguration());
Rectangle safebounds = new Rectangle(bounds);
safebounds.x += insets.left;
safebounds.y += insets.top;
safebounds.width -= (insets.left + insets.right);
safebounds.height -= (insets.top + insets.bottom);
return safebounds;
}
適合我,圓圈顯示沒問題(OS X,Java 8u72)。我建議你不要混用UI工具包,並從程序中刪除所有'java.awt'導入。此外,編程場景圖而不是畫布通常更容易。 – jewelsea
也許您可以嘗試替換您的awt代碼的等效方法是JavaFX [Screen](https://docs.oracle.com/javase/8/javafx/api/javafx/stage/Screen.html)類。 – jewelsea
是的,就是這樣。使用Screen類修復了它。謝謝! – razorrider7
