我在windows中使用python下载 private final double diameter = 25;
private final LinkedList<Point2D> centers = new LinkedList<>();
private final Canvas pane1 = new Canvas(800, 600);
@Override
public void start(Stage primaryStage) throws Exception
{
System.out.println("Hello");
HBox root = new HBox();
pane1.setOnMouseClicked((MouseEvent event) ->
{
centers.add(new Point2D(event.getSceneX(), event.getSceneY()));
render();
System.out.println("Clicked");
});
VBox pane2 = new VBox(10);
pane2.setPrefSize(224, 600);
Button button1 = new Button("Clear Last Drawn");
button1.setOnMouseClicked((MouseEvent event) ->
{
if (!centers.isEmpty())
{
centers.removeLast();
render();
System.out.println("Last canvas loaded");
}
});
pane2.getChildren().addAll(button1);
pane1.setStyle("-fx-background-color: #224488");
pane2.setStyle("-fx-background-color: #224488");
root.getChildren().addAll(pane1, pane2);
Scene scene1 = new Scene(root, 1024, 600);
primaryStage.setScene(scene1);
primaryStage.setTitle("Mouse Clicker Project (Berk YATKIN)");
primaryStage.show();
}
private void render()
{
pane1.getGraphicsContext2D().clearRect(0, 0, pane1.getWidth(), pane1.getHeight());
centers.forEach((p) ->
{
pane1.getGraphicsContext2D().strokeOval(
p.getX() - (diameter / 2),
p.getY() - (diameter / 2),
diameter,
diameter);
});
}
文件。但下载的文件不是可读形式。
.doc我使用此方法获取文件，但无法读取该文件。 我尝试了很多方法，但似乎都没有。
