java fx gridpane setpadding

Question

我正在尝试为我的GridPane设置填充，但每次设置填充时它都会给出错误消息：

incompatible types: java.awt.Insets cannot be converted to javafx.geometry.insets

我去的每个网站和每个搜索都声明如下所示：

grid.setPadding(new Insets(10, 10, 10, 10));

在我的代码中，我将它设置为完全相同，仅用于测试目的：

grid.setPadding(new Insets(10, 10, 10, 10));

所以我不明白为什么它不允许我写这个，我也试图研究错误信息，但没有出现。

这是我的代码：

        GridPane grid = new GridPane();
        grid.setPadding(new Insets(10, 10, 10, 10));

       label1 = new Label("Do the Triangles match");
       GridPane.setConstraints(label1, 0, 0);


       label2 = new Label("Yes or no");
       GridPane.setConstraints(label2, 1, 0);


       centerXL = new Label("Center X LEFT");
       GridPane.setConstraints(centerXL, 0, 5);

       textCenterXL = new TextField();
       GridPane.setConstraints(textCenterXL, 1, 5);


       centerXR = new Label("Center X RIGHT");
       GridPane.setConstraints(centerXL, 0, 5);

       textCenterXR = new TextField();
       GridPane.setConstraints(textCenterXR, 3, 5);

       grid.getChildren().addAll(label1, label2, centerXL, textCenterXL, centerXR, textCenterXR);

       Scene scene = new Scene(grid, 400, 600);


       window.setScene(scene);



        window.show();

    }




}

错误消息告诉您需要知道的一切：

不兼容的类型：java.awt.Insets无法转换为javafx.geometry.insets

您已导入java.awt.Insets :(您的代码中的第一个导入行）您需要javafx.geometry.Insets。
