Question

我正在使用9x9 GridPane作为开发板的JavaFX Sudoku游戏，我想使网格线仅在框周围可见，因此每3行和每列一次，但是我找不到任何有效的解决方案

grid.setGridLinesVisible（true）仅具有使每一行可见的选项

我还尝试在fxml代码中为特定的列和行约束添加语句gridLinesVisible =“ true”，但不允许我将其放入。

还有其他想法吗？谢谢：D

我建议不要使用10个GridPane容器来代替整个布局，而是建议使用10个单独的GridPane容器：9个用于各个部分，1个用于容纳所有容器。

这是一个简单的FXML布局来演示（包括边界）：

<?import javafx.geometry.Insets?>

                </GridPane>
            </children>
        </GridPane>
    </children>
    <padding>
        <Insets bottom="5.0" left="5.0" right="5.0" top="5.0"/>
    </padding>
</VBox>

因此，我这里有一个3x3 GridPane，其中每个单元格为150x150像素。在这9个单元格的每个单元格中，我添加了另一个3x3 GridPane，每个单元格均为50x50。

这将创建一个统一的Sudoku网格，可供使用：
