JavaFX GridPane Changing Visibility of Specific Lines
I'm working on a JavaFX Sudoku game with a 9x9 GridPane as my board and I want to make the grid lines visible only around the boxes so every 3 rows and columns however I haven't been able to find any working solutions yet.
grid.setGridLinesVisible(true) only has the option to make every line visible
I also tried adding the statement gridLinesVisible="true" in the fxml code for the specific column and row constraints but it wouldn't allow me to put that in.
Any other ideas? Thank you :D
Solution
Instead of using one GridPane for the entire layout, I suggest using 10 separate GridPane containers: 9 for the individual sections and 1 to hold them all.
Here's a simple FXML layout to demonstrate (borders included):
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.geometry.Insets?>
<?import javafx.scene.layout.*?>
<VBox xmlns="http://javafx.com/javafx/9.0.1" xmlns:fx="http://javafx.com/fxml/1">
<children>
<GridPane gridLinesVisible="true" style="-fx-border-color: black; -fx-border-width: 3;">

So here I have one 3x3 GridPane where each cell is 150x150 pixels. Within each of those 9 cells, I have added another 3x3 GridPane whose cells are each 50x50.
