How do I modify and redraw a GridPane in JavaFX
I am trying to create the standard mouse maze solver for a class and I am having troubles with the graphical part. Solving the maze is easy but updating the mouse graphically as he moves is proving tough to do. Below is a stripped down version of what I have.
@Override
public void start(Stage primaryStage) throws IOException {
Maze maze = new Maze();
maze.loadMazeFromFile("maze_input.txt");
GridPane mazeGrid = maze.drawGrid();
mazeGrid.setAlignment(Pos.CENTER);
StackPane root = new StackPane();
root.getChildren().add(mazeGrid);
Scene scene = new Scene(root, (maze.rows()*10)+40, (maze.columns()*10)+130);
primaryStage.setTitle("Mad Mouse Maze");
primaryStage.setScene(scene);
primaryStage.show();
maze.solveMaze();
}
A simple window opens with my maze displayed in it and the mouse can solve the maze as seen in the console output, all that works fine. What I need to do and can't figure out how to do is repeat mazeGrid = maze.drawGrid();
every time the mouse moves within maze.solveMaze();
and redraw the GridPane representing the maze. How do I get access to mazeGrid from within a maze object? Do I create some type of event for the grid to watch for and fire it, if so how? Getting access to elements in a window is extremely difficult in JavaFX which tells me I am doing something wrong. please help.
