Let's say I have two of the GridPane and a menu bar up top



// buttons
buttonLaunchOne = new Button("one");
buttonLaunchTwo = new Button("two")

// menu
GridPane menuLayout = new GridPane();
menuLayout.setMinSize(500, 500 );
menuLayout.setAlignment(Pos.TOP_CENTER);
menuLayout.add(buttonLaunchOne, 0, 0);
menuLayout.add(buttonLaunchTwo, 2, 0);

// one
GridPane twoLayout = new GridPane();
resultsLayout.add(buttonOne, 1, 1);

// two
GridPane oneLayout = new GridPane();
profileLayout.add(buttonTwo, 0, 1);


Then I have two action events



buttonLaunchOne.setOnAction(e -> 
 menuLayout.add(firstLayout, 0, 1);
 mainWindow.setTitle("Admin Portal: One");
);
buttonLaunchTwo.setOnAction(e -> 
 menuLayout.add(secondLayout, 0, 1);
 mainWindow.setTitle("Admin Portal: Two");
);


here is the error

I have tried this with a remove statement before adding the layouts and still get the error.
I just want to replace where one layout is with another one when a button is clicked.
I am not sure if what I want to do is really even possible, I just need insight. Thank you and if you need more of the code I have just ask, and I will do so! Thank you!

I have tried this with a remove statement before adding the layouts and still get the error.
I just want to replace where one layout is with another one when a button is clicked.
I am not sure if what I want to do is really even possible, I just need insight. Thank you and if you need more of the code I have just ask, and I will do so! Thank you!

  • I have already added the error code, I edited it before I saw this comment. My bad. This is the only thing that has anything to do with what I need. I will try and add more.
