Hey, so while attempting to make my gui i have encountered a problem. when i call the gui to appear using gui.setvisible(true) I get a weird version where nothing pops up but it says that there is an open window in my open programs bar thing (picture for reference, the gui is the thing on window on the right). my Gui class is named "Gui" and is in the same package as the main class.

 

i also call it by using "public Gui gui = new Gui();" at the top of main before onStart()

 

in onStart the gui is set to visible with: "gui.setVisible(true);"

 

its weird because i use the gui the same way i did in other scripts and it worked fine there.

 

just wondering if anyone else has had this weird problem.

Make sure your GUI extends JFrame

We will need to see some code to determine the issue. 

 

One reason could be that you have not set a size on your JFrame?

gui.setMinimumSize(new Dimension(500, 500));

GUI gui;
	
	@Override
	public void onStart() throws InterruptedException {
		
		gui = new GUI();
		
	}

:edit: if that doesn't fix it, then I'll need to see your code.
