  <p>What I am trying to achive, is to get a BoxLayout at the top left corner, which has two columns - Button and TextInput NEXT TO it. However, it only does all components one under each other. I have also a future question on how to add another BoxLayout NEXT TO the previous BoxLayout that I have. As in - how to make it be on the right side of existing BoxLayout, how to position it.</p>
