I’m coding a simple graphics program in Java.

So, I have 3 classes.

  1. The first class is the GUI w/c extends JFrame, it load the menu bar and panel (drawing class)

  2. The second class is the drawing class, it extends JPanel, and it has simple Graphics commands.

  3. The third class is an animation class, it displays an animation. It also extends JPanel.

So my question is this, how do I display the animation class in the panel of the GUI class. I want it to be displayed instead of drawing class. When I try to place it there, it displays a tiny box beside the drawing class panel. I am not very good at frames and panels. Thank you very much in advance!

    All JPanels have a LayoutManager which, rather handily, manages how Components are laid out. The default layout is FlowLayout, which default mode will simply place each component to the right of the last component.

    If you want to change the layout to something more useful, there are many options; BorderLayout, GridLayout, GridBag layout are popular ones. Myself, I use MigLayout, an external library which is very powerful :).

    As for it appearing small, try manually enforcing the size with setSize(w, h) or setPreferredSize(w, h).
