I have been trying for hours to find a way to solve the issue, but I had no luck with that. Here is a sample code: import java.awt.BorderLayout; import javax.swing.BoxLayout; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JScrollPane; import javax.swing.SwingUtilities; public class Example extends JFrame { private static final long serialVersionUID = 1L; public Example() { JPanel contentPane = (JPanel) getContentPane(); contentPane.setLayout(new BorderLayout()); JPanel panTop = new JPanel(new BorderLayout()); //JPanel panBottom = new JPanel

here's an SSCCE: import java.awt.Color; import java.awt.Dimension; import javax.swing.Box; import javax.swing.BoxLayout; import javax.swing.JButton; import javax.swing.JComboBox; import javax.swing.JFrame; import javax.swing.JPanel; public class BoxLayoutTest extends JFrame { public BoxLayoutTest(){ JPanel main = new JPanel(); main.setLayout(new BoxLayout(main, BoxLayout.Y_AXIS)); main.setBackground(Color.red); this.add(main); JPanel northPanel = new JPanel(); JPanel middle = new JPanel(); middle.setLayout(new BoxLayout(middle, BoxLayout.X_AXIS)); middle.add(new JButton("FOO")); middle.add(Box

I am learning Java Swing and I appended a menuBar to the frame. By default this should call jframe.getContentPane().add(child) . When I ran the script the menuBar didn't show up. But the button was at the very top "y=0" if that makes sense. Then I realized my mistake I actually had to put in a menu in the menubar. Then the menuBar showed up. So that got me thinking...is the "menubar" "contentpane" actually 2 panels? It is confusing the hell out of me. Because that acted a lot like a panel. But getContentPane() returns a Container, not a JPanel object so I'm confused. If so, does that mean that

The CA Programming Guide is talking about Constraints Layout Managers. However, the CALayer in the iPhone SDK doesn't have any constraints property or addConstraint method. They say iPhone OS just doesnt provide custom layout managers. But how about the standard ones? Unfortunately, despite the documentation saying so, even the springs-and-struts layout of layers is missing from the iPhone implementation of CALayer. This can be seen by the missing autoresizingMask property on CALayer on the iPhone. For Core Plot , we implemented our own custom layer layout via the -layoutSublayers method of

I am trying to achieve following structure (image below). As you can see there are two sections with RecyclerView s and CardView s in it. These two sections are divided by two TextView s with Button s. Each section should match screen width (minus indent between cards). Each CardView has square ImageView in it. So the height of CardView itself depend on screen width: card_height = screen_width - indent_between_cards + space_for_card_text . To achieve this behaviour I use simple SquareImageView , which looks like this: public class SquaredImageView extends ImageView { public SquaredImageView
