Bombe is right… and wrong. I find this whitepaper tends to show off all great features of MiGLayout, entering in nitty gritty details that we would rarely, if ever, use… The paper hesitates between being a tutorial and a reference. Now, the provided demo applications (at MiG Layout main page and MiG Java Components page) … Read more
Set GridBagLayout for JPanel, put JLabel without any GridBagConstraints to the JPanel, JLabel will be centered example import java.awt.*; import javax.swing.*; public class CenteredJLabel { private JFrame frame = new JFrame(“Test”); private JPanel panel = new JPanel(); private JLabel label = new JLabel(“CenteredJLabel”); public CenteredJLabel() { panel.setLayout(new GridBagLayout()); panel.add(label); panel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10)); frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); frame.add(panel); … Read more
Should I completely avoid the use of those methods? Yes for application code. The methods have been defined for a reason. So when should I use them? In which context? For what purposes? I don’t know, personally I think of it as an API design accident. Slightly forced by compound components having special ideas about … Read more
MiGLayout, no doubt. Honestly, it’s the only Swing layout manager I know of that makes any sense. The mere fact that there are 8 layout managers in the core JDK is a good sign that the Swing creators had absolutely no idea about what they were trying to do. This is not to trash the … Read more

from the docs for setReverseLayout Used to reverse item traversal and layout order. This behaves similar to the layout change for RTL views. When set to true, first item is laid out at the end of the UI, second item is laid out before it etc. For horizontal layouts, it depends on the layout direction. … Read more
Currently, StaggeredGridLayoutManager only supports views that span all the columns (for a vertically configured layout), and not an arbitrary number of them. If you still want to span them across all the columns, you should do this in the adapter implementation: public final void onBindViewHolder(RecyclerView.ViewHolder viewHolder, int position) { StaggeredGridLayoutManager.LayoutParams layoutParams = (StaggeredGridLayoutManager.LayoutParams) viewHolder.itemView.getLayoutParams(); layoutParams.setFullSpan(true); … Read more
Simply set location relative to null after calling pack on the JFrame, that’s it. e.g., JFrame frame = new JFrame(“FooRendererTest”); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.getContentPane().add(mainPanel); // or whatever… frame.pack(); frame.setLocationRelativeTo(null); // *** this will center your app *** frame.setVisible(true);
You’re mis-interpreting the information given to you. You should avoid using Swing components with AWT components. It’s OK to use Swing with the AWT listener structure, layout managers, etc. and in fact it’s impossible not to.
Using various LayoutManagers one can provide spacing between various components. 1.) BorderLayout : Overloaded Constructor : BorderLayout(int horizontalGap, int verticalGap) Getter and setter methods For Horizontal Spacing : BorderLayout.getHgap() and BorderLayout.setHgap(int hgap) For Vertical Spacing : BorderLayout.getVgap() and BorderLayout.setVgap() 2.) FlowLayout : Overloaded Constructor : FlowLayout(int align, int hgap, int vgap) Getter and setter methods … Read more
