Eclipse WindowBuilder Not Resizing Frame

Question

Here's the code migrated from Netbeans to Eclipse 4.3 and WindowBuilder

I can't resize the Frame from GUI and I don't really understand why it isn't possible, when I select the root Frame and drag the edges, the frame won't update at all.

Does it have anything to do with using a LayoutManager properly? As far as I could tell, WindowBuilder isn't accessing or editing the .form file generated by Netbeans

public class ExploreDBX extends javax.swing.JFrame {

    /**
     * Creates new form ExploreDBX and runs the alteration function
     */
    public ExploreDBX() {
        initComponents();
    }

    /**
     * This method is called from within the constructor to initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is always
     * regenerated by the Form Editor.
     */

later edit # 1

created a new file, tested and resize works, i need to figure out what causes this problem and decide if I should redo the whole interface and maybe tidy it up a bit

Answer 1

You have a call to setResizable(false) inside your initComponents Method. Remove that and it will work.

WindowsBuilder does not use .form files at all. Eclipse and Netbeans have different implementations of a GUI builder.

Answer 2

This issue is caused by the pack(); call at the end of the constructor. Remove it and resizing will work as expected.
