Modal JDialog shows empty frame. Contained Panels are not showing

Okay so I've successfully created a modal JDialog and I used Netbeans GUI Builder to create panels to speed up the design. However, the modal JDialog doesn't show the panels it has, therefore empty. I don't know what to do next and I don't see any reason why it won't show up if the main container does show.

JDialog is expected to come up after 2 mouse clicks on JTable

What comes up is this.

instead of this (Update Curriculum Gui), below.

enter image description here

private void curriculumListJtblMouseClicked(java.awt.event.MouseEvent evt) {                                                
        int clickCount = evt.getClickCount();
        if (clickCount == 2) {
            UpdateCurriculumGui updateCurriculum = new UpdateCurriculumGui();
            updateCurriculum.setPreferredSize(new Dimension(1000, 650));
            updateCurriculum.setVisible(true);
            updateCurriculum.pack();
            updateCurriculum.setLocationRelativeTo(null);
        }
    }

UpdateCurriculumGui on it's own class.

public class UpdateCurriculumGui extends javax.swing.JDialog {



    public UpdateCurriculumGui() {
        super(null, ModalityType.MODELESS);
        setAlwaysOnTop(true);
        setTitle("Update Curriculum Information");
    }
}

I hope you can help me because I haven't tried to use JDialogs before. I'd appreciate any suggestions.

Thanks.

Solution

  • you have to fill your dialog with content!

    public class UpdateCurriculumGui extends javax.swing.JDialog {

    public UpdateCurriculumGui() {
        super(null, ModalityType.APPLICATION_MODAL);
        //setAlwaysOnTop(true); set modal instead
        setTitle("Update Curriculum Information");
        add(new JLabel("i'm content!"));  //this is content!      
    }
}

    see Dialog.ModalityType for details on MODELESS (shouldn't it be APPLICATION_MODAL ?)
