java Jtable JscrollPane the JTable displaying at full screen height

I have a problem with the JTable and scrollbars i tried several things now it's ok only if the frame is at full screen height see the screenshots below :

enter image description here

full height

What i tried to achieve this :

 Dimension dim = new Dimension(400,350);
    tableProd.setSize(dim);
    tableProd.setPreferredSize(dim);
    tableProd.setMinimumSize(dim);
    tableProd.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
    tableProd.setModel(modeleDatas);
    tableProd.setPreferredScrollableViewportSize(dim);

    JScrollPane scrollTab=new JScrollPane(tableProd);    
    scrollTab.setPreferredSize(dim);

    panelProd.add(scrollTab, gbc);

even extends JTable with this JSTable :

public class JSTable extends JTable {

/**
 * Returns false to indicate that horizontal scrollbars are required
 * to display the table while honoring perferred column widths. Returns
 * true if the table can be displayed in viewport without horizontal
 * scrollbars.
 * 
 * @return true if an auto-resizing mode is enabled 
 *   and the viewport width is larger than the table's 
 *   preferred size, otherwise return false.
 * @see Scrollable#getScrollableTracksViewportWidth
 */
public boolean getScrollableTracksViewportWidth() {
if (autoResizeMode != AUTO_RESIZE_OFF) {
    if (getParent() instanceof JViewport) {
    return (((JViewport)getParent()).getWidth() > getPreferredSize().width);
    }
} 
return false;
}

}

UI code :

 public class Fenetre extends JFrame {

private JPanel panels = new JPanel(new CardLayout()); 

    public Fenetre(){

    this.setTitle("Gestion Station Phone");
    this.setSize(900, 800);
    this.setLocationRelativeTo(null);
    this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    initMenu();
    this.setJMenuBar(menuBar);

    panels.add(cardHome,BorderLayout.CENTER);
    panels.add(cardBD,BorderLayout.CENTER);
    panels.add(cardVente, BorderLayout.CENTER);

    cardHome.setVisible(true);
    cardBD.setVisible(false);
    cardBD.setVisible(false);

So, i don't know what is the problem so weird. I'm waiting for solutions thanks.

Solution

  • You need to properly configure the layout manager of the parent container that holds the JScrollPane (which in turn holds your JTable). From line

    panelProd.add(scrollTab, gbc);

    in your first code snippet, I guess the parent container is panelProd and its layout manager is a GridBagLayout. Thus you need to properly configure the GridBagConstraints instance (which I guess is gbc) associated to your scroll pane. You probably need something like

    gbc.fill = GridBagConstraint.BOTH;
gbc.weightx = 1;
gbc.weighty = 1;
panelProd.add(scrollTab, gbc);

    Do not set preferred sizes for your scroll pane and your table in this case!!

    However, without knowing the rest of the code that populates panelProd it is impossible to tell for sure.

    Edit to reflect additional source code in original question:

    Replace the code from line

    panelProd.setLayout(new GridBagLayout());

    to line

    cardBD.add(panelProd,gbcPage);

    with

    JPanel panelProd = new JPanel(new BorderLayout());
tableProd.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
tableProd.setModel(modeleDatas);
panelProd.add(labelProd, BorderLayout.NORTH);

JScrollPane scrollTab=new JScrollPane(tableProd);    
panelProd.add(scrollTab, BorderLayout.CENTER);

int oldFill = gbcPage.fill;
double oldWeightX = gbcPage.weightx;
double oldWeightY = gbcPage.weighty;

gbcPage.fill = GridBagConstraints.BOTH;
gbcPage.gridx=2;
gbcPage.gridy=1;
gbcPage.gridwidth=1;
gbcPage.weightx=1;
gbcPage.weighty=1;
cardBD.add(panelProd,gbcPage);

gbc.fill = oldFill;
gbc.weightx = oldWeightX;
gbc.weighty = oldWeightY;

    GridBagLayout is not necessary for simple arrangements like your prodPanel (BorderLayout is sufficient and much simpler to use in this case).
