У меня проблема с JTable и полосами прокрутки. Я попробовал несколько вещей, теперь это нормально, только если рамка на полной высоте экрана, см. Скриншоты ниже:
Что я пытался добиться этого:
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);
даже расширяет JTable с помощью этого 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;
}
}
Код интерфейса:
public class Fenetre extends JFrame {
частные панели JPanel = новая JPanel (новая 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);

Итак, я не знаю, в чем проблема, так странно. Я жду решений, спасибо.
