Can someone plz tell me howto insert into jScrollPane and make the right Layout for the Table????
private void RenewMainTable(){
          remove(jTable1);
          jTable=getJTable1();
          jScrollPane4.setBounds(jTable.getBounds());
          jScrollPane4.setViewportView(jTable);
                //Renew every every Component
                SwingUtilities.updateComponentTreeUI(this);

Answer 1

Der funktionierende Code sieht so aus.
          //delete The Table from Frame and Create a new jTable     
          remove(jTable1);
          jTable=getJTable1();
          //inser new Table into jScrollPane4
          jScrollPane4.setViewportView(jTable);
          //Set the Table to the Position of Table??!!!
          JViewport viewport= jScrollPane4.getViewport();
          viewport.setViewPosition(viewport.getLocation());
          SwingUtilities.updateComponentTreeUI(this);This crazy Code works, the "viewport" Object has Methods to Move the Content inside tthe jScrollPane.
I Said Java to Place jScrollPane4 to the place of jScrollPane4??????? Dont know why it works, but it does.
