问题
Please, I want to display the labels' text vertically.
Also I want the column header to be displayed vertically.
actually, I tried to use:
public static final String LOGO_PATH = "/org/optaplanner/examples/curriculumcourse/swingui/curriculumCourseLogo.png";
private final TimeTablePanel<Room, Period> roomsPanel;
private final TimeTablePanel<Teacher, Period> teachersPanel;
private final TimeTablePanel<Curriculum, Period> curriculaPanel;
public CurriculumCoursePanel() {
setLayout(new BorderLayout());
JTabbedPane tabbedPane = new JTabbedPane();
roomsPanel = new TimeTablePanel<Room, Period>();
tabbedPane.add("Rooms", new JScrollPane(roomsPanel));
teachersPanel = new TimeTablePanel<Teacher, Period>();
tabbedPane.add("Teachers", new JScrollPane(teachersPanel));
curriculaPanel = new TimeTablePanel<Curriculum, Period>();
tabbedPane.add("Curricula", new JScrollPane(curriculaPanel));
add(tabbedPane, BorderLayout.CENTER);
setPreferredSize(PREFERRED_SCROLLABLE_VIEWPORT_SIZE);
}
@Override
public boolean isWrapInScrollPane() {
return false;
}
@Override
public boolean isRefreshScreenDuringSolving() {
return true;
}
private CourseSchedule getCourseSchedule() {
return (CourseSchedule) solutionBusiness.getSolution();
}

roomsPanel.reset();
teachersPanel.reset();

defineGrid(courseSchedule);
fillCells(courseSchedule);
repaint(); // Hack to force a repaint of TimeTableLayout during "refresh screen while solving"
}

I've tried to change the SwingConstants.CENTER to be SwingConstants.VERTICAL, but the following error is received:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: horizontalAlignment
at javax.swing.JLabel.checkHorizontalKey(Unknown Source)
at javax.swing.JLabel.setHorizontalAlignment(Unknown Source)
at javax.swing.JLabel.<init>(Unknown Source)
at javax.swing.JLabel.<init>(Unknown Source)
what I need is to display the labels to be written as in Excel when you align the cell's contents to be displayed from top to bottom as if it has been rotated 90 degree.
