特にやりたいことについて質問を投稿したいのですが、JTables. これは私が持っているものです：
しかし、テーブルを次のように配置したいと思います。
そのため、特定の日付の下で、上記のように個別に表示されるのではなく、その日付に対応するすべてのイベントが表示されます。
問題の関連クラスは次のとおりです。上記を達成できるようにするために、どこでどのように変更を行うべきかわかりません。
public class DbUtils {
public static TableModel resultSetToTableModel(ResultSet rs) {
try {
ResultSetMetaData metaData = rs.getMetaData();
int numberOfColumns = metaData.getColumnCount();
Vector columnNames = new Vector();
for (int column=0; column < numberOfColumns; column++) {
columnNames.addElement(metaData.getColumnLabel(column + 1));
}
Vector rows = new Vector();
while(rs.next()) {
Vector newRow = new Vector();
for (int i =1; i <= numberOfColumns; i++) {
newRow.addElement(rs.getObject(i));
}
rows.addElement(newRow);
}
return new DefaultTableModel(rows,columnNames);
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
}
public class EventModel {
public TableModel getTableData() {
TableModel model=null;
try {
String sql = "SELECT eventID as 'Event ID', date as 'Date',eventName as 'Name', time as 'Start Time' FROM Event";
pst = conn.prepareStatement(sql);
rs = pst.executeQuery();
model = (DbUtils.resultSetToTableModel(rs));
}
catch(SQLException e){
e.printStackTrace();
}
finally {
try {rs.close(); pst.close();}
catch(SQLException e){} }
return model;
}
public Events getEvent(String tableClick) {
try {
pst = conn.prepareStatement("SELECT * FROM Event WHERE eventID='"+tableClick+"' ");
rs = pst.executeQuery();
while(rs.next()){
e.setEventName(rs.getString(2));
e.setEventDate(rs.getString(3));
e.setEventTime(rs.getString(4));
e.setEventVenue(rs.getString(5));
e.setEventDetail(rs.getString(6));
e.setEventOpportunity(rs.getString(7));
e.setEventMoreDetails(rs.getString(8));
e.setEndTime(rs.getString(9));
}
}
catch(SQLException ex){
ex.printStackTrace();
} finally {
try {
rs.close();
pst.close();
} catch (Exception e) {
}
}
return e;
} //end getEvent
}
public class EventController {
private KeyAdapter keyAdapter = new KeyAdapter() {
@Override
public void keyReleased(java.awt.event.KeyEvent e) {
if((e.getKeyCode()==KeyEvent.VK_UP) || (e.getKeyCode()==KeyEvent.VK_DOWN)) {
changeEvent();
}
}
};
public void changeEvent() {
int rowSelected = view.tableEvent.getSelectedRow();
tableClick = view.tableEvent.getModel().getValueAt(view.tableEvent.convertRowIndexToModel(rowSelected), 0).toString();
events = model.getEvent(tableClick); //tell model to change its state based on user input on views
view.changeDisplay(events);
}
}
public class EventView {
public void changeDisplay(Events e) {
evTitle.setText(""+e.getEventName());
evWhen.setText("When: "+ e.getEventDate());
evWhere.setText("Where: "+ e.getEventVenue());
evDescription.setText(""+ e.getEventDetail());
evOpportunity.setText(""+ e.getEventOpportunity());
evMoreDet.setText(""+ e.getEventMoreDetails());
endTime.setText("End Time: "+e.getEndTime());
}
}
eはただの .Events クラスのオブジェクトですbean。
